Document Summary

Lecture 23 bio220 climate effects on organisms, phenology, and interactions. Ranges of tolerance, ecological niche modeling: assume species is now found in suitable condition, map distribution, measure ecological condition, predict how conditions will change, map suitable conditions in the future, predict range shift. Proghorns: good at running, not jumping, fences: killed, climate change migration hampered by human altered landscapes. Pikas in great basin: adapted to high, cold mountains; lethal temperature 27 c. Decreased pollination: phonological dislocation of bee activity, plants, bees, flowers react to different cues of becoming active in spring.
