Thermal Vulnerability of Reef Fish and Implications for Subsistence Fisheries Throughout the Caribbean

open access: yesGlobal Change Biology, Volume 32, Issue 10, October 2026.
We present species distribution models of seven finfish species that are important for coastal subsistence. Models highlight potential for substantial future shifts in distributions in the coming decades. Information on changing climate suitability can support regional planning including marine protected area expansion to help bolster food security and

Impacts of Species Introductions on the Trait Diversity of Interacting Avian Frugivores and Fleshy‐Fruited Plants Depend on Native Trait Diversity

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 10, October 2026.
ABSTRACT Aim The introduction of non‐native species to native ecological communities by humans is a major driver of global biodiversity change. Studying how species introductions influence interacting species is essential to understanding possible functional consequences of global change because biotic interactions are ecologically crucial.

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.
