Optimization of Turbidity Removal in Water Using Chemically Modified Tannins From Brazilian Species

open access: yesWater Environment Research, Volume 98, Issue 6, June 2026.
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

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
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

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
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.

VARIAÇÃO, DIVERGÊNCIA E CORRELAÇÕES GENÉTICAS ENTRE CARACTERES SILVICULTURAIS E DENSIDADE BÁSICA DA MADEIRA EM PROGÊNIES DE Myracrodruon urundeuva (Engler) Fr. Allem

open access: yesRevista do Instituto Florestal, 2011
Myracrodruon urundeuva foi muito explorada no passado devido às qualidades de sua madeira e tornou-se escassa em todas as áreas naturais de ocorrência, sendo atualmente considerada como ameaçada de extinção (categoria vulnerável).

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
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.

Assessing group size and the demographic composition of a canopy‐dwelling primate, the northern muriqui (Brachyteles hypoxanthus), using arboreal camera trapping and genetic tagging

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 226-241, April 2026.
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

open access: yesApplied Vegetation Science, Volume 29, Issue 2, April/June 2026.
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 ...
