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...

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 ...

The aim of this study was to examine the effects of various biological factors such as body mass, trophic level, climate and geography on census area in terrestrial mammals. The effects of census area on the population density-body mass relationship were also examined. The geographic areas covered i...

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...
