Pattern of fire occurrence including frequency, intensity, and timing that shapes ecosystem dynamics

The proportion of cells undergoing division within a population

Categorization of invertebrates based on feeding mechanisms: collector-gatherers, grazers, predators, shredders, and suspension-feeders

Signals that meet criteria of stimulus-class specificity and contextual independence, where alarm calls are said to be functionally referential when there is tight association between predator type an...

The downward movement of water from surface water to groundwater, occurring through infiltration and percolation processes and declining under warming due to increased evapotranspiration

Winter survival strategy of some small mammals that may affect their vulnerability to avalanche disturbance depending on burrow depth and emergence timing

Signaling system where the signal reliably indicates the quality or quantity of rewards available to the receiver

Sugar composition of plant phloem sap which honeydew is derived from, potentially altered by temperature affecting ant recruitment or tending behavior

Theory that animals distribute themselves among habitat patches in proportion to resource availability, with high-quality patches becoming occupied first and animals moving to lower-quality patches as...

Proportion of individuals in a population showing signs of pathogen infection

A quantitative measure of uncertainty about an outcome of a draw from a probability distribution

Nutritional limitation during larval development that affects adult phenotype

Feeding behavior where insect larvae create tunnels within plant leaves between epidermal layers

Ecological research projects that follow individuals or systems over extended periods, often spanning decades

Species-specific selection for particular combinations of physical habitat characteristics like water depth, current velocity, and substrate size

Rate laws governing the chemical breakdown of primary minerals as functions of temperature, pH, and saturation state

Mountain ecosystem characterized by specific elevation, climate, and vegetation adapted to montane conditions

Grouping of individuals based on body shape rather than species-level identification due to field identification constraints

Morton's theory that physical behaviors and acoustic signals are associated, with aggressive behaviors linked to noisy, low-frequency sounds and submissive behaviors to higher-frequency pure tones

An aversion to novel stimuli, measured as latency to touch the puzzle box from stepping onto the platform

Number of nests per unit area, calculated by dividing number of nests in each habitat by total area

The range of resources or interaction partners utilized by a species, in this context referring to the diversity of flower visitors to a plant species

Vertical distribution of plant nutrient uptake from soil surface through saprolite to bedrock

Spread of disease between individuals through various mechanisms including spore dispersal

Geometric ground formations created by freeze-thaw processes in alpine environments

Radar systems that transmit and receive both horizontal and vertical polarizations to characterize particle shape, orientation, and microphysical properties

Temporal variation in precipitation patterns expressed as coefficient of variation in monthly precipitation over 5 years

Male-first flowering phenology where flowers function first as males then as females

Study of ecological effects of roads and traffic on natural systems

Suite of plant responses to shade including stem elongation, reduced branching, and accelerated flowering to compete for light

Behavioral and physiological mechanisms whereby group-living animals share body heat to reduce thermoregulatory costs

Transmission of parasites among individuals within social mammalian groups

Attenuation and degradation of sound over distance due to atmospheric absorption, ground attenuation, signal scattering, and deflection by layered surfaces

Some environments will be resource rich and produce a high amount of offspring (sources) while other environments will be resource low and produce a low amount of offspring (sinks)

Assumption that spatial differences in environmental conditions can predict temporal responses to environmental change

Analysis of carbon and nitrogen isotope ratios to determine trophic position and dietary composition
