Newly registered tracks of Raccoon dogs (Nyctereutes procyonoides) indicate the presence of resident population in the region of Bolata dere (NE Bulgaria)

2016     ZooNotes 90: 1-3:  Nikolay Natchev


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.

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     ZooNotes 81: 1-14: Denis Gradinarov, Yana Petrova, Elena Tasheva-Terzieva, Andrey Frolov


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     ZooNotes 79: 1-15: Venelin Nikolov, Petya Ivanova, Nina Dzhembekova, Marina Panayotova, Violin Raykov, Ivan Dobrovolov

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.

2015     ZooNotes 72: 1-9: Ivan Stoyanov, Evgenia Ivanova, Penka Vasileva, Teodora Staykova

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     ZooNotes 71: 1-12: Teodora Teofilova

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     ZooNotes 68: 1-18: Teodora Teofilova, Emilia Markova, Nikolai Kodzhabashev

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     ZooNotes 64: 1-6: Vesela Mitkovska, Tsenka Chassovnikarova, Hristo Dimitrov

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     ZooNotes 57: 1-4: Denis Gradinarov

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     ZooNotes 56: 1-6: Masumi Hisano, Evgeni Raichev, Stanislava Peeva, Dian  Georgiev, Hiroshi Tsunoda, Ryuichi Masuda, Yayoi Kaneko

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.

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.

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.
