BIO 327 Lecture Notes - Lecture 8: Hurricane Katrina, Mercedes-Benz Superdome, Regional Climate Levels In Viticulture
Document Summary
Species current correlation with climate indicates its true climatic niche. Species can move in response to climate. No adaptation or evolution to changing climate. Population density is an unreliable indicator of habitat quality. Just b/c a place has higher population density does not mean it is a better habitat. Example of this is shelters during natural disasters such as the superdome during hurricane katrina. Need to be super careful on making decisions based on abundance and density. Stats that should actually look at should be mortality and reproduction rates. So there is a net outflow of individuals. So there is a net inflow of individuals. Round trip momvement, usually seasonal, to escape harsh environmental conditions. Conditionals usually related to temperature or food availability. Temporary reduction in activity and metabolic rate to survive harsh environmental conditions. The largest factor of listing and decline of species is habitat loss and degredation.
