Walker's mammals of the world

  title={Walker's mammals of the world},
  author={Ronald M. Nowak and Ernest P. Walker},
From aardwolves and bandicoots to yapoks and zorillas, Ernest P. Walker's Mammals of the World is the most comprehensive-the pre-eminent-reference work on mammals. Now, completely revised and updated, this fascinating guide is better than ever. Providing a complete account of every genus of mammal in all historical time, the sixth edition is 25 percent longer than its predecessor. Of the previous generic accounts, 95 percent have been substantively modified, and there are 80 new ones-among them… 

Taxonomy, Morphology, and Genetics of Wolves in the Great Lakes Region

Wolves are animals of the Class Mammalia, Order Carnivora, and Family Canidae that have a narrower body, a tail that does not curl, relatively larger teeth, and a flatter forehead and are in danger of extinction.

Why are there so many giants, including giant squirrels, in the Old World tropics?

Palaeo-community ecology must become an important research focus in body size evolution and be brought to bear on present ecology, to explain why vertebrates, including squirrels, are giants in the Old World compared to the New.

Monitors , Mammals , and Wallace ’ s Line

Although varanid lizards have achieved parity with mammals in many parts of the world, they exploit very different metabolic strategies and sensory mechanisms, and are properly regarded as convergent

Life History Patterns and the Comparative Social Ecology of Carnivores

This work will primarily review field studies focusing on the variation in behavior, body size, and life histories and emphasize data collected on identified individuals that have been observed directly (sometimes supplemented by radio-tracking) over long periods of time.


The potoroos differ from bettongs in their preference for more humid regions, whereas Aepyprymnus, although favoring similar habitat , has a greater mass than the betton gs.

Two decades of interaction between the MacArthur‐Wilson model and the complexities of mammalian distributions

Analysis of insular distributions show unequivocally that probabilities of extinction, colonization and speciation are highly deterministic and vary in predictable ways among different taxa and archipelagos, which have important implications for applying the theory and data ofinsular biogeography to the pressing practical problems of designing natural reserves to preserve native species.

Large Mesozoic mammals fed on young dinosaurs

A new species of triconodont mammal is reported, represented by a skeleton with most of the skull and postcranium preserved in articulation and stomach contents associated with a skeleton of R. robustus reveal remains of a juvenile Psittacosaurus, a ceratopsian dinosaur.

A new, diminutive species of Catopsalis (Mammalia, Multituberculata, Taeniolabidoidea) from the early Paleocene of southwestern Alberta, Canada

A new species of Catopsalis from the early Paleocene of Alberta is reported, which is not only the smallest species ofCatopsalis, but is the smallest taeniolabidoid so far discovered, with an estimated body mass between 400 g and 660 g.

Large Mesozoic mammals fed on young dinosaurs

Mesozoic mammals are commonly portrayed as shrewor ratsized animals that were mainly insectivorous, probably nocturnal and lived in the shadow of dinosaurs. The largest known Mesozoic mammal

Fathoming tropical biodiversity: the continuing discovery of Neotropical mammals

By analysing nomenclature for Neotropical mammals, two well-defined biases are documented that are associated with species accumulation: definite trends in body size are evident, so that larger organisms were more quickly apparent to systematists.
