Question

Write in short the density dependent and density independent population regulations.

Answer 1

The density of a population can be regulated by various factors, including biotic and abiotic factors and population size.

Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation.

Density-independent regulation can be affected by factors that affect birth and death rates such as abiotic factors and environmental factors, i.e. severe weather and conditions such as fire.

New models of life history incorporate ecological concepts that are typically included in r- and K-selection theory in combination with population age structures and mortality factors.
