“…Rabbits share feeding patterns with other mammals whereby items with greater toughness and/or higher stiffness require larger and protracted jaw-adductor forces during biting and chewing, which results in greater occlusal forces and masticatory stresses (e.g., Herring and Scapino, 1973;Weijs and de Jongh, 1977;Hylander, 1979;Gorniak and Gans, 1980;Weijs and Dantuma, 1981;Dessem and Druzinsky, 1992;Hylander et al, 1992Hylander et al, , 1998Hylander et al, , 2000Ravosa and Hogue, 2004;Vinyard et al, 2008). Rabbits are likewise noteworthy due to extensive ontogenetic data about the in vivo links among masticatory function, feeding behavior and food mechanical properties (e.g., Weijs et al, 1987Weijs et al, , 1989Langenbach et al, 1991Martin et al, 2020).…”

Due to their global distribution, invasive history, and unique characteristics, European rabbits are recognizable almost anywhere on our planet. Although they are members of a much larger group of living and extinct mammals [Mammalia, Lagomorpha (rabbits, hares, and pikas)], the group is often characterized by several well-known genera (e.g., Oryctolagus, Sylvilagus, Lepus, and Ochotona). This representation does not capture the extraordinary diversity of behavior and form found throughout the order. Model organisms are commonly used as exemplars for biological research, but there are a limited number of model clades or lineages that have been used to study evolutionary morphology in a more explicitly comparative way. We present this review paper to show that lagomorphs are a strong system in which to study macro- and micro-scale patterns of morphological change within a clade that offers underappreciated levels of diversity. To this end, we offer a summary of the status of relevant aspects of lagomorph biology.

“…By contrast, triggering different wear rates and different mesowear patterns has been more complicated. In rabbits, indicators of absolute wear, mesowear and dental microwear texture showed some correlations that one might expect between tooth height (a proxy for absolute tissue loss in ever-growing teeth), mesowear cusp shape, and microwear texture height and volume parameters, responding to more abrasive wear [35]. In a similar study on guinea pigs [34], tooth height and dentine basin depth correlated negatively, suggesting a sequence of dentine erosion followed by ablation of the surrounding enamel as a wear process.…”

Dietary reconstruction in vertebrates often relies on dental wear-based proxies. Although these proxies are widely applied, the contributions of physical and mechanical processes leading to meso- and microwear are still unclear. We tested their correlation using sheep ( Ovis aries , n = 39) fed diets of varying abrasiveness for 17 months as a model. Volumetric crown tissue loss, mesowear change and dental microwear texture analysis (DMTA) were all applied to the same teeth. We hereby correlate: (i) 46 DMTA parameters with each other, for the maxillary molars (M1, M2, M3), and the second mandibular molar (m2); (ii) 10 mesowear variables to each other and to DMTA for M1, M2, M3 and m2; and (iii) volumetric crown tissue loss to mesowear and DMTA for M2. As expected, many DMTA parameters correlated strongly with each other, supporting the application of reduced parameter sets in future studies. Correlation results showed only few DMTA parameters correlated with volumetric tissue change and even less so with mesowear variables, with no correlation between mesowear and volumetric tissue change. These findings caution against interpreting DMTA and mesowear patterns in terms of actual tissue removal until these dental wear processes can be better understood at microscopic and macroscopic levels.

“…in the Liberian chimpanzees, probably as a cumulative result of varying dietary properties dominated by low abrasive (a)biotic particles in a long-term perspective [19]. In contrast, more planar and larger wear facets, which are related to a higher rate of tissue loss, point toward a high abrasive diet.…”

“…Both biotic (food) and abiotic (dust) factors lead to dental tissue loss during mastication, which manifests itself macroscopically by generating complementary wear facets on antagonistic occlusal tooth surfaces and microscopically by forming pits/dales and scratches/furrows on these wear facets [e.g. 13,[17][18][19][20]. Therefore, tooth wear analysis has been widely used as a tool for reconstructing diets and environmental changes in living and fossil primates and other mammals, often where primary ecological or environmental data were incomplete or lacking [e.g.…”

“…Yet, both analyses indicated an increased reliance upon tough, fibrous food such as meat [24,37]. In recent feeding experiments on rabbits [19], goats [38], and guinea pigs [39] it has been shown that both increased macroscopic tooth wear and microscopic wear signals (high surface roughness and high mean density of pits and furrows) were positively correlated with the amount, shape and size of internal and external dietary abrasives ingested.…”

Dental wear patterns reveal dietary ecology and season of death in a historical chimpanzee population

Dental wear analyses have been widely used to interpret the dietary ecology in primates. However, it remains unclear to what extent a combination of wear analyses acting at distinct temporal scales can be beneficial in interpreting the tooth use of primates with a high variation in their intraspecific dietary ecology. Here, we combine macroscopic tooth wear (occlusal fingerprint analysis, long-term signals) with microscopic 3D surface textures (short-term signals) exploring the tooth use of a historical western chimpanzee population from northeastern Liberia with no detailed dietary records. We compare our results to previously published tooth wear and feeding data of the extant and continually monitored chimpanzees of Taї National Park in Ivory Coast. Macroscopic tooth wear results from molar wear facets of the Liberian population indicate only slightly less wear when compared to the Taї population. This suggests similar long-term feeding behavior between both populations. In contrast, 3D surface texture results show that Liberian chimpanzees have many and small microscopic wear facet features that group them with those Taї chimpanzees that knowingly died during dry periods. This coincides with historical accounts, which indicate that local tribes poached and butchered the Liberian specimens during dust-rich dry periods. In addition, Liberian females and males differ somewhat in their 3D surface textures, with females having more microscopic peaks, smaller hill and dale areas and slightly rougher wear facet surfaces than males. This suggests a higher consumption of insects in Liberian females compared to males, based on similar 3D surface texture patterns previously reported for Taї chimpanzees. Our study opens new options for uncovering details of feeding behaviors of chimpanzees and other living and fossil primates, with macroscopic tooth wear tracing the long-term dietary and environmental history of a single population and microscopic tooth wear addressing short-term changes (e.g. seasonality).
