Spliceosome protein alterations differentiate hubs of the default mode connectome during the progression of Alzheimer's disease

Brain Pathology, Volume 35, Issue 5, September 2025.
Default mode network (DMN) consists, in part, of the frontal (FC), precuneus (PreC), and posterior cingulate cortex (PCC), which plays a critical role in episodic memory and retrieval of autobiographical memories, displays spatiotemporal differences in the onset of amyloid and hypometabolism that reflects tau neurodegeneration and loss of connectivity ...

Territory Size but Not Territorial Defence Varies With Habitat Quality and Competitor Density in a Farming Species

Ethology, Volume 131, Issue 9, Page 65-76, September 2025.
Algal‐farming damselfish in high‐quality habitats with more neighbours and smaller territories did not differ in their defence costs to those in poorer habitats with larger territories and fewer neighbours. While overall intrusion and attack frequencies were similar between these two habitat areas, territory holders interacted differently with ...

Biotic Mechanisms Strengthen Functional and Phylogenetic Convergence of Reef Fish Assemblages at Higher Latitudes

Journal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim How communities of organisms come together has long fascinated scientists, with renewed interest in using functional and evolutionary patterns to infer mechanisms of community assembly. Ecological theory predicts that biotic interactions could lead to either divergence in the event of niche partitioning or convergence through the exclusion
