Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

open access: yesJournal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Organisms as Ecosystems/Ecosystems as Organisms [PDF]

open access: yesBiological Theory, 2014
It is well known that most organisms are composed of smaller subunits, including not only cells and semi-independent organelles but often also a whole suite of parasites, commensal organisms, and other symbionts (Buss 1987; Margulis 1970; Bouchard and Huneman 2013).

Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.

More than proteins for empty stomachs: Wild meat in the BaTonga food system

open access: yesPeople and Nature, Volume 8, Issue 10, Page 3298-3310, October 2026.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

Intraspecific variability rivals interspecific differences in root traits of temperate tree seedlings

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3114-3132, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global change and associated disturbances are increasing the risk of regeneration failure for tree species in temperate forests. Seedlings are particularly vulnerable to water stress due to their shallow root systems, making below‐ground plasticity a potentially key ...
