“…hare) or likely non‐migratory (e.g. bison, horse, ibex) mammals in our assemblage, while reindeer (Britton, 2010) and mammoth (Wooller et al , 2021) presumably migrated over greater distances and could therefore also reflect the isotopic signatures of a broader geographical range. However, it is a matter of debate whether reindeer migration took place in Europe in every region and at every time during the last glacial period (Fontana, 2017).…”

“…In the evaluation and discussion, only bone collagen data are considered, as the values of dental collagen can be considerably enriched in 15 N compared with bone collagen, which has been confirmed for dental collagen from reindeer (Fizet et al , 1995; Britton, 2010). In addition to bone collagen analyses from KG–AH 2, four samples from KG–AH 1 were analysed, but these results are not included in the discussion, as it cannot be excluded that they originate from a Magdalenian, i.e.…”

We investigated palaeofood web structures using stable isotope analyses on animal bone collagen from four Upper Palaeolithic sites dated to the Early Gravettian (Krems‐Hundssteig and Krems‐Wachtberg: 33–31k cal a bp, Langenlois: 31–29k cal a bp) and to the Early Epigravettian (Kammern‐Grubgraben: 24–20k cal a bp). In both periods, δ13C values show niche partitioning between hare, horse and mammoth on one side, and reindeer and ibex on the other, indicating different diets and habitats between both herbivore groups. The δ15N differences between carnivores and herbivores suggest a difference of one trophic level during the pre‐Last Glacial Maximum (pre‐LGM) period at the Early Gravettian sites and a tendency towards secondary carnivores during the LGM at Kammern‐Grubgraben. δ15N values of pre‐LGM mammoths are elevated in relation to other herbivores but shifted to the level of other herbivores in the LGM. A general δ15N value shift in herbivores of 3.3‰ from the pre‐LGM to the LGM is related to climatic deterioration. This may have led to the disappearance of certain ecological niches and to a shift from broader to overlapping ecological herbivore niches shortly before the LGM, as demonstrated by SIBER analyses.
