Nonstructural carbohydrates predict survival in saplings of temperate trees under carbon stress
Functional Ecology, Volume 36, Issue 11, Page 2806-2818, November 2022., 2022 Read the free Plain Language Summary for this article on the Journal blog. Abstract Nonstructural carbohydrates (NSCs) mediate plant survival when the plant's carbon (C) balance is negative, suggesting that NSCs could predict plant survival under C stress.

Broad‐scale wood degradation dynamics in the face of climate change: A meta‐analysis
GCB Bioenergy, Volume 14, Issue 8, Page 941-958, August 2022., 2022 Using a meta‐analysis, we reviewed the effects of tree attributes and local climate on the time‐since‐death of coarse woody debris ranging in decomposition states. Our results suggest that warming will accelerate wood decomposition and significantly decrease the residence time in decay stages, leading to a decreased temporal window during which dead ...

Global Change Biology, Volume 27, Issue 24, Page 6394-6408, December 2021., 2021 Araucaria araucana wood anatomical traits evidenced a deterioration of the hydraulic system in declining trees. This pattern is site‐specific and started many decades before canopy dieback. In Chile, declining trees showed higher WUEi in the last 200 years, indicating an earlier stomatal closure to avoid water loss, and a potential greater carbon ...

The world's southernmost tree and the climate and windscapes of the southernmost forests
Ecography, Volume 44, Issue 1, Page 14-24, January 2021., 2021 The world's southernmost tree has been documented along with the condition and growth pattern of the world's southernmost forest on Isla Hornos, Chile. The distribution of trees at broad scales is strongly influenced by the abiotic environment and determining the position and condition of tree limits around the world is an important way to monitor ...

Pollen morphology of Nothofagus (Nothofagaceae, Fagales) and its phylogenetic significance [PDF]
, 2016 Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the classic hypothesis that Antarctica,
