In this study, the possible causal links between the built environment, travel attitudes and travel behaviour of people that have moved between totally different urban and transportation contexts were investigated. A quasi-longitudinal design was developed to collect data about the perceived neighbourhood characteristics, neighbourhood preferences, travel attitudes and changes in car, walking a...

In this paper, we propose and analyze the design notion of dual-region mobility management (DrMoM) for achieving scalable, efficient location management of mobile nodes in ad hoc networks. The basic idea is to employ local regions to complement existing home region based location service schemes that assign a home region through hashing to a mobile node and have mobile nodes in both the home an...

—Within a species, home-range size can vary due to factors such as sex, mass, age, and breeding condition of individuals as well as habitat type, food availability, population density, and season. The objectives of this study were to estimate home ranges of deer mice (Peromyscus maniculatus) in sage-steppe habitat and to test the hypothesis that several factors (sex, mass, reproductive status, ...

Interactions between animal behaviour and the environment are both shaping observed habitat use. Despite the importance of inter-specific interactions on the habitat use performed by individuals, most previous analyses have focused on case studies of single species. By focusing on two sympatric populations of large herbivores with contrasting body size, we went one step beyond by studying varia...

Studies of basal metabolic rate (BMR), the minimum metabolic rate of postabsorptive, inactive endotherms while in their rest phase and thermal neutral zone, have contributed significantly to our understanding of animal energetics. Besides body mass, the main determinant of BMR, researchers have invoked diet and phylogenetic history as important factors that influence BMR, although their relativ...

The effects of increased mortality on the spatial dynamics of solitary carnivores are not well understood. We examined the spatial ecology of two cougar populations that differed in hunting intensity to test whether increased mortality affected home range size and overlap. The stability hypothesis predicts that home range size and overlap will be similar for both sexes among the two areas. The ...

OBJECTIVES Older adults with care needs live in a variety of settings-from traditional community housing to nursing homes. This analysis provides new estimates of the size and characteristics of the older population across settings and examines unmet needs for assistance. METHOD Data are from the 2011 National Health and Aging Trends Study (N = 8,077). Multinomial logistic regressions focus o...
