Climate change and the evolution of loggerhead sex-ratio in Cabo Verde

[EN] Global warming can affect nesting success of sea turtles due to the rise of the sea level and the subsequent increased inundation or erosion of nesting beaches. Moreover, it can reduce male production to levels that can alter reproduction due to their temperature dependant sex determination (TSD). Now, mean nest temperatures all around the world predict a predominance of female hatchlings, and this trend may increase with global warming in the next decades.

The eastern Atlantic juveniles of loggerhead sea turtles: Where do they come from and how do they distribute?

[EN] After hatching, loggerhead sea turtles (Caretta caretta) enter in the sea and start the ocean phase of their lives, where juveniles inhabit pelagic feeding areas during 6-12 years. In the Atlantic Ocean, the central and the eastern feeding grounds harbor loggerhead juveniles from different nesting populations, constituting the designated mixed stocks. We studied the distribution of juveniles in the Eastern Atlantic comparing mtDNA sequences from canarian individuals with samples from Azores, Madeira and the Atlantic coast of Andalusia.

Datos sobre la herpetofauna del Algarve suroccidental (sur de Portugal).

[ES] Entre los días 16 y 20 de abril de 1981 se realizó un viaje a la región del Algarve (sur de Portugal), durante el cual se colectó un cierto número de ejemplares de diversas especies de anfibios y reptiles. Analizando los resultados obtenidos hemos creído interesante la publicación de esta nota con el objeto de aportar datos acerca de la distribución geográfica de dichas especies, ampliando en algunos lo conocido hasta el presente en base sobre todo a los trabajos de CRESPO (1971, 1972 y 1975), así como proporcionar información sobre biometría y biología de las especies encontradas.
