More Rapid Reduction of Spring Snow Cover on the Western Tibetan Plateau by Emergent Constraint

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Snow cover is a critical component of climate, hydrological, and ecological systems, particularly in high‐altitude and high‐latitude regions. Global warming has driven substantial snow cover retreat, yet projections from climate models vary widely, hindering reliable climate change adaptation and policy planning.

Stage‐Specific Responses to Warming in Trojan Fir Across Early Life Stages: Germination, Seedling Survival, and Seedling Growth

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We investigated the effects of temperature, cold stratification, and light on germination and early seedling growth in Abies nordmanniana subsp. equi‐trojani (Trojan fir), an endangered endemic tree from northwestern Anatolia (Türkiye). Our results show that while higher fixed and alternating temperatures enhance germination, they also lead to ...

Diet Switching and Interspecific Competition in Sympatric Steppe Ungulates Under Seasonal Resource Variability

Ecology and Evolution, Volume 16, Issue 2, February 2026.
ABSTRACT Understanding the mechanisms of competition and coexistence among sympatric species is crucial for deepening our understanding of interspecific interactions and informing the conservation of rare and endangered wildlife. In this study, we utilized DNA macro‐barcoding technology to analyze the seasonal dietary habits of Kiang (Equus kiang) and ...

Phenology and carbon dioxide source/sink strength of a subalpine grassland in response to an exceptionally short snow season

Environmental Research Letters, 2013
Changes in snow cover depth and duration predicted by climate change scenarios are expected to strongly affect high-altitude ecosystem processes. This study investigates the effect of an exceptionally short snow season on the phenology and carbon dioxide

Branch Orientation: A Potential Indicator of Stem Rehydration and Water Stress

Hydrological Processes, Volume 40, Issue 2, February 2026.
Perceptual model illustrating how conifer branch position varies with tree water status. Well‐hydrated trees maintain branches in upward or horizontal positions due to higher water content and turgor pressure. As water stress increases, branches progressively droop downward.

Rain, Bark, and Residual Variability in Stemflow From Three Dominant Tree Species of a Southern Great Lakes Forest

Hydrological Processes, Volume 40, Issue 2, February 2026.
Terrestrial LiDAR and hydrology calibration were used to derive each tree's stemflow drainage area, normalising rainfall‐stemflow relations by contributing surface. The results show that Fagus grandifolia (beech) maintains a stronger, steeper hydrological response to rainfall (exhibited by a higher normalised yield) than Acer saccharum (maple) and ...

Changing Snow Regime Classifications Across the Contiguous United States

Water Resources Research
Climate change is impacting snow phenology in the Contiguous US (CONUS) and altering locations of elevated risk for floods driven by snowmelt. Our study uses a new spatial snow regime classification system to track climate driven changes in snow ...

ERTS-1 evaluation of natural resources management applications in the Great Basin [PDF]

The relatively cloud free weather in the Great Basin has allowed the accumulation of several dates of excellent ERTS-1 imagery. Mountains, valleys, playas, stream courses, canyons, alluvial fans, and other landforms are readily delineated on ERTS-1 ...
