Changes in Imja Tsho in the Mount Everest region of Nepal [PDF]

The Cryosphere, 2014
Imja Tsho, located in the Sagarmatha (Everest) National Park of Nepal, is one of the most studied and rapidly growing lakes in the Himalayan range. Compared with previous studies, the results of our sonar bathymetric survey conducted in September of 2012

Evaluating density-weighted connectivity of black bears (Ursus americanus) in Glacier National Park with spatial capture–recapture models [PDF]

Movement Ecology
Background Improved understanding of wildlife population connectivity among protected area networks can support effective planning for the persistence of wildlife populations in the face of land use and climate change.

Wolverines use spatial memory to plan efficient routes through rugged terrain [PDF]

Movement Ecology
Background To navigate, animals balance nearby perceptual cues, random search, and memory. Isolating the role of memory, however, remains difficult. Methods Here, we use a mechanistic movement model to do so, simulating animals responding solely to local

Acoustic Emissions from Grey Glacier, Chilean Patagonia: dataset of infrasound measurements [PDF]

Scientific Data
Calving is a critical process contributing to ice mass loss in tidewater and lake-terminating glaciers, with significant implications for freshwater input, glacier dynamics, and climate change. Infrasound emissions generated by calving events represent a

Bighorn sheep associations: understanding tradeoffs of sociality and implications for disease transmission [PDF]

PeerJ, 2023
Sociality directly influences mating success, survival rates, and disease, but ultimately likely evolved for its fitness benefits in a challenging environment.

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.

Maritime glacier retreat and terminus area change in Kenai Fjords National Park, Alaska, between 1984 and 2021

Journal of Glaciology, 2023
Glacier change in Kenai Fjords National Park in southcentral Alaska affects local terrestrial, fresh water and marine ecosystems and will likely impact ecotourism.

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.

Partial COVID-19 closure of a national park reveals negative influence of low-impact recreation on wildlife spatiotemporal ecology

Scientific Reports, 2023
Human presence exerts complex effects on the ecology of species, which has implications for biodiversity persistence in protected areas experiencing increasing human recreation levels.

Documenting 20th and 21st century glacier change and landscape evolution with maps and land, aerial, and space-based geospatial imagery in Alaska’s Kenai Mountains

Nova Geodesia, 2022
Data fusion and analysis of maps and remote sensing data collected from different spatial perspectives (ground, air, and space) at different times from the early 20th century to the present using different sensors were used to answer questions about ...
