Interactions among global change pressures act in a non-additive way on bumblebee individuals and colonies

Insect-mediated pollination is fundamental for terrestrial ecosystems as well as for crop production. However, bee populations are declining as a consequence of different global change pressures. Even though these pressures do not act in isolation, their interactive effects have received less attention.

Combined effects of global change on bumblebees

The decline in bee populations has recently attracted much attention from researchers, conservationists and the general public, with insect-mediated pollination being a key process for terrestrial ecosystems as well as for crop production. The conclusions of different studies suggest that this decline is the result of pressures from different drivers of global change such as habitat destruction, pesticide use and climate warming. However, there is increasing evidence that these pressures do...

Impact of historical vs. anthropogenic factors on processes of genetic fragmentation

Impact of historical vs. anthropogenic factors on processes of genetic fragmentation
Inferring the demographic history of species is fundamental for understanding their responses to past climate/landscape alterations and improving our predictions about the future impacts of the different components of ongoing global change. Estimating the time-frame at which population fragmentation took place is also critical to determine whether such process was shaped by ancient events or if it was...

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.
