Adaptation as Migration

Stress hormone dynamics: an adaptation to migration?

The hormone corticosterone (CORT) is an important component of a bird's response to environmental stress, but it can also have negative effects. Therefore, birds on migration are hypothesized to have repressed stress responses (migration-modulation hypothesis). In contrast to earlier studies on long-distance migrants, we evaluate this hypothesis in a population containing both migratory and res...

Tool use as adaptation

Tool use is a vital component of the human behavioural repertoire. The benefits of tool use have often been assumed to be self-evident: by extending control over our environment, we have increased energetic returns and buffered ourselves from potentially harmful influences. In recent decades, however, the study of tool use in both humans and non-human animals has expanded the way we think about...

Division as modified migration

Division as modified migration dividing cell mimics two half cells migrating away from each other, according to Chris Janetopoulos, Peter Devreotes, and colleagues (Johns Hopkins University, Baltimore, MD). A gradient of PI(3,4,5)P 3 appears to help the two ends of the cell to expand outwards, even as the middle of the cell favors contraction. Devreotes has long studied PI(3,4,5)P 3 involvement...
