Scientists' warning on the need for greater inclusion of dragonflies in global conservation

open access: yesInsect Conservation and Diversity, Volume 18, Issue 4, Page 465-484, July 2025.
Stressors to dragonflies are multiple, and in many cases interactive. Specialist species are at risk, while generalists can benefit from some human activities. Dragonflies are sentinels for conservation, being promising surrogates for other taxa while also being appealing to citizen science initiatives.

Gaps and spatial trends in the accurate data available on mosquitoes (Diptera, Culicidae) in Brazil: Inventory completeness and priority areas Lacunas e tendências espaciais nos dados precisos disponíveis sobre mosquitos (Diptera, Culicidae) no Brasil: Cobertura dos inventários e áreas prioritárias

open access: yesInsect Conservation and Diversity, Volume 18, Issue 4, Page 526-544, July 2025.
We compiled primary occurrence data for Culicidae in Brazil and our findings showed limitations in the spatial and temporal coverage of digital Culicidae data compared with the literature occurrence data. The Atlantic and Amazon Forests presented well‐surveyed inventories in Brazil's north and southeast. However, the distribution of occurrences reveals

Approaching the Miocene Climatic Optimum in Patagonia (Southern Argentina): Temperature Seasonality and a Potential Role for the Opening Drake Passage

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract The Miocene Epoch (23.03–5.33 Ma) is receiving increased attention because estimated pCO2 and its associated warmth is comparable to projections over the next century. Well‐constrained sea‐surface temperatures in the tropics and northern latitudes express amplified warming during the Miocene Climatic Optimum (MCO; 16.9–14.7 Ma), yet data from ...
