The role of nutritional impairment in carbon-water balance of silver fir drought-induced dieback. [PDF]

Glob Chang Biol, 2022
Declining silver fir trees show lower foliar concentrations of essential nutrients such as P, K, Cu and Ni than non‐declining trees. This nutritional impairment exacerbates and amplifies the negative effects of drought on tree functioning and growth, considering the relationship of tree nutritional status with water‐use efficiency and growth resilience

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

New Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife. [PDF]

Conserv Biol
Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to

Nutrient‐based species selection is a prevalent driver of community assembly and functional trait space in tropical forests

Journal of Ecology, Volume 111, Issue 6, Page 1218-1230, June 2023., 2023
Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.

Forest loss and treeless matrices cause the functional impoverishment of sapling communities in old‐growth forest patches across tropical regions

Journal of Applied Ecology, Volume 59, Issue 7, Page 1897-1910, July 2022., 2022
In agreement with the LMFTS hypothesis, our results confirm that landscape modifications in regions undergoing high and long‐lasting deforestation greatly impoverish the functional composition and diversity of sapling communities. The shift from communities composed mainly by conservative attributes towards communities with a higher prevalence of ...
