BY
THOMAS T. MOORE*
Animal migratons are important to the healthy function of many
ecosystems. When biotic and abiotic cues are altered by climate
change, migrations may be disrupted Clmate change has the potential
to disrupt these migrations by altering habitat, changing resource
availability, increasing habitat disturbance, changing phenology, and
stopping migration. The act of migration (i. e., potentially traveiling long
distances) causes species to confront a wide range of climatic changes
that make adaptation especially difficult. Future research goals should
stnve to obtain long-term data on migrations and better understand
how-and whether-migratory species adapt to changes in climate.
Future management techniques should strive to maximize the abiity of
the target species to adapt to climate change by providing species with
more options (e.g, protecting alternative migration corridors) to react
to changes in their habitat.
