Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

open access: yesCladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

To release or not to release? Understanding sawfish release behavior in a global south complex fishery

open access: yesConservation Science and Practice, EarlyView.
This demonstrates the gap between existing top‐down laws and strategies (Current Approach) and the barriers fishers face while proposing an alternative pathway (Proposed Approach) based on collaboration, capacity building, and addressing socio‐economic factors.

Traditional serrated adenoma of the colorectum: Evolving concepts in histological classification and terminology

open access: yesHistopathology, EarlyView.
The definition of the colorectal traditional serrated adenoma (TSA) has evolved to recognize a broader morphological spectrum, including classical, flat and mixed lesions reflecting early development and neoplastic progression. Updated WHO classification highlights the need for consistent terminology to improve recognition and to distinguish TSA from ...

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

open access: yesJournal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Somatic Mosaic AXIN2‐associated Colonic Polyposis Predominantly Involving the Proximal Colon: A Case Report

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Colonic adenomatous polyposis is most commonly caused by germline pathogenic variants in the APC gene; however, recent genetic studies have identified patients without APC mutations. AXIN2‐associated colonic polyposis is a rare condition related to dysregulation of the Wnt/β‐catenin signaling pathway. Most reported cases have involved germline
