Tropical dry woodland loss occurs disproportionately in areas of highest conservation value

open access: yesGlobal Change Biology, Volume 29, Issue 17, Page 4880-4897, September 2023., 2023
Tropical and subtropical dry woodlands are crucial for biodiversity and carbon storage, yet they face high deforestation pressures. We investigated the interplay of deforestation frontiers, protected areas, Indigenous Peoples' lands and conservation priorities in these woodlands.

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 1, Page 49-69, January 2023., 2023
Abstract Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser ...

Aridity and geochemical drivers of soil micronutrient and contaminant availability in European drylands

open access: yesEuropean Journal of Soil Science, Volume 73, Issue 1, January–February 2022., 2022
Abstract Dryland soils provide different societal and environmental services, such as food supply and biodiversity support. In Europe, most of the dryland areas are devoted to agriculture. In the next decades, both European and worldwide drylands are expected to suffer with increased intensity due to the expected climate change‐derived rise in aridity.

sPlotOpen – An environmentally balanced, open‐access, global dataset of vegetation plots

open access: yesGlobal Ecology and Biogeography, Volume 30, Issue 9, Page 1740-1764, September 2021., 2021
Abstract Motivation Assessing biodiversity status and trends in plant communities is critical for understanding, quantifying and predicting the effects of global change on ecosystems. Vegetation plots record the occurrence or abundance of all plant species co‐occurring within delimited local areas.

Mechanisms driving plant functional trait variation in a tropical forest

open access: yesEcology and Evolution, Volume 11, Issue 9, Page 3856-3870, May 2021., 2021
We applied a statistical technique to analyze the relative amount of variation within plant functional traits associated with (a) environmental heterogeneity and spatial distance, as well as (b) bioclimatic variables in response to canopy‐light regime and soil nutrient availability. We found that plant functional reaction norms to bioclimatic variables
