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

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

Elaboración y caracterización de pisos de ingeniería elaborados con maderas de diferentes densidades

Madera y Bosques, 2023
Una opción para incrementar el valor de las maderas de baja densidad puede ser el combinarlas con especies de densidades más altas. A los productos que combinan madera de diferentes propiedades se les conoce como productos de ingeniería. El presente trabajo tuvo como objetivo diseñar, producir y evaluar, a través de sus propiedades físicomecánicas, un ...

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 ...

Variation of non‐structural carbohydrates across the fast–slow continuum in Amazon Forest canopy trees

Functional Ecology, Volume 36, Issue 2, Page 341-355, February 2022., 2022
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Tropical tree species span a range of life‐history strategies within a fast–slow continuum. The position of a species within this continuum is thought to reflect a negative relationship between growth and storage, with fast‐growing species allocating ...

Functional diversity and redundancy of tropical forests shift with elevation and forest‐use intensity

Journal of Applied Ecology, Volume 58, Issue 9, Page 1827-1837, September 2021., 2021
High functional diversity and functional redundancy from lowland to mid‐elevation tropical forests suggest that these ecosystems can be resilient to future disturbances. Our results indicate that the ability of high‐elevation forests may be particularly susceptible to climate change and increasing forest‐use intensity. For these high‐elevation forests,
