Concepts

Selection on body mass accounting for juvenile survival until reproduction but may weaken after recruitment

Mortality from hunting that adds to natural mortality rather than substituting for it, resulting in net population-level effects

Colonization by winged adult insects as an often-cited mode of wetland colonization

Growth pattern where fish tend to become relatively more slender as they grow longer, indicated by exponent b in weight-length relationship

Life history where only present year queens overwinter while all males, workers, and old queens die by first snow cover

The study of bee foraging behavior, including diet breadth, sociality, body size, and foraging distances in relation to floral resource availability.

Visual and vocal displays by nestlings to communicate their status of need and obtain resources from parents

Direct relationship between body size and reproductive output in mayflies

Semi-fossorial marmots using the same burrow entrances, indicating social association

Post-burial behaviors including shaving fur, rounding carcasses, and secreting antimicrobial exudate

The process by which bumble bee colonies grow in size throughout the foraging season

Population growth from small ancestral populations leading to characteristic genetic signatures

The transition from egg stage to juvenile stage and the factors affecting success of this transition

Physiological mechanisms allowing insects to survive and function despite exposure to ethanol, including alcohol dehydrogenase enzyme activity

A female mates with a male other than the territorial male of her family group, increasing frequency when snow cover is reduced

A life-history trait that buffers marmots against climate change by allowing them to escape changes in climate and effectively expand their ecological niches

Ground squirrels metabolize fat reserves built up during previous foraging seasons, with high amounts of foraging ensuring enough fat storage levels for fitness and survival

Complex life cycle involving multiple spore stages that infect plant hosts in different families

The interaction between a host organism and its pathogen, where genes in the host that express resistance and genes in the pathogen that express virulence are highly specific and correspond to each ot...

Movement of individuals into a population from external sources

Cannibalism occurring between different age cohorts, where older individuals consume younger individuals of the same species

Social learning mechanism where individuals are attracted to a location simply by others being present, rather than learning specific manipulative tasks

Reduction in metabolic rate that can be active or passive

The ability to recognize who is singing important for territorial defense and mate attraction

The influence of nearby conspecifics on an individual's fitness components, mediated by local density and composition

The process by which Red-naped Sapsuckers choose trees for nesting sites
