Ecological biogeography
|
applying ecological theory to explain distribution patterns
|
|
Shoener
|
Came up with one of community ecology's laws
|
|
Species-distance relationships
|
tend to get negative relationship between species richness and island isolation
|
|
Immigration
|
movement of potential founding population onto island
|
|
Establishment
|
founders survive and form a population
|
|
Colonization
|
includes immigration and establishing a population
|
|
Extinction
|
loss of previously existing population
|
|
MacArthur and Wilson
|
Equilibrium Theory of Island Biogeography
|
|
Rescue Effect
|
on island close to mainland, extinction may be low because immigration is high
|
|
Target Effect
|
larger islands get more immigrations
|
|
Harmonic biota
|
balanced assemblages, similar in composition to source biota
|
|
Disharmonic biota
|
unbalanced or non-random subset of source
|
|
Island Chains
|
islands are nested subsets of a richer island when look at species composition
|
|
Supertramp species
|
found only on small and/or isolated islands with few other species
|
|
Density composition
|
caused by low levels of competitors or lack of predators
|
|
Island rule
|
different groups of mammals exhibit different trends in insular body size
|
|
Areography
|
description of patterns and underlying mechanisms responsible for size, shape, and location of geographic ranges
|
|
Macroecology
|
multi-scale approach to investigating assembly and structure of biotas
|
|
Deductive
|
hypothesis driven scientific method
|
|
Inductive
|
searching for patterns, building hypothesis/theory
|
|
Rappoport's Rule
|
Broadest ranges in the North
|
|
Nestedness
|
tendency for ecological communities from species-poor sites to form proper subsets found in richer sites
|
|
Bergmann's Rule
|
body size of endotherms tends to increase with latitude
|
|
Allen's Rule
|
in endothermic vertebrates, those living in hotter environments have longer appendages
|
|
Gloger's Rule
|
darker colors occur in more humid environment
|
|
Species richness
|
number of species in an area
|
|
Diversity
|
indices combines richness and evenness
|
|
Penninsular Effect
|
species richness tends to decrease from continental interior toward terminus of peninsula
|
|
Centinelan extinction
|
undiscovered species going extinct before they can be described
|
|
Gigantopithecus
|
Found in China and India, similar to gorillas but much larger
|
|
Adapids
|
resemble modern lemurs
|
|
Omomyids
|
resemble modern tarsiers
|
|
Black Death
|
1348-1351 half of Europe died
|
|
Lonnie Thompson
|
chronicled CO2 in tropical ice cores and documented melting of tropical glaciers
|
|
Diamond
|
Assembly rules for Islands
