This qualitative study examines sixteen women's understanding of their experiences in community organizing in a northern urban context. While most front-line community organizing is done by women, there is a paucity of research giving voice to their particular realities. Similarly, there is little information describing community organizing in a northern urban context. The study's conceptual frameworks draw on theory and research from rural and northern social work, activist mothering, feminist social policy, diversity and exclusion, and the social construction of identities. It follows a feminist research paradigm. The study illustrates women community organizers' sense of place and their perceptions of the politics of language, cultural and linguistic tensions, and the influences of northern economic and geographic realities. The research findings demonstrate the processes of community organizing in a northern setting, community organizers' demoralization because of increasingly less generous social policy environments, and the challenges of racial and linguistic divisions in community organizing. The study challenges the urban lens dominating social work education and highlights the legitimacy of community organizing within social work education. It discusses future research possibilities for cross-cultural community organizing involving minority francophone and ethnocultural populations as well as the relativity of notions of oppression within francophone spheres.

Metal-contamination of lakes simplifies food webs and reduces the efficiency of energy transfer to top trophic organisms, such as yellow perch (Perca flavescens). Benthic invertebrate community composition and yellow perch diet, growth and activity levels from lakes along a metal-contamination gradient were used to assess the importance of a naturally diverse prey base for maintaining energy transfer to growing fish, and how this is disrupted by metal-contamination. As perch grow larger, they shift their diet to larger prey; otherwise, the activity costs of foraging for many, small prey, instead of a few large prey, become too high and the fish stop growing. Metal contaminated lakes have less diverse zoobenthic communities, particularly the lack of large bodied invertebrate taxa, forcing perch to rely on smaller benthic prey. Perch from metal-contaminated lakes display slow growth and poor condition during benthivory. Estimates of fish activity, using the activity of the glycolytic enzyme Lactate dehydrogenase in perch white muscle tissue as a proxy, suggest that diet shifts to larger prey lower activity costs and may explain how diet shifts maintain growth efficiency as perch grow larger. Perch from metal-contaminated lakes cannot benefit from the energetic advantages of switching to larger prey and thus exhibit poor growth.
