Data from: Size-selectivity of predation by brown bears depends on the density of their sockeye salmon prey
- 负责人：
- Cunningham, Curry James
- 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
Data from: Density-dependent energy use contributes to the self-thinning relationship of cohorts

- 摘要：
- novemaculeata and tank size to partition the effects of competition from metabolic scaling. We found that self-thinning can be density dependent and that change
Data from: Balancing food and density-dependence in the spatial distribution of an interference-prone forager

- DOI：
- doi:10.5061/dryad.s8n05
- 摘要：
- Foraging distributions are thought to be density-dependent, because animals not only select for a high availability and quality of resources, but als
Data from: Parental care trade-offs and life history relationships in insects

- 摘要：
- , but that allometric scaling of egg size and lifetime fecundity may depend on whether care consists of provisioning (density-dependent offspring survival

- 摘要：
- -dependent mechanisms shaping SSD in frogs. Male size was weakly associated with SSD in all size classes, and we found no significant association among SSD, male size

- 摘要：
- mulate phylogenetic branching under linear negative diversity-dependent and diversity-independent models and estimate from the simulated phylogenies the maximum
Data from: Novel host plant leads to the loss of sexual dimorphism in a sexually-selected male weapon
- 负责人：
- DOI：
- doi:10.5061/dryad.5p19k
- 摘要：
- -selected weapons and ornaments frequently influence fitness and often have heightened condition-dependence in response to nutrition. Condition-dependence
Data from: Local climate determines intra- and interspecific variation in sexual size dimorphism in mountain grasshopper communities
- 负责人：
- DOI：
- doi:10.5061/dryad.c5097
- 摘要：
- . Within species, we found a positive effect of temperature and a negative effect of elevation on body size, especially on condition-dependent measures of body size

- 摘要：
- When populations grow or decline, habitat selection may change due to local density-dependent processes, such as site dependence and int
