The hypothesis that predispersal seed predators preferentially attack high-quality flowers, potentially masking negative effects of environmental stressors

Master variable controlling microbe operations, solubility and mobility of heavy metals, and mediating redox dynamics of riverine waters

Parental behaviors including female-pup interactions, vigilance, and antipredator behaviors that influence offspring survival and development

Population size or density of individual species within a habitat

Variation in organismal body size both within and between species, influenced by environmental and genetic factors

Behavioral displays performed by animals during mating season to attract mates or compete for breeding opportunities
