Define Population
all of the organisms in the same place at the same time that can reproduce together
Define Population Density
The amount of organisms in an area
Define Population Distribution
the pattern in which organisms of a population are spread throughout the range
What is clumped population distribution?
Populations that live together in groups, often to act as safety in numbers.
What is uniform population distribution?
Populations that are evenly spaced apart from each other, often because resources are scarce.
What is random population distribution?
Populations where there’s no rhyme or reason to how they organize themselves, often because resources in that area are abundant and location in irrelevant.
How do you calculate population density?
individuals in an area/size of the area
How to calculate population size with quadrants?
total number of individuals in each quadrant/ area of those quadrants, then cross multiply that with x/total size of area to get total population.
How to calculate population size using mark and recapture?
Mark a certain amount of creatures, on recapture, cross multiply that number marked with the number recaptured, then divide it by the number of marked in the recapture.
What types of factors affect population?
Biotic, Abiotic, and Intrinsic
