What are three ways in which ecologists can estimate the size of a population?

Answer 1

The first way an Ecologist can estimate a population is to use, trap, check ,release. Another way is that lets say a ecologists counts 100 goats in 1 acre out of 100 acres. He then multiplies the number inside 1 acre with the total amount of acres.

Answer 2

Three ways ecologist can estimate the size of a population is by trap-mark-release methods,sample counts and evaluating the resource in the area .

The trap-mark and release method works by setting unharmful traps for the animals of your choice. Each animal that you are looking for are marked and then released. Later , more animals you are looking for are captured. Some animals will have marks, many will not. By analyzing these samples, ecologists can estimate the size of the population.

The sample count involves using a large area to count animals. Say, if there is a 100- acre area, filled with animals of the same kind. Take one acre and count the animals. Then multiply that number by 100 to equal a rough estimate of the population.

The resources in the area can provide valuable information. Say, you mwere looking for rabbits. it is a fairly small area, of about 1 sq. mile. The is not a lot of resources and plenty of natural predators. You can naturally assume about 20 or so rabbits living in the area.

Hope that helps.

Answer 3

Okay so, first just times 2 by 2.01. This should be roughly 4.02. Then times this by 6. This will roughly obtain the number of males, convert the answers to millions. Then count the number of genitalia in males, and the amount of "unprecendented pregnancies" hope this helped!

Answer 4

what are four pieces of information that ecologists use to determine the health of a population

Answer 5

A census, and estimations based on a survey or a capture-recapture experiment.
