The evolution of lifespan is a central question in evolutionary biology, begging the question why there is so large variation among taxa. Specifically, a central quest is to unravel proximate...

The results of this study provide consistent and robust evidence that populations of golden jackals from Africa and Eurasia represent distinct monophyletic lineages separated for more than one...

During the past decade, melanins and melanogenesis have attracted growing interest for a broad range of biomedical and technological applications. Despite considerable advances, applied research on...

Melanins are biological pigments that occur in two chemical forms, eumelanin and pheomelanin. Here authors report for the first time that an insect (grasshopper) synthesizes pheomelanin.

The introduction of invasive species, which often differ functionally from the components of the recipient community, generates ecological impacts that propagate along the food web. This review...
