Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Framing National Education in Hong Kong: A frame analysis of power dynamics in stakeholders' competing narratives

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
