Document Summary
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. Ecological: migrate to more favourable environment conditions. Evolutionary: adapt to changing conditions, go extinct (global/local) Field mustard in california a. weis (2007) Studied uci arboretum in wet and dry year: observed that selection was directional from early flowering. Strong selection for early flowering plants: compared seeds from 1997 and 2004. Extinction is normal, but the sped up rate is not: 99% of all species that have existed so far are extinct, massive habitat destruction over past century. Three types of extinction: background extinction (due to natural causes, mass extinction (due to catastrophe, anthropogenic extinction (due to humans) Study of species and environments affected negatively by humans. Multidisciplinary but with a core ecological and genetic framework. Effects of habitat fragmentation on population ecology/demography: ex.
