3D dental microwear texture analysis of feeding habits of sympatric ruminants in the Białowieża Primeval Forest, Poland
چکیده انگلیسی


• 3D-dental microwear textural analysis mirrors feeding habits of ruminants.
• 3D-DMTA emphasizes the dietary overlapping among cervids from Białowieża Forest.
• 3D-dental microwear textural analysis pinpoints mixed feeding habits for the European bison.
• Diet of the bison changes seasonally and depends on the winter supplementary feeding intensity.

With four species of ruminants, including red deer, roe deer, moose, and European bison, the Białowieża Primeval Forest is unique on the European continent, where only one to three ungulate species are usually found. The present study is the first effort to explore the dietary overlap of a European community of sympatric ruminants using 3D dental microwear texture analysis. Results obtained for ungulates from the Białowieża Forest were compared with those of four species with well known differences in diet (semi-wild Heck cattle, African buffaloes, giraffes, and yellow-backed duikers). These ruminants frame the spectrum of expected 3D dental microwear textures among ruminants: C3 and C4 grazers share high anisotropy and low to intermediate complexity while browsers display intermediate to high complexity associated with low anisotropy. No significant differences between browsers (moose and roe deer) and mixed feeders (red deer) were detected by this analysis supporting a significant overlap in diet found in Białowieża. The results on the fourth ruminant are unequivocal: the European bison is not grazer but instead is highly engaged in browsing. Furthermore, through 3D dental microwear texture analysis, the high plasticity in feeding behavior of the European bison can be tracked depending on the seasons and on available access to feeding supplements during the winter.
