Document Summary

Lecture 12: climate effects on organisms, phenology and interactions: basic eeb principles and example of petm leads us to expect. Ranges of tolerance and ecological niche modeling: assume that a species is now found in places where conditions are suitable. Map where a species is found now. Measure ecological conditions they can tolerate there to produce an envelope of sustainability . Use gcm to predict how conditions will change. Map where conditions will be suitable in future: thus, predict how far the range will need to shift. Frost fragmentation from historical records, cadiz township, wisconsin. Hunting could not have done it alone: nut feeder pigeon was so successful because it beat the predator-avoidance strategy of oak and beech mast crops. In pre-settlement north america, there was always mast somewhere: colonial life-style allee effects likely, but not after massive loss of forest and fragmentation, remaining flocks searching for shrinking remnants of forests.
