UNIVERSITY of CALIFORNIA Los Angeles Carnivory UNIVERSITY OF CALIFORNIA Los Angeles Carnivory in the Oligo-Miocene: Resource Specialization, Competition, and Coexistence Among North American Fossil Canids A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Biology by Mairin Francesca Aragones Balisi 2018 © Copyright by Mairin Francesca Aragones Balisi 2018 ABSTRACT OF THE DISSERTATION Carnivory in the Oligo-Miocene: Resource Specialization, Competition, and Coexistence Among North American Fossil Canids by Mairin Francesca Aragones Balisi Doctor of Philosophy in Biology University of California, Los Angeles 2018 Professor Blaire Van Valkenburgh, Chair Competition likely shaped the evolution of the mammalian family Canidae (dogs and their ancestors; order Carnivora). From their origin 40 million years ago (Ma), early canids lived alongside potential competitors that may have monopolized the large-carnivore niche—such as bears, bear-dogs, and nimravid saber-toothed cats—before becoming large and hypercarnivorous (diet of >70% meat) later in their history. This ecomorphological context, along with high phylogenetic resolution and an outstanding fossil record, makes North American fossil canids an ideal system for investigating how biotic interactions (e.g. competition) and ecological specialization (e.g. hypercarnivory) might influence clade evolution. Chapter 1 investigates whether ecological generalization enables species to have longer durations and broader geographic range. I developed and applied a carnivory index to 100+ ii species, processing 3708 occurrences through a new duration-estimation method accounting for varying fossil preservation. A non-linear relationship between duration and carnivory emerged: both hyper- and hypocarnivores have shorter durations than mesocarnivores. Chapter 2 tests the cost of hypercarnivory, quantified as elevated extinction risk. Large hypercarnivorous canids experienced extinction rates on par with other canids. However, in each canid subfamily, extinction rates rose after the first occurrence of large hypercarnivores, supporting the idea of hypercarnivory as a “macroevolutionary ratchet” for individual clades. Large hypercarnivores originated just over 10 Ma after the origin of Canidae, exhibiting constant diversification rates and peaking in richness around 12 Ma. Relationships emerge between diversification rates of canid subfamilies and temperature, suggesting future hypotheses to be investigated. Chapter 3 quantifies functional morphology in 114 fossil canids and non-canid competitors from 40 to 15 Ma, testing for ecological congruence between continental and regional scales and whether ecomorphological disparity reflects taxonomic diversity. Disparity appears inversely related to diversity. All four geographic regions examined preserved a narrower range of ecomorphology than at the continental scale. These results suggest that partitioning dietary as well as geographic resources, despite constraints to size, permitted canids to minimize competition and diversify. These macroecological and macroevolutionary studies of early canids and their potential competitors improve understanding of the resilience of the carnivore niche over long timescales, including periods of accelerated global change. iii The dissertation of Mairin Francesca Aragones Balisi is approved.

  • Mammalia, Felidae, Canidae, and Mustelidae) from the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas
    Chapter 9 Carnivora (Mammalia, Felidae, Canidae, and Mustelidae) From the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas MARGARET SKEELS STEVENS1 AND JAMES BOWIE STEVENS2 ABSTRACT The Screw Bean Local Fauna is the earliest Hemphillian fauna of the southwestern United States. The fossil remains occur in all parts of the informal Banta Shut-in formation, nowhere very fossiliferous. The formation is informally subdivided on the basis of stepwise ®ning and slowing deposition into Lower (least fossiliferous), Middle, and Red clay members, succeeded by the valley-®lling, Bench member (most fossiliferous). Identi®ed Carnivora include: cf. Pseudaelurus sp. and cf. Nimravides catocopis, medium and large extinct cats; Epicyon haydeni, large borophagine dog; Vulpes sp., small fox; cf. Eucyon sp., extinct primitive canine; Buisnictis chisoensis, n. sp., extinct skunk; and Martes sp., marten. B. chisoensis may be allied with Spilogale on the basis of mastoid specialization. Some of the Screw Bean taxa are late survivors of the Clarendonian Chronofauna, which extended through most or all of the early Hemphillian. The early early Hemphillian, late Miocene age attributed to the fauna is based on the Screw Bean assemblage postdating or- eodont and predating North American edentate occurrences, on lack of de®ning Hemphillian taxa, and on stage of evolution.

  • Mammalia: Carnivora) in the Americas: Past to Present
    Journal of Mammalian Evolution https://doi.org/10.1007/s10914-020-09496-8 ORIGINAL PAPER Environmental Drivers and Distribution Patterns of Carnivoran Assemblages (Mammalia: Carnivora) in the Americas: Past to Present Andrés Arias-Alzate1,2 & José F. González-Maya3 & Joaquín Arroyo-Cabrales4 & Rodrigo A. Medellín5 & Enrique Martínez-Meyer2 # Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Understanding species distributions and the variation of assemblage structure in time and space are fundamental goals of biogeography and ecology. Here, we use an ecological niche modeling and macroecological approach in order to assess whether constraints patterns in carnivoran richness and composition structures in replicated assemblages through time and space should reflect environmental filtering through ecological niche constraints from the Last Inter-glacial (LIG), Last Glacial Maximum (LGM) to the present (C) time. Our results suggest a diverse distribution of carnivoran co-occurrence patterns at the continental scale as a result of spatial climatic variation as an important driver constrained by the ecological niches of the species. This influence was an important factor restructuring assemblages (more directly on richness than composition patterns) not only at the continental level, but also from regional and local scales and this influence was geographically different throughout the space in the continent. These climatic restrictions and disruption of the niche during the environmental changes at the LIG-LGM-C transition show a considerable shift in assemblage richness and composition across the Americas, which suggests an environ- mental filtering mainly during the LGM, explaining between 30 and 75% of these variations through space and time, with more accentuated changes in North than South America.

  • Carnivore-Specific Stable Isotope Variables and Variation in The
    458 Carnivore-specific stable isotope variables and variation in the foraging ecology of modern and ancient wolf populations: case studies from Isle Royale, Minnesota, and La Brea K. Fox-Dobbs, J.K. Bump, R.O. Peterson, D.L. Fox, and P.L. Koch Abstract: We use carbon and nitrogen isotope data collected from two North American gray wolf (Canis lupus L., 1758) populations (Isle Royale and northern Minnesota) to both calculate carnivore-specific isotopic variables and investigate wolf foraging ecology. The isotopic enrichments of 13C and 15N that occur between mammalian carnivores and their prey have not been well defined in modern populations. We use bone collagen from the Isle Royale National Park wolf, moose (Alces alces (L., 1758)), and beaver (Castor canadensis Kuhl, 1820) populations to determine trophic enrichment factors of 1.3% ± 0.6% for d13C and 4.6% ± 0.7% for d15N. We apply these carnivore-specific fractionation factors to a case study from the fossil record, and reconstruct the diets of late-Pleistocene dire wolves (Canis dirus (Leidy, 1858)) from the La Brea tar pits. We use the Minnesota wolf tissue (collagen, hair, muscle) isotopic data to estimate carnivore population subsample sizes needed to replicate the mean values of the whole population within one standard deviation. Finally, we compare the Isle Royale and Minnesota collagen and hair isotopic data to published d13C and d15N values for North Amer- ican gray wolf populations. We find that interpopulation differences in isotope variances provide insight into wolf foraging ecology.

  • Paleoecological Comparison Between Late Miocene Localities of China and Greece Based on Hipparion Faunas
    Paleoecological comparison between late Miocene localities of China and Greece based on Hipparion faunas Tao DENG Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing 100044 (China) [email protected] Deng T. 2006. — Paleoecological comparison between late Miocene localities of China and Greece based on Hipparion faunas. Geodiversitas 28 (3) : 499-516. ABSTRACT Both China and Greece have abundant fossils of the late Miocene Hipparion fauna. Th e habitat of the Hipparion fauna in Greece was a sclerophyllous ever- green woodland. Th e Chinese late Miocene Hipparion fauna is represented respectively in the Guonigou fauna (MN 9), the Dashengou fauna (MN 10), and the Yangjiashan fauna (MN 11) from Linxia, Gansu, and the Baode fauna (MN 12) from Baode, Shanxi. According to the evidence from lithology, carbon isotopes, paleobotany, taxonomic framework, mammalian diversity and faunal similarity, the paleoenvironment of the Hipparion fauna in China was a subarid open steppe, which is diff erent from that of Greece. Th e red clay bearing the Hipparion fauna in China is windblown in origin, i.e. eolian deposits. Stable carbon isotopes from tooth enamel and paleosols indicate that C3 plants domi- nated the vegetation during the late Miocene in China. Pollens of xerophilous and sub-xerophilous grasses show a signal of steppe or dry grassland. Forest mammals, such as primates and chalicotheres, are absent or scarce, but grass- land mammals, such as horses and rhinoceroses, are abundant in the Chinese Hipparion fauna. Th e species richness of China and Greece exhibits a similar KEY WORDS trend with a clear increase from MN 9 to MN 12, but the two regions have Hipparion fauna, low similarities at the species level.

The dire wolf was an important large, late Pleistocene predator in North and South America, well adapted to preying on megaherbivores. Geographically widespread, Canis dirus is reported from 136 localities in North America from Alberta, Canada, southward and from three localities in South America (Muaco, Venezuela; Ta- lara, Peru; and Tarija, Bolivia). The species lived in a variety of environments, from forested mountains to open grasslands and plains ranging in elevation from sea level to 2255 m (7400 feet). Canis dirus is assigned to the Rancholabrean land mammal age of North America and the Lujanian land mammal age of South Amer- ica and was among the many large carnivores and megaherbivores that became extinct in North and South America near the end of the Pleistocene Epoch.
