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

A Circumpolar Perspective on the Contribution of Trees to the Boreal Forest Carbon Balance
TL;DR: In this paper , a tree-centered overview of the boreal forest carbon balance and a circumpolar perspective on the contribution of trees to boreal carbon dynamics is presented, together with an outlook addressing the trajectories of the circumboreal C dynamics in response to projected environmental changes.
Book ChapterDOI
The Past Shows the Future
TL;DR: In this article, the effects of the nearest past ice age on plants in the Arctic were studied and compared to the current distribution of plants and how they expanded their habitats after the last ice age, and the plant that came to the Arctic as the Ice Age retreated and the ice disappeared.
Book ChapterDOI
Arctic Connections to Global Warming and Health
TL;DR: In this paper, the importance of the Arctic is examined within a global context by summarizing the rapid environmental and societal changes that are occurring, identifying how changes in the Arctic provide strong feedbacks to the global climate system, and how environmental and health policy is mitigating, or failing to mitigate, the effects of a changing Arctic.
Biotic interactions in driving biodiversity : Insights into spatial modelling
TL;DR: The results show that plant–plant interactions consistently and significantly affect species performance and richness patterns, and that the guild, geographic range and traits of species can indicate the outcome and magnitude of the impact.
Journal ArticleDOI
Shrubs Compensate for Tree Leaf Area Variation and Influence Vegetation Indices in Post‐Fire Siberian Larch Forests
TL;DR: In this article , the authors investigated the relationship between tree density, tree LAI, and tall shrub LAI and satellite observations of Normalized Difference and Enhanced Vegetation Indices (NDVI and EVI).

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.
