Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology

Austral 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.

Toward an integrated model of geological evolution for NE Brazil-NW Africa: The Borborema Province and its connections to the Trans-Saharan (Benino-Nigerian and Tuareg shields) and Central African orogens

Brazilian Journal of Geology, 2020
Both the Borborema Province of NE Brazil and the geological provinces of NW Africa (the Trans-Saharan Orogen consisted of the Tuareg and Benino-Nigerian shields and the Central African Orogen of Cameroon, Chad, and Central African Republic) are complex ...

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

Ecological Entomology, Volume 51, Issue 3, Page 502-516, June 2026.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 369-389, June 2026.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.

Through the Prism of eDNA: Exploring Cryptic Freshwater Bivalves Diversity in a Mega‐Diverse Tropical Environment

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Extensive eDNA sampling in remote tropical rivers revealed six new species, two of which were later confirmed through traditional surveys and formally described. eDNA also captured basin‐scale haplotype diversity, showing that pristine upstream areas harbor both more species and higher genetic diversity than sites affected by human activities ...
