Assessing and quantifying variations in the functioning of marine food webs across scales

Conservation Biology, EarlyView.
Abstract The mismatch between the scale of ecological processes and management decisions represents a significant challenge in marine conservation. This misalignment can result in ineffective conservation measures and compromise the sustainability of marine ecosystems.

Coinvasional disruptions to island pollinator networks

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Response of endemic lizard populations to attempted eradication of invasive predators on a Galápagos island

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Integrating reptile monitoring into invasive predator eradication programmes can reveal rapid responses in ecologically important, yet frequently overlooked, components of island ecosystems. Accounting for habitat variation alongside changes in predator communities will improve interpretation of post‐eradication population responses and inform ...

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

Anais 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.

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

Conservation 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

Ecological 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 ...

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

People 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.
