Density-dependent factors


Population dynamics / Populationsцkologie

Factors affecting populations are divided into density-independent and density-dependent factors. Density is a factor when related to the number of individuals in a population:
Intraspecific competition: In-game competition for food, reproduction partners and habitat
Specific predators: Predators that are prey to the prey in a predator-prey relationship. If the number of prey animals increases, the number of robbers increases as well.
density stress: Frequent encounters with conspecifics leads to the release of stress hormones and aggression (for example, in animals that are usually individuals)
parasitesThe higher the population density, the easier it is for parasites to spread
Infectious diseasesWith increasing population density, the possibility of transmission of infectious diseases by bacteria or viruses also increases
