Limiting Factors



A limiting factor is a factor that limits the ability for species to thrive. There are two types of limiting factors: density-dependent and density-independent. A density-dependent limiting factor is affected by the density of a population. In thick boreal forest, a density-dependent limiting factor can be light, which often won't reach the ground until a tree falls. Saplings will also have limited space to grow in this scenario.

A density-independent limiting factor is a factor which is unaffected by the size of a population. One such limiting factor througout taiga is temperature. Many species cannot survive the winters which taiga experiences. Cold temperatures will generally afftect small and large populations the same.Another density-independent limiting factor is a volcanic explosion. Plants and animals will be affected the same regardless of their population size.
