Strains arising by seismic events in the SIRGAS-CON network region

Journal of Geodetic Science, 2013
In this study, we investigate surface strains related to seismic events and their relationship with pre- and post-seismic events in Latin America, by analyzing the variation of estimated earth coordinates supplied by a geodetic network called SIRGAS-CON.

From Disturbance to Recovery: Unveiling the Role of Goats and Ecological Drivers on Vegetation Dynamics of Trindade Island, South Atlantic, Brazil

Journal of Vegetation Science, Volume 36, Issue 3, May/June 2025.
We analyzed long‐term vegetation dynamics on Trindade Island, assessing the influence of feral goats and abiotic factors using remote sensing and field data. Vegetation cover increased over time, with forests and grasslands expanding. NDVI effectively captured these changes, revealing strong biotic and abiotic interactions.

The GrassSyn dataset: Soil organic carbon stocks in Brazilian grassy ecosystems

Journal of Environmental Quality, Volume 54, Issue 2, Page 335-348, March/April 2025.
Abstract Although ecosystem management and restoration are known to enhance carbon storage, limited knowledge of ecosystem‐specific soil organic carbon (SOC) stocks and processes hinders the development of climate‐ready, biodiversity‐focused policies. Baseline SOC stocks data for specific ecosystems is essential.

Temporal Dynamics of Species Richness and Composition in a Peri‐Urban Tropical Frog Community in Central Brazil

Ecology and Evolution, Volume 14, Issue 11, November 2024.
This study address how species coexistence and species–environment relationship are impacted by temporal variation in climate sub‐urban area. ABSTRACT Analyzing the temporal dynamics of ecological communities can shed light on coexistence mechanisms and help understand how populations and communities will behave in the face of climate change.
