community ecology

Question 1

Anolis ecomorphs

Answer 1

morphologically similar but not closely related groups occupying similar niches

Question 2

Hutchinson’s rule

Answer 2

coexisiting species must differ in size by at least 1.6X to avoid competition

Question 3

anolis species avoid intraspecific competition

Answer 3

through different size, bite force, prey preference, and micro habitat use

Question 4

ecological release

Answer 4

expansion of niche when limiting competitors are removed

Question 5

3 niche axes in the lizard community

Answer 5

1. size
2. perch height (habitat)
3. prey type

Question 6

biomechanical factor affecting community in Draco lizards

Answer 6

wing loading (influences gliding and perch height)

Question 7

example of physiological tolerance influencing species distribution

Answer 7

Eleutherodactylus tolerates higher temps and water loss than native frogs

Question 8

historical neutrality

Answer 8

patterns shaped by past events like glaciation, not current interactions

Question 9

community ecology

Answer 9

study of the interactions among groups of species coexisting within a region
- the interaction of 3 or more species in a population
