Spatiotemporal dynamics and driving mechanisms of grassland desertification in the Qilian Mountain National Park, northeast of the Tibetan Plateau

open access: yesEcological Indicators
Grasslands are important terrestrial ecosystems that have suffered severe desertification. However, the driving factors and mechanisms of grassland desertification remain unclear.

Ecosystem-Based Fishery Management in the Bering Sea

open access: yesJournal of Marine Science and Engineering, 2023
The waters of the Bering Sea are among the most productive on earth, having supported major commercial fisheries for up to ~60 years and First Nations cultures for millennia [...]

Changing drivers of regional large magnitude avalanche frequency throughout Colorado, USA [PDF]

open access: yesNatural Hazards and Earth System Sciences
Large magnitude snow avalanches (destructive size ≥ D3) impact settlements, transportation corridors, and public safety worldwide. In Colorado, United States, avalanches have killed more people than any other natural hazard since 1950.

Interannual Glacier Variability and Accelerated Albedo Decline in Northeastern Tibetan Plateau: Multidecadal Remote Sensing Insights (1986–2024)

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Mountain glaciers are key indicators of climate change, with their retreat and surface albedo variations exerting significant impacts on regional water resources and surface energy balance.

Species conflict at Earth’s edges – Contests, climate, and coveted resources

open access: yesFrontiers in Ecology and Evolution, 2022
Direct conflict between species is an infrequently witnessed biological phenomenon. Potential drivers of such contests can include climate change, especially at Earth’s high elevation and latitudinal extremes where temperatures warm 2–5 times faster than

Imprints of sea ice, wind patterns, and atmospheric systems on summer water isotope signatures at Hercules Névé, East Antarctica [PDF]

open access: yesThe Cryosphere
This study investigated the influence of summer climate variability on water isotopes (δ18O, δ2H, and deuterium excess[dexc]) in a Hercules Névé ice core from Antarctica.

Local topography increasingly influences the mass balance of a retreating cirque glacier [PDF]

open access: yesThe Cryosphere, 2018
Local topographically driven processes – such as wind drifting, avalanching, and shading – are known to alter the relationship between the mass balance of small cirque glaciers and regional climate.

Mountain goat declines in a protected, interior, native population

open access: yesEcosphere
A shifting climate poses threats to alpine‐adapted species including mountain goats. We used long‐term (12 years) citizen science monitoring data and Bayesian N‐mixture modeling to estimate population trends and drivers of population metrics among ...

A New Method for Automatic Glacier Extraction by Building Decision Trees Based on Pixel Statistics

open access: yesRemote Sensing
Automatic glacier extraction from remote sensing images is the most important approach for large scale glacier monitoring. Commonly used band calculation indices to enhance glacier information are not effective in identifying shadowed glaciers and debris-
