Lora Snake (Philodryas Olfersii) Venom
Revista da Sociedade Brasileira de Medicina Tropical 39(2):193-197, mar-abr, 2006 ARTIGO/ARTICLE Experimental ophitoxemia produced by the opisthoglyphous lora snake (Philodryas olfersii) venom Ofitoxemia experimental produzida pelo veneno da serpente opistoglifa lora (Philodryas olfersii) Alexis Rodríguez-Acosta1, Karel Lemoine1, Luis Navarrete1, María E. Girón1 and Irma Aguilar1 ABSTRACT Several colubrid snakes produce venomous oral secretions. In this work, the venom collected from Venezuelan opisthoglyphous (rear-fanged) Philodryas olfersii snake was studied. Different proteins were present in its venom and they were characterized by 20% SDS-PAGE protein electrophoresis. The secretion exhibited proteolytic (gelatinase) activity, which was partially purified on a chromatography ionic exchange mono Q2 column. Additionally, the haemorrhagic activity of Philodryas olfersii venom on chicken embryos, mouse skin and peritoneum was demonstrated. Neurotoxic symptoms were demonstrated in mice inoculated with Philodryas olfersii venom. In conclusion, Philodryas olfersii venom showed proteolytic, haemorrhagic, and neurotoxic activities, thus increasing the interest in the high toxic action of Philodryas venom. Key-words: Colubridae. Haemorrhage. Neurotoxic. Philodryas olfersii. Proteolytic activity. Venom. RESUMO Várias serpentes da família Colubridae produzem secreções orais venenosas. Neste trabalho, foi estudado o veneno coletado da presa posterior da serpente opistóglifa venezuelana Philodryas olfersii. Deferentes proteínas estavam presentes no veneno, sendo caracterizadas pela eletroforese de proteínas (SDS-PAGE) a 20%. A secreção mostrou atividade proteolítica (gelatinase) a qual foi parcialmente purificada em uma coluna de intercâmbio iônico (mono Q2). Adicionalmente, a atividade hemorrágica do veneno de Philodryas olfersii foi demonstrada em embriões de galinha, pele e peritônio de rato. Os sintomas neurológicos foram demonstrados em camundongos inoculados com veneno de Philodryas olfersii. -
Abstract Book
Welcome to the Ornithological Congress of the Americas! Puerto Iguazú, Misiones, Argentina, from 8–11 August, 2017 Puerto Iguazú is located in the heart of the interior Atlantic Forest and is the portal to the Iguazú Falls, one of the world’s Seven Natural Wonders and a UNESCO World Heritage Site. The area surrounding Puerto Iguazú, the province of Misiones and neighboring regions of Paraguay and Brazil offers many scenic attractions and natural areas such as Iguazú National Park, and provides unique opportunities for birdwatching. Over 500 species have been recorded, including many Atlantic Forest endemics like the Blue Manakin (Chiroxiphia caudata), the emblem of our congress. This is the first meeting collaboratively organized by the Association of Field Ornithologists, Sociedade Brasileira de Ornitologia and Aves Argentinas, and promises to be an outstanding professional experience for both students and researchers. The congress will feature workshops, symposia, over 400 scientific presentations, 7 internationally renowned plenary speakers, and a celebration of 100 years of Aves Argentinas! Enjoy the book of abstracts!

The characteristics of the eggs, incubation time, and hatching are still unknown. This work describes for the first time the oviposition of 16 eggs by a female in captivity at Zoológico Nacional in Chile. After an incubation period of 59 days, seven neonates were born. We recorded data of biometry and ecdysis of these neonates for 9 months. In addition, a review about parameters of egg incubation and hatching for Philodryas species is provided.

Reserva Natural Laguna Blanca, Departmento San Pedro
Russian Journal of Herpetology Vol. 23, No. 1, 2016, pp. 25 – 34 RESERVA NATURAL LAGUNA BLANCA, DEPARTAMENTO SAN PEDRO: PARAGUAY’S FIRST IMPORTANT AREA FOR THE CONSERVATION OF AMPHIBIANS AND REPTILES? Paul Smith,1,2 Karina Atkinson,2 Jean-Paul Brouard,2 Helen Pheasey2 Submitted December 30, 2014. Geographical sampling bias and restricted search methodologies have resulted in the distribution of Paraguayan reptiles and amphibians being patchily known. Available data is almost entirely based on brief collecting trips and rapid ecological inventories, often several decades apart, which inevitably struggle to detect more inconspicuous species and patterns of abundance. This has led to a deficit in our knowledge of the true distribution and abun- dance of Paraguayan reptiles and amphibians. The establishment of the NGO Para La Tierra at Reserva Natural Laguna Blanca (RNLB), Depto. San Pedro, Paraguay allowed the first modern sustained, multi-method inventory of Paraguayan reptiles and amphibians to be performed at a single site. Despite the small size of the reserve (804 ha), a total of 57 reptiles (12 of national conservation concern) and 32 amphibians (one of national conserva- tion concern) were collected during five years of random sampling, qualifying RNLB as the most biodiverse re- serve for reptiles and amphibians in the country. Six species occurring at RNLB have been found at no other Para- guayan locality. Legal protection for this private reserve expired in January 2015 and the conservation implica- tions of the inventory results are discussed. It is proposed that the long term legal protection of the reserve be con- sidered a national conservation priority and that the diversity of the herpetofauna be recognized with the designa- tion of RNLB as Paraguay’s first Important Area for the Conservation of Amphibians and Reptiles. -

E-mail: luisfelipe. lopez@biologia. ulpgc. es Abstract: The description of a new species ofthe genus Uromastyx is proposed on the basis oftwo specimens from the Adrar Souttouf in Western Sahara. This taxon differs greatly from U. acanthinura on account its larger size, the much larger number of scales, the arrangement of tubercules on its upper thighs, the different habitus and colouring. These morphological features mean it closely resembles U. aegyptia. The existence of a relictual U. aegyptia-group throughout the Sahara is suggested. In addition, the morphological variations in Spiny-tailed agamas (or Mastigures) ofthe Uromastyx acanthinura group in the west ofthe Sahara are briefl y analysed. This produces evidence for the existence of a species proper to Western Sahara and surrounding areas, Uromastyx jlavifasciata, represented by two subspecies: U. f jlavifasciata in the north and U. f obscura subsp. nov. in the south. The latter new form is characterised by uniformly black colouring, even in active individuals. This work also demonstrates that Uromastyx acanthinura werneri does not penetrate Western Sahara and that its distribution is parapatric with that of U. -
