Relative impact of a seagrass bed and its adjacent epilithic algal community in consumer diets
The aim of this work was to identify and compare, using nitrogen and carbon stable isotope data, the food sources supporting consumer communities in a Mediterranean seagrass bed with those in an adjacent epilithic alga-dominated community.
Marine mammals from the southern North Sea: feeding ecology data from δ13C and δ15N measurements
Fin whales, sperm whales and white-sided dolphins are 13 C-depleted compared toSouthern North Sea particulate organic matter and species, suggesting that despite regular sightings, they do not feed within the southern North Sea area.

Ingested artificial fibers of various sizes and colors were found in 27.6% of the digestive tracts of the nine dominant species regardless of their trophic level or taxon and Raman spectroscopy revealed that the ingested AFs were composed of viscose, an artificial, cellulose-based polymer.

Amphipod stable isotope ratios correspond fairly accurately to the trophic classification based on gut contents and attest to their wide spectrum of feeding types, which indicates that there would be no significant changes in feeding strategies over time.

Assessment of gestation, lactation and fasting on stable isotope ratios in northern elephant seals (Mirounga angustirostris)
These processes in simultaneously fasting and lactating northern elephant seals were investigated to determine their impact and limited changes in isotopic signatures of maternal blood over the lactating period were highlighted.
