Shell-bound organic matter (SBOM) is present in the shells of biomineralizing organisms and can act as an isotopic proxy for nutrition. Stable isotope analysis of SBOM generally requires its isolation from the mineral component of the shell, and this

Using plant wax markers to estimate the diet composition of grazing Holstein dairy cows

Autor: C Heublein, Fiona L. Gill, Frigga Dohme-Meier, Fredy Schori, Karl-Heinz Südekum

The objective of this study was to test whether diet selection of dairy cows under grazing conditions could be estimated using plant wax markers. Furthermore, differences between 2 cow strains and the effect of concentrate supplementation on plant sp

The Arctic is melting at an unprecedented rate and key drivers are changes in snow and ice albedo. Here we show that red snow, a common algal habitat blooming after the onset of melting, plays a crucial role in decreasing albedo. Our data reveal that

Dung from a mammoth was preserved under frozen conditions in Alaska. The mammoth lived during the early part of the Late Glacial interstadial (ca 12,300 BP). Microfossils, macroremains and ancient DNA from the dung were studied and the chemical compo

The aim of the present experiment was to compare silage prepared from maize having a brown midrib (BMR) mutation with control (CTR) maize to identify their effects on enteric methane emission, digesta mean retention time (MRT), ruminal fermentation a
