Review of cestodes (Platyhelminthes: Cestoda) recorded from birds in Sakar Mountains
2024 ZooNotes Supplement 15: 7-19: MARGARITA H. MARINOVA
Abstract. A
review of cestodes (Platyhelminthes: Cestoda) recorded from birds in
Sakar Mountains is presented. A total of 31 species were reported as
two of them has been identified at the generic level only. They belong
to 21 genera and 4 families of the order Cyclophyllidea. As hosts, 39
species of bird from 19 families were reported. A host-parasite list is
presented. The cyclophyllidean cestode species from birds recorded in
the Sakar Mountains represent 13.6% of the cestode species recorded in
Bulgaria.
Physiological measurements of the Mediterannean mussel (Mytilus galloprovincialis Lamarck, 1819) from the Bulgarian Black Sea as biomarkers for multi-stressor environment
2024 ZooNotes 238: 1-4: VESELA YANCHEVA, ILIANA VELCHEVA, ELENKA GEORGIEVA, STELA STOYANOVA, BORISLAVA TODOROVA, KRISZTIAN NYESTE, LASZLO ANTAL
Abstract. Wild
and farmed mussels from the Bulgarian Black Sea were collected to study
and compare the survival rates (stress on stress response) as a
biomarker for multi-stressor environment. In sum, the survival time
indicated that the farmed mussels were more tolerant to stress, even
though they had a similar size and lived in similar conditions. Further
research needs to be done to clarify why.
A new
collection of Psocodea (Insecta) from Unguja Island (Zanzibar, Tanzania)
2024 ZooNotes 237: 1-4: DILIAN GEORGIEV
Abstract. The study presents a new collection of Psocodea
(Insecta) from Unguja Island (Zanzibar, Tanzania), conducted during March 3rd
to 9th, 2024. Despite recent efforts to explore Psocodea fauna in equatorial
and tropical Africa, comprehensive studies in East Africa, particularly along
the east coast and inland areas, remain limited. This research contributes to
filling these gaps by documenting 16 species, including nine new records for
the Zanzibar autonomic region and seven new records for Tanzania. Notably, one
species (Nanopsocus sp.) may
potentially be new to science.
A case
of transportation of Cimex hemipterus
(Fabricius, 1803) (Insecta, Hemiptera) in Bulgaria
2024 ZooNotes 236: 1-2: DILIAN GEORGIEV
Abstract. During the period of 02-09.03.2024, the author
and their family stayed in a hotel infested with bed bugs in Uroa village,
Unguja Island, Zanzibar. Upon returning to Bulgaria (Hrishteni village, Stara
Zagota city area), one specimen of Cimex
hemipterus (Fabricius, 1803) was found alive in the luggage. This should be the first documented record of
the tropical bed bug in Bulgaria, and the possibility of transfer via increased
touristic visit in tropical destinations were briefly discussed.
Abundance
and biomass of Cladocera (Crustacea) in Vaya Lake
Abstract. The number and biomass of Cladocera in Vaya Lake
during the period 2003 - 2007 was studied under the conditions of increased
anthropogenic pressure. The total number of cladocerans by station and
by species, as well as their biomass, was determined. A dendrogram of
similarity in species and quantitative composition of Cladocera was made. St. 1
and St. 5 are distinguished by the equal and lowest abundance of D. magna, and the very similar and
highest abundance of M. micrura.
Stations 3, 4, 11, and 12 had the highest Cladocera abundances, which were
mainly due to close D. longispina and
M. micrura. St. 9, 8, 2 and 7 form
one group with more than 83% similarity. They show similar abundances of D. pulex. The dendrogram of similarity
in species composition and biomass for the cladocerans showed 75% similarity
among all stations except st. 5, which clearly stands out with the lowest total
biomass.
Recent
record of Leioderes kollari kollari
L. Redtenbacher, 1849 (Cerambycidae: Cerambycinae) in Bulgaria
Abstract. The
longhorn beetle species Leioderes kollari
kollari L. Redtenbacher, 1849 (Cerambycidae: Cerambycinae) is reported in
Bulgaria after nearly thirty years of lack of data. Beetles were collected with
UV light traps in the Shumensko Plato Nature Park with preserved natural forest
habitats. The habitat of the species in the studied area is a mixed deciduous
forest with Fagus sylvatica L., Carpinus betulus L. and Acer campestre L.
Current
distribution of Chukar Partridge (Alectoris
chukar J.E. Gray, 1830) in Sakar Mts, Southeast Bulgaria
Abstract. The
distribution and degree of breeding evidence of Chukar Partridge was identified
by field observations in the period 2019-2023 in the area falling within the
natural habitats of the species in Sakar Mountain. For the entire study period,
a total of 22 different localities of the species with a certain breeding
category were established and in 8 of them there was confirmed breeding. The
average number of fledglings per successfully bred pair is 8.37±2.2 (6-12
ind.). Non-pairing and non-breeding
birds were also observed in 2021/2022 at sites where breeding success data were
collected.
First
record of Vadonia unipunctata makedonica
Holzschuh, 1989 (Cerambycidae: Lepturinae) in Bulgaria
Abstract. Vadonia unipunctata
makedonica
Holzschuh, 1989 (Cerambycidae: Lepturinae) is reported from the Bulgarian part
of Falakro Mts. The nominative subspecies V.
unipunctata unipunctata (Fabricius, 1787) is also present in Bulgaria.
Photographs of the beetles of both subspecies are provided.
Seasonal
and circadian activity patterns of two sympatric carnivores in an agricultural
habitat, Southern Bulgaria
Abstract. To establish the circadian activity of the Red Fox (Vulpes
vulpes) and the Stone
Marten (Martes
foina) in agricultural habitats of Southern Bulgaria a total of 5 camera
traps were set in protected area “Maritsa - Parvomay”. Both carnivores
demonstrated bimodal nocturnal activity with close or coincident hour
intervals. They showed peak activity in the dark and in the twilight, which is
usual for areas with strong anthropogenic influence.
One more “Asian” psocid (Insecta: Psocodea) found in Africa?
Abstract. The
study presents new findings of Peripsocus cf. constrictus Thornton
& Wong, 1968, in Uganda, near Buvi village, along the shores of
Lake Victoria. Specimens were collected on July 30th, 2022, from a
swampy area with bushes, palms, and various hygrophytes. A total of 12
female specimens were collected by beating the vegetation and stored
for further analysis. The species P. constrictus was previously
described based solely on a male specimen from Southeast Asia, so its
identification based on females from Africa remains uncertain.
A record
of import of the invasive snail Theba
pisana (O. F. Müller, 1774) (Gastropoda: Helicidae) in Bulgaria
Abstract. This is a short communication of a discovery of
the invasive Mediterranean snail species Theba
pisana among
food products in a market in Bulgaria imported from Spain. A single live
juvenile specimen was found among lettuce leaves. Later it was alive kept in a
terrarium.
Nesting observation of the Sculptured
Resin bee Megachile sculpturalis F.
Smith, 1853 (Hymenoptera: Megachilidae) in Bulgaria
Abstract. Establishing of the East Asian bee species Megachile sculpturalis F. Smith, 1853
(Hymenoptera: Megachilidae) is documented in Bulgaria. Nesting of the species on
two old trees of Styphnolobium japonicum
(L.) Schott was observed in the Sea Garden of Varna City, NE Bulgaria. A single
female of the same species was also collected in Banitsa Vill., NW Bulgaria.
Notes on the diet of Testudo hermanni boettgeri and T. graeca ibera in south-western Bulgaria with first cases of geophagy and myrmecophagy from the country
2023 ZooNotes 228: 1-4: EMANUIL MITREVICHIN, LIDIA SAKELARIEVA, HRISTO PESHEV, ALEXANDER PULEV
Abstract. Data on the diet of Testudo hermanni and T. graeca have been published in Bulgaria
for more than a century. Yet, few studies have provided more details on the feeding
habits of the two species. Here, we present information about their diet in
south-western Bulgaria where they coexist. The results showed that T. graeca
fed exclusively on plants, whereas T.
hermanni was more opportunistic and
supplemented its diet with other food sources, including ants and soil
particles.
New records of Agapanthia maculicornis maculicornis (Gyllenhal, 1817) (Cerambycidae: Lamiinae) in SE Bulgaria
2023 ZooNotes 227: 1-4: DENIS GRADINAROV, YANA PETROVA
Abstract. Eight new localities of Agapanthia maculicornis maculicornis (Gyllenhal, 1817)
(Cerambycidae: Lamiinae) in SE Bulgaria are reported. The species is rather
common in xerothermic herbaceous communities, being most often found on plants
from the tribe Cichorieae (Asteraceae: Cichorioideae). Photographs of the
species from Bulgaria are published for the first time.
Exposure to polybrominated diphenyl ethers impairs the health condition of Zebra Mussel, Dreissena polymorpha (Pallas, 1771)
2023 ZooNotes 226: 1-4: VESELA YANCHEVA, ILIANA VELCHEVA, ELENKA GEORGIEVA, BORISLAVA TODOROVA, KRISZTIÁN NYESTE, LÁSZLÓ ANTAL, STELA STOYANOVA
Abstract. Тhe present pilot laboratory study (96 hours and
30 days) aimed to provide for the first time the possible adverse effects of
different concentrations of PBDEs congers (PBDE 28, PBDE 47, PBDE 99, PBDE 100,
PBDE 153, PBDE 154), based on Water Framework Directive 2000/60/EC (WFD) in Zebra
Mussels (Dreissena polymorpha Pallas,
1771). Thus, we calculated different condition factors
based on the mussel’s weight and length to determine the possible adverse
effects of acute and subchronic exposure to PBDEs under laboratory conditions.
Earthworm (Clitellata: Lumbricidae) records from the Western Stara Planina Mts (Bulgaria)
2023 ZooNotes 225: 1-4: HRISTO VALCHOVSKI, NIKOLAY KODZHABASHEV, KALINA KOCEVA
Abstract. The
current study is
a contribution to the knowledge of the earthworm diversity from the Sofia
region (Bulgaria).

(near Montjoly town and Wayki village) by beating the vegetation between
29.07-05.08.2023. At least 14 species from seven families of Psocoptera were
collected. Nine of them were new records for French Guiana (four new records
for the New World) and five were already known for this area.
Animal remains of the Late Antiquity settlement (1-4th c. AD) near Dolni Lukovit (Pleven Region, CN Bulgaria)
2023 ZooNotes 222: 1-2: ZLATOZAR BOEV
Abstract. A total of 29 bones and bone fragments of wild
and domestic birds and mammals collected in the Late Antiquity military
settlement near Dolni Lukovit village (Pleven Region, CN Bulgaria) have been
identified as 9 species of 7 orders. Most numerous are the remains of pigs and
chickens. The species composition suggests the existence of open treeless
grassy habitats in the vicinity of settlements.

cetacean feeding.
Data on migration and wintering of the Common Crane (Grus grus Linnaeus, 1758) in Northwestern Bulgaria
2023 ZooNotes 219: 1-4: GEORGI STOYANOV, KRASIMIR DONCHEV
Abstract. In the period 2011 - 2022, four cases of
nocturnal flight and two cases of daytime observations during autumn migration
of Common Crane (Grus grus Linnaeus,
1758) were registered in Northwestern Bulgaria. One case of this species
wintering in NW Bulgaria has also been observed. The data available so far are
very limited regarding the migration and wintering of the Common Crane in this
part of Bulgaria.
Biomass of the chironomid larvae (Chironomidae, Diptera) in Vaya Lake (Bulgaria) during the period 2003-2007
2023 ZooNotes 218: 1-4: ELENA NENOVA, STEFAN STOICHEV
Abstract. The biomass of chironomids in the Vaya Lake during
the period 2003-2007 was studied. In the spring and summer of 2004, the biomass
was estimated by the highest values, and in the spring and summer of 2006 – the
lowest. The species with the greatest participation in the biomass were: Chironomus riparius, Cryptochironomus defectus, Chironomus gr. plumosus, Cricotopus
sylvestris, Tanytarsus gregarious
and Cricotopus algarum. The stations
along the central axis of the lake had the highest similarity. Dendrogram of
chironomid biomass similarity showed high similarity (greater than 80%) for
sites 3, 4 and 12.

Chronic toxicity of microplastics have lethal effects on common carp (Cyprinus carpio Linnaeus, 1785)
2023 ZooNotes 216: 1-4: VESELA YANCHEVA, BORISLAVA TODOROVA, DOBRINKA TODOROVA-BAMBALDOKOVA, ELENKA GEORGIEVA, ILIANA VELCHEVA, STELA STOYANOVA
Abstract. The 21st century has seen the
realization that people have overused plastic. Unfortunately, plastic pollution
is a widespread environmental problem in many of the world’s rivers and seas.
Plastic litter is well distributed in shallow as well as in deep-waters, and
therefore it is inevitably present in the world’s ocean which is in turn the
final sink of plastic debris of all sizes, alongside other various
anthropogenic toxicants (for example, heavy metals and persistent organic
pollutants). The negative effects of microplastics (MPs) which are produced by
the breakdown of larger plastic debris on aquatic organisms, including both freshwater
and marine fish have been already well documented. However, there is a gap in
the knowledge from studies conducted in the field or under laboratory
conditions in Bulgaria.

activity of the Red fox (Vulpes vulpes)
and the Stone marten (Martes foina)
in the protected area "Zlatiyata", situated in an agricultural
landscape. The study was conducted from September 2021 to March 2022 using
camera traps. It provides new data on the behavioral ecology of the target
species contributing to the knowledge of their co-existence in croplands.
Coturnix coturnix (Linnaeus, 1758) - the common known bird? Part III. Common quail hybridization aspects
2022 ZooNotes 208: 1-3: HRISTO LUKANOV, IVELINA PAVLOVA
Abstract. The common quail (Coturnix coturnix Linneaus, 1758) belongs
to a genus with a small variety of species, inhabiting a huge area, which has
given the opportunity to distinguish several subspecies. An important element for
the common quail’s population diversity, which is relatively poorly studied, is
the possibility of inter-species hybridization and intraspecies crossbreeding.
The main scientific focus is in the direction of relationship between common
and Japanese quail. The analysis of possible other possibilities of
interaction between the different species of the genus Coturnix and the separate subspecies gives serious grounds for a
far broader consideration of the common quail hybridization issue.
First observation of the White-tailed eagle Haliaeetus albicilla (Linnaeus, 1758) in CW Bulgaria for the last 132 years
2022 ZooNotes 207: 1-4: ZLATOZAR BOEV, ZLATOZAR BOEV Jr.
Abstract. An
observation of an adult bird on the 20th August 2022 along the shore
of Bozalan (Bakardere) Reservoir near Verinsko village (CW Bulgaria) is
reported. This is the first species’ record in the last 132 years in that part
of the country.
A Case of winter activity of the Hermann’s Tortoise (Testudo hermanni Gmelin, 1789) (Reptilia: Testudinidae) from Bulgaria
2022 ZooNotes 206: 1-4: EMANUIL MITREVICHIN, LIDIA SAKELARIEVA, ALEXANDER PULEV
Abstract. The active season of T. hermanni in Bulgaria is from March–April to October–November. So
far, few cases of winter activity have been registered in the country. Here we
report on another such case of an adult T.
hermanni. The temporary emergence of the specimen from its hibernaculum was
probably caused by the combined effect of several factors such as the high
ambient temperatures, the orientation of the slope, the altitude, the depth of
the hibernaculum used, etc.
Scavenging behavior of an adult Hermann’s Tortoise (Testudo hermanni Gmelin, 1789) (Reptilia: Testudinidae)
2022 ZooNotes 205: 1-4: EMANUIL MITREVICHIN, LIDIA SAKELARIEVA, ALEXANDER PULEV
Abstract. It is well known that the Hermann’s Tortoise (Testudo hermanni) feeds primarily on
plants. The species can also supplement its diet with different food sources,
including carrion. Yet, few cases of scavenging behavior have been reported in
the literature. Here we report on the consumption of a dead female Common Toad
(Bufo bufo) by an adult female T. hermanni. The scavenging behavior
observed can be related to the increased energy needs of females during the
nesting season.
Coturnix coturnix (Linnaeus, 1758) - the common known bird? Part II. Common quail taxonomy
2022 ZooNotes 204: 1-3: HRISTO LUKANOV, IVELINA PAVLOVA
Abstract. Despite the controversy over Common quail (Coturnix coturnix Linneaus, 1758)
subspecies diversity, the following subspecies stand out in the scientific
literature: C. c. coturnix (Linneaus,
1758), C. c. africana (Temminck &
Schlegel, 1848), C. c. erlangeri
(Zedlitz, 1912), C. c. inopinata
(Hartert, 1917), and C. c. conturbans
(Hartert, 1917). This systematics is based on the area of distribution and
insignificant external differences, which is criticized for the migratory
behavior of the species and the opportunities for interspecies contact in the
common areas.
Observations of terrestrial vertebrates at South Coastal Kenya: a short note
2022 ZooNotes 203: 1-4: DILIAN GEORGIEV
Abstract. In terms of the biodiversity monitoring and
conservation, localities of 9 species of reptiles, 26 species of birds, and 9

Island).
Faunistic and ecological investigations of the free-living freshwater nematode fauna of the Ogosta Reservoir (North-West Bulgaria)
2022 ZooNotes 202: 1-4: STEFAN STOICHEV, HRISTINA KALCHEVA, ELENA NENOVA
Abstract. The
study gives for the first time a short hydrofaunistic investigation of the
Ogosta Reservoir, recently infested by the invasive species from complex Dreissena
bugensis -polymorpha. A
total of 22 nematode species belonging to 12 genera and 9 families were found
for the period April 2010 and August 2012. Nematode fauna and environmental
factors were tested by statistical analyses. The species Monhystera stagnalis, M.
filiformis and Dorylaimus stagnalis
were found in all five stations of the reservoir. One species, Rhabditis brevispina, is new to the
Bulgarian hydrofauna.
Coturnix coturnix (Linnaeus, 1758) - the common known bird? Part I. Distribution and conservation status
2022 ZooNotes 201: 1-3: HRISTO LUKANOV, IVELINA PAVLOVA
Abstract. Common
quail (Coturnix coturnix Linneaus,
1758) inhabits a vast area spread over three continents - Europe, Asia and
Africa. Although it is the most thoroughly studied wild representative of the
genus Coturnix there are some poorly
clarified aspects, mainly concerning its current conservation status,
subspecies diversity, and the possibilities for natural hybridization. The
purpose of this article is to consolidate, systematize and analyze the
available information regarding the state of the global population, taxonomy,
and the hybridization of the common quail.
Mass winter movements of Yelkouan Shearwaters (Puffinus yelkouan) along the Bulgarian Black Sea coast
2022 ZooNotes 200: 1-3: PETER SHURULINKOV, ROSSEN TZONEV, GIRGINA DASKALOVA, PETKO TZVETKOV, ZHIVKO GRADINAROV
Abstract. Large
flocks of Yelkouan Shearwaters (Puffinus
yelkouan Acerbi, 1827) were reported to migrate along the northern
Bulgarian Black Sea coast in the winter. On 06.02.2021, a total of 15,488
Yelkouan Shearwaters were counted for one hour after midday at Dobrudzha
campsite, Shabla. During February 2021 and 2022, some smaller flocks were also
observed. In the past, such big concentrations of Yelkouan Shearwaters in the
Black Sea have been reported only during the spring, summer and rarely autumn.
The possible explanations for such a winter influx of the species are
discussed.

Another
contribution to the knowledge of the trophic spectrum of few
lacertid lizards (Reptilia, Squamata, Lacertidae) from
Southern Bulgaria
Abstract. We present
unpublished data on the diet of three lizards (Lacerta
trilineata, Lacerta agilis and Podarcis
tauricus) from the Lacertidae family, collected in 1974
in few localities in Southern Bulgaria. The analyzed data
showed that the insects (Insecta) are the most numerous and
the most frequently met food component and among the
non-insect components the spiders and isopods are slightly
predominating. The largest niche breadth was recorded in Podarcis
tauricus (6.135), followed by Lacerta trilineata
(5.263) and Lacerta agilis (4.132). All three studied
lacertid species are classified as opportunistic general
feeders (polyphages), which may show slight preference towards
beetles, ants or spiders, depending on the occupied habitat or
the season.

Toxic pesticides effects on the respiration rate in Dreissena polymorpha (Pallas, 1771)
2021
Abstract. With the present
experiment we aimed to study the possible negative effects of
two commonly used insecticides – cypermethrin (CYP) and
chlorpyrifos (CPF) on the respiration rate of Zebra Mussel (Dreissena polymorpha
Pallas, 1771) after 96 hours and 30 days. We found that both
chemicals altered the respiration process; however CYP was
determined to be more toxic regarding this particular
biological measurement.

Golden jackal (Canis aureus Linnaeus, 1758) and Red fox (Vulpes vulpes Linnaeus, 1758) population dynamics in Sarnena Sredna Gora Mts., Bulgaria based on hunting statistics
2020
Abstract. Golden jackal (Canis
aureus Linnaeus, 1758) and Red fox (Vulpes
vulpes Linnaeus, 1758) are the most common
medium-sized canid species in Bulgaria. Annual harvest hunting
data base for 2009-2019 was used as a method for assessing
changes in their population trends. The study area covers
approximately 100,000 ha comprising the areas of State
Forestry Stara Zagora, State Forestry Kazanlak, State Forestry
Maglizh and State Forestry Chirpan (Bulgaria). The hunting bag
data for jackals and foxes varied considerably during the
study period, ranging from 340 to 899 specimens for the
jackals, and from 143 to 299 for the foxes, respectively. It
can be concluded that the dynamics in the number of the Golden
jackal and the Red fox in the region of Sarnena Sredna Gora
Mts. and its adjacent territories was of different intensity
over the years and proceeded independently.

The effect of pingers on cetaceans bycatch and target catch in the turbot gillnets in Bulgarian Black Sea
2019
Abstract.
The present study is the first experiment to determine
whether acoustic deterrent devices (pingers) reduce cetaceans’
bycatch in the turbot gillnets and catch rates of the target
fish in the Bulgarian Black Sea territorial waters. During the
study period 2017–2019, 12.4 km of turbot gillnets were
included in the experiment. They were equipped with 10 kHz
Porpoise Pingers “Future Oceans”. Observations were carried
out on regular bases on active (with pingers) and on control
nets (without pingers). The results showed that the pingers
used were very effective in reducing cetaceans bycatch in
turbot gillnets without affecting the target catch.

terrarium was observed during copulation.
Preliminary data on the defensive behavior and vocalization of the Lesser blind mole rat, Nannospalax leucodon (Nordmann, 1840)
2019
Abstract. The
defensive behavior of two individuals of the Lesser blind mole
rat, Nannospalax
(superspecies) leucodon
(Nordmann, 1840), was investigated. A characteristic defensive
posture and two types of vocalization were recorded: teeth
grinding and grunting, expressed by consecutive series of
complex harsh calls, consisting of sequences of single very
short (1.7 – 2.6 ms) phases (with maximum energy at about 9.8
KHz), accompanied by strong noise component. More research is
needed to reveal the full vocal repertoire and behavioral
characteristics of the species.
The Eurasian Collared Dove (Streptopelia decaocto Frivaldszky, 1838) – a subrecent invasive species of the avifauna of Bulgaria (subfossil records)
2019
Abstract. Although
the
Collared Dove appeared in Bulgaria at 17-18th century, the
subfossil record of the species in the country is rather
scant. Only five Late Holocene sites contain bone remains (88
bones of 9 individuals), but all of them remained imprecisely
dated. Some of the sites could be of older (possibly: Early
Medieval Ages) age. All sites are situated in the NE Bulgaria
and represent former feeding places of Eagle owls (Bubo
bubo).

Lipid accumulation in Cyprinus carpio (Linnaeus, 1785) liver induced by thiamethoxam
2019
Abstract. The
aim
of the present study is to investigate the effects of a
thiamethoxam based insecticide on the expression of lipid
droplets in Common Carp, Cyprinus
Carpio (Linnaeus, 1785) liver. The selected
concentrations of the test pesticide were 6.6 mg/L, 10 mg/L
and 20 mg/L under laboratory conditions for an acute period of
96 h. The Sudan III staining method was applied for detection
of fatty degeneration in the fish hepatocytes. Overall, we
found that the fat storage in the liver cells increased
proportionally with the increased pesticide concentrations.
The results demonstrated fat accumulation in the fish liver
which in addition, could be used as an easy to perform and
relatively inexpensive biological tool for studying the
effects of pesticide contamination on fish.
Research on nesting birds on the territory of Kaliakra Wind Farm
2019
Abstract. The
study
presents data about the status of the nesting ornithofauna in
the region of Kaliakra wind farm (Kaliakra Cape, northeast
Bulgaria). The data shows the number and the density of the
birds observed in this region in 2005, before the construction
of the wind farm, and in 2009 after it’s commissioning.
Transect method was applied to establish the species
composition, numbers and density of the nesting birds. A total
amount of 24 nesting species was established. In 2005 the
recorded nesting bird species were 17, and in 2009 - 20.
Although the number of nesting species in 2009 is slightly
higher as compared to 2005, they were established in lower
numbers and density. In May the density was lower compared to
this in April. The data collected in May show about the same
density for the two compared years.

L.) under ex situ conditions. For this purpose we used Sudan
III staining which could be suggested as fast and low-cost
histochemical biomarker for pesticide contamination effects.
Heavy metals in bones from Harbour Porpoises Phocoena phocoena from the Western Black Sea Coast
2019
Abstract. During
the
last few years, the Western Black Sea coast has documented
increase in the number of stranded marine mammals,
particularly the harbour porpoise (Phocoena
phocoena). This species is a subject to threats such
as exposure to contaminants, fishery by-catch and introduced
new marine species. The aim of this study was to analyse
spatial and age trends in bone metal concentration in harbour
porpoises from the Western Black Sea Coast. Selected heavy
metals (Cu, Pb, Zn, Cd and Ni) were measured in bones of 33
harbour porpoises stranded along the Bulgarian Black Sea Coast
from 2017. Spatially, we found higher metal levels in the
harbour porpoises stranded in the Northern region compared
with those from Southern region. The effect of aging was
evident only for Zn content – the levels were higher in
juveniles than in adults. The obtained results suggested that
heavy metal contamination represent an important threat
encountered by harbour porpoises.

Cetacean mortality along the Bulgarian Black Sea Coast during 2017
2018
Abstract. The
present
study provides information on the stranding of cetaceans along
the Bulgarian Black Sea Coast during 2017. Observations were
made trough covering transects along the Bulgarian Black Sea
Coast. A total of 198 cetaceans of three species were found -
Harbor Porpoise (Phocoena
phocoena), Bottlenose Dolphin (Tursiops
truncatus), and Common Dolphin (Delphinus
delphis). The most numerous were the harbor porpoise
- 48% followed by the bottlenose dolphin - 15% and common
dolphin - 8%. The most significant number of strandings was
observed during July and August (54% of all cases). Cetacean
strandings events were relatively highly concentrated in the

Characteristics of the hunting behavior of the Red-footed Falcon (Falco vespertinus) in South-Eastern Bulgaria
2018
Abstract. Hunting
behavior was studied in a small breeding population of
Red-footed Falcons in SE-Bulgaria and in a transitory migrants
of the same species. A total of seven types of hunting
strategies were performed by the Red-footed Falcons which can
be rapidly switched from one to another in relation to the
available type of prey, the speed and direction of the wind.
It was recorded that the hovering series were longer in calm
weather (wind speed < 2 m/s) and in strong winds (over 5
m/s) than in moderate winds (2 – 5 m/s). Difference was found
in the mean length of the hovering series between the
migrating and local breeding Red-footed Falcons. The hunting
success of the finished attacks of the Red-footed Falcons was
in overall 59.6 %.

First attempt to understand the effect of pingers on static fishing gear in Bulgarian Black Sea coast
2016
Abstract. Acoustic
deterrent
devices (pingers) were used on static fishing gear called
dalyans in an attempt to reduce bycatch of small cetaceans
and/or to reduce depredation in the Bulgarian Black Sea coast.
Between April and July 2015 dalyans were equipped with harbour
porpoise pingers in the northern part of the coast. Observations
were carried out on regular bases on active (with pingers) and
on control dalyans (without pingers). The preliminary results
were positive in reducing damages on fishing gear.
Newly registered tracks of Raccoon dogs (Nyctereutes procyonoides) indicate the presence of resident population in the region of Bolata dere (NE Bulgaria)
2016
Abstract. The Raccoon
dog
(Nyctereutes procyonoides Gray, 1834) is an invasive species
which was first recorded for the Bulgarian fauna in 1968. To
date, data concerning the distribution of the species in
Bulgaria are rather scarce and often provided by non specialists
(mostly local fishermen and hunters). The present note includes
information concerning the presence of Raccoon dogs in the
region of Bolata dere (NE Bulgaria). Faeces and footprints were
found in the springs of 2014 and 2015. Apparently, the predators
are resident inhabitants of the site, so that particular
population could be used for field surveys on the biology of the
Raccoon dogs in Bulgaria.

The first report of Japanese oak silkmoth Antheraea yamamai (Guérin-Méneville, 1861) (Lepidoptera: Saturniidae) in Montenegro
2015
Abstract. Japanese oak
silkmoth Antheraea yamamai (Guérin-Méneville, 1861) is
reported here for first time in the scientific literature from
Montenegro (Republic of Crna Gora). In two localities, not far
away each other, moths were collected at light. We report this
species from Serbia as well. All collected specimens are
males.
Biology of the blind geobiont scarab beetle genus Chaetonyx Schaum, 1862 (Scarabaeidae: Orphninae) with new distribution records of Ch. robustus Schaum, 1862 from Bulgaria
2015
Abstract. Life cycle of
the orphnine scarab beetles genus Chaetonyx was recorded for
the first time based on the multiyear observations on the
populations of its type species, Ch. robustus Schaum, 1862, in
riverside habitats at Zemen Gorge region, South-Western
Bulgaria. Our observations showed that this geobiont species
is common in alluvial soils near Struma River, where it forms
large colonies. At the Zemen Gorge, its preferable habitats
are sparse riverside forests of Alnus glutinosa L. and Populus
nigra L. neighboring grass communities. Larvae, adults and
pupae were found up to 50 cm deep with most specimens
inhabiting the upper soil layer from 0 to 20 cm deep. The
highest recorded density was 89 adults and 581 larvae per 0.25
m2. Oviposition, hatching of the eggs, pupation and emergence
of the new adults occur during the summer. Eggs have been
found in surface soil layer in July and August, the pupae –
mainly in July and August. Larvae of different instars were
found in soil during all months of the study period. Adults
from the new generation first occur in the beginning of
August. In August, September and October adults from different
generations can be found together. The main part of the adults
seems to die after the reproduction period, and the common
lifespan of adults seems to be about a year only. The life
cycle of Ch. robustus in investigated habitat seems to be
perennial and includes two years as larval stage and one as
adult. Tropical Orphninae occupy a number of ecological niches
but lack colonial geobiont specialists similar to Chaetonyx.

Application of allozyme markers for screening of turbot populations along Western Black Sea coast
2015
Abstract. Data for electrophoretic pattern of 26 loci, resolved for the 8 protein systems (7-enzyme and 1-non-enzyme) assayed were used to investigate population structure of turbot along the Bulgarian and Romanian Black Sea coasts using genetic diversity measures. Seventeen loci were polymorphic in all populations and a total of 34 alleles were identified. Four types of tissue: muscle, retina, plasma and haemoglobin were analyzed. The percentage of polymorphic loci was high (65.38%) within populations. A low level of genetic differentiation among populations was detected, based on the Shannon’s information index (0.446-0.448) and the coefficient of genetic differentiation between populations (FST =0.014). The overall mean of within-population inbreeding estimate (FIS) was (-0.209) and demonstrated low level of inbreeding. The genetic distance (DNei) between the populations was low and vary between 0.003 and 0.014. Genetic distances among turbot populations were positively correlated with geographic distances (r = 0.474), but the association was not significant according to the Mantel test (p=0.651) and showed a lack of correlation between genetic distance and the geographic location of populations. Results identified one genetic stock with sufficient gene flow between all the three sites to prevent genetic differentiation from occurring. Only 1.4% of the genetic variation was observed among populations. Results revealed that adopting a single stock model and regional shared management could probably be appropriate for sustainable long-term use of turbot along western Black Sea coast. Determination of the contemporary state of the population distribution will be the prerequisite for determination of adequate measures for exploitation and protection of the existing turbot populations along western Black Sea coast.
Ground beetles (Coleoptera: Carabidae) from the region of Cape Emine (central Bulgarian Black sea coast). Part III. Spatial distribution and gradient analysis
2015
Abstract. The ground beetle fauna of the area of Cape Emine was studied. Over the period 2010 – 2012 adult carabid beetles were collected. The investigation was carried out at 13 sampling sites and pitfall traps were used. During the study altogether 12618 specimens were captured. Mathematical processing of the data by gradient analysis with methods for classification and ordination of the communities was performed. Analysis of distribution of the zoogeographical categories and life forms was done. The primary role of the humidity and vegetation as ecological factors affecting the distribution of the communities of ground beetles was proven.

Случаи на морфологична аномалия на тестиса при бялата риба (Sander lucioperca Linnaeus, 1758) в яз. Тополница (Средна гора, България)
2015
Cases of morphological testis abnormality in pikeperch (Sander lucioperca (Linnaeus, 1758) from dam-lake Topolnitsa (Sredna Gora, Bulgaria)
2015
Abstract. The paper presents cases of abnormal morphology of the pikeperch (Sander lucioperca) testis. Three of the investigated 7 males caught in the dam-lake Topolnitsa showed different morphological gonadal alterations. Possible reason for the morphological abnormalities of the male gonads in the pikeperch could be the pollution of this particularе freshwater ecosystem with different industrial wastes such as heavy metals and pesticides.
Evidences for the Lynx recovery in Bulgaria: the Lynx discovered in Western Rhodopes
2015
Abstract. On photographs taken by a camera trap in the region of Yagodina village, Western Rhodopes, (Bulgaria) the presence of the Eurasian Lynx Lynx lynx L. has been registered in the summer of 2014. This is the most reliable to date argument for the presence in Rhodope mountains of this critically endangered species in Bulgaria and for its gradual dispersal from the western mountainous border region of Bulgaria to more appropriate country habitats inland.
Soluble proteins in Messor structor (Latreille, 1798) (Hymenoptera: Formicidae) populations from Bulgaria – genetic variability and possible usage as population-genetic markers
2015
Abstract. The genetic variability of ant species determined as Messor structor (Latreille, 1798) or close to it (“M. cf. structor”) from Bulgaria has been studied using polyacrylamide gel electrophoresis analysis of five soluble protein systems (Sp-1, Sp-2, Sp-3, Sp-4 and Sp-5) corresponding to 5 loci. Four of the studied loci were found to be polymorphic. Two alleles were detected at Sp-1 and Sp-2 loci and three – at Sp-3 and Sp-5. The observed and expected heterozygosities (Ho and He) ranged from 0.0 (Yambol) to 0.140 (Topolovo) and from 0.170 (Nova Zagora) to 0.401 (Tvarditsa), respectively. The calculated mean value of inbreeding coefficient (FIS) was 0.8263 and demonstrated high level of inbreeding within populations, which correlated with a low level of observed heterozygosity compared to the expected one. The estimated mean fixation index (FST) value was 0.2746. Allele frequencies of soluble protein loci were used to estimate Nei’s (1972) genetic distance and to obtain the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and Neighbor-Joining (NJ) dendrograms, where Topolovo and Nova Zagora populations were grouped separately than other populations.
Ground beetles (Coleoptera: Carabidae) from the region of Cape Emine (central Bulgarian Black sea coast). Part II. Ecological parameters and community structure
2015
Abstract. For the first time an ecological study of the carabid fauna of the area of Cape Emine (Bulgarian Black sea coast) was conducted. Over the period 2010 – 2011 adult carabid beetles were collected. The investigation was carried out at 7 sampling sites and pitfall traps were used. During the study altogether 6245 specimens were captured. The greatest number of both species and specimens was found in the steppe-like habitat, least – in the pine (Pinus nigra J. F. Arnold) plantation. Indices for α- and β-diversity were calculated. The dominant structure of the whole carabid complex showed the presence of two eudominant, three dominant, two subdominant, eleven recedent and 85 subrecedent species. The analysis of the sex structure showed the total prevalence of males over females. Cluster analysis indicated a low percentage of taxonomic similarity between the communities, which reflected the diversity of the landscape.

Ground beetles (Coleoptera: Carabidae) from the region of Cape Emine (Central Bulgarian Black sea coast). Part I. Taxonomic and zoogeographic structure, life forms, habitat and humidity preferences
2015
Abstract. For the first time the carabid fauna of the area of Cape Emine (the middle of the Bulgarian Black sea coast) was studied. Over the period 2010 – 2012 adult carabid beetles were collected. Investigations were performed at 13 sampling sites and pitfall traps were used. During the study a total of 12618 specimens were captured. They belonged to 134 species, classified into 46 genera, 18 tribes, and 3 subfamilies. Dyschirius rufipes Dejean, 1825 and Laemostenus janthinus (Duftschmid, 1812) were reported as new species for the carabid fauna of Bulgaria. Three species were new for the fauna of the Bulgarian Black Sea coast. Fifty-four species were defined as new for the area of Cape Emine. Two endemics were found: Pterostichus merkli Frivaldszky, 1879 (Bulgarian endemic) and Cychrus semigranosus balcanicus Hopffgarten, 1881 (Balkan endemic). Species of ground beetles were characterized and classified according to their zoogeographical belonging, degree of endemism and rarity, habitat and humidity preferences; the life forms they refer to were determined.

First record of Trypanosoma infection in Mediterranean mouse (Mus macedonicus Petrov & Ružić, 1983) in Bulgaria
2014
Abstract. The study presents a Trypanosoma infection in Mediterranean mouse (Mus macedonicus Petrov & Ružić, 1983) from Plovdiv region (Bulgaria). The average established prevalence of the parasite in Mus macedonicus was 23.5 %, whereas the infection rate was lower in female (11.1%) compared to male (37.5%) individuals. All observed parasite forms are trypomastigotes, possessing the morphological characteristics of the sub-genus Herpetosoma (Stercoraria section), to which T. lewisi-like parasites belong. These features are: free flagellum, ‘‘C shape’’ of the parasite with size about 25 ± 5 μm, clear visible undulating membrane, subterminal kinetoplast with oval shape, anterior located nucleus. These morphological characteristics and the absence of infection in the other investigated rodents, hosting other Trypanosoma species, allow us to provide evidence-based assumption that the registered parasite is Trypanosoma musculi. Further studies with molecular methods are required to confirm the registered species.

Chaetonyx robustus (Scarabaeidae: Orphninae) – new natural host of Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae)
2014
Abstract. Heterorhabditis bacteriophora Poinar, 1976 was isolated from single larva of Chaetonyx robustus Schaum, 1862 (Scarabaeidae: Orphninae) from soil of a riverside habitat near town of Zemen, SW Bulgaria. Insects from the subfamily Orphninae are reported for the first time as natural hosts of heterorhabditids. In laboratory conditions larvae of C. robustus exhibited a low susceptibility to nematodes, which probably results from adaptation to avoid nematode invasion, arising from continuous coexistence in natural habitats.
Notes on autumn-winter stomach contents of the Stone Marten (Martes foina) in the Balkan Mountains, Central Bulgaria
2014
Abstract. We studied autumn-winter food (November-February, 1997-2003) of the Stone Marten in the Balkan Mountains, Central Bulgaria. A total of 26 stomachs (18 of males and eight of females) were examined, of which contents was expressed as the number of occurrence and relative frequency of occurrence. The result clearly showed that rodents are primary prey for the Stone Marten. Birds and insects were the following categories consumed. The edible dormouse was detected as a prey for the first time in Bulgaria. Besides, wild ungulates and domestic animals were occasionally scavenged, while neither fruits nor artificial materials were detected in the marten stomachs. Thus, our study showed that the Stone Marten in the Balkan Mountains tended to be more carnivorous in winter.

New localities
of Eastern Montpellier Snake – Malpolon insignitus
(Geoffroy Saint-Hilaire, 1827) from Southwestern Bulgaria
Abstract. The current report presents three new localities of
the Eastern Montpellier Snake in Bulgaria. Two of them are
situated along the valley of Mesta River whereas the third one
is on the slopes of Belasitsa Mountain. The localities along
Mesta River are of great interest, because they represent the
valley as natural corridor for penetration and distribution of
mediteranean species in Bulgaria. Two of the localities arouse
interest because of their high altitude.

Development
of Steinernema feltiae (Rhabditida: Steinernematidae) in
larvae of Chaetonyx robustus (Coleoptera: Orphnidae)
2012
ZooNotes 36: 1-4 Denis
Gradinarov, Yana Petrova
Abstract. Steinernema feltiae (Filipjev, 1934) infects
and reproduces in larvae of Chaetonyx robustus Schaum,
1862 (Coleoptera: Orphnidae), isolated from soil of the same
habitat. Insects of the family Orphnidae are reported for the
first time as hosts of entomopathogenic nematodes. Lack of
establishment of natural infected larvae may be due to the
lower susceptibility of C. robustus to nematode
invasion and random factors related to the spatial
distribution of infective juveniles in soil.

ZooNotes 34: 1-4 Denis Gradinarov
Abstract. Invaded with entomopathogenic nematode S. feltiae
(Filipjev, 1934) larva from family Asilidae was found in an
alluvial soil of riverside forest in the region of Zemen
Gorge, SW Bulgaria. It is the first record of Asilidae as
natural hosts of S. feltiae. It seems that insects from the
family Asilidae are generally among the suitable hosts of the
genus Steinernema Travassos, 1927. Members of Asilidae are
important predators in the soil, and their susceptibility to
nematode invasion must be considered when assessing the impact
of entomopathogenic nematodes on beneficial soil insects.
The Bulgarian
Odonata database – current status, organisation and a case
study new entries
2012
ZooNotes 33: 1-25 Yordan Kutsarov, Dimitar Bechev,
Rosen Kostadinov, Milen Marinov
Abstract. Bulgarian Odonata database is analysed for the
period of the last 10 years. All new entries are summarised in
individual species graphs representing the trends in data
compilations. Special attention is paid on the role of
communities in this process with a single study case which is
evident of how a small contribution could elucidate important
new information on some underexplored areas. It is concluded
that for the past 10 years mountain areas and large Bulgarian
rivers have been understudied. These should be the priority
target areas in the investigations undertaken in near future.

2011
ZooNotes 26: 1-4 Elena Tasheva - Terzieva, Maria
Yovkova, Anelia Pencheva
Abstract. Idiopterus nephrelepidis (Hemiptera: Aphididae) is
reported for the first time in Bulgaria on ornamental ferns in
four greenhouses in Sofia and Varna. Dense colonies
of apterous viviparous females and larvae were observed. The
established host plants are Nephrolepis exaltata, Asplenium
nidus and Pteris cretica. Infested ferns exhibit
leaf deformation. The aphids were reared in laboratory
conditions for four months. A morphometric study of apterae
was carried out. Taking into account the presence of
host plants of I. nephrelepidis in Bulgaria which are native
to the local flora and the reports of the aphid from the
Balkan area, it may spread in the country outdoors.

A
contribution to the knowledge of the trophic spectrum of
the Slow Worm (Anguis fragilis L., 1758) (Reptilia:
Anguidae) from Bulgaria
2010
ZooNotes 9: 1-4 Ivelin Mollov
Abstract. During our study we identified 23 prey items in 12
prey categories in the trophic spectrum of Anguis fragilis with
average
number of prey items per stomach 2.87. The most important prey
components are snails and slugs (Gastropoda) with 39.14% and
beetles (Coleoptera) with 21.72%. The estimated trophic niche
breadth is very high – 19.46. The Slow Worm forages primarily
at dawn or twilight, and the feeding is most intensive in the
summer season. It can be considered “swallowing” predator and
a “polyphage” to some extend, capturing only slowly moving
prey.
