Topic 9: Biogeography
� What is biogeography?
� What are the different disciplines of biogeography?
� What are important concepts in biogeography?
� Herpetological examples
What is biogeography?
� Study of past and present ___________, ___________ and _______ of organisms
� Based on premise that history of _______ and _____________ are interconnected
� Addressing why organisms have the patterns of distribution that they have
What is biogeography?
Biogeographic
Distribution
HistoryEcology
Organism Environment Vicariance Dispersal
Phylogeny
All of these nested factors influence the distribution and abundance
of organisms, either directly or indirectly
What are the four disciplines of biogeography?
� __________ biogeography
� __________ biogeography
� __________ biogeography
� _____________________
� Each of these focuses on different factors that influence distribution and abundance
� Each has something to say about why Amphisbaenidae are distributed
Pough et al. 2004, Fig. 4-22
� ___________ biogeography� How distributions have
been shaped by organismal biology
� ___________ biogeography� How presence/absence and
diversity are determined on islands
� ___________ biogeography� How distributions have
been shaped by the Earth’s history
� Phylogeography� Next lecture
� Important considerations when studying frog distributions� Pipidae� Pelobatidae� Megophrydae
Pough et al. 2004, Fig. 3-27
