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
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
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
hiding time
Duration that an animal remains concealed in a refuge after fleeing from a predator threat
hierarchical clustering
Statistical technique to classify studied locations into groups based on measured variables such that similar locations are placed in the same group
hierarchy theory
hillslope-riparian gradient
Spatial gradient from hillslope to riparian zone representing changes in hydrology, geochemistry, and proximity to stream
historical vicariance
homogenizing selection
Community assembly process where environmental conditions favor similar microbial communities, resulting in communities more similar than expected by chance
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
honeydew
host alternation
Complex life cycle involving multiple spore stages that infect plant hosts in different families
host manipulation
host preferences
host range expansion
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...
host-vector interaction
human footprint
Spatial extent of human habituation effects or the behavioral footprint of anthropogenic impacts
hummingbird flower syndrome
The convergent set of floral traits (red color, tubular morphology, dilute nectar) expected to evolve in flowers adapted for hummingbird pollination
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...
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
hybrid modeling
Approach combining process-based physical models with empirical statistical relationships
hybrid predictive modeling
Modeling approach that integrates machine learning with meteorological data, remote sensing, and either flux measurements or mechanistic model outputs
hydraulic failure
hydraulic refugia
Areas of low velocity and reduced hydraulic stress that provide shelter for aquatic organisms from strong flow forces
hydrograph extremes
Peaks and troughs in groundwater level time series representing maximum and minimum water levels
hydrologic processes
Water movement and chemistry dynamics that maintain fen ecosystems and support specialized plant communities
hydrological conditions
Water-related environmental factors including humidity, rainfall, snow cover, and soil moisture that affect disease transmission and host physiology
hygroscopic growth
hyper-resolution
Spatial resolutions of the order of a few hundred meters, as defined in this work
hyperparameter optimization
hyperspectral imaging
Remote sensing technique using wavelengths from 400-1000 nanometers to capture spectral signatures
hypothalamic-pituitary-gonadal (HPG) axis
ice water content
Mass of ice particles per unit volume of air, typically expressed in kg m⁻³
ideal free distribution
idiobiont parasitoid
Ectoparasitoids whose eggs are oviposited outside of the host, often in enclosed environments, with host development ceasing upon parasitism via paralysis
ill-structured task
immersion mode
immigration
Movement of individuals into a population from external sources
immunosuppression
Reduction in immune system function often caused by parasites or stress
implement house design
in-person UREs
incipient fasting
The hypothesis that observed declines in excretion rates over time are due to cessation of feeding rather than other factors
inclusive fitness theory
Hamilton's theory that fitness should be stripped of all components which can be considered as due to the individual's social environment, leaving the fitness he would express if not exposed to any of...
incursion year
Years when VS cases are seen in states just a few months prior to outbreaks being recognized
individual deviation
The difference in days between an individual's peak bloom date and the population's peak bloom date at the site
indole
indole emission
induced defenses
induced morphological defenses
Morphological defenses that are induced by the presence of predators, such as longer caudal filaments in mayflies exposed to fish predators
