TL;DR: Reviews of the literature concerning deserts, boreal forests, tropical forests, lakes, and wetlands lead to the conclusion that extant data are insufficient to conclusively resolve the relationship between diversity and productivity, or that patterns are variable with mechanisms equally varied and complex.

TL;DR: The data show that temperature-induced drought stress has disproportionately affected the most rapidly growing white spruce, suggesting that, under recent climate warming, drought may have been an important factor limiting carbon uptake in a large portion of the North American boreal forest.

TL;DR: In this paper, the authors systematically sampled 1558 white spruce at 13 treeline sites in the Brooks Range and Alaska Range and found that high mean temperatures in July decreased the growth of 40% of treeline areas in Alaska, whereas warm springs enhance growth of additional 36% of trees and 24% show no significant correlation with climate.

TL;DR: In this article, the authors evaluated changes in forest productivity since 1982 across boreal Alaska by linking satellite estimates of primary productivity and a large tree-ring data set, and found consistent growth increases at the boreal tundra ecotones that contrast with drought-induced productivity declines throughout interior Alaska.

TL;DR: Evidence suggesting that changes in boreal climate of the magnitude projected for the 21st century may be gradual at the northern forest limit or where seed dispersal limits species distribution is reviewed, suggesting forest composition may be quite resilient to climate change in the central portions of a species range until some threshold is surpassed.
