Population Regulation in an Ecosystem With regard to the population size of a species and what factors may affect them, two factors have been defined. They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how ...
Density- Example 2:A population with low density will have individuals spread over a larger area but with a lesser number of individuals per unit area. Such a spread of population usually makes the chances of mate encounter bleak and rare. Thus, this deprives the individuals in this population...
density-independent factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area). Density-independent factors often arise from physical and chemical (rather than biological) phenomena. Such...

Density-dependent factor, in ecology, any force that affects the size of a population of living things in response to the density of the population (the number of individuals per unit area). They often arise from biological (rather than physical and chem

The brown marmorated stink bug, Halyomorpha halys, is a pentatomid bug of Eastern Asian origin that became an economically relevant pest in the Eurasian and American continents. Management of this species is limited to use of chemical insecticides: an in
The classic definition of heterochromatin originated from staining mitotic chromosomes74 and later came to be associated with histone modifications75. We now have a more nuanced understanding of the molecular details, including several types of repressive histone modifications and associated proteins and the...

Limiting factors may be classified into density-dependent and density-independent, based on whether they depend on population density or not.Definition of a limiting factor.
