Stable isotopes of carbon (δ 13 C) and nitrogen (δ 15 N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ 13 C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may alter δ 15 N values. Using nearly 900 skin samples of five cetacean species, this...

The alpine sedge Carex curvula ssp. curvula is a clonal, dominant graminoid found in the European Alps, the Carpathians, the Pyrenees and in some of the Balkan Mountains. It is a late‐successional species of acidophilous alpine meadows that occurs on sites that were covered by ice during the last glacial maximum (LGM). By applying the amplified fragment length polymorphism (AFLP) fingerprinting and chloroplast DNA (cpDNA) sequ...
