process

animal communication

Mechanisms used by individuals to convey different cues to others, including color, vocal cues, body language, and biofluorescence

general ecology3 papers
phenomenon

case grazing

Behavior where caddisfly larvae consume material from their own or others' protective cases

community ecology3 papers
measurement

coarse particulate organic matter

Organic matter particles larger than 1 mm, including intact leaves and larger detrital fragments

biogeochemistry3 papers
phenomenon

diel vertical migration

Daily behavioral pattern where aquatic organisms move vertically in the water column, typically showing different activity levels during day versus night periods

community ecology3 papers
process

drift phase

hydrology3 papers
metric

electivity index

A measure comparing the proportion of prey in predator diet to proportion in environment to detect selection or avoidance

methodological3 papers
measurement

mass-specific excretion rate

the rate of nutrient excretion per unit body mass of an organism

biogeochemistry3 papers
framework

non-additive effects

Combined impact of multiple predators differs from the sum of their individual effects, can be greater or less than additive

community ecology3 papers
process

positive feedback loop

Mechanism where state and behavior mutually reinforce each other, measured as positive correlation between individual intercept and slope in random regression models.

population ecology3 papers
model type

principal component analysis

Statistical method used to identify the structuring factors driving life-history variation and to detect slow-fast continuum patterns

methodological3 papers
metric

sampling efficiency

Measure of how effectively a sampling method captures target organisms relative to processing time and effort

methodological3 papers
process

terrestrial subsidies

Input of terrestrial invertebrates into aquatic food webs providing energy to aquatic predators

community ecology3 papers
theory

threshold elemental ratios

The hypothesis that disposing of excess dietary nutrients imposes a growth cost on organisms, creating hump-shaped relationships with diet stoichiometry

biogeochemistry3 papers
measurement

EPT taxa

Ephemeroptera, Plecoptera, and Trichoptera orders used as indicators of aquatic ecosystem health

community ecology2 papers
measurement

ash-free dry mass

Standard measure of organic biomass determined by ashing samples to remove inorganic material

methodological2 papers
phenomenon

beaver pond morphology

Physical structure and arrangement of beaver ponds, specifically comparing single isolated ponds versus terraced series of connected ponds

landscape2 papers
measurement

benthic organic matter

Organic material found in pond sediments that serves as nutrient storage compartment

biogeochemistry2 papers
theory

best of a bad lot mechanism

Paedomorphosis becomes the preferred life strategy when growing conditions such as prey abundance, water temperature, and population density are poor, so individuals opt to cut losses and become sexua...

evolution2 papers
process

bioaccumulation

The accumulation of substances like sodium in organisms through their food chain, allowing carnivores to obtain adequate salt from prey

biogeochemistry2 papers
process

biofilm succession

The sequential development of microbial communities on substrates following disturbance

community ecology2 papers
theory

demographic compensation

Population response where decreases in fitness due to other factors are offset by increases in another demographic parameter

population ecology2 papers
framework

depletion sampling

Population estimation method using repeated sampling to remove individuals and estimate total abundance from decline curve

population ecology2 papers
process

detritivory

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

community ecology2 papers
process

detritus shredders

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

community ecology2 papers
phenomenon

diel periodicity

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

population ecology2 papers
phenomenon

dietary specialization

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

measurement

hydrological regime

Patterns of stream flow including magnitude, timing, and duration of high and low flow periods

hydrology2 papers
process

intraguild predation

Asymmetric intraguild predation (IGP) between caddisflies where larger, faster-growing species prey on smaller competitors
