Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

A description of dental microanatomy and implantation geometry in Chamaeleonidae

open access: yesJournal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

Comparative anatomy of chicken and human forelimb muscles: Implications for human congenital conditions through developmental models

open access: yesJournal of Anatomy, EarlyView.
The chicken embryo is an accessible, low‐cost and genetically tractable model for studying limb development and congenital limb differences. We directly compared chicken and human limb musculature using published evidence alongside our own data and observations.

Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

open access: yesJournal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Integrative architecture and structural boundaries of the subdigital adhesive toe pads of Gekko gecko (Linnaeus, 1758) and guidelines for toe pad demarcation in other geckos

open access: yesJournal of Anatomy, EarlyView.
The adhesively competent toe pads of Gekko gecko (and other geckos) are delimited by a combination of external and deep anatomical features and cannot be identified based upon external scale form alone. We encourage future investigators to delimit toe pads in this functionally and anatomically meaningful fashion.

Founder Effects and Admixture Shape Genetic and Morphological Variation in Non‐Native Populations of the Lizard Anolis cristatellus Introduced From Puerto Rico to Florida

open access: yesJournal of Zoology, EarlyView.
We investigated the evolutionary dynamics in two independent invasions of Anolis cristatellus from Puerto Rico to Miami. We found evidence of reduced genetic variation and increased differentiation consistent with founder events during introduction. Multivariate morphological analyses indicated divergence along different trajectories, consistent with ...
