There is a lack of information regarding the ecology and behaviour of red foxes that can be used to elaborate effective management programs for this species on Prince Edward Island (Canada). The main goal of this study was to provide baseline information on habitat selection and home range size of r...

We examined the influence of habitat characteristics at the microhabitat, macrohabitat, and landscape spatial scales on small mammals occurring in 12 forest patches within four agricultural landscapes of Prince Edward Island (Canada). Landscape features were important determinants of small mammal va...

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...

We surveyed 11 forest remnants and their adjacent ponds to assess the species richness of amphibians on Prince Edward Island, Canada. By combining aquatic and terrestrial sampling methods, we detected the presence of four urodeles and five anurans in our study sites. No significant difference in spe...

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...

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...

Anthropogenic activities in Prince Edward Island (Canada) have created a mosaic of fragmented uneven-aged forests and agricultural and pasture lands, as well as large amounts of edge habitat. Although the mammalian fauna of the province is largely composed of small mammals, no previous study has inv...

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),...

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...

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 ...

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...
