Understanding why some individuals within populations are more prone to harbor parasites (and diseases) than others is an important biological question. Repeated measures on marked individuals over time are required to ...

Natural selection is expected to favor foraging behaviors that allow animals to maximize energy gain in novel situations. Whereas many species are known to regularly hunt prey and eat meat, squirrels are largely considered ...

Biologists have long recognized the importance of two native rodent species – California ground squirrels and voles – as important ecosystem engineers and prey for a suite of predators in California ecosystems. However, ...

Dietary flexibility allows animals to respond adaptively to food pulses in the environment. Here we document the novel emergence of widespread hunting of California voles and carnivorous feeding behavior by California ...
