An Introduction to Biogeography

Center of origin

self explanatory

ecological constraint

factor that limits a species success

Buffon’s Law

disjunct regions have different species despite similar conditions

patterns of species ranges (wallace)

how species are spread over an area

Theory of Dispersal (Darwin)

animals move and populate and adapt to other areas

Extensionism

organism get to disjunct regions using land bridges

dispersalism

species travel after land splits

vicariance biogeography

species get isolated when land splits or possible land bridge in past

cladistics

attempt to reconstruct evolutionary history through phylogeneticsz

Generalized track

line connecting related species in different areas, evidence of vicarian event

fundamental area cladogram

shows how areas are related based on phylogenetic relationships

general area cladogram

phylogenetic trees with locations of species found
