Simulated isotopic fingerprint of the Atlantic Multidecadal Oscillation over South America and its relation to the Little Ice Age.
Linkages have been established between the Atlantic Multidecadal Oscillation (AMO) and surface air temperature variations, low-level jet streams, and precipitation trends in both northeastern Brazil and southeastern South America. Previous studies have discerned distinct wet-season (MarchMay) precip...

Evaluation of easterly wave disturbances over the tropical South Atlantic in CMIP6 models.
This study assesses the performance of the latest phase of Coupled Model Intercomparison Project (CMIP6) models in simulating easterly wave disturbances (EWD) over the tropical South Atlantic (TSA) impacting northeast Brazil (NEB). Initially, we evaluate simulated precipitation from 17 historical CM...

Regional relationship between total alkalinity and salinity in the surface waters of the western South Atlantic margin.
We examined the surface total alkalinity (AT) and salinity (SSS) distributions and their relationship along the southwestern South Atlantic Ocean margin off the Brazilian coast. In situ hydrographic data from shelf and slope stations were measured during three oceanographic cruises in October 2014 (...

Potential effects of climate change on cacti distribution and conservation in North American drylands.
Climate change is expected to adversely impact dryland biodiversity by reducing habitat suitability, especially for cacti species. One way to mitigate such effects on cacti is to reinforce the integrity of areas of high importance for their conservation, also known as high-value conservation areas (...
