Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

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 ...

Flourishing through adventure learning: A (semi)cautionary tale

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Studies suggest that adventure learning can develop children's cognitive skills and promote social and emotional learning. However, evidence is needed as to whether the design of adventure learning—school‐based or external/residential—plays a role in that development/promotion, and whether learning gains are maintained.

What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual
