Concepts

Ability of organisms to compensate for poor early-life conditions through increased feeding or altered resource allocation later in life

Hypothesis that highly aroused animals produce nonlinear vocalizations because they lose control of their larynx over vocal fold production apparatus

Nature-based tourism activities that can provide conservation benefits but may also impact wildlife behavior through human presence

Ecological research projects that follow individuals or systems over extended periods, often spanning decades

Behavioral and physiological mechanisms whereby group-living animals share body heat to reduce thermoregulatory costs

The distance between the anus and the genital papilla, used as a non-invasive measure of prenatal exposure to sex steroid hormones

Internal biological timing system that maintains rhythmicity in a wide range of behavioral, physiological, and metabolic processes

Physiological and behavioral adaptations to minimize energy expenditure

Maximum running speed of an individual measured during chase trials

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

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

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

Scientific discipline focused on protecting and preserving species and ecosystems

Specialization of left and right brain hemispheres to carry out specific activities, with right hemisphere processing threats and left hemisphere processing conspecifics
