What is the Lincoln Index used for in ecology?

Back

The Lincoln Index is used to estimate population size in wildlife studies, particularly through the Mark, Capture, Recapture method.

Front

What are some limitations of the Mark, Capture, Recapture method?

Back

Limitations include the assumption of a closed population, potential for marking effects, and the need for equal catchability among individuals.

Front

What is the role of temperature in an ecosystem?

Back

Temperature influences metabolic rates, species distribution, and seasonal behaviors of organisms within an ecosystem.

How do biotic and abiotic factors interact in an ecosystem?

Back

Biotic and abiotic factors interact to shape the environment; for example, plants (biotic) can affect soil composition (abiotic) and vice versa.
