Habitat selection by an arboreal lizard in an urban parkland: not just any tree will do

The nocturnal, arboreal Marbled Gecko, Christinus marmoratus, is a common reptile in urban areas in southern Australia. This study compared the demographics and the distribution of geckos occupying different tree species in a modified urban park, the Adelaide Parklands, with those of a population occurring in Ferguson Conservation Park, a nearby native vegetation remnant surrounded by suburbia. The geckos in the modified urban and native remnant parks demonstrated different demographic characteristics. These differences were explained by tree circumference and the amount and type of bark cover on the tree trunk. In the Parkland, geckos were limited by the availability of thick exfoliating bark, its clearly preferred microhabitat as demonstrated by a laboratory choice experiment. The preference for trees with larger circumference, more cover, and thick bark were probably linked to thermoregulation, predator avoidance, and food resources. This study supports the premise that to support populations of urban animals, tree species selection needs careful consideration with regard to its microhabitat capabilities as well as food provision and other resource supports it can provide.     

The Importance of Early Childhood Poverty

Most poor children achieve less, exhibit more problem behaviors and are less healthy than children reared in more affluent families. We look beyond correlations such as these to a recent set of studies that attempt to assess the causal impact of childhood poverty on adult well-being. We pay particular attention to the potentially harmful effects of poverty early in childhood on adult labor market success (as measured by earnings), but also show results for other outcomes, including out-of-wedlock childbearing, criminal arrests and health status. Evidence suggests that early poverty has substantial detrimental effects on adult earnings and work hours, but on neither general adult health nor such behavioral outcomes as out-of-wedlock childbearing and arrests. We discuss implications for indicators tracking child well-being as well as policies designed to promote the well-being of children.     

The Deployment of Partnerships by the Voluntary Sector to Address Service Needs in Rural and Small Town Canada

Service restructuring trends since the 1980s have resulted in the downsizing or closure of many services in rural and small town Canada. In response, voluntary groups have been filling some of the emerging service gaps. Services, however, often are directed at complex problems that demand information, support, or assistance from a range of sources and institutions. For voluntary groups, this underscores a need to partner with other groups, organizations, or service providers. At the same time, voluntary organizations are increasingly encouraged to develop partnerships with public or private partners in order to qualify for government funding. This study tracks 29 voluntary organizations in four rural and small town places across Canada to explore the development and maintenance of partnerships (both local and non-local), as well as the types of networks, resources, and expertise for which partnerships were used. The findings indicate that while voluntary organizations feel that local partnerships are more important, partnerships with groups outside of these places are equally developed. Partnerships were used to expand networks, obtain expertise, and access a range of resources to assist in daily operations and delivery of services. The increase in partnerships with groups outside of these communities, particularly with non-local service providers, will have important implications for voluntary organizations and policy makers.
