When ecologists study populations, what types of changes are they monitoring?

a. changes in growth rates

b. changes in distributions

c. changes in genetic compositions

d. all of the above.

e. only b and c are correct?

Ecologists study populations by studying changes in growth rates, distributions and genetic compositions. I think through population studies, ecologists can get an idea about the conditions that are influencing the populations being studied. They can also discover how these changes would impact other interacting populations.
