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. -

Samuels Keywords: Ursidae, Geometric morphometrics, Ursus americanus, Ursus arctos, Last Glacial Maximum ABSTRACT Cranial Morphological Distinctiveness Between Ursus arctos and U. americanus by Benjamin J. Hillesheim Despite being separated by millions of years of evolution, black bears (Ursus americanus) and brown bears (Ursus arctos) can be difficult to distinguish based on skeletal and dental material alone. Complicating matters, some Late Pleistocene U. americanus are significantly larger in size than their modern relatives, obscuring the identification of the two bears. -
Dental Anomalies in the Atlantic Population of South American Sea Lion, Otaria Byronia (Pinnipedia, Otariidae): Evolutionary Implications and Ecological Approach
e-ISSN 2236-1057 - doi:10.5597/lajam00044 http://dx.doi.org/10.5597/lajam00044 LAJAM 3(1): 7-18, January/June 2004 ISSN 1676-7497 DENTAL ANOMALIES IN THE ATLANTIC POPULATION OF SOUTH AMERICAN SEA LION, OTARIA BYRONIA (PINNIPEDIA, OTARIIDAE): EVOLUTIONARY IMPLICATIONS AND ECOLOGICAL APPROACH César Jaeger Drehmer 1, 2 , Marta Elena Fabián 2, 3 and João Oldair Menegheti 3 Abstract – We analyzed 63 cases of dental anomalies from 62 specimens of a total sample of 516 specimens of the Atlantic population of South American sea lions, Otaria byronia de Blainville, 1820. The anomalies were represented by 53 cases of missing upper post-canine 6 (second molars), seven cases of maxillary or mandibular extra teeth, two cases of “dentes geminati” and one case of reduced teeth. Considering a phylogenetic framework where all otariid species and basal Pinnipedimorpha are included, missing post-canine 6 could be related to evolutionary trends in Otariidae towards a progressive reduction and loss of teeth (agenesis). The occurrence of the upper post-canine 6 in Otaria Péron, 1816 as in Phocarctos Peters, 1866 is usually regarded as a primitive character. Alternatively, when adopting another cladistic procedure, this could be interpreted as a taxic atavism at the base of Otaria/Phocarctos clade. Extra-mandibular teeth are related to a concrete case of spontaneous atavism in the dentition of Otaria byronia, in retrogression to ancient groups like the Miocene pinnipediform Pteronarctos Barnes, 1989. The other anomalies – maxillary extra teeth, “dentes geminati” and reduced teeth - are caused by some disturbance on the epigenetic system underlying dental morphogenesis leading to duplication, coalescence or duplication and reduction of the dental germ, respectively. -
Quaternary Records of the Dire Wolf, Canis Dirus, in North and South America
Quaternary records of the dire wolf, Canis dirus, in North and South America ROBERT G. DUNDAS Dundas, R. G. 1999 (September): Quaternary records of the dire wolf, Canis dirus, in North and South Ameri- ca. Boreas, Vol. 28, pp. 375–385. Oslo. ISSN 0300-9483. 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.

La Brea and Beyond: the Paleontology of Asphalt-Preserved Biotas
La Brea and Beyond: The Paleontology of Asphalt-Preserved Biotas Edited by John M. Harris Natural History Museum of Los Angeles County Science Series 42 September 15, 2015 Cover Illustration: Pit 91 in 1915 An asphaltic bone mass in Pit 91 was discovered and exposed by the Los Angeles County Museum of History, Science and Art in the summer of 1915. The Los Angeles County Museum of Natural History resumed excavation at this site in 1969. Retrieval of the “microfossils” from the asphaltic matrix has yielded a wealth of insect, mollusk, and plant remains, more than doubling the number of species recovered by earlier excavations. Today, the current excavation site is 900 square feet in extent, yielding fossils that range in age from about 15,000 to about 42,000 radiocarbon years.

HOME RANGES and DIVING BEHAVIOR of NEW ZEALAND SEA LIONS ALONG the CATLINS COAST, SOUTH ISLAND, NEW ZEALAND a Dissertation by NA
HOME RANGES AND DIVING BEHAVIOR OF NEW ZEALAND SEA LIONS ALONG THE CATLINS COAST, SOUTH ISLAND, NEW ZEALAND A Dissertation by NATHAN MARK REED Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Randall Davis Committee Members, William Seitz Blair Sterba-Boatwright Bernd Würsig Intercollegiate Faculty Chair, Anja Schulze May 2021 Major Subject: Marine Biology Copyright 2021 Nathan Reed ABSTRACT New Zealand sea lions (Phocarctos hookeri) were extirpated from the North and South Islands of New Zealand during pre-European native hunting, and their numbers were greatly reduced on the Auckland and Campbell Islands during European commercial sealing. However, they began reoccupying South Island in 1994, and pup production remains low but steady. The home range, at-sea movements, and diving behavior of females at the breeding colony along the Catlins Coast of South Island have not been studied since its inception in 2006. The goal of the study was to: 1) evaluate the performance of home range models to identify the most accurate model(s) for a semi- aquatic distribution, 2) track movements to identify home ranges, and 3) record diving behavior of females to characterize foraging behavior and estimate energy expenditure. To accomplish this study, we attached satellite telemeters and video and data recorders to females along the Catlins Coast during austral winter of 2019. Home ranges were most accurately modeled by separating inshore and offshore habitats and applying adaptive local convex hulls (LOCOH) and fixed kernel density with plug-in bandwidth selection (PKDE), respectively. -
