Here we describe the Levantine population as a new subspecies and present biogeographic scenarios for its origin and diversification. The new subspecies is genetically highly diverse, and it forms a sister lineage to Pseudopus from the remaining parts of the range according to mtDNA. It is the largest-bodied of the three subspecies, but occupies the smallest range. Leer más.
We found that poor-quality reference pictures could lead to an increasing difficulty to achieve a correct match when time since first capture rose. Consequently, individual photo-identification using AmphIdent software is a reliable tool to aid in the monitoring the Pyrenean brook newts, provided that pictures are taken with care, reference images are regularly updated and observers are properly trained to use the software and interpret images.

We found that rivers are semi-permeable obstacles for both larviparous and pueriparous salamanders, although they appear to be more effective barriers for the latter when rivers with similar attributes are compared. We also found that river width and possibly the presence of crossing structures may influence the genetic barrier effects of rivers in fire salamanders. This is one of the very few studies in amphibians showing how different reproductive strategies influence the barrier effects imposed by rivers. Leer más.
Narrasti espezie berri bat azaldu zaigu Euskal Herrian: sugandila italiarra (Podarcis sicula). Zoritxarrez ordea, espezie kanpotarra da, gaitasun inbaditzailea duena gainera, hau da, bertako espezieak ordezkatu ditzazkena. Bi populazio aurkitu dira, Bilboko Etxebarria Parkean bat eta Getariako Arratoian bestea. Bilboko kasuan gainera, indibiduo gazteak ere aurkitu dira, eta horrek espeziea ugaltzen ari dela pentsarazi dezake.
Tenemos una nueva especie de reptil en Euskal Herria: la lagartija italiana (Podarcis sicula). Por desgracia, se trata de una especie alóctona con capacidad invasora, es decir, capaz de sustituir a las especies autóctonas. Se han localizado dos poblaciones, una en el Parque Etxebarria de Bilbao y otra en el Ratón de Getaria. En el caso de Bilbao, además, se han encontrado individuos juveniles, lo que nos hace pensar que la especie puede estar reproduciéndose. Leer más.
