How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Use and misuse of trait imputation in ecology: the problem of using out‐of‐context imputed values

open access: yesEcography, Volume 2025, Issue 6, June 2025.
Despite the progress in the measurement and accessibility of plant trait information, acquiring sufficiently complete data from enough species to answer broad‐scale questions in plant functional ecology and biogeography remains challenging. A common way to overcome this challenge is by imputation, or ‘gap‐filling' of trait values.

Towards a global understanding of tree mortality [PDF]

open access: yesnew phytologist.
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

Assisted migration of forest populations for adapting trees to climate change

open access: yesRevista Chapingo: Serie Ciencias Forestales y del Ambiente, 2016
En este trabajo se presenta evidencia de que el cambio climático es un proceso que está en curso y que las poblaciones de árboles forestales son genéticamente diferenciadas en caracteres cuantitativos debido a la adaptación en hábitats específicos.

Long‐term interventions by conservation and development projects support successful recovery of tropical peatlands in Amazonia

open access: yesPeople and Nature, Volume 7, Issue 4, Page 871-886, April 2025.
Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.
