Improving the Prediction of Treefrog Species Vulnerability to Climate Change: The Role of Abundance

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim As climate changes intensify over time due to anthropogenic pressures, it is estimated that a global shift in the current biodiversity patterns, including the loss of several species. Amphibians are the most threatened group by climate change and, in addition to distribution shifts, declines in species abundances are also expected.

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

open access: yesJournal of Fish Biology, Volume 109, Issue 1, Page 146-164, July 2026.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Export Promotion With Matchmaking and Grants: Evidence From Portuguese Firms

open access: yesThe World Economy, Volume 49, Issue 7, Page 1498-1518, July 2026.
ABSTRACT This paper evaluates two core export‐promotion tools: internationalization grants and matchmaking services provided by the Portuguese export promotion agency (AICEP). We merge administrative records with customs and firm data for 2012–2021. We employ an event‐study approach with firm and year fixed effects in a setup of staggered adoption of ...

Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the
