densiteettitekijöiden

Densiteettitekijöiden refers to factors that influence population density. These factors can be broadly categorized into density-dependent and density-independent factors. Density-dependent factors are those whose effects on the size or growth of a population vary with the population density. Examples include competition for resources such as food, water, and shelter, as well as predation and disease. As population density increases, these factors tend to become more intense, limiting further population growth. Conversely, density-independent factors affect a population regardless of its size or density. These can include natural disasters like floods, fires, and extreme weather events, as well as human activities such as pollution and habitat destruction. While density-dependent factors regulate population size around a carrying capacity, density-independent factors can cause sudden and drastic declines in population, irrespective of how crowded the population is. Understanding these factors is crucial for ecological studies, conservation efforts, and managing wildlife populations.
