High-Resolution in vivo Imaging of Xylem-Transported CO2 in Leaves Based on Real-Time 11C-Tracing
Frontiers in Forests and Global Change, 2019 Plant studies using the short-lived isotope 11C to label photosynthate via atmospheric carbon dioxide (CO2), have greatly advanced our knowledge about the allocation of recent photosynthate from leaves to sinks.

Astronomische Nachrichten, 2014 AbstractThe measurement of isotopic ratios provides a privileged insight both into nucleosynthesis and into the mechanisms operating in stellar envelopes, such as gravitational settling. In this article, we give a few examples of how isotopic ratios can be determined from high‐resolution, high‐quality stellar spectra.

Mass-spectrometric research of ion sputtering processes at high primary ion energies [PDF]
Журнал нано- та електронної фізики, 2009 The article is devoted to mass-spectrometric investigation of ion sputtering processes in a wide range of primary ion energies. For this purpose a design of the secondary neutral mass-spectrometer is developed, which unlike the traditional devices of the

Nature versus nurture? Consequences of short captivity in early stages
Ecology and Evolution, 2018 Biological changes occurring as a consequence of domestication and/or captivity are not still deeply known. In Atlantic salmon (Salmo salar), endangered (Southern Europe) populations are enhanced by supportive breeding, which involves only 6 months of ...

Winter locations of red‐throated divers from geolocation and feather isotope signatures
Ecology and Evolution, 2022 Migratory species have geographically separate distributions during their annual cycle, and these areas can vary between populations and individuals. This can lead to differential stress levels being experienced across a species range.
