摘要:
of density regulation on population biomass. 4. Statistically significant density dependence in recruitment was detected in a large proportion of populations

摘要:
. We show that density dependence in demography at low population densities—i.e., an Allee effect—combined with spatiotemporal variability

摘要:
which led to negative densitydependence at low population densities and generally positive density-dependence at high population densities due to

摘要:
of the demographic factors that regulate populations. Intraspecific competition is an especially important ecological process because it generates negative density dependence

摘要:
-density function warrants that density-dependence in ecological models, such as parasite transmission models, must be parameterized with care.

摘要:
; and (3) environmental characteristics can be related to population differences in density-dependent relationships.
