Concepts

The distance at which an individual initiates moving away from an approaching humans, reflecting flightiness of an animal in response to a potential predator

Time allocation to scanning for predators versus other activities like foraging, measured through specific postures and head orientations

Quantifiable aspects of social behavior and social structure that can be subject to natural selection

Demographic rates including survival, growth, flowering probability, seed production, and germination that determine population dynamics

A measure of how successful a bird is at food acquisition, quantified through observations as foraging rate (number of forages divided by time observed)

Daily mass gain during critical post-emergence development period in juvenile mammals

Per-capita population growth rate λ calculated as the dominant eigenvalue of the projection matrix at equilibrium

Population parameter measuring the relative frequency of males and females, specifically operational sex ratio of flowering individuals

Probability of surviving the summer active season, measured by last sighting dates relative to seasonal cutoffs

Metabolites of stress hormones measured in fecal samples as a proxy for physiological stress levels

The measure of seed quality based on embryonic development and potential for successful germination

The organization of genetic variation within and among populations, reflecting patterns of gene flow, drift, and selection

The likelihood that an individual survives from one time period to the next

The equilibrium population size at which population growth rate equals zero

Body size when organisms transition from growth to reproduction, with important consequences for lifetime reproductive success

The degree to which an individual is integrated in their group based on the number of independent links to others in the group

The degree to which individuals in a population exhibit coordinated timing of nesting activity

Individual's reaction to a non-novel, risky situation

An aversion to novel stimuli, measured as latency to touch the puzzle box from stepping onto the platform

Proportional increase in body mass during the active growing season, calculated as August 15 body mass divided by June 1 body mass

The abundance or availability of resources in a given area

Relative number of small mammals detected through camera trap monitoring expressed as activity indices

The correlation between different demographic parameters (survival, reproduction, productivity) measured across the same time periods within a population

Population growth rate (λ) integrating all vital rate components equivalent to average fitness component across a lineage or population

A measure of the variety of behaviors an individual uses, calculated using Shannon index across different behavioral categories during problem-solving trials

Risk-taking behavior calculated from flight initiation distance to a simulated predator approach

The duration of continuous engagement in a particular behavioral activity

The number of flowering individuals of the same species in the local area during an individual's peak bloom

The probability of detecting a species given that it is present at a site

The ability to extract nutrients from consumed food, measured here by frass mass relative to provision mass and extent of pollen grain digestion
