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

open access: yesJournal 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

open access: yesJournal 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.

Effects of Pre‐Bedtime Social Media Use on Objective and Subjective Sleep Quality in Adolescents and Young Adults

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Using smartphones, particularly social media, before bedtime has emerged as a concern for sleep. While previous research has predominantly focused on total screen time or light exposure, less is known about content‐specific effects. Furthermore, most studies rely on self‐reported data. This study investigated the impact of objectively assessed

Sleep Reorganization and Sustained Attention Following Group Nap Cessation in Japanese Preschoolers

open access: yesJournal of Sleep Research, EarlyView.
Following cessation of routine group napping, preschool children showed increased nighttime sleep but reduced total sleep time. Greater increases in nighttime sleep were associated with fewer sustained attention errors, highlighting the importance of considering individual developmental readiness when transitioning away from daytime naps.

Rhythmic Characterisation of Extreme Circadian Preferences in Everyday Life

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT The aim of this study was to compare extreme circadian preferences by analysing motor activity rhythms in a naturalistic environment. Overall, 84 participants (64 females, 20 males) (42 evening types and 42 morning types), with a mean age of 23.3 years (standard deviation = 4.2), were selected for this study.
