Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Global length–weight relationships of deep‐pelagic fishes: Coverage, biases and variability

Journal of Fish Biology, EarlyView.
Abstract Length–weight relationships (LWRs) are morphometric tools that allow body mass to be estimated from fish length, providing input for fisheries, ecological and biodiversity studies. For deep‐pelagic fishes, however, LWR data remain fragmented and unavailable for most species.

A phylogenomic approach for a new infrageneric classification of Bulbostylis (Abildgaardieae, Cyperaceae)

Journal of Systematics and Evolution, EarlyView.
In this study, we investigate the relationships among 149 species of Bulbostylis (Cyperaceae)—representing 69% of global diversity—using a universal probe kit for targeted genomic sequencing of flowering plants (Angiosperms353 probe kit). Our sampling also includes the genus Nelmesia, which we found to fall within Bulbostylis.

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.
