摘要:
te interactions. Empirical evidence that spatial variation in local host density drives parasite population density remains scarce, however. We test the coupling
Data from: Density dependence in demography and dispersal generates fluctuating invasion speeds

摘要:
. We show that density dependence in demography at low population densities—i.e., an Allee effect—combined with spatiotemporal variability
Data from: An evaluation of rearing densities to improve growth and survival of hatchery spring Chinook salmon

摘要:
gnificant difference was found in median fork length (P <0.001) for fish reared at different densities in the one year length was measured in the fall. Fish reared at high density
Data from: Density regulation in Northeast Atlantic fish populations: density dependence is stronger in recruitment than in somatic growth

摘要:
of density regulation on population biomass. 4. Statistically significant density dependence in recruitment was detected in a large proportion of populations
Data from: Nonlinear scaling of foraging contacts with rodent population density

rodent behaviour;enclosure experiment;Mastomys natalensis;Density Dependence
摘要:
Density-dependent shifts in population processes like territoriality, reproduction, dispersal, and parasite transmission are driven by change
Data from: Density-dependent movement and the consequences of the Allee effect in the model organism Tetrahymena

movement density-dependence Allee effect microcosm
摘要:
which led to negative densitydependence at low population densities and generally positive density-dependence at high population densities due to
Data from: Size-selectivity of predation by brown bears depends on the density of their sockeye salmon prey
负责人:
Cunningham, Curry James
关键词:
Density dependence Foraging: behavior Selection: natural Fish
摘要:
Can variation in prey density drive changes in the intensity or direction of selective predation in natural systems? Despite ample evidence of
Data from: Scale-dependent shifts in the species composition of flower visitors with changing floral density

Foraging behavior Flower visitation Pollination Seasonal variation Density dependence Floral rewards Nectar Pollen Flower handling time Search speed
摘要:
, including plant population dynamics and the evolution of flowering phenology. Many studies have found effects of floral or plant density
Data from: Density-dependent habitat selection predicts fitness and abundance in a small lizard

摘要:
Density-dependent habitat selection has been used to predict and explain patterns of abundance of species between habitats. Thermal quality
Data from: Partitioning the sources of demographic variation reveals density-dependent nest predation in an island bird population

摘要:
, while also evaluating how biotic and abiotic factors jointly shape demography. We examined the effects of population density and precipitation on fecundity
