Many societies around the world use these animals for a variety of purposes, such as food and medicinal use. Within this context, we examined hunting activities involving the herpetofauna in montane, dryland, and coastal areas of Ceará state, northeastern Brazil. We analyzed the diversity of species captured, how each species was used, the capture techniques employed, and the conservation implications of these activities on populations of those animals. We documented six hunting techniques and identified twenty-six species utilized (including five species threatened with extinction) belonging to 15 families as important for food (21 spp.), folk medicine (18 spp.), magic-religious purposes (1 sp.), and other uses (9 spp.). although the highest species richness utilized was observed in the montane region, the herpetofauna was more intensively utilized in the drylands. these results reflect biological, historical, cultural, and social-economic issues.

The struggle, from emergence to end, lasted just over 1.5 minutes (90 seconds), 68 seconds of which were recorded, and can be viewed online at: http://www. californiaherps.com/movies/pskiltonianusfightwacr517.mp4. We remained in the vicinity for another 30 minutes. At 1115 h, the male, which had returned to the rock, stuck its head out from under the rock’s edge and sat, looking around, until we departed. The weather during this encounter was sunny and warm, with 10% high cloud cover and a light (2–3 kph) breeze from the south. The air temperature 2 cm above the soil surface ranged from 28 to 33°C, and the temperature under the rock from which the pair of P. skiltonianus originally emerged was 17.6°C. Although male combat has not been described for P. skilto- nianus, it is well known in several other species of North Ameri- can skinks, including P. fasciatus and P. laticeps (Fitch 1951.

Analysis of diet composition and morphological characters of the little-known Peruvian bush anole Polychrus peruvianus (Noble, 1924) in a northern Peruvian dry forest 1Antonia Beuttner and 2,*Claudia Koch 1Universität Tübingen, Geschwister-Scholl-Platz, 72074 Tübingen, GERMANY 2Zoologisches Forschungsmuseum Alexander Koenig (ZFMK), Adenauerallee 160, 53113 Bonn, GERMANY Abstract.—Analyses of diet composition are an important element of studies focusing on biological diversity, ecology, and behavior of animals. Polychrus peruvianus was found to be a quite abundant lizard species in the northern Peruvian dry forest. However, our knowledge of the ecology of this species remains limited. Herein, we analyze the species dietary composition and the morphological features that may be related to the feeding behavior. Our results show that P. peruvianus is a semi-herbivorous food generalist, which also consumes faunistic prey. All age groups prefer mobile prey as sit-and-wait predators. However, during ontogenesis, plant material becomes the main component in the diet of adult specimens. Keywords.

The lack of information on the occurrence of species in a region limits the understanding of the composition and structure of the local community and, consequently, restricts the proposition of effective measures for species conservation. In this study, we researched the reptiles in the Duas Bocas Biological Reserve (DBBR), Espírito Santo, southeastern Brazil. We analyzed the parameters of the local community, such as richness, composition, and abundance of species. We conducted samplings from August 2017 to January 2019, through active search. We performed the samplings in nine standard plots of 250 meters in length. All individuals located in the plots or occasionally on the trails were registered.

We also summarized data on lizard faunas for nine other well-studied areas in Amazonia to make pairwise comparisons among sites. The Biogeographic Similarity Coefficient for each pair of sites was calculated and plotted against the geographic distance between the sites. A Parsimony Analysis of Endemicity was performed comparing all sites. A total of 114 species has been recorded in the four studied sites, of which 45 are lizards, three amphisbaenians, and 66 snakes. The two sites between the Xingu and Madeira rivers were the poorest in number of species, those in western Amazonia, between the Madeira and Juruá Rivers, were the richest. Biogeographic analyses corroborated the existence of a well-defined separation between a western and an eastern lizard fauna. The western fauna contains two groups, which occupy respectively the areas of endemism known as Napo (west) and Inambari (southwest). Relationships among these western localities varied, except between the two northernmost localities, Iquitos and Santa Cecilia, which grouped together in all five area cladograms obtained. No variation existed in the area cladogram between eastern Amazonia sites. The easternmost localities grouped with Guianan localities, and they all grouped with localities more to the west, south of the Amazon River.

  • For Specific Identification of Lachesis Acrochorda Venom
    The Journal of Venomous Animals and Toxins including Tropical Diseases ISSN 1678-9199 | 2012 | volume 18 | issue 2 | pages 173-179 Development of a sensitive enzyme immunoassay (ELISA) for specific ER P identification of Lachesis acrochorda venom A P Núñez Rangel V (1, 2), Fernández Culma M (1), Rey-Suárez P (1), Pereañez JA (1, 3) RIGINAL O (1) Program of Ophidism and Scorpionism, University of Antioquia, Medellin, Colombia; (2) School of Microbiology, University of Antioquia, Medellin, Colombia; (3) School of Pharmaceutical Chemistry, University of Antioquia, Medellin, Colombia. Abstract: The snake genus Lachesis provokes 2 to 3% of snakebites in Colombia every year. Two Lachesis species, L. acrochorda and L. muta, share habitats with snakes from another genus, namely Bothrops asper and B. atrox. Lachesis venom causes systemic and local effects such as swelling, hemorrhaging, myonecrosis, hemostatic disorders and nephrotoxic symptoms similar to those induced by Bothrops, Portidium and Bothriechis bites. Bothrops antivenoms neutralize a variety of Lachesis venom toxins. However, these products are unable to avoid coagulation problems provoked by Lachesis snakebites. Thus, it is important to ascertain whether the envenomation was caused by a Bothrops or Lachesis snake. The present study found enzyme linked immunosorbent assay (ELISA) efficient for detecting Lachesis acrochorda venom in a concentration range of 3.9 to 1000 ng/mL, which did not show a cross-reaction with Bothrops, Portidium, Botriechis and Crotalus venoms. Furthermore, one fraction of L. acrochorda venom that did not show cross- reactivity with B. asper venom was isolated using the same ELISA antibodies; some of its proteins were identified including one Gal-specific lectin and one metalloproteinase.
