Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Overnight Dynamics of Ventricular Cerebrospinal Fluid Amyloid‐Beta, Lactate and Hypocretin in Patients With Hydrocephalus: A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT This pilot observational study evaluated whether frequent overnight sampling of ventricular cerebrospinal fluid could clarify how sleep, hypocretin and lactate relate to amyloid‐β42 dynamics in adults with hydrocephalus. Seven participants underwent hourly ventricular cerebrospinal fluid sampling from early evening to late morning during ...

Weighing the options: a test of alternative stomatal optimisation models at high temperatures

New Phytologist, EarlyView.
Summary Stomatal optimisation models centre upon a fundamental tradeoff for plants: opening stomata promotes carbon uptake, but closing stomata prevents water loss. However, stomatal opening can occur at high temperatures, causing evaporative cooling which limits thermal damage to leaves.

Subnational Border Reforms and Economic Activity in Africa

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT Using GIS methods, we identify territories in Africa affected by subnational border reforms between 1992 and 2013. Descriptive statistics reveal that these territories differed from other African regions across several key dimensions. For example, these territories were more populous and exhibited greater ethnic diversity.
