62 New Records of Paracapillaria sonsinoi in Timber Rattlesnake A New Host and Geographic Record for Paracapillaria sonsinoi (Nematoda: Capillariidae) from Timber Rattlesnake, Crotalus horridus (Serpentes: Crotalidae) from Oklahoma Chris T. McAllister Science and Mathematics Division, Eastern Oklahoma State College, Idabel, OK 74745 Charles R. Bursey Department of Biology, Pennsylvania State University, Shenango Valley Campus, Sharon, PA 16146 Abstract: Compared to other members of the genus Crotalus, little is known about the helminth parasites of the timber rattlesnake, Crotalus horridus. Here, we report, for the first time, a species of capillariid nematode from C. horridus and from Oklahoma. the Catskill Mountains (New York), Louisiana, North Carolina, and Virginia (Fantham and Introduction Porter 1954; Solomon 1974; Bowman 1984; Ernst and Ernst 2006; Davis et al. 2016). More The timber rattlesnake, Crotalus horridus L., recently, McAllister et al. (2018) reported an 1758, is a heavily-bodied venomous snake that unknown species of capillariid (egg) from C. ranges from southcentral New Hampshire and horridus from Oklahoma. However, no adult the Lake Champlain region south to northern helminths have been reported from C. horridus Florida and west to southeastern Minnesota from Oklahoma. Here, we document a new and central Texas (Powell et al. 2016).

In particular, Pachmarhi Biosphere Reserve (PBR) regions (Districts Hoshangabad, Betul and Chindwara) of MP comprises a vast range of reptiles, especially herpetofauna yet unexplored from the conservation point of view. Earlier inventory herpetofaunal study conducted in 2005 at MP and Chhattisgarh (CG) reported 6 snake families included 39 species. After this preliminary report, no literature existing regarding snake diversity of this region. This situation incited us to update the snake diversity of PBR regions. From 2010 to 2012, we conducted a detailed field study and recorded 31 species of 6 snake families (Boidae, Colubridae, Elapidae, Typhlopidea, Uropeltidae, and Viperidae) in Hoshanagbad District (Satpura Tiger Reserve) and PBR regions. Besides, we found the occurrence of Boiga forsteni and Coelognatus helena monticollaris (Colubridae), which was not previously reported in PBR region. Among the recorded, 9 species were Lower Risk – least concerned (LR-lc), 20 were of Lower Risk – near threatened (LR-nt), 1 is Endangered (EN) and 1 is vulnerable (VU) according to International Union for Conservation of Nature (IUCN) status.

    Herpetofaunistic Diversity of the Cres-Lošinj Archipelago (Croatian Adriatic)

    University of Sopron Roth Gyula Doctoral School of Forestry and Wildlife Management Sciences Ph.D. thesis Herpetofaunistic diversity of the Cres-Lošinj Archipelago (Croatian Adriatic) Tamás Tóth Sopron 2018 Roth Gyula Doctoral School of Forestry and Wildlife Management Sciences Nature Conservation Program Supervisors: Prof. Dr. Faragó Sándor Dr. Gál János Introduction In recent years the Croatian islands, especially those of the Cres-Lošinj Archipelago became the focus of research of herpetologists. However, in spite of a long interest encompassing more than a hundred years, numerous gaps remain in our herpetological knowledge. For this reason, the author wished to contribute to a better understanding by performing studies outlined below. Aims The first task was to map the distribution of amphibians and reptiles inhabiting the archipelago as data were lacking for several of the smaller islands and also the fauna of the bigger islands was insufficiently known. Subsequently, the faunistic information derived from the scientific literature and field surveys conducted by the author as well as available geological and paleogeological data were compared and analysed from a zoogeographic point of view. The author wished to identify regions of the islands boasting the greatest herpetofaunal diversity by creating dot maps based on collecting localities. To answer the question which snake species and which individuals are going to be a victim of the traffic snake roadkill and literature survey were used. The author also identified where are the areas where the most snakes are hit by a vehicle on Cres. By gathering road-killed snakes and comparing their locality data with published occurrences the author seeked to identify species most vulnerable to vehicular traffic and road sections posing the greatest threat to snakes on Cres Island.

Twenty­five mustelids were examined for hel­ Vytautas Mažeika*, minths: 2 pine martens (Martes martes), 4 stone martens (Mar­ tes foina), 9 American minks (Neovison vison) and 10 European Algimantas Paulauskas polecats (Mustela putorius). Nine taxa of the parasitic worms were found: trematodes Isthmiophora melis (Schrank, 1788) and Stri­ Faculty of Natural Sciences, gea strigis (Schrank, 1788) mesocercaria, cestodes Mesocestoides Vytautas Magnus University, lineatus Goeze, 1782 and Cestoda g. sp. and nematodes Eucoleus Vileikos str. 8, aerophilus (Creplin, 1839), Aonchotheca putorii (Rudolphi, 1819), LT-44404 Kaunas, Lithuania Crenosoma schachmatovae Kontrimavičius, 1969, Molineus pa­ tens (Rudolphi, 1845) and Nematoda g. sp. The biggest infection parameters were detected for flukes Isthmiophora melis and Stri­ gea strigis mesocercaria in American mink and European pole­ cat. In most cases the distribution of helminths in populations of mustelids was aggregated (s2/A > 1). Key words: mustelids, helminths, Lithuania INTRODUCTION melis (recorded under name Euparyphium me­ lis) were found. Both pine marten and Eurasian In Lithuania pine marten (Martes martes), stone badger were infected by nematodes Aonchotheca marten (Martes foina), stoat (Mustela erminea), putorii (recorded under name Capillaria putorii) least weasel (Mustela nivalis), European pole­ and Filaroides martis. Only Eurasian badger cat (Mustela putorius), American mink (Neovi­ was parasitized by cestode Mesocestoides linea­ son vison), Eurasian badger (Meles meles) and tus and nematodes Trichinella spiralis and Unci­ European otter (Lutra lutra) are found.
