measurement

handling time

population ecology1 paper
measurement

handling time

The duration a pollinator spends foraging on each flower, calculated by dividing total foraging bout duration by number of flowers visited

population ecology1 paper
measurement

harvest exposure

The degree to which wildlife populations are subjected to potential harvest mortality based on spatial overlap with legal hunting areas and temporal overlap with hunting seasons

population ecology1 paper
phenomenon

heat hardening response

population ecology1 paper
measurement

herbivore density

Abundance and biomass of herbivorous insects, expected to decrease at higher elevations due to temperature constraints

population ecology1 paper
phenomenon

herd immunity

population ecology1 paper
process

hibernation

A life-history trait that buffers marmots against climate change by allowing them to escape changes in climate and effectively expand their ecological niches

population ecology1 paper
process

hibernation energetics

Ground squirrels metabolize fat reserves built up during previous foraging seasons, with high amounts of foraging ensuring enough fat storage levels for fitness and survival

population ecology1 paper
measurement

hiding time

Duration that an animal remains concealed in a refuge after fleeing from a predator threat

population ecology1 paper
theory

homophily

The tendency for similar individuals to associate and form ties, thus limiting their social worlds and altering the information they receive and the interactions they experience

population ecology1 paper
process

host alternation

Complex life cycle involving multiple spore stages that infect plant hosts in different families

population ecology1 paper
phenomenon

host preferences

population ecology1 paper
process

host-pathogen interaction

The interaction between a host organism and its pathogen, where genes in the host that express resistance and genes in the pathogen that express virulence are highly specific and correspond to each ot...

population ecology1 paper
framework

hunting season regulations

Legal frameworks governing when, where, and how many game animals can be harvested including bag limits, possession limits, season length and timing, and area closures

population ecology1 paper
phenomenon

idiobiont parasitoid

Ectoparasitoids whose eggs are oviposited outside of the host, often in enclosed environments, with host development ceasing upon parasitism via paralysis

population ecology1 paper
process

immigration

Movement of individuals into a population from external sources

population ecology1 paper
metric

individual deviation

The difference in days between an individual's peak bloom date and the population's peak bloom date at the site

population ecology1 paper
phenomenon

infanticide

The killing of infants by conspecifics other than the parents

population ecology1 paper
measurement

innovation success

successful manipulation of puzzle box to obtain food reward by opening either lid or door

population ecology1 paper
measurement

insect biomass

Total dry weight of insects captured, used as proxy for abundance and population size

population ecology1 paper
metric

instantaneous mortality rate

A measure of per-capita mortality rate calculated as the natural logarithm of survival over time

population ecology1 paper
process

inter-cohort cannibalism

Cannibalism occurring between different age cohorts, where older individuals consume younger individuals of the same species

phenomenon

lek

Traditional breeding display ground used by sage-grouse where males gather to perform courtship displays

population ecology1 paper
measurement

lek

measurement

lek inactivity

population ecology1 paper
framework

life history stages

Discrete developmental periods in marmots separated by annual hibernation: pups (<1 year), yearlings (1 year), and adults (≥2 years)

population ecology1 paper
framework

life history traits

Ecological and life history traits that determine a bird species response to extreme meteorological events and vary with elevation

population ecology1 paper
process

local enhancement

Social learning mechanism where individuals are attracted to a location simply by others being present, rather than learning specific manipulative tasks

population ecology1 paper
measurement

long-term success

Survival and performance of transplanted vegetation measured years after initial establishment

population ecology1 paper
phenomenon

lunar cycle foraging behavior

Changes in animal foraging activity and risk-taking behavior in response to different moon phases and associated predation risk

population ecology1 paper
phenomenon

male desertion

Males leaving the brood first, leaving their mates as sole caretakers of the larvae

population ecology1 paper
measurement

male emergence timing

The timing of male bee emergence relative to females, used as an indicator of social breeding strategy and brood structure.

Influence of maternal identity on offspring growth through burrow location, maternal investment, and genetics

population ecology1 paper
phenomenon

maternal stress effects

Impact of maternal stress levels on offspring survival and development, potentially with intergenerational effects
