Within-guild dietary discrimination from 3-D textural analysis of tooth microwear in insectivorous mammals. [PDF]
J Zool (1987), 2013 Resource exploitation and competition for food are important selective pressures in animal evolution. A number of recent investigations have focused on linkages between diversification, trophic morphology and diet in bats, partly because their roosting ...

Similar associations of tooth microwear and morphology indicate similar diet across marsupial and placental mammals. [PDF]
PLoS ONE, 2014 Low-magnification microwear techniques have been used effectively to infer diets within many unrelated mammalian orders, but the extent to which patterns are comparable among such different groups, including long extinct mammal lineages, is unknown ...

Digital analysis of tooth microwear, a potential application for dental microwear monitor [PDF]
Biosurface and Biotribology, 2022 In general, tooth wear is difficult to be noticed until it leads to toothache in vivo. Developing a dynamic dental wear monitoring system to predict tooth wear in daily life is a necessity.

Dental microwear texture analysis along reptile tooth rows: complex variation with non-dietary variables [PDF]
Royal Society Open Science, 2021 Dental microwear texture analysis (DMTA) is a powerful technique for reconstructing the diets of extant and extinct taxa. Few studies have investigated intraspecific microwear differences along with tooth rows and the influence of endogenous non-dietary ...

Tooth microwear formation rate in Gasterosteus aculeatus. [PDF]
J Fish Biol, 2014 Tooth microwear feature densities were significantly increased in a population of laboratory-reared three-spined stickleback Gasterosteus aculeatus in four days, after they were transferred from a limnetic feeding regime to a benthic feeding regime ...

Diet reduces the effect of exogenous grit on tooth microwear [PDF]
Biosurface and Biotribology, 2020 Exogenous grit adherent to the surface of food items and food fracture properties have each been considered important factors contributing to pattern and degree of tooth wear in mammals.

Reconstruction of feeding behaviour and diet in Devonian ctenacanth chondrichthyans using dental microwear texture and finite element analyses [PDF]
Royal Society Open ScienceDevonian ctenacanth chondrichthyans reached body sizes similar to modern great white sharks and therefore might have been apex predators of the Devonian seas.

Multi-proxy dentition analyses reveal niche partitioning between sympatric herbivorous dinosaurs [PDF]
Scientific Reports, 2022 Dentitions of the sympatric herbivorous dinosaurs Hungarosaurus (Ankylosauria, Nodosauridae) and Mochlodon (Ornithopoda, Rhabdodontidae) (Santonian, Hungary) were analysed to investigate their dietary ecology, using several complementary methods ...
