Nature guide snakes and other reptiles and amphibians

Origin of amphibians pdf

The vertebrate fauna in Cantabria presents a wide diversity thanks to the variety of ecological niches existing in the region and its geographical position, equidistant between the Mediterranean world of the southern peninsular and the nearby world of Atlantic Europe.

In relation to conservation, amphibian populations in Cantabria, like those around the world, are suffering a marked decline mainly due to habitat loss, disease and climate change.[5][6][7] The amphibian populations of Cantabria, as well as those around the world, are suffering a marked decline mainly due to habitat loss, disease and climate change.

Anurans, commonly known as frogs and toads, are characterized (in their adult phase) by their compact body, lacking tails and possessing highly developed hind legs adapted for jumping. Five families are represented in Cantabria, grouping ten species.

L: 8-13 cm. Body covered with wart-like protuberances. The color of its skin varies between a wide range of brownish, grayish and greenish tones. Its eyes are orange. It presents a marked sexual dimorphism, females are much larger than males.

Anatomy of amphibians

The title of Luis Alza's doctoral thesis was "HISTORIA DEMOGRÁFICA Y ESTRUCTURA METAPOBLACIONAL DE UN ESPECIALISTA ANDINO DE RÍOS, EL PATO DE LAS TORRENTES (Merganetta armata)"/ "DEMOGRAPHIC HISTORY AND METAPOPULATION STRUCTURE OF AN ANDEAN RIVER SPECIALIST THE TORRENT DUCK (Merganetta armata)".

The workshop seeks to promote a regional initiative for the conservation of this coastal wetland chain.  The main objective of the workshop is to develop an Action Plan for the conservation of coastal wetlands and shorebirds on the arid Pacific coast of South America and to identify stakeholders for its implementation. The initiative would support the implementation of International Conventions, such as the Convention on Biological Diversity (CBD), Ramsar Convention (Wetlands), Convention on Migratory Species (CMS), Combating Desertification (UNCCD) and the Convention on Combating and Adapting to Climate Change (UNFCCC) in the respective countries. The workshop was organized by the Manfred Hermsen Stiftung Foundation; the Universities of La Serena and Playa Ancha of Chile and the Neotropical Wetlands Training Center of Chile.

DiagnósticoDiagnóstico (género): ver Cunha & Nascimenta 1983 (en portugués)Diagnóstico (género): Las especies de Oxyrhopus comparten una escama cloacal indivisa, subcaudales emparejadas, una fórmula temporal de 1+2 o 2+3, 7-10 infralabiales y 7-8 supralabiales, así como un hemipene profundamente bilobado, bicaliculado y bicapitado, presentando también espinas laterales agrandadas y bien desarrolladas, en tres o cuatro filas, generalmente con un área desnuda en la región lateral de cada lóbulo (Peters & Orejas-Miranda 1970, Zaher 1999); estas características, sin embargo, no son exclusivas de Oxyrhopus, y el género permanece sin un diagnóstico morfológico fiable (Gonzales et al. 2020).Diagnosis (digitalis): ver Cunha & Nascimenta 1983: 14 (en portugués)
