Analyzes predictions made by previous allometric analyses of the relationship between population density and body mass. Ecological density of terrestrial mammal populations; Effect of trophic groups and body sizes of community members and the range of sizes; Energy use of herbivores, carnivores, and...

Little is known about the small mammalian fauna of Prince Edward Island (Canada), particularly shrews. Although historical data indicate the presence of five shrew species on Prince Edward Island (Sorex cinereus, S. fumeus, S. hoyi, S. palustris and Blarina brevicauda), recent studies have failed to...

Small mammal communities were studied in eight vegetation types of the Prince Edward Island National Park. Ten species were trapped. Shannon-Weiner index of diversity was high in Red Pine[Pinus resinosa] plantations (1.33 and 1.55) and a bog (1.47), and low for opened habitats such as a dune (0.19),...

Aim The aim of this study was to investigate the effects of climate, geography, census area and the distribution of body mass on the mass : density relationship in terrestrial mammal populations. Location The areas covered include most major terrestrial biomes including the tropics, savannas, and te...

1. Data from 364 mammal and 564 bird species were used to compare these two taxa in the patterns of variation in population density and energy use as a function of body mass. 2. This study demonstrates previously unappreciated quantitative differences between mammals and birds. Over a wide range of ...

Allometric scaling of body length was examined for 1,733 estimates of body length for a broad taxonomic and size range of mammals. Mammal species were classified by locomotion, habitat, and taxonomic relatedness. Scaling exponents found in different groups of mammals were compared to those predicted...

Two hypotheses have been suggested to explain the form of interspecific scaling of organismal characteristics to body size, such as the well-known increase in total metabolism with body mass. A hypothesis based on simple Euclidean geometry suggests that the scaling of many biological variables to bo...
