Panama Canal expansion and shifts in fishing practices: A social‐ecological network approach

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1520-1532, May 2026.
Abstract Species introductions have spiked over the past two centuries due to globalization. These introductions impact ecosystems, but may also have long‐term implications for human communities. In one of the world's hubs for global shipping, the Panama Canal, a recent canal expansion has coincided with an increase in marine fishes entering the ...

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Morphological, Molecular, and Isotopic Approaches to Termite Ecology: A Mangrove Case Study

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Termite communities in Caribbean mangroves, though species‐poor, sustain crucial decomposition and nutrient cycling. Their overlapping niches and stochastic assembly highlight termites' resilience and ecological importance in supporting the functioning of these challenging coastal ecosystems.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Dietary resilience of coral reef fishes to habitat degradation

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Record phenological responses to climate change in three sympatric penguin species

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 455-469, March 2026.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.
