Document Summary

Metapopulation: a set of local (sub) populations of a species that are linked by dispersal moung those populations (eg source-sink) Biome: a defined area if similar climate and vegetation type; it may contain different taxa in different regions. Larger animals can withstand higher stress levels (high food reserves) Berg(cid:373)a(cid:374)"s rule: we"ll ha(cid:448)e (cid:271)igger (cid:448)ersions of spe(cid:272)ies to(cid:449)ards poles. Rabbits introduces to port in australia, quickly spread across the country within 100 years. Dispersal: movement if species away from their homerange.

Successful dispersal involves: travel to a new area, withstanding the new conditions, establish a new population. Two main types of dispersal: jumps and diffusion. Cane toad: australia-introduced to control insect on the sugar cane crop. Ended up being very poisonous to other animals. Even eggs and tadpoles are poisonous to fish.
