Population Ecology AP Bio Flashcards

10467555171	Uniform distribution	results from intense competition of antagonism between individuals	0
10467557088	Random distribution	occurs when there is no competition, antagonism, or tendency to aggregate.	1
10467618337	Clumping	is the most common distribution because environment conditions are seldom uniform.	2
10467623533	Adaptive radiation	the diversification of a group of organisms into forms filling different ecological niches.	3
10467680984	Logistic population growth	occurs when the growth rate decreases as the population reaches carrying capacity (represented by an S shaped curve on a graph)	4
10467685320	Carrying capacity	is the maximum number of individuals in a population that the environment can support.	5
10467690763	Exponential population growth	when the resources availability is unlimited in the habitat, the population grows at a constant rate. (represented by a J shaped curve on a graph)	6
10467909549	Disruptive selection	extreme traits are favored over intermediate traits	7
10467911379	Stabilizing selection	intermediate traits are favored over extreme traits	8
10467917634	Directional selection	a single phenotype is favored causing a shift in one direction towards one of the two extreme phenotypes.	9
