Definition of density independent

WebPopulation Regulation - Key takeaways. Population regulation refers to the ecological processes ( biotic and abiotic factors) by which the growth of populations is limited, due to the effects on birth and death rates. There are two different kinds of limiting factors- density-dependent and density-independent limiting factors. WebNegative density-dependence, or density-dependent restriction, describes a situation in which population growth is curtailed by crowding, predators and competition. [citation needed] In cell biology, it describes the reduction in cell division. When a cell population reaches a certain density, the amount of required growth factors and nutrients ...
