Nitrogen and Phosphorus Allocation Strategies in a Chronosequence of Tropical Dry Forests: Plant Coordination and Environmental Drivers

open access: yesBiotropica, Volume 57, Issue 2, March 2025.
We explored the allocation strategies of N and P in leaves and fine roots (metabolic organs) and, in stems and coarse roots (woody organs) of nine dominant tree species in secondary tropical dry forests using scaling analysis. The scaling relationships of P versus N concentrations in non‐leaf organs were isometric across secondary succession and ...

Aridity and forest age mediate landscape scale patterns of tropical forest resistance to cyclonic storms

open access: yesJournal of Ecology, Volume 113, Issue 1, Page 53-67, January 2025.
These findings show that selection towards drought‐tolerant traits across aridity gradients, such as short stature and dense wood, enhances resistance to hurricanes. However, forest age modulated responses to hurricanes, with older forests being less resistant across the islands.

Tree species abundance changes at the edges of their climatic distribution: An interplay between climate change, plant traits and forest management

open access: yesJournal of Ecology, Volume 112, Issue 12, Page 2785-2797, December 2024.
Our research emphasizes the crucial impact of historical forest management in shaping the current distribution of tree species. After controlling for the effect of forest management, climate change directly influenced tree demographics, favouring species based on their traits.

PicoCam: High‐resolution 3D imaging of live animals and preserved specimens

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 11, Page 1980-1989, November 2024.
Abstract The PicoCam system is a multi‐camera photogrammetry rig used for generating high‐resolution 3D models of animals in the field, or preserved specimens in laboratory or museum settings. The digital measurement of 3D models is increasingly useful for studying body shape. However, methods that capture sub‐millimetric detail often do so at the cost

Land use history and landscape forest cover determine tropical forest recovery

open access: yesJournal of Applied Ecology, Volume 61, Issue 10, Page 2365-2381, October 2024.
Both a higher land use intensity and fragmented forest landscape decreases the speed of forest recovery, indicating that human actions and landscape transformation shape the course of succession. Restoration in fragmented forest landscapes through natural regeneration is more suitable in areas with low previous land use intensity, higher forest ...
