Flashcards in Part 3 Deck (10):
1

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

2

define a facilitation view of succession

early species make sites more suitable for arrival of next species

3

what is a seral stage?

each community type during succession

4

define metapopulations

populations that occupy discrete, spatially isolated patches and that are linked by infrequent migration between patches

5

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

6

define landscape ecology

the study of causes and consequences of spatial heterogeneity

7

what two main factors affect the number of species on "islands"?

size of the island and isolation

8

define an inhibition view of succession

colonizing species inhibit arrival/growth of later species

9

what is a sere?

a sequence of communities occurring during succession

10

define a tolerance view of succession

species at "climax" are those best able to tolerate reduced resource conditions created earlier in succession
