Anuran responses to spatial patterns of agricultural landscapes in Argentina

Context: Amphibians are declining worldwide and land use change to agriculture is recognized as a leading cause. Argentina is undergoing an agriculturalization process with rapid changes in landscape structure. Objectives: We evaluated anuran response to landscape composition and configuration in two landscapes of east-central Argentina with different degrees of agriculturalization. We identified sensitive species and evaluated landscape influence on communities and individual species at two spatial scales. Methods: We compared anuran richness, frequency of occurrence, and activity between landscapes using call surveys data from 120 sampling points from 2007 to 2009. We evaluated anuran responses to landscape structure variables estimated within 250 and 500-m radius buffers using canonical correspondence analysis and multimodel inference from a set of candidate models. Results: Anuran richness was lower in the landscape with greater level of agriculturalization with reduced amount of forest cover and stream length. This pattern was driven by the lower occurrence and calling activity of seven out of the sixteen recorded species. Four species responded positively to the amount of forest cover and stream habitat. Three species responded positively to forest cohesion and negatively to rural housing. Two responded negatively to crop area and diversity of cover classes. Conclusions: Anurans within agricultural landscapes of east-central Argentina are responding to landscape structure. Responses varied depending on species and study scale. Life-history traits contribute to responses differences. Our study offers a better understanding of landscape effects on anurans and can be used for land management in other areas experiencing a similar agriculturalization process.Facultad de Ciencias ExactasCentro de Investigaciones del Medioambient

Planning primary health-care services for South Australian young offenders: A preliminary study

The definitive version of this article can be found at www.blackwell-synergy.comAlthough many young offenders receive health care during periods of detention, addressing their health needs after release from secure care is a key strategy for successful rehabilitation and reintegration into the community. The purpose of this preliminary study was to examine current discharge planning practices for young offenders in Youth Training Centres in South Australia with a view to improving offenders' connection with primary health-care services on discharge. To determine the strengths and weaknesses of current discharge planning practices, this exploratory study involved in-depth review of literature and a semistructured focus group of stakeholders. Findings were discussed with an expert advisory group before final recommendations were made. This study identified a service model approach to discharge planning that recommended a nurse located within the Divisions of General Practice as the coordinator. The study found that trusted staff in detention centres, with an awareness of services available in the location of release, influence young offenders' decision-making in relation to health-care services. Awareness and recognition of young offenders' health beyond periods of juvenile detention and into their adult lives is valuable in that it has the potential to establish lifelong healthy behaviours. Bonding with young offenders and gaining their trust increases their likelihood of attending primary health-care services
