Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

open access: yesFreshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

The first pterosaur from the Bauru Group: an azhdarchid from the Upper Cretaceous of Brazil

open access: yesPapers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract The vertebrate fossil record of the Bauru Group (Upper Cretaceous, southeastern Brazil) is remarkably rich, with a predominance of titanosaurs and crocodyliforms, alongside theropods, turtles, squamates, fishes and even small mammals. In contrast, pterosaur remains from the Bauru Group have remained elusive until now.

Opportunities for Translational Water Research in Global Biodiversity Conservation

open access: yesWater Resources Research, Volume 61, Issue 9, September 2025.
Abstract Academic researchers and practitioners in water resources disciplines are calling for solution‐oriented and actionable hydrological science, recently encompassed by the term translational water research (TWR). Here, we argue that the interdisciplinary field of biodiversity conservation science (also known as conservation biology) presents ...

On Northeast Brazil Orographic Enhanced Rainfall and Monsoon Dynamics

open access: yesInternational Journal of Climatology, Volume 45, Issue 10, August 2025.
We provide an updated rainfall climatology (1990–2020) for Northeast Brazil which discusses the role of orographically enhanced rainfall and monsoon dynamics on this climate system. Our work presents strong evidence that this continental‐scale region is under a more extensive influence of the South American Monsoon System than previously described ...

A new angiosperm from the Crato Formation (Araripe Basin, Brazil) and comments on the Early Cretaceous Monocotyledons [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2014
The Crato Formation paleoflora is one of the few equatorial floras of the Early Cretaceous. It is diverse, with many angiosperms, especially representatives of the clades magnoliids, monocotyledons and eudicots, which confirms the assumption that angiosperm diversity during the last part of the Early Cretaceous was reasonably high.

STATISTICAL ANALYSIS OF PALYNOLOGICAL ASSEMBLAGES FROM THE APTIAN-ALBIAN OF THE ARARIPE BASIN, NORTHEAST BRAZIL: A CASE STUDY OF PALEOENVIRONMENTAL SIGNIFICANCE OF EARLY CRETACEOUS TERRESTRIAL PALYNOMORPHS

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
Statistical treatment of palynological data from Rio da Batateira and Santana formations (Aptian-Albian) of the Araripe Basin provides mathematical support to paleoclimatic interpretations.

A new antshrike (Aves: Thamnophilidae) endemic to the Caatinga and the role of climate oscillations and drainage shift in shaping cryptic diversity of Neotropical seasonal dry forests

open access: yesZoologica Scripta, Volume 53, Issue 5, Page 487-508, September 2024.
Abstract The Caatinga is the largest patch of Seasonal Dry Tropical Forest in the Neotropics, located in northeastern Brazil and characterized mainly by deciduous vegetation and extreme rainfall seasonality. It has historically been treated as a biologically impoverished domain, but recent studies uncovered new diversification patterns and several new ...
