Competitor Richness Outweighs Climate and Land Cover in Explaining Abundance Variation of a Neotropical Fruit Bat

open access: yesAustral Ecology, Volume 51, Issue 1, January 2026.
ABSTRACT Understanding which processes regulate spatial variation in species abundance across their ranges is key in ecology. Species abundances may be affected by several factors, such as climate, elevation, land cover, species interactions and habitat protection status. However, few studies have focused on these effects synergistically across species

Mapping the density of giant trees in the Amazon

open access: yesNew Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Scaling the effects of size and temperature on animal consumption rates from individuals to populations in a subtropical reef fish

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3385-3395, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Measuring how temperature and body size drive individual consumption rates is fundamental to predict how climate change might shape population‐level consumption pressure. Yet, such measurements remain rare.

Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.
Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

Growth–survival trade‐off in temperate trees is weak and restricted to late‐successional stages

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3466-3477, November 2025.
Our findings highlight a role of disturbances in filtering life‐history strategies and their potential impact on forest dynamics and global carbon cycling, but also a need to better understand the mediating processes of tree demographic trade‐offs.
