Document Summary
Logged tropical forest in amazonia - beef for burgers! Lecture 12 - biodiversity, extinction & conservation biology. Topics & concepts global climate change, rapid evolution, resurrection paradigm, components of biodiversity, biodiversity hotspots, types and causes of extinction, habitat fragmentation, sloss, keystone species, mvp, inbreeding in zoo animals. Wilson, c. keeling, a. weis: ecological & evolutionary consequences of global environmental change, what is biodiversity and why does it matter, the causes of extinction today, conservation biology ecological and genetic perspectives on a crisis-driven science. Keeling: longest direct measurement of co2 in the atmosphere. Increase in co2 as a result of burning of fossil fuels. Migrate to more favourable environmental conditions (=ecology) Difficult to migrate if you"re on a flat island or if you"re already on top of the mountain. Is there genetic variation for traits that would be important. Declining trend in various parameter (eg. emergence time, flowering time) Lines consistent with directional selection, but need studies to confirm not plasticity.
