Underwater Acoustic Ecology Metrics in an Alaska Marine Protected Area Reveal Marine Mammal Communication Masking and Management Alternatives

Frontiers in Marine Science, 2018
Vessel-generated underwater noise can affect humpback whales, harbor seals, and other marine mammals by decreasing the distance over which they can communicate and detect predators and prey.

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

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

Worldwide Assessment of National Glacier Monitoring and Future Perspectives

Mountain Research and Development, 2019
It is widely accepted that glaciers are retreating throughout the world and that their decline causes serious impacts on many societies. Knowledge of glacier distribution and quantification of glacier changes is crucial to assessing the impact of glacier

Impacts of tidewater glacier advance on iceberg habitat

Annals of Glaciology, 2023
Icebergs in proglacial fjords serve as pupping, resting and molting habitat for some of the largest seasonal aggregations of harbor seals (Phoca vitulina richardii) in Alaska.

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

Natural 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.

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

Frontiers 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

Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal [PDF]

, 2015
In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.
