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
hypothesis

hibernation-ageing hypothesis

The hypothesis that ageing is suspended during hibernation, whereby species engaging in torpor periodically suspend ageing and thus live longer than predicted based on body size alone

general ecology1 paper
measurement

hiding time

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

population ecology1 paper
method type

hierarchical clustering

Statistical technique to classify studied locations into groups based on measured variables such that similar locations are placed in the same group

process

hillslope-riparian gradient

Spatial gradient from hillslope to riparian zone representing changes in hydrology, geochemistry, and proximity to stream

process

homogenizing selection

Community assembly process where environmental conditions favor similar microbial communities, resulting in communities more similar than expected by chance

community 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

The convergent set of floral traits (red color, tubular morphology, dilute nectar) expected to evolve in flowers adapted for hummingbird pollination

community ecology1 paper
theory

humped-back model

A model suggesting that plant diversity peaks at intermediate productivity, is low at high productivity where few species dominate available resources, and is low at low productivity where few species...

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
