Chelonian Perivitelline Membrane-Bound Sperm Detection: a New Breeding Management Tool
Zoo Biology 35: 95–103 (2016) RESEARCH ARTICLE Chelonian Perivitelline Membrane-Bound Sperm Detection: A New Breeding Management Tool Kaitlin Croyle,1,2 Paul Gibbons,3 Christine Light,3 Eric Goode,3 Barbara Durrant,1 and Thomas Jensen1* 1San Diego Zoo Institute for Conservation Research, Escondido, California 2Department of Biological Sciences, California State University San Marcos, San Marcos, California 3Turtle Conservancy, New York, New York Perivitelline membrane (PVM)-bound sperm detection has recently been incorporated into avian breeding programs to assess egg fertility, confirm successful copulation, and to evaluate male reproductive status and pair compatibility. Due to the similarities between avian and chelonian egg structure and development, and because fertility determination in chelonian eggs lacking embryonic growth is equally challenging, PVM-bound sperm detection may also be a promising tool for the reproductive management of turtles and tortoises. This study is the first to successfully demonstrate the use of PVM-bound sperm detection in chelonian eggs. Recovered membranes were stained with Hoechst 33342 and examined for sperm presence using fluorescence microscopy. Sperm were positively identified for up to 206 days post-oviposition, following storage, diapause, and/or incubation, in 52 opportunistically collected eggs representing 12 species. However, advanced microbial infection frequently hindered the ability to detect membrane-bound sperm. Fertile Centrochelys sulcata, Manouria emys,andStigmochelys pardalis eggs were used to evaluate the impact of incubation and storage on the ability to detect sperm. Storage at À20°C or in formalin were found to be the best methods for egg preservation prior to sperm detection. Additionally, sperm-derived mtDNA was isolated and PCR amplified from Astrochelys radiata, C. -
Helminth Parasites (Trematoda, Cestoda, Nematoda, Acanthocephala) of Herpetofauna from Southeastern Oklahoma: New Host and Geographic Records
125 Helminth Parasites (Trematoda, Cestoda, Nematoda, Acanthocephala) of Herpetofauna from Southeastern Oklahoma: New Host and Geographic Records Chris T. McAllister Science and Mathematics Division, Eastern Oklahoma State College, Idabel, OK 74745 Charles R. Bursey Department of Biology, Pennsylvania State University-Shenango, Sharon, PA 16146 Matthew B. Connior Life Sciences, Northwest Arkansas Community College, Bentonville, AR 72712 Abstract: Between May 2013 and September 2015, two amphibian and eight reptilian species/ subspecies were collected from Atoka (n = 1) and McCurtain (n = 31) counties, Oklahoma, and examined for helminth parasites. Twelve helminths, including a monogenean, six digeneans, a cestode, three nematodes and two acanthocephalans was found to be infecting these hosts. We document nine new host and three new distributional records for these helminths. Although we provide new records, additional surveys are needed for some of the 257 species of amphibians and reptiles of the state, particularly those in the western and panhandle regions who remain to be examined for helminths. ©2015 Oklahoma Academy of Science Introduction Methods In the last two decades, several papers from Between May 2013 and September 2015, our laboratories have appeared in the literature 11 Sequoyah slimy salamander (Plethodon that has helped increase our knowledge of sequoyah), nine Blanchard’s cricket frog the helminth parasites of Oklahoma’s diverse (Acris blanchardii), two eastern cooter herpetofauna (McAllister and Bursey 2004, (Pseudemys concinna concinna), two common 2007, 2012; McAllister et al. 1995, 2002, snapping turtle (Chelydra serpentina), two 2005, 2010, 2011, 2013, 2014a, b, c; Bonett Mississippi mud turtle (Kinosternon subrubrum et al. 2011).

Redescription, Molecular Characterisation and Taxonomic Re-Evaluation of a Unique African Monitor Lizard Haemogregarine Karyolysus Paradoxa (Dias, 1954) N
Cook et al. Parasites & Vectors (2016) 9:347 DOI 10.1186/s13071-016-1600-8 RESEARCH Open Access Redescription, molecular characterisation and taxonomic re-evaluation of a unique African monitor lizard haemogregarine Karyolysus paradoxa (Dias, 1954) n. comb. (Karyolysidae) Courtney A. Cook1*, Edward C. Netherlands1,2† and Nico J. Smit1† Abstract Background: Within the African monitor lizard family Varanidae, two haemogregarine genera have been reported. These comprise five species of Hepatozoon Miller, 1908 and a species of Haemogregarina Danilewsky, 1885. Even though other haemogregarine genera such as Hemolivia Petit, Landau, Baccam & Lainson, 1990 and Karyolysus Labbé, 1894 have been reported parasitising other lizard families, these have not been found infecting the Varanidae. The genus Karyolysus has to date been formally described and named only from lizards of the family Lacertidae and to the authors’ knowledge, this includes only nine species. Molecular characterisation using fragments of the 18S gene has only recently been completed for but two of these species. To date, three Hepatozoon species are known from southern African varanids, one of these Hepatozoon paradoxa (Dias, 1954) shares morphological characteristics alike to species of the family Karyolysidae. Thus, this study aimed to morphologically redescribe and characterise H. paradoxa molecularly, so as to determine its taxonomic placement. Methods: Specimens of Varanus albigularis albigularis Daudin, 1802 (Rock monitor) and Varanus niloticus (Linnaeus in Hasselquist, 1762) (Nile monitor) were collected from the Ndumo Game Reserve, South Africa. Upon capture animals were examined for haematophagous arthropods. Blood was collected, thin blood smears prepared, stained with Giemsa, screened and micrographs of parasites captured. Haemogregarine morphometric data were compared with the data for named haemogregarines of African varanids. -

STUDBOOK RHINOCLEMMYS Spp. Introduction by Studbook Keeper Harry Rotmans
STUDBOOK RHINOCLEMMYS spp. Introduction by studbook keeper Harry Rotmans Rhinoclemmys pulcherrima incisa (Photo F.Grünewald) Rhinoclemmys melanosterna (Photo F. Grünewald) Rhinoclemmys punctularia (Photo F. Grünewald) Introduction Recently a start has been made with a studbook for Rhinoclemmys spp. An appeal in Trionyx no. 2(3):94, a magazine of the Nederlandse Schildpadden Vereniging (NSV) (Dutch Turtle/Tortoise Society), produced several positive responses, so the minimum requirements for a new ESF-studbook were met. Because the genus Rhinoclemmys consists of several species, the new studbook will be a coordination of several registrations. The word Rhinoclemmys will be conveniently abbreviated to “R” from now on. Why this studbook? Gradually, more R. turtles are imported from Middle- and South- America. You get the impression that it is meant to become a relatively cheap alternative to protected turtle species from other parts of the world, which are illegal to trade. The clutch of eggs of the R. species are relative small compared to the greater part of the other turtle species (HOFSTRA), mostly 1 or 2 eggs. A number of R. species produces very few clutches in a year. Sooner or later this will lead to the threatening of the population in the wild. Further factors are the affection and destruction of their environment and the pet trade. R. turtles will be used as food in some places by the locals, the same situation as in Asia. Only the population of people in Asia is more dense than in Middle- and South-America, so the need for food is much higher there. Import in the future will probably not become massive, as far as we can see, because there are no farms in the countries concerned with breeding the species.
