Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Evaluation of genetic diversity of Chrysanthemum germplasm resources based on floral phenotypic traits

open access: yesOrnamental Plant Research
Chrysanthemum germplasms are valued for their beauty as an ornamental plant and are increasingly recognized as a source of medicinal products. The floral traits of Chrysanthemum × morifolium are of considerable importance and exhibit substantial genetic ...

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

More‐than‐gender? Moving beyond gendered expectations of divergent learners in early childhood education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In this paper, we explore how neurodivergent ways of being in early education are often gendered. The intersectionalities of gender and neurodivergence often lead to fixed expectations that perpetuate binary interpretations, pathologisations, missed diagnoses and a lack of curated support.

Understanding Plant Parasitism: Hydnora Africana and European Scientific Practice in the Early Nineteenth Century**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
This article will analyze the uncertainties around collecting and classifying Hydnora africana in the first half of the nineteenth century. Emerging from the distinctive dryland ecologies of South Africa, Hydnora was interpreted as strange and cryptic by Europeans primarily because it is a root parasite—a complex floral trait that was little understood.
