UAV data and deep learning: efficient tools to map ant mounds and their ecological impact

Remote Sensing in Ecology and Conservation
High‐resolution unoccupied aerial vehicle (UAVs) data have alleviated the mismatch between the scale of ecological processes and the scale of remotely sensed data, while machine learning and deep learning methods allow new avenues for quantification in ...

Expert solicitation informs conservation planning for a subarctic mammal susceptible to climate change: the collared pika (Ochotona collaris)

Global Ecology and Conservation
Conservation plans for species at risk are critical for identifying threats and determining means to manage them to permit species persistence. However, the threats faced by many species are rarely fully understood.

Socio-economic effects of changing vegetation in Arctic Alaska [PDF]

, 2018
Vegetation change is complex and as a result the socioeconomic impacts vary. Shrubification has consequences for energy production, transportation but more information is needed. Erosion is a major issue for many communities and how vegetation influences

The changing face of the Arctic: four decades of greening and implications for tundra ecosystems

Frontiers in Environmental Science
Arctic landscapes occupy a nexus of environmental change processes, globally significant soil carbon stores, wildlife populations, and subsistence-based human societies.

Alaska’s boreal-tundra resolved with vegetation height from commercial imagery and a foundation model

Environmental Research Letters
A reconfiguration of vegetation structure patterns in the boreal forest-tundra ecotone and Low Arctic tundra is underway, driven by shrubification, tree expansion, permafrost thaw, and disturbance regimes linked to rapid warming.

Improving high latitude vegetation representation in the ORCHIDEE land surface model by introducing shrub PFTs

International audienceHigh-latitude terrestrial ecosystems are significantly affected by anthropogenic climate change. One of the most notable observed ecological responses is an expansion of shrubs across tundra ecosystems.

Changing Arctic Vegetation: Examining Shrubification, Permafrost Vulnerability, and Land-Atmosphere Interactions

Climate change is causing the Arctic to warm faster than anywhere else on Earth. The Arctic is an important piece of the global carbon cycle, storing half of the Earth's soil carbon in perennially frozen permafrost.
