Testing proximate causes and ultimate explanations of social cue use for habitat selection by songbirds
… whether Yellow Warblers discriminate between conspecific song categories social cues with different information about habitat quality. Second-category song broadcast attracted more Yellow Warblers to breeding habitat than first-category song did, highlighting that yellow warblers prefer to use …

An integrative approach to testing density effects in a migratory songbird, the Prothonotary Warbler (Protonotaria citrea)
… fluctuate around local carrying capacity through density-dependent processes such as competition, predation, and disease. Once subject to debate, ecologists now recognize density dependence as a conceptual cornerstone of population biology. Yet despite >50 years of research, key questions persist …

Connections between individual dispersal behavior and the multi-scale distribution of a saproxylic beetle
… influenced by log size and the presence of conspecifics, although aggregation associated with conspecific attraction did not occur because emigration balanced immigration. Additionally, population growth rate showed negative density dependence in post-settlement experiments. Finally, I …

Possible Effects Of Climate Change On Induced Defenses In Tadpoles
… of predator cue present in the water, conspecific density, and abiotic stressors may all reduce tadpoles' ability to respond to predators. Thus, some tadpoles may not be able to perform well in conditions with shortened pond hydroperiods and changing community compositions.

The Role of Climate Variability in Duck Population Ecology
… survival. In contrast, a negative effect of conspecific density on prefledging growth seemed to carryover to influence postfledging survival, and possibly first-year breeding probability. Fourth, examining breeding dates of individually marked females, I found that early-nesting species …
