Scrutinise the variations of glaciers and their climatic attributions in the Sanjiangyuan National Park during 1969–2018

Advances in Climate Change Research, 2022
Since 2020, the first national park of China, the Sanjiangyuan National Park (Park) has been put into operation in China. This Park is one of the most vulnerable regions to the rapid climate change in the Tibetan Plateau.

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

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.

Fine-scale variability in iceberg velocity fields and implications for an ice-associated pinniped [PDF]

The Cryosphere
Icebergs found in proglacial fjords serve as important habitats for pinnipeds in polar and subpolar regions. Environmental forcings can drive dramatic changes in the overall reduction in ice coverage across fjords in the circumpolar regions, with ...

Biologically Important Areas II for cetaceans within U.S. and adjacent waters – Gulf of Alaska Region

Frontiers in Marine Science, 2023
We delineated and scored Biologically Important Areas (BIAs) for cetacean species in the Gulf of Alaska region. BIAs represent areas and times in which cetaceans are known to concentrate for activities related to reproduction, feeding, and migration, and
