Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

open access: yesEcological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Seasonal changes of water quality in a tropical shallow and eutrophic reservoir in the metropolitan region of Recife (Pernambuco-Brazil)

open access: yesAnais da Academia Brasileira de Ciências, 2014
This study investigated the water quality in an urban eutrophic reservoir in Northeastern Brazil, considering the influence of seasonality. Monthly, samples were collected in the sub-surface reservoir.

Fish loss in tropical coastal ecosystems can jeopardise nutrient supply to traditional fishing communities: A case study from Northeast Brazil

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1248-1260, May 2026.
Abstract Fisheries constitute one of the major benefits that oceans provide for people. Yet anthropogenic pressures and global changes are disrupting coastal systems, eroding marine biodiversity and threatening the food security of traditional populations.

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.
