We studied the temporal and spatial patterns in deforestation and community structure of mammals in a fragmented old-growth, temperate rain forest to test the hypothesis that anthropogenic habitat conversion advances in a nonrandom manner across native landscapes, and that its effects on ecological communities are both persistent and predictable. The location is the Hood Canal district of Olympic National Forest, Washington, USA. Deforestation followed the apparently general pattern observed for deforestation of tropical rain forests and other native landscapes, advancing first along low and relatively level valleys, then to areas at higher elevations and along steeper slopes, and eventually to sites more distant from those of initial land conversion and transportation centres. Mammal surveys within this area indicated that this nonrandom advance of deforestation has created relatively steep geographical and topographic gradients in both local and landscape-level factors and, ultimately, in the structure of mammalian communities. The close and likely causal relationship between anthropogenic habitat loss and the ecological dynamics of mammalian communities and dependent species (e.g. spotted owls) indicates that our abilities to understand and eventually reduce the current extinction crisis may rely heavily on our understanding of, and abilities to modify, the manner in which we expand across and transform native landscapes.

Background: Few methodologically rigorous international comparisons of student-reported antisocial behavior have been conducted. This paper examines whether there are differences in the frequency of both antisocial behavior and societal responses to antisocial behavior in Victoria, Australia and Washington State, United States. These 2 states were chosen due to their similarities on sociodemographic characteristics and their differences in policy frameworks around problem behavior including antisocial behavior and substance use. Methods: State representative samples of students (N = 5769) in school grades 5, 7, and 9 in Victoria and Washington State completed a modified version of the Communities That Care self-report survey of behavior and societal responses to behavior. Chi-square analyses compared frequencies of antisocial behavior, school suspensions, and police arrests in the 2 states. Multivariate logistic regression analyses were conducted for each outcome measure to examine the effect of state, controlling for sample design, clustering of students within schools, age, socioeconomic status, and urbanicity. Results: Few state differences in student-reported antisocial behavior were found, although frequencies varied across behavior type and grade level. Differences in societal responses were observed across grade levels with grade 5 Washington students reporting higher rates of school suspension. Older Washington students reported more arrests. Conclusions: Rates of student antisocial behavior appear similar in these 2 states in Australia and the United States. However, youth in the United States relative to Australia may experience greater societal consequences for problem behavior. Further research is required to examine the impact of these consequences on subsequent behavior. [ABSTRACT FROM AUTHOR]

The debate over the "community question" has generated several perspectives on the sources of ties to the territorial community in modern society. This paper attempts to empirically assess the utility of each model for predicting the number of ties to the local community and extra-local area, using data on voluntary association memberships in Seattle. Results indicate that the "community of limited liability" perspective is most accurate in predicting the importance of social, economic, and temporal investments for local memberships, and social position for extra-local memberships.'
