measurement

small mammal abundance

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

measurement

temporal demographic correlation

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

Growth of new aspen trees through sexual reproduction (seeds) or asexual reproduction (suckering from root systems)

population ecology2 papers
process

asymptotic growth

Growth pattern characterized by an initial period of mass gain followed by stabilization before hibernation entry

measurement

behavioral diversity

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

measurement

boldness

theory

demographic compensation

Population response where decreases in fitness due to other factors are offset by increases in another demographic parameter

measurement

development rates

phenomenon

diel periodicity

hypothesis

floral size-seed correlation

The hypothesis that larger flowers produce more seeds due to greater resource allocation or pollinator attraction

measurement

generation time

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

population ecology2 papers
phenomenon

group living

Social organization where individuals aggregate in groups, potentially providing antipredator benefits through collective vigilance and dilution effects
