TLDR
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).Abstract:
Temperature is increasing at unprecedented rates across most of the tundra biome(1). Remote-sensing data indicate that contemporary climate warming has already resulted in increased productivity ov ...read more

Root trait variation along a sub‐arctic tundra elevational gradient
TL;DR: In this article , the effects of elevation-associated temperature change on twelve chemical and morphological fine root traits of plant species and plant communities in a Swedish subarctic tundra were investigated.
Journal ArticleDOI
Reducing model uncertainty of climate change impacts on high latitude carbon assimilation.
TL;DR: In this paper, the authors review the current understanding and model representation of GPP in northern latitudes, focusing on vegetation composition, phenology, and physiology, and consider how climate change alters these three components.
Dissertation
A green future with thawing permafrost mires? : a study of climate-vegetatiojn interactions in European subarctic peatlands
TL;DR: In this paper, the impact of increased snow cover on plant photosynthesis was assessed through field experiments on a subarctic permafrost mire, where the snow cover was manipulated during seven winters using snow fences.
Journal ArticleDOI
Dispersal and fire limit Arctic shrub expansion
TL;DR: The authors used high-resolution satellite imagery across Alaska and western Canada to show that observed shrub expansion has not been controlled by environmental suitability during 1984-2014, but can only be explained by considering seed dispersal and fire.

TL;DR: In this paper, the authors performed a re-visitation study, using a set of 30 georeferenced historical plots newly collected after 20 years on two EU habitats (Galium magellense community growing on screes (8120 EU) and Trifolium thalii community of snowbeds (6170 EU)) in the Maiella National Park (MNP), which is one of the most threatened Mediterranean mountains in Europe.

Controlling the false discovery rate: a practical and powerful approach to multiple testing
Yoav Benjamini,Yosef Hochberg +1 more
TL;DR: In this paper, a different approach to problems of multiple significance testing is presented, which calls for controlling the expected proportion of falsely rejected hypotheses -the false discovery rate, which is equivalent to the FWER when all hypotheses are true but is smaller otherwise.

ggplot2: Elegant Graphics for Data Analysis
TL;DR: This book describes ggplot2, a new data visualization package for R that uses the insights from Leland Wilkisons Grammar of Graphics to create a powerful and flexible system for creating data graphics.

Rapid Range Shifts of Species Associated with High Levels of Climate Warming
TL;DR: A meta-analysis shows that species are shifting their distributions in response to climate change at an accelerating rate, and that the range shift of each species depends on multiple internal species traits and external drivers of change.

TL;DR: In this article, the NDVI 8-km equal area dataset from July 1981 through December 2004 for all continents except Antarctica was used to produce a Normalized Difference Vegetation Index (NDVI) 8.
