Dispersal capacity explains the evolution of lifespan variability

The evolutionary explanation for lifespan variation is still based on the antagonistic pleiotropy hypothesis, which has been challenged by several studies. Alternative models assume the existence of genes that favor aging and group benefits at the expense of reductions in individual lifespans. Here a new model is proposed without making such assumptions.

Liberalization of the Common Agricultural Policy could affect Cinereous vulture

Farmland abandonment or “ecological rewilding” shapes species distribution and ecological process ultimately affecting the biodiversity and functionality of ecosystems. Land abandonment predictions based on alternative future socioeconomic scenarios allow foretell the future of biota in Europe. Here, how these forecasts may affect large?scale distribution of the Cinereous vulture, an apex scavenger closely linked to Mediterranean agro?grazing systems, is investigated .

Landscape change promotes the emergence of a rare predator-prey interaction

Diet studies provide basic natural history information to understand food web dynamics. However, measuring the dietary breadth of rare, elusive species is extremely challenging due to their scarcity and/or cryptic behavior. Here, for the first time, an uncommon predatory interaction –nest predation– between two of the most elusive and rare species in Europe, the Iberian lynx and the red-necked nightjar is documented.

Effects of artificial lights for ecotourism on little penguins

Wildlife watching is an emerging ecotourism activity around the world. In Australia and New Zealand, night viewing of little penguins attracts hundreds of thousands of visitors per year. As penguins start coming ashore after sunset, artificial lighting is essential to allow visitors to view them in the dark. This alteration of the nightscape warrants investigation for any potential effects of artificial lighting on penguin behavior.

The use of roads in protected areas and its effects on avian scavenger guild

The expansion of road networks and the increase in traffic have emerged in recent years as key threats to the conservation of biodiversity. This is particularly concerning in many protected areas because the increase of recreational activities requiring the use of vehicles. Effects of roads and traffic within guild scenarios and ecological processes remain however poorly known. This study examined how road proximity and traffic intensity influence patterns of resource use in an Old-World...
