|
Fredrick Clements |
said communities are predictable |
|
|
Henry Allan Gleason |
said communities are random assemblages of organisms |
|
|
Joseph Grinnell |
Grinnellian Niche habitat that an organism is capable of surviving in environmental emphasis |
|
|
Charles Elton |
Eltonian niche organisms role in the community species emphasis |
|
|
G.F. Gausse |
proposed the competitive exclusion principle |
|
|
Robert McArthur |
niche partitioning island biogeography theory (co-wrote with E.O. Wilson)
|
|
|
E.O. Wilson |
Island biogeography theory (co-wrote with Robert McArthur) |
|
|
Alfred Wilson |
Theory of Natural Selection Biogeographical Realms Father of biogeagraphy
|
|
|
Competitive exclusion principle |
if niches overlap then one species will out compete the other species Losers have to: live in marginal habitat, move away |
|
|
what are some of the ways we "weigh" species? |
Native v Non native Endemic v wide spread Unique v redundant Threatened v not threatened valuable to humans or not |
|
|
Patterns of Area with an example |
-As area increases, richness increases -Caribbean Islands: there were more reptiles and amphibian on larger islands like Cuba and Hispaniola than other smaller islands like Jamaica |
|
|
Patterns of latitude with an example |
-as you get closer to the equator richness increases -birds and vascular plant richness increase closer to the equator -tropics and coral reefs are also right along the equator. |
|
|
Rapaport's rule What did they find in the Orme paper? |
species range decreases as you get closer to the equator Orme: showed that the range decreases as you went farther below the equator also the data was taken all from the neartic region only
|
|
|
Patterns with complexity |
As complexity increases the richness increases tropics and reefs are very complex and allow many species to coexist |
|
|
patterns with isolation |
as isolation goes up there are less species studied on island near new guinea. the further away the islands were from the main land the less richness was found |
|
|
Cradle and museum |
lots of richness in tropics cradle- lots of energy leads to lots of mutations and allows for more biomass to live museum- no catastrophic events so there is not huge losses in biodiversity |
|
|
Island biogeography theory |
immigration v extincion leads to equillibrium more isolation and smaller areas lead to less richness |
|
|
Hutchinsons n dimention niche |
-fundamental niche- habitat that can support the individual -realized niche- habitat the organism can live in after also being restricted by competition |
|
|
who tested IBT? |
Wilson and Simberloff fumigating mangrove island in florida keys |
|
|
how have they tested niche compression |
Warblers with and without competition use different parts of the tree to forage |
|
|
Character displacement |
morphological traits the form when overlapping niche put selective pressures on species |
