ETYM Greek bios life + Eng. geography.
Dealing with the geographical distribution of animals and plants.
Study of geographical distribution of plants and animals.
Study of how and why plants and animals are distributed around the world, in the past as well as in the present; more specifically, a theory describing the geographical distribution of species developed by Robert MacArthur and US zoologist Edward O Wilson. The theory argues that for many species, ecological specializations mean that suitable habitats are patchy in their occurrence. Thus for a dragonfly, ponds in which to breed are separated by large tracts of land, and for edelweiss adapted to alpine peaks the deep valleys between cannot be colonized. + prikaži više
