define equilibrium theory of island biogeography
idea that community patterns on islands depend on the spatial configuration of isolated communities and rates of colonization and extinction
define a facilitation view of succession
early species make sites more suitable for arrival of next species
what is a seral stage?
each community type during succession
populations that occupy discrete, spatially isolated patches and that are linked by infrequent migration between patches
what are some limitations to the equilibrium theory of island biogeography? (4)
evolution/speciation isn't incorporated, we live in a non-equilibrium world, too simplistic, not completely universal
define landscape ecology
the study of causes and consequences of spatial heterogeneity
what two main factors affect the number of species on "islands"?
size of the island and isolation
define an inhibition view of succession
colonizing species inhibit arrival/growth of later species
what is a sere?
a sequence of communities occurring during succession
define a tolerance view of succession
species at "climax" are those best able to tolerate reduced resource conditions created earlier in succession
