The distance beyond which the positive effects of habitat features on species richness and abundance become negligible

Nonlinear responses where rates change dramatically at specific density values

Type of reverse fault with low dip angle where older rocks are pushed over younger rocks due to compressive stress

Landscape variables including elevation, slope, aspect, and wetness indices that influence tree growth

Second-order derivative of elevation used as proxy for convergent vs divergent topography affecting soil accumulation

Concentration of water flow toward convergent topographic zones where slopes flatten and sparse conifer forests grow

The difference in elevation between high and low points in a landscape

Statistical removal of individuals from networks to evaluate the effect of removing an individual of a specific age-sex category from each social group

State of reduced metabolism and body temperature that hummingbirds enter to conserve energy when insufficient energy is available

Measure of organic carbon content in sediments, used as indicator of available carbon for microbial metabolism

The attachment and retention of trace metals to sediment particles, which has been the topic of numerous studies investigating rates of cation exchange on clay minerals and particle-size variability

Competing advantages where hermaphrodites have higher resource demands but also reproductive assurance through self-fertilization, while females allocate resources more efficiently to seed production ...

The balance between exploiting benign habitats with strong biotic interactions versus stressful habitats with reduced competition

Weekly number of visitors used as a proxy for vehicle traffic volume on nearby roads

A type of range shift where the trailing edge of a species distribution contracts, losing habitat at the rear of the range

Functional categorization of traits as vegetative vs reproductive based on their role in plant physiology and reproduction

Plant traits modify the functional response parameters and distinguish among non-mutually exclusive effects of plant genotype

Proteins that regulate gene expression, including pluripotency factors like OCT4 and SOX2 that can affect aging processes.

The elapsed time carbon atoms spend in the soil, characterizing the age structure of output flux from the soil

The frequency an individual entered a baited trap, used as a measure of boldness

The establishment and growth of new trees to measurable size (>1cm DBH) in forest stands

The overall health of trees, assessed qualitatively by visually rating tree crowns or quantitatively by comparing growth rates and potential to succumb to insect attack
