Ecology of the Squirrel Treefrog (Hyla squirella) in Southern Arkansas

We conducted an ecological study of the Squirrel Treefrog, Hyla squirella near El Dorado, Union Co., Arkansas from May-Oct. 2013. We extended the known distribution by ~2 km and documented the first breeding occurring on 28 May and the first transformation of juveniles on 27 Aug. Three endoparasites were documented: Opalina sp., Nyctotherus cordiformis, and Physaloptera sp. larvae. We also provide information on endoparasites of Florida H. squirella as well as a summary of helminths of this frog

Comparative Study of Helminth Parasites of the Many-Ribbed Salamander, Eurycea multiplicata and Oklahoma Salamander, Eurycea tynerensis (Caudata: Plethodontidae), from Arkansas and Oklahoma, A

Ninety many-ribbed salamanders, Eurycea multiplicata and 135 Oklahoma salamanders, Eurycea tynerensis were collected between April 2010 and April 2014 from 14 counties of Arkansas and McCurtain County, Oklahoma (E. multiplicata only) and examined for helminth parasites. Twelve (13%) E. multiplicata were infected, including two (2%) each with Brachycoelium salamandrae, Bothriocephalus rarus, Batracholandros magnavulvaris, Cosmocercoides variabilis, and Omeia papillocauda, and one (1%) each with an oligacanthorhynchid cystacanth and Fessisentis vancleavei. Forty-one (30%) of the E. tynerensis were infected, including seven (5%) with Gorgoderina tenua, two (1%) each with Phyllodistomum solidum and cyclophyllidean tapeworm cysticerci, one (0.7%) with Cylindrotaenia americana, six (3%) with B. rarus, eight (12%) with Desmognathinema nantahalaensis, 10 (7%) with O. papillocauda, two (1%) with Amphibiocapillaria tritonipunctata and six (4%) with F. vancleavei. We document 13 new host and two new distributional records for helminths of these salamanders. In addition, a summary of the endoparasites of E. multiplicata and E. tynerensis is provided

Gastrointestinal helminths in two species of geckos, gekko vittatus, gehyra oceanica, and five species of skinks, caledoniscincus atropunctatus, Emoia cyanogaster, Emoia erronan, Emoia nigra, Emoia sanfordi (Squamata) from the republic of Vanuatu, Oceania

Two species of geckos, Gekko vittatus, Gehyra oceanica and 5 species of skinks, Caledoniscincus atropunctatus, Emoia cyanogaster, Emoia erronan, Emoia nigra, and Emoia sanfordi from the Republic of Vanuatu were examined for helminths. One species of Digenea (Mesocoelium microon), 3 species of Cestoda (Gekkotaenia novaeguineaensis, Cylindrotaenia hickmani, Ophiotaenia greeri), and 7 species of Nematoda, gravid individuals of Hedruris hanleyae, Maxvachonia chabaudi, Parapharyngodon maplestoni, Spauligodon gehyrae, Spauligodon zweifeli, juveniles assigned to the Filarioidea, and larvae of Physocephalus sp. in cysts were found. Eighteen new host records and 7 new locality records are reported. The lizards of Vanuatu are infected by generalist helminths that occur in a variety of lizards throughout Oceania. © The Helminthological Society of Washington

Vertebrate Natural History Notes from Arkansas, 2017

Because meaningful observations of natural history are not always part of larger studies, important pieces of information often are unreported. Small details, however, can fills gaps in understanding and also lead to interesting questions about ecological relationships or environmental change. We have compiled recent observations of foods, reproduction, record size, parasites, and distribution of 30 species of fishes, new records of distribution and parasites of 2 species of amphibians, and new records of distribution, parasites, reproduction and anomalies of 11 species of mammals
