Warming Has Limited Effects on Carbon‐Use Efficiency of Wheat and Upland Rice Plants—Evidence From a 13CO2 Labelling Study

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant carbon‐use efficiency (CUE) is a key parameter quantifying the net carbon gain with respect to gross carbon fixation. Although it is critical for carbon cycle models, it is often assigned an empirical value due to measurement difficulty. Uncertainty remains whether CUE is affected by warming. We quantified CUE in wheat (Triticum aestivum)

VUV and mid‐UV photoabsorption cross sections of thin films of glycine and alanine: Application to their photochemistry in the solar system

Photochemistry and Photobiology, EarlyView.
Thin solid films of pure glycine or alanine (thicknesses ranging from 10 to 700 nm) were prepared on MgF2 windows using a vacuum sublimation/recondensation method. VUV‐UV spectroscopy of these films enabled us to characterize new absorption cross sections for glycine and alanine for VUV‐UV radiations between 120 and 300 nm.

Integrating natural baselines into ecosystem restoration: scaling herbivore targets for European landscapes

Restoration Ecology, EarlyView.
Abstract Introduction Herbivore‐mediated ecosystem processes are fundamental to biodiversity, yet have been greatly diminished by megafauna extinctions and replacement of wild herbivores by managed livestock. With increasing restoration ambitions—including the United Nations' (UN) Decade on Ecosystem Restoration and the European Union (EU) Nature ...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Creatine and cognitive function: Why has physiological plausibility not translated into convincing clinical evidence?

Experimental Physiology, EarlyView.
Abstract Creatine is among the most extensively studied and widely used nutritional supplements in sports and exercise science. Over the past two decades, however, interest has expanded well beyond skeletal muscle, driven by growing recognition of the central role played by the creatine–phosphocreatine system in cerebral bioenergetics.
