The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]
, 2019 The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Ecogeographical Variation in Skull Shape of South-American Canids: Abiotic or Biotic Processes? [PDF]
, 2015 Species morphological changes can be mutually influenced by environmental or biotic factors, such as competition. South American canids represent a quite recent radiation of taxa that evolved forms very disparate in phenotype, ecology and behaviour ...

Vulpes Ferrilata (Carnivora: Canidae) [PDF]
Mammalian Species, 2008 The canid Vulpes ferrilata Hodgson, 1842, is commonly called the Tibetan sand fox, or sand fox. It is widely distributed in the steppes and semideserts of the Tibetan Plateau north through central China. V. ferrilata has thick fur adapted for cold climate, and it occurs in semiarid to arid upland plains, on barren slopes and hills at elevations of 2 ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal
Wildlife Biology, EarlyView.Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

DNA proves the Warrah was a wolf : and got to the Falklands unaided [PDF]
, 2010 The Falkland Islands hit the headlines at the beginning of November 2009, and for a rather unusual reason. The DNA of the warrah, the extinct Falklands wolf, had been sequenced and the results published in the scientific journal Current Biology.

Revision sistematica de “canis” ensenadensis ameghino 1888 (carnivora, canidae) y la des- cripcion de un nuevo especimen del Pleistoceno de Argentina. [PDF]
, 2014 The fossil record of foxes in South America is very rich, with almost all extant South American species recorded. Currently, three fossil species are known in the Plio-Pleistocene of South America: "Dusicyon" cultridens, Dusicyon avus and "Canis ...

Zoo Biology, EarlyView.We distributed a survey to global institutions housing bush dogs (Speothos venaticus) to collect data on factors which may affect litter survival. Information from the Zoological Information Management System (ZIMS) and studbook records supplemented this dataset. We found that within northern temperate regions, the number of pups reared to the age of 1

Systematic Review of Prognostic Factors for Mortality in Dogs with Immune-mediated Hemolytic Anemia [PDF]
, 2015 BACKGROUND: Treatment of dogs with primary immune‐mediated hemolytic anemia (IMHA) is difficult and frequently unrewarding. Prognostic factors have been evaluated in a number of previous studies, and identification of such factors would be beneficial to ...
