This study deals with the distribution of the amphibians and reptiles of the Parque Natural do Douro Internacional (PNDI) in the north eastern part of Portugal. In the introduction the geological and climatical conditions of this region as well as the habitats and the herpetofaunistic studies are described. 12 amphibian and 20 reptile species were recorded. The distribution pattern of each species is shown by map within a 1 × 1 km UTM grid system. The Natural Park consists in a Planalto, a western branch of the Spanish Meseta, and is subdivided in the Douro Canyon and its tributaries. Along these rivers mesomediterranean species (Plenrodeles waltl, Alytes cistemasii, Mauremys leprosa, Tarentola mauritanien, Macroprotodon brevis) penetrate into the supramediterranean area of the Planalto. They appear there in an isolated area at the northernmost boundery of their distribution area. A mountain range between Serra da Estrela and the Central Iberian Cordillères prevent a connection of these isolates with the continuous distribution areas in Central and Southern Portugal. Hemorrhois hippocrepis and Macroprotodon brevis reach within the PNDI the northernmost points of there distribution. Finally, the human impact on the landscape (change of agricultural activities, excessive use of agricultural chemistry, water pollution, introduction of adventive species) and its influence on the distribution pattern of the amphibians and reptiles are discussed. © Laurenti-Verlag, Bielefeld.

The study deals with the distribution of the amphibians and reptiles of the southeastern Beira Alta. In the introduction the geological and climatical conditions of this region as well as the habitats and the herpetofaunistic studies are described. 14 amphibian and 23 reptile species are recorded. The distribution pattern of each species is shown by map within a 1 × 1 km UTM (Universal Transverse Mercator) grid sytem. On the planalto of the investigated area supramediterranean and eurosiberian species predominate. Along the valleys mesomediterranean elements penetrate from the southwest and from the north (river Côa) into this area. Within this area Hyla meridionalis reaches the northern-most occurrence in Portugal and Macroprotodon cucullatus the northern-most point of its southern range. The area constitutes a narrow corridor for eurosiberian species (Rana iberica, Lacerta schreiben, Anguis fragilis) creating a connection of their northwest Iberian distribution area with that of the central Iberian Cordilleres. Finally the human impact (water pollution, change of agricultural activities, reforestation) and the importance of protected areas for herpetofauna are discussed. © Laurenti-Verlag, Bielefeld.

We describe the distribution of the amphibians and reptiles of the Barroso region (northern Portugal). In the introduction the geological and climatical conditions of this region as well as the habitat types and the herpetofaunistic studies, published up to now are described. 12 amphibian and 19 reptile species are recorded. The distribution pattern of each species is shown by map using the 1×1 km squares of the UTM grid system. Within the investigated area predominate Eurosiberian species, including numerous Iberian endemits (Chioglossa lusitanica, Rana ibérica, Lacerta schreiben, Podareis bocagei, Vipera seoanei). Along the southern slopes of the area some mediterranean elements (Tarentola mauritanica, Blanus cinereus) penetrate into the area. Within the region Vipera seoanei reaches the southernmost occurrence of its total distribution range; Psammodromus hispanicus and Chalcides bedriagai their northwestern distribution limit in Portugal. The human impact on the landscape and it's influence on the distribution pattern of the amphibian and reptile species are discussed. Special sources of danger for the populations in the area are the change of agricultural activities, reforestations and the building of dams. © Laurenti-Verlag, Bielefeld,. Source


Within the forest area «Gramschatzer Wald» north of Würzburg 5 spawning sites of the agile frog were found during March/April 2010. It's the first record of Rana dalmatina for this region. © Laurenti-Verlag, Bielefeld. Source
