2.1 SG or smth idfk Flashcards
Define population
The amount of individuals of the same species that are able reproduce
Define population density
Number of individuals in a given area
Define population distribution
Distance groups of individuals are spaced out at
Define distribution
Distance and pattern that organisms are set at
Define uniform distribution
Distanced at equal lengths and patterns
Define random distribution
Take a fat guess….distributed at random distances and patterns
Define clumped distribution
All grouped up with little to no distance and all close together
Why might populations be in different dispersion groups?
Availability of resources, social behaviors, the ecosystem, their place in the food chain, and territorial behaviors
How do you calculate population density?
Total population/ Total area
How do you find population size using quadrats?
Take some random samples, find their average, and then multiply by the total amount of quadrats
How do you find population size using mark and recapture?
Total # marked/ Total population size = # marked in recapture/total recaptured
