Document Summary
Feedback mechanisms: positive feedback mechanisms influence movement of ghg between sinks and sources, ex. 2: ex. increased warming reduced rainfall increase dust storms high atmospheric aerosol concentrations cooling (cid:374)ot going to offset the warming. Climate change and conservation biology: climate change and forest ecology, less rainfall = forest will disappear grasslands will expand, more rainfall = mudslides. Zooplanktons may shift offshore and to deeper water: caribou migration south to calving grounds (to give birth) is cued by day length; plant growth (on calving ground) is cued by local temperature; in west. Increase in primary production for some taxa, water and heat stress for others: alteration of rainfall patterns, wetter north, drier mid-latitudes, loss of arid, marginally productive habitats. Impaired/enhanced biogeochemical cycling; increased decomposition particularly important: altered arctic-temperate-tropical connectivity, ex. weather, range shifts (for those species that can, ex. soil characteristics, northern movements of sub-arctic taxa, pop fragmentation, genetic consequences (european blackcap)
