Data from: Size-selectivity of predation by brown bears depends on the density of their sockeye salmon prey

Cunningham, Curry James
关键词:
Density dependence Foraging: behavior Selection: natural Fish
DOI:
doi:10.5061/dryad.77f5q
摘要:
ween density dependence and selective predation runs contrary to some aspects of optimal foraging theory and differs from many observations of density-dependent selecti
Data from: Partitioning the sources of demographic variation reveals density-dependent nest predation in an island bird population

摘要:
. Our results demonstrate that density-dependent nest predation can underlie the relationship between population density and fecundity even in a high-density
Data from: Intraspecific predator inhibition, not a prey size refuge, enables oyster population persistence during predator outbreaks

摘要:
t predation rates declined with increased predator density. Consistent with field surveys, field experiments demonstrated that conchs selectively consumed larger

摘要:
e consistent with the hypothesis that predation may reduce population density through negative density-dependence, while total nitrogen at adjacent shallow water
Data from: Understanding spatial distributions: negative density-dependence in prey causes predators to trade-off prey quantity with quality

摘要:
. The ‘functional response’ couples a predator's intake rate to prey density. Most widespread is a type II functional response, where intake rate increases asymptoti
Data from: Plant resistance reduces the strength of consumptive and non-consumptive effects of predators on aphids

摘要:
ors had no impact on the number of nymphs, aphid density or population growth on high resistance plants, whereas on low resistance plants, predat

摘要:
. The top predator’s behavioral type altered the food-web dynamics in a context-dependent manner. The system with an aggressive/nonchoosy top predator
