Concepts

Absolute abundance of bacteria measured as colony forming units per unit leaf mass

Ungulate feeding method where animals scrape off and eat chlorophyll-filled bark and cambium using their lower incisors

Annual change in cross-sectional area of tree stem measured from tree ring widths

The flux of weathering-derived cations (Ca, Mg, Na, K) from subsurface to surface waters

Physical processes that create fractures in subsurface bedrock, enabling geogenic elements to enter rivers and biogeochemical cycles

Integrated characterization of subsurface, surface, and vegetation properties spanning the full vertical profile

Arthropods collected in bee bowl traps that are not being examined by a study and are not collected or recorded in any data set

The study of bee foraging behavior, including diet breadth, sociality, body size, and foraging distances in relation to floral resource availability.

Visual and vocal displays by nestlings to communicate their status of need and obtain resources from parents

A technique that graphs the number of songs recorded versus the number of song types and uses curve equations to estimate maximum repertoire size when the curve reaches an asymptote

Quantitative measurement of presence/absence, frequency, and/or duration of specific behaviors

The ability of animals to compensate for disturbance-driven behavioral changes through unknown mechanisms

Having superior aggressive behaviors that deter other ants, measured through direct encounters

Proportion of time spent in relaxed behaviors (foraging, preening, vocalizing) following acoustic stimulus presentation

proportion of successful behaviors when interacting with apparatus

Diversity of soil microorganisms including bacteria, fungi, archaea, and protist communities

Life-history strategy that reduces variance in fitness at the expense of lower mean fitness by producing multiple phenotypes

plants invest moderately in attracting pollinators early in season and creating flowers to hedge bets on abiotic resource conditions later in the season

Between-plot flowering-time diversity component representing differences in phenological timing among plots

Metric calculated to determine deviation from null mean nearest taxon distance, used to identify whether deterministic or stochastic processes shape community composition

A flowering pattern characterized by two distinct peaks separated by a valley of lower abundance

Anaerobic biological treatment using organic substrate and bacteria to reduce sulfate and precipitate metals from acid mine drainage

The postulated cascade of biodiversity loss that would occur in aspen and willow ecosystems if red-naped sapsuckers were removed

Systematic observation and assessment of biological diversity over time to detect changes in species populations, community composition, and ecosystem health

Study of energy flow and energy dynamics in biological systems

Chemical and physical properties of sediments including pH, bulk density, organic matter content, dissolved nutrients, and moisture content that influence microbial processes.

Reservoir of biogeochemical capacity available as environmental conditions change, defined by genetic capabilities rather than instantaneous activity

Interconnected set of microbially-mediated reactions including aerobic respiration, denitrification, iron reduction, and sulfate reduction

Communities of cyanobacteria, lichens, and mosses that live on soil surfaces and contribute to soil stability and fertility

Process of confirming that a physiological assay accurately reflects the biological process it claims to measure through controlled experiments

Disturbance of sedimentary deposits by living organisms, in this case soil mixing by ant tunneling activities

Differential outcomes based on position within family birth sequence

Comprehensive collection method attempting to document all species present at a site regardless of abundance
