Evolution of hypsodonty in equids: testing a hypothesis of adaptation (2006, methodology): “For example, Janis et al. (2000, 2002, 2004a) and Williams and Kay (2001) recently used an HI (herein HIm3) defined as the unworn m3 height divided by m3 width (Janis 1988), and classified ‘‘brachydont’’ as HIm3 , 1.5, ‘‘hypsodont’’ as a HIm3 .”
Coevolution of Tooth Crown Height and Diet in Oreodonts (Merycoidodontidae, Artiodactyla) Examined with Phylogenetically Independent Contrasts (2006, methodology): “The appearance of numerous hypsodont taxa in the early to middle Miocene suggests that the open grassland biome first appeared around 18Ma in North America (Janis et al., 2002).”
VERTEBRATE DISPERSAL OF SEED PLANTS THROUGH TIME (2004, background): “Subsequent middle Tertiary radiations of “whole-plant” grazers (even-toed and odd-toed ungulates and others) added a further layer of diffuse dispersal relationships (Janis 1993, Novacek 1999, Janis et al. 2002).”
Carbon and oxygen isotopic variability in Neogene paleosol carbonates: constraints on the evolution of the C4-grasslands of the Great Plains, USA (2004, background): “Our second hypothesis returns the focus of grassland origins in the Great Plains to the wellknown pattern of global climatic cooling during the late Cenozoic (Zachos et al., 2001) and suggests that the Pliocene increase in C4 biomass was driven by the ecological consequences of reduced growing seaso”
Forgotten Grasslands of the South: Natural History and Conservation (2012, methodology): “Reprinted from Janis et al. (2002) with the permission of Elsevier.”
The Tinguiririca Fauna, Chile: Biochronology, paleoecology, biogeography, and a new earliest Oligocene South American Land Mammal 'Age' (2003, background): “Numerous authors have demonstrated that aspects of modern mammal faunas are highly correlated with environmental variables, suggesting that fossil mammal faunas are useful also for inferring paleoenvironments (e.g. Andrews et al., 1979; Janis, 1984; Legendre, 1986; Kay and Madden, 1997a,b; MacFadden”
Why is the Land Green and the Ocean Red (2004, background): “The rapid co-evolution of grazing ungulates accompanied the expansion of grasses at this time, displacing browsers (Janis et al. 2002).”
Precipitation and large herbivorous mammals II: application to fossil data (2010, background): “Janis et al. (2002) presented data to show how the tooth crown height index (the hypsodonty index, HI) varies with both diet and habitat in 125 species of living ungulates of known dietary preference.”
The origins and diversification of C4 grasses and savanna‐adapted ungulates (2009, background): “The shifts from low- to high-crowned teeth in ungulates are likely to be related with shifts in their diet toward more fibrous vegetation (Jernvall et al., 1996) and shifts from browsing to grazing (Janis et al., 2002).”
Notoungulata and Litopterna of the Early Miocene Chucal Fauna, Northern Chile (2011, background): “In modern mammals, hypsodonty is highly correlated with dietary preference and can be used to distinguish animals feeding on vegetation in open habitats (which have more hypsodont teeth) from those feeding in closed habitats (Janis, 1988, 1995; Williams & Kay, 2001; Janis et al., 2002).”
Biodiversity in temperate European grasslands: origin and conservation. (2005, unknown): “Likewise among ungulates, the grassland-dwelling bulk-grazer habit evolved later from an ancestral forest-dwelling browsing habit (Pérez-Barbería et al. , 2001; Janis et al. , 2002).”
The species richness of Miocene browsers, and implications for habitat type and primary productivity in the North American grassland biome (2004, background): “We concluded (Janis et al., 2002) that these community similarities reflected the fact that environmental conditions in the later Miocene of North America had come to resemble the conditions of today’s world.”
An Evolutionary History of Browsing and Grazing Ungulates (2008, background): “The obvious interpretation of this correlation is that grit and dust accumulating on the food must also contribute to the abrasive nature of the diet (see Janis 1988; Janis et al. 2002 ).”
Grit not grass: Concordant patterns of early origin of hypsodonty in Great Plains ungulates and Glires (2012, background): “The hypsodont ungulates of the Oligocene show no cranial adaptations associated with predominantly grazing behaviour, such as broader muzzles.”
Fossil Record of Miocene Hominoids (2013, background): “…monsoons, desertification in North Africa, the early phases of Neogene polar ice cap expansion, and the expansion of North American grasslands (Garcés et al. 1997; Hoorn et al. 2000; Zhisheng et al. 2001; Griffin 2002; Guo et al. 2002; Janis et al. 2002; Liu and Yin 2002; Wilson et al. 2002).”
The latitudinal gradient of beta diversity in relation to climate and topography for mammals in North America (2009, unknown): “…species level, but we illustrate beta diversity at the genus and family levels for comparison with other studies of extant mammals (e.g. Kaufman, 1995) and with patterns in the fossil record that are often analysed at higher taxonomic levels (e.g. Janis et al ., 2002; Jernvall & Fortelius, 2002).”
