Human-induced nitrogen input that has doubled biologically-available nitrogen on Earth

Environmental condition characterized by limited water availability

Variation in microclimatic conditions across small spatial scales, including differences in slope, aspect, and elevation that create diverse microclimatic niches

Variation in interspecific interactions across time periods over which organisms co-occur that leads to flexible network structure

Temporal variation in environmental conditions measured as standard deviation of temperature and vegetation indices

Variations in aerosol concentrations and properties across both spatial scales and temporal scales

How tree growth and biomass allocation patterns change based on local neighborhood tree density and competition

The positive relationship between species richness and the surveyed area, described by the power-law S=cA^z where c is the intercept and z measures the rate of community turnover

Excessive extracellular stalk production by individual cells that coalesce to form a continuous mat covering the stream bottom

Shallow subsurface zone where river and groundwater mix, serving as a source or sink of reactive nitrogen depending on water residence times and nitrogen transformation rates

Variation in organismal body size both within and between species, influenced by environmental and genetic factors

Behavioral displays performed by animals during mating season to attract mates or compete for breeding opportunities

Widespread reductions in pollinator abundance and diversity observed globally, attributed to multiple environmental stressors

The selective choices made by organisms regarding where to construct nests, influenced by environmental factors that affect offspring survival and reproductive success.

Organic carbon derived from sedimentary rocks that is often poorly quantified and influences soil organic carbon composition, age, and stability

Human activities that impose novel challenges on a wide range of species, which can negatively influence individuals, populations, and communities as well as ecosystems

Differential expression of genotypes across environmental conditions, indicating genetic variation in phenotypic plasticity

Loss of species diversity through various processes including lack of adaptation to changing conditions, phenological changes, shifts in species abundance and ranges, and habitat loss

Alpine plants growing in clumps with multiple species interacting in close proximity, affecting microhabitats and species interactions

Spatial variability in biogeochemical processes and solute sources within watersheds, particularly between shallow soil zones and deeper groundwater zones

Ability of forest ecosystems to maintain function during water-limited conditions through adaptive water use strategies

Social systems where individuals have flexibility in their social behaviors and group membership rather than being obligately social

Variation in soil moisture conditions creating distinct dry and wet meadow habitat types

tendency of an organism to stay in or habitually return to a particular area

Differences between males and females in morphology, physiology, and/or behaviour resulting from differences in strength and shape of selection acting on each sex

The geographic or environmental boundaries beyond which species cannot persist, potentially influenced by biotic interactions

Temporal alignment between consumer energy requirements and food source availability across trophic levels

A mode of sex expression where male sterile (female) plants and hermaphroditic plants coexist within a population

The degree to which individuals can be discriminated from one another based on their vocalizations, quantified using information theory

Directed aggression toward conspecifics, increasing spatial distancing from or decreasing huddling with unfamiliar conspecifics

The lowest part of the atmosphere directly influenced by the Earth's surface

Streambed and boggy areas around streams as well as uphill water flows that are critical regions for DOC concentrations

The relationship between solute concentrations and discharge in streams, widely used as a metric for interpreting interaction of hydrological processes, chemical transport, and mineral reactions in wa...

Daily activity patterns and rhythms in organism behavior

Chemical cues released by predators that benefit prey by providing information about predator presence

Bacterial communities that colonize and live within floral nectar, potentially affecting nectar chemistry and pollinator behavior

Mating system where males compete with one another over access to matelines consisting of groups of related females

The distribution of individuals across different size or age classes within a population
