Linnaeus

1700’s classifying species, species=unchanging. noted where species were found, starting ecological biogeography

Buffon, buffons law

environments that look similar in different regions contain different speices, paving way for historical biogeography

forster

plant diversity decreases as you move away from the equator

humboldt

plant species change with altitude, breast fed his daughter in a rainforest??

candolle

endemic species

Darwin (& wallace)

voyage on the HMS Beagle, galapogos islands, finches different beak shapes

dispersalism

species move across barriers (birds, floating seeds)

wegener (1912)
