The wide-ranging Eurasian species Zootoca vivipara (Lichtenstein, 1823), of the family Lacertidae (Reptilia), is a rare species within the family, possessing multiple sex chromosomes (male Z1Z2Z1Z2/Z1Z2W female). In addition, the intense reorganization of this W sex chromosome is accompanied by active subspeciation and the formation of 4–5 cryptic taxa. Leer más.
This study also further underlines the extraordinary biological value of the relatively small forest patches (less than 3000 km2) of the Eastern Arc, which contain more species of chameleons than any other area in mainland Africa. Leer más.
The microbial diversity was strongly marked by seasonality, with no sex effect and a marginal life stage and annual effect. The microbiota showed seasonal fluctuations along the two sampled years, primarily due to changes in the relative abundances of fermentative bacteria (mostly families Lachnospiraceae and Ruminococcaceae), without any major compositional turnover.

We describe a new species of Proctoporus from the scientifically unexplored southern sector of the Otishi National Park (Region Cusco) in Peru, on the basis of molecular and morphological characters. Seven type specimens were obtained from six localities between 3241–3269 m a.s.l. within a radius of ca. 1.5 km in a Puna valley. Leer más
