The Genus Hyalyris Boisduval, 1870 (Lepidoptera: Nymphalidae) in the Brazilian Atlantic Forest: Systematics, Taxonomy and Conservation

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT The neotropical butterfly tribe Ithomiini (Danainae) comprises about 400 species distributed from Mexico to Northern Argentina, 58 of which occur in the Brazilian Atlantic Forest. Among these are two species assigned to the genus Hyalyris Boisduval, 1870: Hyalyris fiammetta (Hewitson, 1852) and Hyalyris leptalina (C. Felder & R. Felder, 1865).

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

open access: yesJournal of Zoology, Volume 329, Issue 1, Page 25-37, May 2026.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Re‐Interpreting Genetic Offset: Quantifying the Least Required Evolutionary Rate Under Climate Change at the Mediterranean Range Margin of European Beech

open access: yesEvolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT European beech (Fagus sylvatica L.) spans a wide range of European climates and exhibits evidence of local adaptation, which supports its persistence under diverse conditions. We analysed 18 populations—distributed across an altitude gradient on the southwestern geographic range edge of the species—using landscape genomics to assess their ...

Building Single‐Atom and Single‐Cluster Metal Catalysts Supported on Graphdiyne and Boron‐Graphdiyne

open access: yesSmall Structures, Volume 7, Issue 1, January 2026.
Single‐atom catalysts, SAC, and single‐cluster catalysts, SCC, are designed through the deposition of transition metal atoms and clusters on layered graphdiyne, GDY, and boron‐graphdiyne, BGDY. The metal atoms and clusters bind strongly to the nanopores of GDY and BGDY and high activation barriers for diffusion of the metal atoms prevent metal ...

Climate and Socio‐Sexual Environment Predict Interpopulation Variation in Chemical Signaling Glands in a Widespread Lizard

open access: yesIntegrative Zoology, Volume 20, Issue 6, Page 1215-1226, November 2025.
High phenotypic variation in femoral pore number across 55 populations of Podarcis muralis is best explained by a combination of positive allometry (size) and the local intensity of sexual selection (sexual dimorphism in body size, SSD) or local climatic conditions, notably temperature and vegetation density.

Comprehensive Molecular Modeling Analysis of Betulin, a Triterpene Isolated from Miconia burchellii (Melastomataceae) Native to the Brazilian Cerrado

open access: yesChemistrySelect, Volume 10, Issue 40, October 27, 2025.
Betulin, isolated from the Brazilian Cerrado plant Miconia burchellii, was comprehensively characterized using X‐ray diffraction, DFT, and molecular modeling. Solid‐state analysis revealed stabilizing O···H and H···H contacts, while DFT calculations (HOMO–LUMO gap: 9.38 eV) indicated moderate stability.
