Biologia Reproductiva De Polychrus Acutirrostris
FACENA, Vol. 21, pp. 3-27, 2005 3 BIOLOGIA REPRODUCTIVA Y DESARROLLO DEL ESQUELETO DE POLYCHRUS ACUTIROSTRIS (IGUANIA, POLYCHROTIDAE) Blanca B. ALVAREZ(1); M.L. LIONS(1) y C. CALAMANTE(1) RESUMEN: Se describe el desarrollo del esqueleto craneal y poscraneal del Polychrus acutirostris procedente de una población del nordeste de la provincia de Formosa, (Argentina.) y se comparan con Liolaemus scapularis, L. quilmes y Tropidurus etheridgei del norte de Argentina. Las observaciones se basaron en 16 embriones y un recién nacido. Entre los rasgos más interesantes del desarrollo del condrocráneo y osteocráneo se encuentra la ausencia de taenia marginalis sobre la fenestra epióptica y la fusión de las fenestras proótica y metóptica, reducción de los cartílagos orbito- temporales y osificación temprana del pterigoides. Entre los eventos poscraneales se destaca la osifi- cación temprana de las clavículas, osificación asincrónica de los elementos de ambas cinturas y sin- crónica de los elementos estilopodiales y zeugopodiales en ambos miembros. Adicionalmente se compararon datos de la biología reproductiva de Polychrus acutirostris de las po- blaciones de Formosa (Argentina) con las del Cerrado (Brasil). ABSTRACT: The fully chondrocranium development and the cranial and postcranial sequences of ossi- fication of Polychrus acutirostris (Polychrotidae) were described. The observations were based on sixteen embryos and one hatched specimen from the northeast of Argentina. Among the characters of chondrocranium and osteocranium development, the lost of taenia margin- alis on the epioptica fenestra, the fusion of prootica and metoptica fenestra, reduction of orbitotempo- rales cartilages and the early ossification of the pterygoid are remarkable. Among postcranial events we stress the early ossification of clavicles, asincronic ossification of pectoral and pelvic girdles ele- ments and sincronic ossification of stylopodial and zeugopodial elements in both forelimb and hind limb. -
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. -

Estado del conocimiento Alejandra HERNANDO1 y Blanca ALVAREZ1 Abstract: CHROMOSONIC STUDIES ON SAURIA AND ANPHISBENIDS. Morphological characters are traditionally involbed in taxonomic studies of Squamata. However, cytogenetic information from chromosome number, size and shape to molecular level can be an important contribution for systematics and phylogenetic analysis. In this paper, we summarize the karyotypic data available for lizards and amphisbaenians species distributed in the Argentinean littoral region. Chromosome formulae, banding patterns when exist and a brief remark about genera or families cytogenetic features are given. Key words: Lizards - Amphisbaenians - Cytogenetics - Karyotypes - Chromosome banding - Argentinean littoral region. Palabras clave: Saurios - Anfisbénidos - Citogenética - Cariotipos - Bandeos cromosomas - Litoral fluvial argentino Iintroducción Los caracteres cromosómicos pueden brindar información no evidente a nivel fenético (como en el caso de las especies crípticas) y, dependiendo del nivel de análisis, son herramientas importantes para resolver problemas sistemáticos. Además, como los caracteres cariológicos, morfológicos, inmunológicos, isoenzimáticos no evolucionan de manera paralela las comparaciones del grado de diversificación de los cariotipos con el grado de divergencia de otros caracteres son útiles para inferir relaciones filogenéticas (Peccinini- Seale 1981). Los cromosomas pueden analizarse teniendo en cuenta la forma, tamaño, número y comporta- miento durante la meiosis y mitosis. Con el desarrollo de las técnicas de coloración diferencial y de hibridación in situ es posible identificar los cromosomas por sus patrones característicos de bandas. -
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!

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. Iguania, bite force, ontogenetic change, foraging strategy, stomach contents, food niche, feeding behavior, Marañón river Citation: Beuttner A, Koch C. 2019.
