This North American species is the most widely spread freshwater crayfish worldwide, and is one of the worst invasive species due to its severe impacts on the structure and functioning of freshwater ecosystems. The results of the study may help to prevent the further expansion of the red swamp crayfish and to avoid potential future invasions.

The colonisation of new suitable habitats is crucial for species survival at evolutionary scale under changing environmental conditions. However, colonisation potential may be limited by philopatry that facilitates exploiting successful habitats across generations. This study examined the mechanisms of long distance dispersal of the philopatric loggerhead sea turtle (Caretta caretta) by analysing 40 sporadic nesting events in the western Mediterranean. The analysis of a fragment of the...

The grey wolf (Canis lupus) is an iconic large carnivore that has increasingly been recognized as an apex predator with intrinsic value and a keystone species. However, wolves have also long represented a primary source of human–carnivore conflict, which has led to long-term persecution of wolves, resulting in a significant decrease in their numbers, genetic diversity and gene flow between populations. This review serves as an analytical summary of the main findings from wolf...
