measurement

cohort duration

The number of elapsed days from the estimated starting date to ending date of a developmental cohort

measurement

collaboration

When animals work together to take over existing social groups and oust the dominant males, as seen in banded mongooses

theory

colonization cycle

Theoretical framework suggesting that upstream flight of stream insect adults is necessary to maintain larval populations in upstream reaches that might otherwise be depleted by downstream drift of la...

measurement

colonization rate

The rate at which empty sites are reoccupied by dispersing individuals

process

colony buildup

The process by which bumble bee colonies grow in size throughout the foraging season

population ecology1 paper
theory

compensatory mortality

The ecological principle that removing individuals may not reduce population size if sampling removes individuals that would have died anyway

metric

cumulative adversity index

Quantitative measure that sums multiple adversity measures experienced during early life to assess overall adversity burden

population ecology1 paper
theory

cumulative reproductive cost

The hypothesis that reproductive costs accumulate over an individual's reproductive life span, with long-term costs occurring alongside or instead of short-term costs

process

demographic expansion

Population growth from small ancestral populations leading to characteristic genetic signatures

process

density-dependence

population ecology1 paper
measurement

developmental rate

The speed at which organisms progress through life stages, influenced by temperature and other environmental factors

population ecology1 paper
hypothesis

developmental time constraints

Limited time available for larval development before habitat drying selects for aggressive behavior

measurement

dipteran seasonal abundance

Patterns of fly abundance and biomass across the growing season

population ecology1 paper
measurement

disease resistance

The ability of a host organism to resist infection or reduce disease severity when exposed to pathogens

population ecology1 paper
hypothesis

earlier-larger hypothesis

Hypothesis that increased food availability should lead to earlier emergence of larger adults

population ecology1 paper
phenomenon

early life adversity

Adverse experiences during the period between conception and sexual maturity that can impact later life health and survival

population ecology1 paper
theory

ecology of fear

A phenomenon where paedomorphic salamanders are more successful at cannibalizing smaller larvae than metamorphs in ponds with high numbers of paedomorphs

population ecology1 paper
process

egg-juvenile recruitment

The transition from egg stage to juvenile stage and the factors affecting success of this transition

metric

elasticity

Proportional change in λs resulting from a proportional change in the mean or standard deviation of a single vital rate

population ecology1 paper
theory

energy budget constraints

The hypothesis that energy budgets rather than time budgets constrain marmot activity patterns

population ecology1 paper
theory

equilibrium stability

Analysis of whether population equilibria are locally stable or unstable based on eigenvalues of the Jacobian matrix

population ecology1 paper
process

establishment failure
