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

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

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

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

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

Behavioral tendency to investigate novel environments, measured through open-field tests

The mean age of females when they lay eggs or give birth, calculated as the inverse of the sum of elasticities of population growth rate to changes in fecundities

The angle between the paths of predator and prey to the prey's refuge, expressing degree to which prey must run towards an approaching predator

When any social group contains 2 or more males with neither male forced to leave the group because of conflict

When animals prefer to associate with certain individuals over others within a group

Classification of female reproductive phase as gestation/lactation or post-reproductive/pre-hibernation

Linear distance along stream between upper and lower boundaries of breeding territory
