Climate Change and Biodiversity Conservation 7.
Natural adaptation can take a number of forms, including acclimation, evolution, or migration.
There is rather poor information on the first two, but it is possible to make some rough quantifications for migration rates. The achievement of the migration rates given in Figure 1 depends on factors apart from temperature change. Migration is an issue for fauna as well as for flora. Others are associated with specific vegetation species or formations, such as Kirtland's warbler and Jack pine. Others, such as crossbill, may migrate in synchrony with the availability of transient food sources.
