Concepts

The probability of detecting a species given that it is present at a site

Consumption of dead organic matter by organisms, particularly caddisfly larvae feeding on detritus

Functional guild of macroinvertebrates that break down dead organic material, contributing to nutrient cycling in aquatic ecosystems

A tool that uses paired statements about morphological characteristics to systematically identify organisms through a series of either/or choices

Daily patterns in organism behavior, with some mayfly species showing increased drift activity at night to minimize exposure to visual predators

Differential prey use based on habitat type, with fairy shrimp comprising majority of diet in temporary ponds

Genes that show significantly different expression levels between treatment conditions

Subsurface conditions where chemical transport is limited to diffusion rather than advection, creating oxygen-depleted anoxic conditions

The ability to extract nutrients from consumed food, measured here by frass mass relative to provision mass and extent of pollen grain digestion

Raster representation of terrain elevation used to derive topographic attributes like slope and aspect

Spatial sampling design measuring wildlife responses at increasing distances from disturbance sources

Decrease in compositional similarity between communities with increasing geographic distance or environmental separation

The location of extrafloral nectaries relative to plant reproductive structures acts to distract flower-damaging ants or other visitors from flowers, and consequently pollinators as well

Mathematical moments describing trait distributions including mean, variance, skew and kurtosis that characterize central tendency, spread, asymmetry and tail behavior

The hypothesis that species that are competitively dominant have reduced ability to discover new resources quickly

Predicts that dominant species may be more specialized on particular resources than subordinates, allowing subordinate species to coexist by better capitalizing on unused resources.

Biogeochemical model that accounts for moisture-dependent activation and dormancy of distinct microbial communities at different effective saturations

A habitat not well suited for survival and reproduction that animals are attracted to for foraging if the threat of vehicles is not recognized

Benefits that humans derive from ecosystem processes, including pollination, pest control, and decomposition

Rate at which turbulent kinetic energy is converted to heat, used as quantitative measure of atmospheric turbulence intensity

Loss of cellular electrolytes through compromised cell membranes, used as indicator of heat stress damage

Use of electrical current to temporarily stun aquatic organisms for collection without physical substrate disturbance

Differential responses of organisms to different stereoisomeric forms of the same chemical compound

Process-based framework for understanding drivers of thermal offsets and thermal coupling strengths in leaves based on energy budget parameters

The principle asserting an inverse relationship between local population density and average metabolic rate of individuals in a species

Degree of environmental stress affecting survival and reproduction, differing between elevational sites

The ability of young trees to successfully establish and survive in a given environment

Predator recognition abilities that do not require prior learning or experience with predators but are based on innate or genetically-determined responses

Competition through depletion of shared resources without direct interaction

Behavioral tendency to investigate novel environments, measured through open-field tests

Biogeographic classification of species based on their broader distributional affinities and evolutionary origins
