Arctic Science, 2023 Remote sensing has detected recent trends of increased vegetation productivity on the Bathurst caribou herd’s range. The cause of this spectral greening is unknown but is hypothesized to be the result of a change in the composition, establishment ...

Holocene vegetation dynamics of circum-Arctic permafrost peatlands [PDF]
, 2023 Vegetation shifts in circum-Arctic permafrost peatlands drive feedbacks with important consequences for peatland carbon budgets and the extent of permafrost thaw under changing climate.

Assessing patterns and biogeochemical impacts of shrubification in sedge fens of the Hudson Bay subarctic tundra [PDF]
, 2021 Mean annual air temperatures in Arctic regions have increased by about 2–3°C over the past 50 years. As a result, the abundance and maximum height of woody shrub species has increased (shrubification) at sites around the circumpolar Arctic.

Shrub expansion in maritime forest responding to sea level rise
Frontiers in Forests and Global Change, 2023 Expansion of shrubs has been observed in a number of biomes and in response to diverse global change drivers. Noting shrub expansion in coastal forests affected by sea level rise, we began to monitor shrub populations in a transgressing loblolly pine ...

Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes [PDF]
Hydrology and Earth System Sciences, 2022 Snow represents the largest potential source of water for thermokarst lakes, but the runoff generated by snowmelt (freshet) can flow beneath lake ice and via the outlet without mixing with and replacing pre-snowmelt lake water.

Arctic Science, 2022 Climate warming allows generalist boreal consumers to expand into Arctic ecosystems. We present experimental and observational field data showing that a generalist boreal insect pest—the winter moth (Operophtera brumata Linnaeus, 1758)—is expanding its ...

, 2018 Widespread expansion of shrubs is occurring across the Arctic. Shrub expansion will substantially alter arctic wildlife habitats. Identifying which wildlife species are most affected by shrubification is central to predicting future arctic community ...
