Snake Fungal Disease, first confirmed in a captive rat snake in 2006, has now been confirmed in 14 species of wild snakes across the Eastern and Midwest United States. Leer más.





![]() | Habitat fragmentation may involve a loss of genetic diversity and increments the vulnerability to species persistence. It could be a particular issue when coupled with other negative factors as the predicted climatic changes and the emergence of infectious diseases. In Southern Iberian Peninsula several endemic amphibian species have confined and fragmented distributions, including the Betic midwife toad Alytes dickhilleni. Herein, we present the first range-wide assessment of genetic diversity and structure in this species, using mitochondrial and microsatellite data. A mitochondrial fragment of the ND4 gene was amplified for 65 individuals and a set of 20 microsatellite loci, specifically developed for this species, was genotyped for 490 individuals from several sampling sites distributed across the species entire range.

Los tejidos musculares del ser humano tienen la capacidad de regenerarse ante cualquier daño que sufran, pero cuando el daño es causado por la mordedura de una serpiente venenosa, esa capacidad de regeneración se pierde. Leer más.
