Does high density encourage or discourage dispersal in certain species?

Factors that control tree seedling dynamics are critical determinants of forest diversity. We examined the role of density-dependent mortality and abiotic ... ... density dependent with density independent effects on vital rates and population trajectories. Our data and model do not support the hypothesized recent ... Most density-dependent factors are biological in nature (biotic), and include predation, inter- and intraspecific competition, accumulation of waste, and ... The two types of limiting factors are density independent and density dependent limiting factors. Density-Independent Limiting Factors. Picture. Rain in ... In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population. As population density increases the amount of deer food in the area declines; this decline in food affects deer body condition. Body condition serves as a ... Nov 22, 2024 ... Most density-dependent factors, which are biological in nature (biotic), include predation, inter- and intraspecific competition, accumulation ... ... density-dependent resource competition. Survival of individuals in ... density-independent environmental factors but not regulated by crowding. The ... For example, the mode of pathogen transmission might be one important factor (see Fenton et al. 2002 and references therein). The form of density dependence is ... It has been argued that bacteria communicate using small diffusible signal molecules to coordinate, among other things, the production of factors that are ...
