Environmental and seasonal filtering of taxonomic, functional and phylogenetic diversity patterns of mountain butterflies in a prime butterfly area, Greece

open access: yesInsect Conservation and Diversity, EarlyView.
Forest clearings support butterfly communities comparable to mountainous grasslands in alpha‐diversity and conservation value, yet remain compositionally distinct. Generalized linear models (GLMs) showed three key habitat predictors shaping multifaceted diversity and community composition: herb/grass height, flowerhead abundance and elevation.

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

open access: yesSedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Sedentary ageing remodels the structure–function relationships that underlie calcium signalling at super‐resolution scales in the heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Illustration of calcium spark function and ryanodine receptor (RyR) structure within a sedentary model of ageing. Upon sympathetic stimulation from 1 µM isoprenaline a linear response to calcium spark morphology occurred, accompanied by a biphasic progression of RyR remodelling across age.

A Super‐Resolution Approach for Astrocyte‐Specific Molecular Imaging Reveals the Nanoscale Distribution of Monoacylglycerol Lipase, the Metabolic Node Between Endocannabinoid and Prostaglandin Signaling

open access: yesGlia, Volume 74, Issue 9, September 2026.
Dual‐color STORM resolves the precise architecture and protein distributions within hippocampal astrocytes at the nanoscale. Identification of a sparse but specific MAGL pool in CA1 astrocytic processes. Astrocytic MAGL is not synapse‐associated, suggesting a synapse‐independent role.

Dorso‐Ventral and Night‐Day Regulation of Extracellular K+ Dynamics in Mouse Hippocampal Astrocytes

open access: yesGlia, Volume 74, Issue 9, September 2026.
Hippocampal astrocytic K+ buffering varies by region and time. Ventral astrocytes show faster K+ accumulation due to reduced Kir4.1 function. Such regional divergence is modulated by circadian shifts in Kir4.1 and gap junction coupling. ABSTRACT Astrocytes regulate extracellular potassium (K+) through multiple mechanisms operating across distinct ...
