Seasonal timing in different environments: comparative studies in Stonechats

Seasonal timing in different environments: comparative studies in
Stonechats. Stonechats from four populations (Kenya, Sibiria,
Ireland, Austria) were compared during their first year of life at
the Max-Planck Research Centre for Ornithology in Andechs, Germany.
They differed in temporal patterns of their seasonal behavior and
in their reaction norms to important Zeitgebers (e.g.,
photoperiod). These differences were taylored to their native
habitats, and there is evidence that they can rapidly be modified
via micro-evolution. Implications for adjustment to changing
seasonal conditions (climate change) are discussed.
