Concepts

Process where trees shift their root water uptake from topsoil towards subsoil to sustain transpiration rates when shallow soil moisture declines

Variation in the strength or direction of ecological effects depending on environmental conditions or organism characteristics

Selective consumption behavior of invertebrates feeding on different types of organic detritus

Soil electrical conductivity measured via electrical resistivity tomography to estimate soil moisture and subsurface properties

The flow of energy through ecological systems, measured as invertebrate biomass transfer from terrestrial to aquatic environments

Meteorological events that are rare for a particular place or time of year and can have major ecological impacts

Sequential developmental stages of individual flowers progressing through male phases (M1, M2), inter-phase, and female phase

Geophysical method using electromagnetic waves to measure subsurface properties including snow density through travel-time analysis

Restoration of native plant communities in disturbed areas through environmental manipulation

Transfer of genetic material between organisms through mechanisms other than vertical inheritance

Addition of new individuals to insect populations through successful reproduction and development

Variation in behavioral expression within individuals across time or contexts

The cycling of iron between different chemical forms including soluble ferrous iron (Fe(II)) and ferric iron (Fe(III)) based on oxygen availability

Persistent ecological impacts that continue after the original disturbance or activity has ceased

Chemical composition of plant litter that determines its decomposability, typically characterized by C:N ratios and lignin content

Mathematical model describing sigmoidal population growth with carrying capacity constraints

Maximum temperature of warmest month, capturing seasonality in contrast to average annual temperatures

A network's sensitivity to simulated extinction of plants or pollinators, measured as secondary extinction cascades

Ratio of neutrophil to lymphocyte white blood cell counts used as a measure of immune response activity

Low nutrient conditions that select for microorganisms adapted to low substrate availability

Atmospheric turbulence generated by airflow over mountainous terrain leading to enhanced mixing and modified precipitation processes

Evolutionary divergence time between species measured in millions of years, calculated from molecular phylogenetic reconstructions

Genetic differentiation between populations across the genome, measured by allele frequency differences and population genetic statistics like FST

Scaled measure of how population growth rate responds to changes in environmental drivers

The average number of offspring produced by a typical individual during its life, calculated as the product of offspring number and survival probability
