The Effect of Height, Wing Length, and Wing Symmetry on Tabebuia rosea Seed Dispersal [PDF]

open access: yesJournal of Science International School Bangkok, 2014
The relationship between the vertical drop height and the horizontal distance traveled (dispersal ratio) was investigated for a sample of fifty Tabebuia rosea seeds by dropping the seeds from five heights ranging from 1.00 to 2.00 meters.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over

Interspecific variation in leaf phenology and its relationship with plant traits in a seasonal tropical forest

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 433-450, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf phenology plays an important role in plant life‐history strategies and in determining ecosystem‐level fluxes of carbon and water. In seasonal tropical forests, leaf phenology is highly variable among tree species, but limited quantitative data have hindered our ...

Host Status of Brazilian Native Tree Species to Root‐Knot Nematodes

open access: yesForest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Root‐knot nematodes (RKN, Meloidogyne spp.) are among the most important plant pathogenic organisms, causing significant damage, with a wide geographical distribution and being difficult to control. The ability of these nematodes to parasitize native trees from Brazilian biomes is little understood.
