Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Assessing responses of reef island seabirds to environmental and anthropogenic drivers
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Ecological Entomology, Volume 51, Issue 5, Page 1025-1035, October 2026.Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Green Hydrogen in Brazilian Media: Dominant Narratives and Missing Dimensions of the Energy Trilemma
Politics &Policy, Volume 54, Issue 5, October 2026.ABSTRACT Media discourses help shape the visibility and legitimacy of energy transition pathways in the public sphere. This study examines how Brazilian mainstream newspapers framed green hydrogen and assesses the alignment of these narratives with the energy trilemma: energy security, environmental sustainability, and social accessibility. We analyzed
