Population Ecology

What is carrying capacity?

• A flexible number of babies that can be produced by the females within that environment

• the maximum number of individuals in a population that can be supported in a particular habitat (can change depending on conditions)

• the maximum number of individuals in a population that can be supported in a particular habitat (does not change over time)

• the minimum number of individuals in a population that can be supported in a particular habitat

What is a way to track the population density within a habitat?

What is a static population pattern?

• property of a population that can be assessed with a measurement or estimates taken with a difference in years

• property of a population that can be assessed with a measurement or estimates taken at two or more points in time

• property of a population that can be assessed with a measurement or estimate at a single point in time ( a "snapshot")

• a highly populated habitat with an increased death rate

Which Hypotheses suggests that predation or disease limits herbivores?

• top-down control hypothesis

• bottom- up limitation hypothesis

• predatory control hypothesis

• Waltins hypothesis

bottom-up limitation hypothesis suggests that .....

• the plants control/ have a major effect on things higher up in the food chain ( number of producers impact number of herbivores and so on)

• predation or disease limits herbivores

• plants provided the main source of nutrition or are poorly defend against herbivory

• plants provided poor nutrition or are well defend against herbivory

Draw and example of a r selected species

Draw an example of k selected species

if a species is known for producing multiple small offspring at a time, which then has a low survival rate which species selection would we expect it to have?

What are the 4 static population patterns?

• clumped, random, uniform, dispersion

• diversification, uniform, grouped, clustered

• inbreeding, impendant assortment, crossing over

• random, controlled, uniform, dispersion
