Population Characteristics
This describes how many organisms make up a population
What is the size?
In this survey, an attempt to count all individuals is made.
What is a census?
This the number of individuals being born as a ratio of the total number
This is what the t stands for in the exponential growth model
What is time passed?
This magical bird dances better than anyone in the local ecology class
What is the woodcock?
This describes the number of organisms per unit area
What is population density?
This type of count is used for highly mobile populations
What is capture-recapture?
This is the ratio of individuals dying per total population
What is the death rate?
This is what the P stands for
What is the initial population size?
This keystone species reacts to the sound of running water with a frantic urge to build
What is the American Beaver?
This describes how a population is arranged in space.
What is population distribution?
In this type of count, squares of fixed sizes are used to sample a large population.
What is a quadrat sample?
This represents the difference between individuals being born and dying in a population
What is net growth rate?
What the A stands for
What is the value of the population after t time?
This large mammal in Maine is in decline in all parts of the state, but still managed largely by hunting permits
What is the moose?
This describes how a population is composed of individuals in different developmental stages.
What is age structure?
These two factors can make a capture-recapture count less accurate
What are marked animals dying or immigration out of a location?
It the birth rate is 0.8 and the death rate is 0.2, what is the net growth rate?
What is 0.6?
If a population is declining, the growth rate is less than this number
What is less than zero?
This large feline is similar to a bobcat, but prefers dense coniferous forests and shies away from humans
What is the Canada lynx?
Trees in an apple orchard would be described as having this distribution
What is uniform or even distribution?
This is why quadrats are regularly spaced.
What is to prevent biased samples?
This formula can be used to find the value of a population over time.
