Concepts

Exposure to ultraviolet radiation from natural sunlight

Proportion of time spent in relaxed behaviors (foraging, preening, vocalizing) following acoustic stimulus presentation

The ratio of the number of subpopulation diseased plants to the total number of plants in each 25-m² subpopulation

A latent variable representing overall environmental suitability that affects multiple demographic processes simultaneously

The behavioral initiation of flight activity in response to environmental conditions, particularly temperature

Metrics that sum up accumulated change over time, reducing historical processes to single data points

Rate of forest growth and biomass accumulation, often measured through tree ring widths or forest inventory data

Using heart rate measurements as an indirect indicator of metabolic rate and energy expenditure in free-ranging animals

The innermost layer of the integument adjacent to the embryo sac in ovules, characterized by hypertrophied cells in some species

Student perceptions of the quality of relationships and support received from research mentors

Rate of energy expenditure or metabolic activity in plant species

Fat content and biomass composition of ant nests as food resources for bears

A measure of asymmetry in the distribution of phenological activity timing, quantified as the Fisher-Pearson standardized third-moment coefficient

Students' sense of being connected to and comfortable with their research groups, programs, or broader scientific communities

An important factor for terrestrial amphibians due to their moist and permeable skin which allows for exchange of water, ions, and gasses in terrestrial habitats

The relative efficiency of the eye to be stimulated and detect light or other signals, as a function of the wavelength of the signal

The overall health of trees, assessed qualitatively by visually rating tree crowns or quantitatively by comparing growth rates and potential to succumb to insect attack

Difference in means of the distributions when the difference in means is smaller, the stimulus is more uncertain and the state of the world is more ambiguous

Dispersal ability or mobility of an organism

Body mass per unit wing area, calculated as mg mm⁻² and related to flight energetics and thermoregulation
