TL;DR: In this paper, remote sensing data indicate that contemporary climate warming has already resulted in increased productivity and increased productivity in the tundra biome (Tundra Tundra Bi biome).
Journal ArticleDOI
Tundra vegetation change near Barrow, Alaska (1972–2010)
TL;DR: The most dramatic changes in the cover of bryophytes, graminoids and bare ground coincided with a lemming high in 2008 as mentioned in this paper, while the response of other plant functional groups varied.
Journal ArticleDOI
Exclusion of brown lemmings reduces vascular plant cover and biomass in Arctic coastal tundra: resampling of a 50+ year herbivore exclosure experiment near Barrow, Alaska
TL;DR: The role of lemmings in plant communities and their contribution to the greening of the Arctic was investigated in this paper, where the authors measured plant cover and biomass in 50 + year old lemming exclosures and control plots in the coastal tundra near Barrow, Alaska.
Journal ArticleDOI
High spatial resolution decade-time scale land cover change at multiple locations in the Beringian Arctic (1948–2000s)
TL;DR: In this article, the authors created multi-temporal high spatial resolution land cover maps for seven locations in the Beringian Arctic and assessed the change in land cover over time.
Journal ArticleDOI
Estimated change in tundra ecosystem function near Barrow, Alaska between 1972 and 2010
TL;DR: The authors investigated the likely implications of plant community change on ecosystem function in tundra near Barrow, Alaska, using structural data from marked plots, established in 1972 and resampled in 1999, 2008 and 2010.
