Many studies have reported that the Arctic is greening; however, we lack an understanding
of the detailed patterns and processes that are leading to this observed greening. The …

Vegetation indices are corner stones in vegetation monitoring. However, previous field
studies on lichens and NDVI have been based on passive sensors. Active handheld …

High-latitude treeless ecosystems represent spatially highly heterogeneous landscapes with
small net carbon fluxes and a short growing season. Reliable observations and process …

A warming Arctic has been associated with increases in aboveground plant biomass,
specifically shrubs, and changes in vegetation cover. However, the magnitude and direction …

Plant functional traits are key drivers of ecosystem processes. However, plot-based
monitoring of functional composition across both large spatial and temporal extents is a time …

Global warming has pronounced effects on tundra vegetation, and rising mean temperatures
increase plant growth potential across the Arctic biome. Herbivores may counteract the …

High-latitude systems in northwestern Canada and Alaska have warmed rapidly. The aim of
this study was to examine how a remotely sensed proxy of vegetation productivity varied …

The timing and duration of the plant growing season and its period of peak activity have
shifted globally in response to climate change. These changes alter the period of maximum …

The phenology of Arctic plants is an important determinant of the pattern of carbon uptake
and may be highly sensitive to continued rapid climate change. Eriophorum vaginatum …

Increases in shrub growth and canopy cover are well documented community responses to
climate warming in the Arctic. An important consequence of larger deciduous shrubs is …
