The interplay between basement fabric, rifting, syn‐rift folding, and inversion in the Rio do Peixe Basin, NE Brazil

open access: yesBasin Research, Volume 35, Issue 1, Page 61-85, February 2023., 2023
3D evolutionay diagram showing the evolution of the Rio do Peixe Basin and the relationship between the Precambrian basement fabric (a) with the nucleation and orientation of the main syn‐rift normal faults (b) and the subsequent syn‐rift folding (c) over steps and/or curvatures in normal fault geometries.

Seaward‐Dipping Reflector Influence on Seafloor Magnetostratigraphy—A Pelotas Basin View

open access: yesGeophysical Research Letters, Volume 49, Issue 23, 16 December 2022., 2022
Abstract Previous works used marine magnetic survey data and interpreted magnetic anomalies related to seaward‐dipping reflectors (SDRs) as oceanic crust or SDR age constraints in the South Atlantic Ocean. However, we advise against using SDR‐related magnetic anomalies to constrain ages because of the mostly low‐dipping geometry causing the overlapping

Fisheries management influences phytoplankton biomass of Amazonian floodplain lakes

open access: yesJournal of Applied Ecology, Volume 58, Issue 4, Page 731-743, April 2021., 2021
Tropical freshwaters fisheries typically assume that fish biomass is controlled by bottom‐up mechanisms, so that overexploitation of large predators would not affect overall ecosystem productivity. Our results, however, show that top‐down forces are important drivers of primary productivity in tropical lakes, above and beyond the effects of bottom‐up ...

Tough fishing and severe seasonal food insecurity in Amazonian flooded forests

open access: yesPeople and Nature, Volume 2, Issue 2, Page 468-482, June 2020., 2020
Abstract Billions of people rely on harvesting wildlife for food, and must contend with catch rates that vary in space (e.g. overharvesting near communities) and time (e.g. seasonal migrations). Yet, research has overlooked potential linkages between reduced wildlife catch rates (catch‐per‐unit‐effort) and food security.

Tectonic Framework and Low‐Oblique Rifting Kinematics of the Campos Basin, Southeastern Brazilian Margin

open access: yesTectonics, Volume 44, Issue 6, June 2025.
Abstract Understanding the tectonic framework of extensional margins is fundamental to unraveling kinematics, basement inheritance and magmatism during rifting. Using regional gravity and magnetic surveys, 2D and 3D seismic reflection data and well information in the Campos Basin, we conducted a systematic structural mapping of the syn‐rift building ...

Crustal Architecture and Magmatism of the Campos Rifted Margin: Along‐Strike Variability and Segmentation

open access: yesTectonics, Volume 43, Issue 12, December 2024.
Abstract We investigate the crustal architecture and structural domains of the Campos rifted margin in southeastern Brazil, focusing on rifting evolution and segmentation. Based on 2‐D and 3‐D seismic reflection interpretation and potential field modeling, our results reveal an along‐strike variability, in terms of margin architecture and magmatism ...
