abstract = {{Here we present stable carbon, nitrogen and sulfur isotope ratios of collagen extracted from Rangifer, Equus and Bison bone (n {\textequals} 128) from different stratigraphic levels at the chronologically well-constrained Middle and Upper Palaeolithic site of Les Cott{\'e}s, France. Samples were taken from five phases of site use (US08, US06, US04 [upper and lower], and US02; {\textasciitilde} 45.8{\textendash}35.3 ka cal BP) to explore the dietary and spatial palaeoecology of these ungulate species during MIS 3, and the contemporary climate. Temporal trends in $\delta$15N values of all species broadly align with other climatic indicators at the site and the lowest values in US04 correspond to the Heinrich 4 cooling event, reflecting changes in the composition of soil/plant nitrogen at this time. Rangifer collagen is 13C-enriched compared to the other species throughout, consistent with lichen consumption. However, this isotopic niche partitioning between Rangifer and Equus/Bison is most extensive during US04, indicating plasticity in reindeer feeding behaviour, and potentially overall increased lichen biomass during this cooler/more arid phase. Rangifer $\delta$34S values are consistently lower than Equus and Bison, which could be indicative of their more extensive spatial ranges incorporating greater inland areas. Equus and Bison demonstrate a significant decrease in $\delta$34S values through time, which may be linked to contemporary climatic decline.}},
