ecology of fear
The concept that predator-prey interactions extend beyond direct predation and can influence prey behavior and habitat use through perceived predation risk
ecosystem-based management
eddy covariance
Methodology for measuring turbulent fluxes using high-frequency measurements of vertical wind velocity and scalar concentrations
effect sizes
electivity index
A measure comparing the proportion of prey in predator diet to proportion in environment to detect selection or avoidance
elevation isotopic lapse rate
The systematic change in isotopic composition of precipitation with elevation due to progressive rainout and temperature effects
energy conservation
Physiological and behavioral adaptations to minimize energy expenditure
energy flux residual
energy tradeoffs
Breeding birds must balance energy allocation between reproduction and survival, with parasites forcing energy towards immune response rather than reproductive traits
epidemic dynamics
The temporal progression and patterns of disease spread through host populations
expectancy-value theory
extracellular enzyme activity
extracellular enzyme activity
Activity of enzymes secreted by soil microorganisms that catalyze decomposition of organic matter and provide assimilable carbon and nitrogen compounds
fSCA
falling limb
fixation indices
F-statistics (FIS, FST, FIT) measuring genetic differentiation and inbreeding at different hierarchical levels
floral scent
forest composition
foresummer drought sensitivity
The slope of peak NDVI as a linear function of the June Palmer Drought Severity Index, representing plant productivity responses to early growing season drought conditions
fraction modern (Fm)
gas chromatography-mass spectrometry
Analytical technique combining gas chromatography separation with mass spectrometry identification for analyzing volatile compounds
gas exchange velocities
genetic constraints
Limitations on evolutionary divergence imposed by genetic architecture and patterns of genetic covariation
genetic rescue
Improvement in population fitness through the introduction of new genetic material
genome annotation
Computational identification and labeling of genes and other functional elements in genome sequences
glacial advances
Forward movement of ice sheets that leave behind terminal moraines and other glacial deposits
group size effects
Changes in social behavior and group dynamics that result from variation in the number of individuals in a social group
gustnadoes
habitat fragmentation
Fragmented vegetation structure affecting bird population abundances and foraging opportunities
herbarium collections
Preserved plant specimens that are picked in the field, pressed flat, dried and attached to archival-grade paper with relevant information recorded, then stored in climate-controlled cabinets
heterozygote deficiency
Lower than expected frequency of heterozygous genotypes in a population
honeydew production
The excretion of sugar-rich liquid waste by herbivorous hemipterans feeding on plant sap
host selection
hybrid breakdown
Reduced fitness in F2 hybrids compared to F1 hybrids, often attributed to genetic incompatibilities between nuclear genes
hyper-resolution modeling
High spatial resolution climate modeling at sub-kilometer scales for hydrological applications
hysteresis
Different trajectory of C-Q relationships during rising and falling limbs of hydrographs that indicate differences in timing of hydrological response from surface and subsurface compartments
immune response
Physiological responses of the immune system to pathogens, trauma, stress and inflammation
immunity
inbreeding coefficient
Measure of the level of inbreeding within a population, with values close to 1.0 indicating high levels of inbreeding
individual tree detection
Automated algorithms for identifying and delineating individual trees from LiDAR point cloud data
individual-based model
Computational model that simulates individual organisms and their life histories to understand population-level patterns
inorganic phosphorus
irrigation
juvenile fitness
Measures of early-life performance that may predict later survival and reproductive success
last interglacial period
The most recent period in Earth's history (~116-130 ka) when temperatures were persistently warmer than today, specifically the Eemian period at 125 ka
leaf number
lethal sampling
Sampling methods that result in the death of collected organisms, potentially affecting population abundance and community structure
light gradient
Environmental gradient of light availability from open sun through intermediate shade to deep shade habitats
limits of detection
litter sex composition
The proportion of male versus female offspring in a litter affecting prenatal hormone exposure
