Logistic growth is density-dependent

WitrynaDensity-dependence has been shown a rather general rule for plant populations which acts at different life cycle stages. Density dependence has been found in all aspects of plant demography: germination, fecundity, etc. The density-dependent regulatory mechanisms keep the population at an equilibrium density ( Mokhtassi-Bidgoli et al., … WitrynaPopulation ecologists follow the fate of same-age cohorts to a. determine a population’s carrying capacity. b. determine the birth rate and death rate of each group in a population. c. determine if a population is regulated by density-dependent processes. d. determine the factors that affect the size of a population.

Logistic growth curves are density-dependent. True/False

The study system Witryna25 wrz 2014 · Density dependence occurs because the level of density in an organizational population determines the level of competition between organizations. In turn, competition reduces the rate of organizational founding (the creation of a new organization) and increases the mortality rate of organizations.

Did you know?

WitrynaSimply using the maximum growth rate ever observed (or observed under laboratory conditions, etc.) may overestimate the strength of density dependence, because this observed value might have been the result of factors other than the low density of the population or the lack of competition. WitrynaThe relative role of density-dependent and density-independent variation in vital rates and population size remains largely unsolved. Despite its importance to the theory and ... ical logistic growth model (Verhulst 1838, Pearl and Reed 1920) but were inconclusive (Slobodkin 2001).
