Changes in species geographic distributions in response to changing climate conditions, typically involving movement to higher elevations or latitudes
elevation gradient
intraspecific variation
Raw material on which ecological and evolutionary processes act - variation of traits within species that can mediate responses to biotic and abiotic factors
pond hydroperiod
The frequency and duration of annual pond inundation vs. exposure, with categories including temporary ponds (dry annually in early summer), semi-permanent ponds (dry in late summer in most but not al...
nitrogen pollution
Human-induced nitrogen input that has doubled biologically-available nitrogen on Earth
aridity
Environmental condition characterized by limited water availability
microclimate heterogeneity
Variation in microclimatic conditions across small spatial scales, including differences in slope, aspect, and elevation that create diverse microclimatic niches
temporal flexibility
Variation in interspecific interactions across time periods over which organisms co-occur that leads to flexible network structure
environmental variability
Temporal variation in environmental conditions measured as standard deviation of temperature and vegetation indices
spatiotemporal variability
Variations in aerosol concentrations and properties across both spatial scales and temporal scales
stand density effects
How tree growth and biomass allocation patterns change based on local neighborhood tree density and competition
Species-area relationship
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
seasonal cycle
algae bloom
Excessive extracellular stalk production by individual cells that coalesce to form a continuous mat covering the stream bottom
hyporheic zone
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
body size variation
Variation in organismal body size both within and between species, influenced by environmental and genetic factors
courtship displays
Behavioral displays performed by animals during mating season to attract mates or compete for breeding opportunities
pollinator decline
Widespread reductions in pollinator abundance and diversity observed globally, attributed to multiple environmental stressors
nesting preferences
The selective choices made by organisms regarding where to construct nests, influenced by environmental factors that affect offspring survival and reproductive success.
petrogenic organic carbon
Organic carbon derived from sedimentary rocks that is often poorly quantified and influences soil organic carbon composition, age, and stability
anthropogenic disturbance
Human activities that impose novel challenges on a wide range of species, which can negatively influence individuals, populations, and communities as well as ecosystems
genotype by environment interaction
Differential expression of genotypes across environmental conditions, indicating genetic variation in phenotypic plasticity
hybrid zone
A geographic region where genetically distinct populations meet and produce offspring of mixed ancestry
biodiversity loss
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
meteorology
spatial clustering
Alpine plants growing in clumps with multiple species interacting in close proximity, affecting microhabitats and species interactions
biogeochemical heterogeneity
Spatial variability in biogeochemical processes and solute sources within watersheds, particularly between shallow soil zones and deeper groundwater zones
drought resilience
Ability of forest ecosystems to maintain function during water-limited conditions through adaptive water use strategies
facultative sociality
Social systems where individuals have flexibility in their social behaviors and group membership rather than being obligately social
meadow moisture gradient
Variation in soil moisture conditions creating distinct dry and wet meadow habitat types
philopatry
tendency of an organism to stay in or habitually return to a particular area
sexual dimorphism
Differences between males and females in morphology, physiology, and/or behaviour resulting from differences in strength and shape of selection acting on each sex
species range limits
The geographic or environmental boundaries beyond which species cannot persist, potentially influenced by biotic interactions
trophic synchrony
Temporal alignment between consumer energy requirements and food source availability across trophic levels
gynodioecy
A mode of sex expression where male sterile (female) plants and hermaphroditic plants coexist within a population
latitudinal gradient
spatial patterns
vocal individuality
The degree to which individuals can be discriminated from one another based on their vocalizations, quantified using information theory
antisocial behavior
Directed aggression toward conspecifics, increasing spatial distancing from or decreasing huddling with unfamiliar conspecifics
atmospheric boundary layer
The lowest part of the atmosphere directly influenced by the Earth's surface
riparian zone
Streambed and boggy areas around streams as well as uphill water flows that are critical regions for DOC concentrations
adaptation
concentration-discharge relationship
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...
diel patterns
Daily activity patterns and rhythms in organism behavior
kairomones
Chemical cues released by predators that benefit prey by providing information about predator presence
nectar-inhabiting bacteria
Bacterial communities that colonize and live within floral nectar, potentially affecting nectar chemistry and pollinator behavior
polygamous mating system
Mating system where males compete with one another over access to matelines consisting of groups of related females
