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

Homogenization in Species Composition and No Change in Aboveground Biomass Across Tibetan Permafrost Regions Over Ten Years
TL;DR: This paper conducted a broad-scale resampling project in the permafrost region of Tibet to examine if plant production and diversity had changed over time, finding that aboveground biomass increased for legumes and forbs, but decreased for grasses and sedges.

Carbon budget in permafrost and non-permafrost regions and its controlling factors in the grassland ecosystems of Mongolia
TL;DR: In this paper , the effects of freeze-thaw cycles on the grassland ecosystem carbon budget between a permafrost area (PA) and a non-permafrost region (NPA) were compared.

TL;DR: In this paper , an unoccupied aerial vehicle (UAV) with a ground sampling distance (GSD) of 3 cm was applied to a permanent research plot (1 ha), while spaceborne PlanetScope multi-temporal data with GSD of 3 m were used for a wider area of 250 ha.

Dwarf-shrubs dynamics in Mediterranean high mountain ecosystems
TL;DR: In this paper, the authors used a comprehensive set of environmental factors across a broad temporal span to model, at a fine-scale, both the current spatial distribution and the change in shrub cover over the past 60 years.

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.

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.
