Concepts

Areas of disproportionately high biogeochemical activity or export relative to surrounding landscape

Morphological differences in the same species across different geographic regions

A gradual change in a trait across an environmental gradient, where width is expected to be proportional to dispersal distance divided by square root of difference in selection between ends of the cli...

Differences in chromosome copy number among individuals, specifically diploid (two copies) versus triploid (three copies) chromosome sets

When previously adaptive traits become maladaptive due to rapid environmental change, such that organisms are attracted to resources that reduce their fitness

Reduced fitness in inbred individuals compared to outbred individuals due to expression of deleterious recessive alleles

Acoustic phenomena including subharmonics, biphonation, deterministic chaos, and warbles that occur when vocal production apparatus loses control

Temporary pond hydroperiod reduction that triggers behavioral and physiological responses in aquatic organisms

Territorial behavior including alarm and warning calls to protect midden from squirrels and other mammals, with territories ranging from 0.5 to 1 hectares defended through vocalizations and chasing

Fine particulate matter generated by vehicular traffic on unpaved roads that settles on plant surfaces

The tendency for flower foragers to visit a single flower species during foraging trips even when alternative rewarding species are available

The diversity in maximum life spans across mammalian species, ranging from months to over 200 years.

Social organization where related females remain together and males typically disperse

Complete or near-complete elimination of local populations due to environmental catastrophe

Effects of human recreational activities on wildlife communities through habitat alteration, disturbance, and behavioral changes

Rapid, synchronous mortality of aspen across large areas characterized by gradual sudden aspen decline associated with recent drought and temperature stress

Social ranking system based on agonistic interactions where some individuals consistently dominate others

The degree to which parasites show preference or restriction to particular host species rather than being generalist

Redox-stratified and temporally dynamic sediments in river corridors where biological processes mediate sulfur transformations

Food availability timing related to snow melt and vegetation growth potentially mismatched with juvenile foraging periods

Seasonal precipitation system occurring July-September in the central Rocky Mountains bringing significant rainfall to Colorado River headwater basins

The emission of visible light by organisms following the absorption of shorter wavelengths of light

Geographic patterns in biodiversity and chemical diversity across latitudinal and environmental gradients

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

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

Variation in behavioral expression within individuals across time or contexts

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

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

Differential behavioral responses based on whether female marmots are reproductive or non-reproductive

The impacts of dust from unpaved roads on plant physiology and reproduction

The age at which females first reproduce, an important component of vertebrate life histories with effects on individual fitness and population dynamics

Concentration-discharge pattern where solute concentrations remain relatively constant across flow conditions, indicated by C-Q slope near zero

How changing weather patterns and climate conditions influence animal behavioral strategies

Areas of transition between adjacent, distinct ecosystems with unique species assemblages at the fringes of mature stands

Internal aboveground symbionts living within plant tissues that can produce alkaloids for plant defense

Nectar-secreting organs located on leaf laminae, petioles, rachis, bracts, stipules, pedicels, or fruit that attract arthropods
