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.

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.

Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Selective metasomatism of ultramafic cumulates within Archean supracrustal sequences
The Neoarchean Storø Supracrustal Belt in SW Greenland comprises a sequence of mature quartzite, metapelite, amphibolite, and ultramafic rocks that underwent amphibolite facies metamorphism during the amalgamation of the Mesoarchean Akia Terrane and the ...

Journal of Biogeography, Volume 53, Issue 6, June 2026.ABSTRACT Aim Carex section Echinochlaenae has a disjunct distribution across the Southern Hemisphere. It displays a clear center of diversity in New Zealand coupled with extreme morphological and ecological diversification, suggesting a potential evolutionary radiation.
