Isotope signatures & carbon and nitrogen content in Kaltenborn

Dataset Abstract

In summer 2011, we sampled sunlit leaves and needles from a subsample of dominant trees from each species (oak, beech, spruce & douglas) in the Kaltenborn site. These samples were oven drier for 48h at 60°C at INRA nancy. They were grinded and analyzed for oxygen and carbon isotope composition, and total carbon and nitrogen content at UC Davis (USA).

Dataset Design

we sampled leaves and
needles from four trees per species and per plot in monocultures
(n = four plots), two-species mixtures (n = 6), three-species
mixtures (n = 4) and four-speciesmixtures (n = 1). In each
plot, we only took samples from trees at the corners of the
patches. The samples were oven-dried at 60°C for 48 h, then
finely ground. d13C analysis was carried out at the Stable Isotope
Facility of UC Davis, USA.
