Concepts

Physiological and behavioral adaptations to minimize energy expenditure

Breeding birds must balance energy allocation between reproduction and survival, with parasites forcing energy towards immune response rather than reproductive traits

Physiological responses of the immune system to pathogens, trauma, stress and inflammation

Environmental gradient of light availability from open sun through intermediate shade to deep shade habitats

Maximum running speed of an individual measured during chase trials

Theory stating that foragers will leave a patch after the quality of the patch drops below the average quality of the overall habitat

Study of how organisms obtain and use nutrients and how nutrition affects fitness

An individual's development from egg to adult

The proportion of variance in a trait that is explained by individual identity, indicating consistency of individual differences over time and across situations

Sodium being a limiting nutrient in natural systems, affecting organism behavior and ecosystem interactions

The ability of bumble bees to regulate internal body temperature through muscle contraction

Situations where time spent on one activity reduces time available for other activities

Requirement for extended cold treatment to trigger flowering in some plant species

A relationship between plumage coloration and climate variation, predicting that darker coloration due to pigmentation occurred in warmer, more humid tropical regions while lighter colors occurred in ...

A measure of how well acoustic signals maintain their structure when transmitted through different environments

A brief but generalized sickness syndrome triggered by bacterial infections and LPS injection

Vegetative damage leading to temporary or permanent defoliation and/or aboveground stem loss

A series of sites of different ages since disturbance used to infer temporal changes in ecological processes

Study of how cognitive mechanisms govern decision-making by floral visitors and shape pollination and plant fitness

Scientific discipline focused on protecting and preserving species and ecosystems

Benefits that humans derive from ecosystem processes, including pollination, pest control, and decomposition

Differential responses of organisms to different stereoisomeric forms of the same chemical compound

Degree of environmental stress affecting survival and reproduction, differing between elevational sites
