population ecology

Generalist

Broad niche, adaptable to many environments, less likely to go extinct

Specialist

narrow niche, less adaptable, more likely to go extinct

R species

no care.

short lifespan, quick reproductivity, many offsrping, small offspring, fast population rate

K species

With care

Long lifespan, slow reproductivity, few offspring, large offspring, slow growing population rate

Type 1 survivorship curve

low death rate as an infant

many individuals live to an old age

Type 2 survivorship curve

,pderate death rate individuals die at all ages

Type 3 survivorship curve

high death rate many indviduals die young, few live to old age

Carrying capacity

the max amount of individuals that the resources in an environment can support

Overshoot

when a population exceeds its carrting capacity

Die back

a sharp, sudden decline in a population when its size severely exceeds the environment's carrying capacity

Biotic potential

maxiumum reproductive rate of a population in ideal conditions

Density dependent

affects the size of the population more significantly with higher populations

diesease, competition and predation

Density independent

affects the size of a population of living things regardless of the desnsity of the population

food or nutrient limitation, pollutiants in environement, climate extreme
