Optimization of Turbidity Removal in Water Using Chemically Modified Tannins From Brazilian Species
Cationized tannins from Stryphnodendron adstringens and Mimosa tenuiflora efficiently removed water turbidity under optimized conditions. These natural coagulants demonstrated nearly 100% clarification, offering sustainable alternatives for water treatment.

Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology
ABSTRACT Understanding the factors shaping species distribution is a key challenge in ecology and biogeography. While dispersal limitations, environmental features, and biotic interactions are commonly recognized as key determinants of species abundance and distribution, some species exhibit patchy distributions that remain hard to explain.

Soybean yield performance in oxisols with varying morphological and physicochemical characteristics
Abstract Soybean (Glycine max (L.) Merril) yield in tropical high‐altitude regions is strongly influenced by soil physical and chemical attributes, particularly in highly weathered oxisols, where variability among suborders may affect crop performance.

Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...

The Blue List Initiative: Guiding Biodiversity Restoration in Brazil's Espinhaço Range
The campo rupestre is a biodiversity hotspot marked by extreme habitat heterogeneity and high species turnover. Using phytosociological data, floristic clustering and zeta diversity, we show that habitats are floristically non‐interchangeable and propose habitat‐ and substrate‐specific Blue Lists to guide effective, locality‐based ecological ...
