Integrative Taxonomy of the Southernmost Tucu-Tucus in the World: Differentiation of the Nominal Forms Associated with Ctenomys
Mammalian Biology https://doi.org/10.1007/s42991-020-00015-z ORIGINAL ARTICLE Integrative taxonomy of the southernmost tucu‑tucus in the world: diferentiation of the nominal forms associated with Ctenomys magellanicus Bennett, 1836 (Rodentia, Hystricomorpha, Ctenomyidae) Pablo Teta1 · Guillermo D’Elía2 · Juan C. Opazo2 Received: 19 July 2019 / Accepted: 23 January 2020 © Deutsche Gesellschaft für Säugetierkunde 2020 Abstract We reviewed the alpha taxonomy of the genus Ctenomys Blainville, 1826 in southernmost South America, with emphasis on those nominal forms previously associated with C. magellanicus Bennett, 1836. We integrate distinct lines of evidence, including variation of mtDNA sequences, and the assessment of quantitative and qualitative traits of skins and skulls; when available, karyotypic data was also considered. Phylogenetic analysis of molecular markers shows low levels of divergence among specimens from southern South American mainland and the island of Tierra del Fuego (ca. 0.4%). This evidence plus the results of the multivariate analysis of metric data suggest that the nominal forms C. colburni J. A. Allen, 1903, C. fueginus Philippi, 1880, C. osgoodi J. A. Allen, 1905, C. m. dicki Osgood, 1943, and C. m. obscurus Texera, 1975 are subjective junior synonyms of C. magellanicus. In addition, we reviewed the status of C. fodax Thomas, 1910, a nominal form that have been alternatively considered as a valid species or related to C. magellanicus by previous researchers. Based on quantitative and qualitative morphological traits, we preliminarily regard C. fodax at the species level while citing it for the frst time to Chile.

Mammal Prey of the Barn Owl (Tyto Alba) in Parque Luro Reserve, La Pampa, Argentina

ABSTRACT - The diet of the barn owl was studied through the analysis of pcllets obtained in various sitcs within the Parque Luro reserve, located in an area of xerophyte CaldCn forests. The study of 1241 prcy items revealed a high dominance of the cricetid rodents Calomys sp., Akodon molinae and Eligmodoritia typus, followed by other 8 species of rodents, one species of marsupial and undetermined birds and anuran amphibians. For comparing the dicts from a relatively undisturbed forested area (Parque Luro) and a deforested site, two subcollections of pellets were analyzed. Differences in FNB values and in the prevalence and composition of prcy assemblages were observed between these areas. Key words: Rodentia, owl pellets, Argcntina.

AMEGHINIANA (Rev. Asoc. Paleontol. Argent.) - 41 (4): 651-664. Buenos Aires, 30-12-2004 ISSN 0002-7014 Functional and phylogenetic assessment of the masticatory adaptations in Cingulata (Mammalia, Xenarthra) Sergio F. VIZCAÍNO1, Richard A. FARIÑA2, M. Susana BARGO1 and Gerardo DE IULIIS3 Abstract. Cingulata -armadillos, pampatheres and glyptodonts- are among the most representative of South American Cenozoic mammalian groups. Their dental anatomy is characterised by homodonty, hypselodonty, and the absence of enamel in almost all known species. It has been proposed that these peculiarities are related to a primitive adaptation to insectivory and that they represent a strong phylogenetic constraint that restricted, or at least conditioned, adaptations toward other ali- mentary habits. However, the great diversity of forms recorded suggests a number of adaptive possibilities that range from specialised myrmecophagous species to carrion-eaters or predators among the animalivorous, and from selective browsers to bulk grazers among herbivores, as well as omnivores. Whereas armadillos (Dasypodidae) developed varied habits, mostly an- imalivorous but also including omnivores and herbivores, pampatheres (Pampatheriidae) and glyptodonts (Glyptodontidae) were herbivores. Morphofunctional and biomechanical studies have permitted a review of previous hypotheses based solely on comparative morphology. While in some cases these were refuted (carnivory in peltephiline armadillos), they were corrob- orated (carnivory in armadillos of the genus Macroeuphractus; -
Late Cenozoic Large Mammal and Tortoise Extinction in South America
Cione et al: Late Cenozoic extinction Rev.in South Mus. America Argentino Cienc. Nat., n.s.1 5(1): 000, 2003 Buenos Aires. ISSN 1514-5158 The Broken Zig-Zag: Late Cenozoic large mammal and tortoise extinction in South America Alberto L. CIONE1, Eduardo P. TONNI1, 2 & Leopoldo SOIBELZON1 1Departamento Científico Paleontología de Vertebrados, 'acultad de Ciencias Naturales y Museo, Paseo del Bosque, 1900 La Plata, Argentina. 2Laboratorio de Tritio y Radiocarbono, LATYR. 'acultad de Ciencias Naturales y Museo, Paseo del Bosque, 1900 La Plata, Argentina. E-mail: [email protected], [email protected], [email protected]. Corresponding author: Alberto L. CIONE Abstract: During the latest Pleistocene-earliest Holocene, South American terrestrial vertebrate faunas suffered one of the largest (and probably the youngest) extinction in the world for this lapse. Megamammals, most of the large mammals and a giant terrestrial tortoise became extinct in the continent, and several complete ecological guilds and their predators disappeared. This mammal extinction had been attributed mainly to overkill, climatic change or a combination of both. We agree with the idea that human overhunting was the main cause of the extinction in South America. However, according to our interpretation, the slaughtering of mammals was accom- plished in a particular climatic, ecological and biogeographical frame. During most of the middle and late Pleis- tocene, dry and cold climate and open areas predominated in South America. Nearly all of those megamammals and large mammals that became extinct were adapted to this kind of environments. The periodic, though rela- tively short, interglacial increases in temperature and humidity may have provoked the dramatic shrinking of open areas and extreme reduction of the biomass (albeit not in diversity) of mammals adapted to open habitats. -

E-mail: [email protected] Abstract: A new record of Euneomys chinchilloides (Waterhouse, 1839) at Parque Provincial Aconcagua (Mendoza, Argentina), is reported based on two fresh specimens found dead and several cranial remains found in owl pellet samples. The current record enlarges its distribution in the Andean region of Argentina ca. 250 km to the north. Euneomys chinchilloides (Waterhouse, 1839) is a large (mean weight of adults specimens = 85 g), short- tailed, cursorial sigmodontine rodent that lives in bare, windswept, rocky scree habitat along the southern Andes and the Patagonian steppes from about 35° S in Argentina and 33° S in Chile south to the Cabo de Hornos (Pearson 1995). In Argentina, its northernmost locality record corresponds to Laguna de la Niña Encantada (ca. -
Limb Reconstruction of Eutatus Seguini (Mammalia

Paleobiological implications Sergio F. VIZCAÍNO1, Nick MILNE2and M. Susana BARGO1 Abstract.Eutatus seguiniGervais is one of the largest members of the family Dasypodidae. It was very common during the Late Pliocene-Early Holocene in Uruguay and central-eastern Argentina. Some speci- mens that include well preserved and complete endoskeletal elements allowed to perform morpho-func- tional and biomechanical studies in order to infer locomotory adaptations. Comparative anatomical de- scriptions of Eutatus seguiniGervais with the recent armadillos Chaetophractus villosus(Desmarest), Dasypus hybridus(Desmarest), and the only living species of similar size Priodontes maximus(Kerr), were made. Its body mass was estimated through allometric equations. Different indices were calculated in or- der to analyse its limb proportions and their correlation with digging habits. The indices were compared with the values recorded for all living armadillo tribes, from mostly cursorial through subterranean. The general architecture and proportions of the limbs of E. seguini, and therefore its digging habits, are similar to those of the Euphractini and Dasypodini. Eutatus seguinishows unique features, for it reaches the size of the hiperspecialised digger and mirmecophagous Priodontes maximus, but with less fossorial specialisa- tion and markedly herbivorous feeding habits.
