Assessment of Formalin-Fixed Bovine Larynx Asymmetry Using Geometric Morphometry. [PDF]

ScientificWorldJournal
The vibrations of the larynx produce the voice. Little is known about morphology and the size of cattle larynx. The aim of the study was to quantify the shape asymmetry of the larynx in calves obtained postmortem using a geometric morphometric approach. A sample of 14 larynges from calves (in an age range 335–625 days) belonging to “Bruna dels Pirineus”

Finding Catalyst Design Principles for Oxygen Evolution using High-Throughput Optimizations and Electrochemical Symmetry. [PDF]

ChemSusChem
Water electrolyzers for green H2 production may be massively used if suitable catalysts for O2 evolution are found. Alas, adsorption‐energy scaling relations have led to uncertain catalyst design heuristics. Here, high‐throughput scaling‐free and scaling‐based optimizations are performed while tracking electrochemical symmetry.

Rare Caudal Regeneration Anomalies in Geckos Are Associated With Global Solar Radiation Gradients

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Morphological abnormalities may reduce fitness in wild animals, making them ecologically relevant for conservation efforts. Anomalies, such as a bifurcation or a trifurcation of a regenerated gecko tail, can change locomotion, social signalling, and predator evasion, with potential effects on survival and reproductive success.

When conservation meets contagion: Mapping yellow fever risk to guide vaccination in an endangered primate

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Spatial projections revealed high‐risk areas for YF transmission, highlighting priority zones for targeted vaccination efforts in GLTs. By integrating disease ecology into conservation planning, this study offers a scalable framework for spatially informed interventions aimed at mitigating disease‐driven declines in threatened species.

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

Austral 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

Journal 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

Evolutionary 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

Small 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

Integrative 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

ChemistrySelect, 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.
