Direct relationship between body size and reproductive output in mayflies
bonanza resource
A valuable and unpredictable prize (carrion) that must be defended from an assortment of organisms
boom-and-bust dynamics
Large fluctuations in damage levels driven by interactions between warming and precipitation variability
boundary layer mixing
Vertical mixing of air in the atmospheric boundary layer that affects aerosol concentrations and vertical distribution
bounding box ratio
A dimensional ratio calculated from minimum bounding rectangles to quantify the shape characteristics of pond polygons
braided stream facies
Sedimentary facies characteristic of braided river systems with multiple channels and bars
broken-stick model
Statistical model used to determine the number of principal components to retain, setting threshold above which a component explains more variation than expected by chance alone
brood cell completion
brood quality
Measures of brood fitness including larval number, weight, and production efficiency
brown food web
The component of food webs based on detrital energy pathways as opposed to primary production
browsing
buffering
buffering hypothesis
Hypothesis that presence of active social support systems provides aid to focal individuals and creates buffer against stressors
built environment microbiology
Study of microbial communities and processes in constructed habitats and structures
bull's-eye pattern
A spatial pattern of rapid exhumation concentrated in a central zone with decreasing rates toward the periphery
burrow sharing
Semi-fossorial marmots using the same burrow entrances, indicating social association

calcium common ion effect
caldera volcanism
caloric restriction
camera trap image classification
Automated identification of species from camera trap photographs using machine learning
canopy height model
Digital representation of forest canopy height derived from remote sensing data

Process by which tree canopies intercept and reduce throughfall of precipitation to surface soils
canopy light penetration
The amount of sunlight reaching the forest floor through tree canopy, affected by crown thinning and leaf flushing
capillary fringe
capital accumulation
The economic process by which wealth is concentrated through industrial extraction and trade networks
captive breeding
Conservation strategy to preserve threatened or critically endangered species through maintaining reproductive populations in captivity
capture-recapture
An ecological technique that relies on randomly choosing a sample of recorded syllables and then 'recapturing' some of those syllables in successive samples to estimate total repertoire size
carbohydrate-active enzymes
Enzymes involved in the synthesis, modification, and degradation of carbohydrates including polysaccharides
carbon budget model
Integrative model combining photosynthesis, respiration, and total nonstructural carbohydrate measurements to quantify carbon allocation patterns

Accumulated shortage of carbon resources in plants that can influence future phenological timing
carbon limitation
Water acts as a limiting factor for both decomposition of organic matter and net carbon assimilation
carbon loss rate per degree per year
carbon oxidation
carbon spectroscopy
Spectroscopic techniques including NEXAFS and FTIR used to characterize the functional group composition and chemical structure of organic carbon
carbon use efficiency
The proportion of carbon taken up by microorganisms that is converted to biomass rather than respired as CO2
carcass maintenance behaviors
Post-burial behaviors including shaving fur, rounding carcasses, and secreting antimicrobial exudate
cardenolide
carrier frequency
The dominant frequency component of acoustic signals, measured as the highest peak frequency from FFT analysis
carry-over effects
Effects of herbivory and pollination that persist from one growing season to the next
cascade barriers
Natural waterfall barriers that create transitions between fishless upstream reaches and fish-containing downstream reaches
cash rent premiums
The difference between cash rents for irrigated versus non-irrigated land in the same area, used to estimate the value of water for irrigation
caste distribution function
The range of worker sizes within colonies, also called worker polymorphism
catch per unit effort
Standardized measure of abundance calculated as number of individuals caught per unit of sampling time or effort
categorical forecast verification
Assessment of forecast skill for predicting occurrence of events within defined categories using contingency table analysis
