Pollinator shifts are considered to drive floral trait evolution, yet little is still known about the modifications of petal epidermal surface at a biogeographic region scale. Here, how independent...

Temporal variability in primary productivity can change habitat quality for consumer species by affecting the energy levels available as food resources. However, it remains unclear how...

Animal movement often changes with habitat quality. Butterfly movements may be influenced by structural attributes of habitat patches or may reflect the distribution of food, mates, host plants or...

First review and synthesis paper on feather fault bars. A model is proposed to link fault bar severity with the propensity to produce fault bars and the intensity of the perturbation. This study...

Many theoretical models on the evolution of nestling begging assume this behavior is costly, so that only nestlings in real need of food would profit from giving intensive signals to parents....
