Analogue modelling of basin inversion: the role of oblique kinematics and implications for the Araripe Basin (Brazil)

, 2022
Abstract. Basin inversion is a process that takes place when a sedimentary basin is subjected to compressional stresses and may result in the reactivation of pre-existing faults and/or the localization of deformation along new reverse faults. The Araripe Basin (NE Brazil) is an example of a Cretaceous intracontinental aborted rift with its sedimentary ...

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

Freshwater 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 ...

Aptian/Albian (Early Cretaceous) paleogeography of the South Atlantic: a paleontological perspective

Brazilian Journal of Geology
Paleontological data obtained in recent years reinforce the hypothesis that Aptian marine sedimentation in the sedimentary basins of the Brazilian continental margin - except the Pelotas basin, the southernmost Brazilian basin - took place under the ...

Meso and microscopic characterization of deformation bands in porous sandstones: an example on the Paleozoic, Pre- and Sin-rift sequences of the Araripe Basin, Northeast of Brazil [PDF]

Geologia USP. Série Científica, 2012
Deformation bands are narrow tabular volumes developed in porous sandstones. Although these structures are a product ofbrittle deformation, they may have internally a continuous displacement gradient.

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

Papers 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

Water 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 ...
