Geography 316: Biogeography Fall 2002
Exam 2 Review
Review the following terms and concepts for the exam. Concentrate on lecture notes, rely on the text where noted
Patterns of Distribution:
Definition of Niche
Barriers to distribution
Endemism (neoendemics and paleoendemics)
Dispersal routes (Corridor, Filter, Sweepstakes)
Continuous distribution
Cosmopolitan distribution
Disjunct distribution and hypothesize why they occur
Eurytopic and Stenotopic Taxon
Evolution:
Theory of Natural Selection
Continuous versus Punctuated evolution
Adaptive radiation (examples)
Conditions needed for evolution:
isolation, appearance of a novel feature (mutation)
Examples and definition of Coevolution, Convergent evolution and
Divergent Evolution
Plate tectonics/C. Drift:
Geologic time scale (Know Eras. Epochs, periods and time scale)
Laurasia, Pangaea, Gondwana(land)
Process of plate movement: spreading, subduction, uplift
Time frame of major plate movements, their relation to the organisms present at the time
Historical Biogeography
Systematics *what is it?
Fossils : problems with fossil record / why fossils are important
Phylogeny : definition / assumptions/validity of assumptions
Phenetics (what it is & why it doesn’t work as well as phylogenetics)
Phylogenetic Classification
Evolutionary Systematics vs. Phylogenetic Systematics (Cladistics)
Should be able to follow a
phylogenetic tree and make hypothesis about it
Zoogeographic regions:
define and know something about each of them, as far as distinctive fauna and flora
what animals are associated with each region and why
Wallace's line
Climate Change:
Evidence of climate change Direct and Indirect measures
History (last 20,000 years or so)
Hypothesized mechanisms behind climate change
Remember to read the reserved readings
