Concepts

Physiological stress experienced by plants due to reduced water availability that can harm fitness by inducing leaf loss, reducing flower size, and decreasing seed production

Changes in species geographic distributions in response to changing climate conditions, typically involving movement to higher elevations or latitudes

Limitations on activity imposed by temperature and radiation conditions

The ability of organisms to adjust to changing climatic conditions through genetic, phenotypic, or behavioral changes

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

Temperature accumulation metric calculated using averaging method with base temperature, used to predict insect phenology and plant development

The effects of long-term warming on hydrological processes, including changes in snowpack dynamics, growing season length, and water demand by vegetation

Computational approach to calculate radiation fluxes through the atmosphere under specified atmospheric conditions

The fraction of solar radiation reflected by the surface, with snow-covered surfaces having high albedo (0.8) and snow-free surfaces having lower values

Direct damage to plant buds and flowers from freezing temperatures occurring during vulnerable developmental stages

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

Standardized measure of water deficit calculated using the Standardized Precipitation Evapotranspiration Index (SPEI) over 12-month periods

Ecosystem responses to climate change that exert positive or negative feedbacks on climate, mediated by slow-moving factors such as shifts in vegetation community composition

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

The role of atmospheric aerosols in cloud formation and precipitation by acting as cloud condensation nuclei (CCN) and ice-nucleating particles (INPs)

Future climate scenarios based on different greenhouse gas emission pathways, specifically RCP 4.5 and RCP 8.5 scenarios

The difference between net radiation flux at the surface under all-sky and clear-sky conditions, accounting for both downwelling and upwelling radiation changes

Physical processes affecting snow particle formation, growth, and characteristics including aggregation, riming, sublimation, and fragmentation

The balance of vertical radiative, conductive, and turbulent energy transfer across the infinitely thin plane of the surface

Heat transfer through soil via molecular conduction

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

Enhanced plant growth due to increased atmospheric carbon dioxide concentrations

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

Higher temperatures shorten larval developmental period leading to smaller adults, where body size exhibits temperature-mediated variation
