Population Ecology Flashcards
What is Ecology?
The study of how organisms interact in an environment.
What is a Population?
the same species in the same area at the same time
What is Population Density?
the number of species per unit within an area at a specific time.
What is Population Range?
What is Spatial Dispersion Pattern?
Individuals In A Population Show A Species
Specific Pattern Of Spatial Distribution In Their Habitat
What is a Resource?
Any substance or object an individual or a population requires to grow, maintain, and
reproduce
What is Competition for Resources?
fighting or competing for substances or object
What is Carry Capacity (K)?
Maximum population size in a specific environment. Sustain over a longer time intervals
Why are Ecological Systems so complex?
What is the most fundamental, or least complex, ecological system?
Population
Which features of populations do ecologists study?
n
What is a Metapopulation?
Which factors would cause a local population to move to another suitable habitat patch within the
Geographic Range of the Metapopulation?
What are some Abiotic Factors & Biotic Factors that affect Population Density?
Which factors can increase, or decrease, the Carrying Capacity of an environment for a population over
time?
Which characteristics of an animal species would result in Clumped Dispersion?
Which characteristics of an animal species would result in Regular (Uniform / Even) Dispersion?
Which characteristics of an animal species would result in Random Dispersion?
How does Resource Availability in the habitat relate to clumped dispersion?
How does Resource Availability in the habitat relate to Regular (Uniform / Even) Dispersion?
How does Resource Availability in the habitat relate to Random Dispersion
