2、cience, and Industry DivisionSummaryRecently projected climate changes could have widespread effects on wildlifespecies. These effects might be positive or negative, depending on the species. Someeffects might include extinction, range shifts, mismatches in phenology (timing ofpollination, flowering
3、, etc.), and population changes. Effects of climate change onwildlife have been reported for some species and populations in localized areas. Manyscientists contend that climate change acts in concert with other variables (such ashabitat) to affect species. If the effects of climate change are wides
4、pread, there isuncertainty on how wildlife will adapt. Some suggest that evolution and migration willenable species to adapt, whereas others contend that adaptation will be minimal becauseof limited habitat, and changes in climate that may occur more rapidly than adaptationcan respond.IntroductionCl
