An audit of local government planning tools for their potential use in addressing community food and nutrition issues

Issues addressed: This project aimed to identify how local government planning tools could be used to influence physical and policy environments to support healthy eating behaviours in communities.
Methods: An audit of Queensland's legislative and non-legislative local government planning tools was conducted by a public health nutritionist to assess their potential use in addressing strategies to achieve positive nutrition outcomes. Ten strategies were identified and covered the following themes: improving access to healthy foods and drinks; increasing access to breastfeeding facilities; decreasing fast food outlet density; and unhealthy food advertising. 
Results: The audit found that all of the 10 strategies to achieve positive nutrition outcomes could be considered through three or more of the planning tools.
Conclusion: Based on the findings of this audit, local government planning tools provide opportunities to address food and nutrition issues and contribute toward creating physical and policy environments that support healthy eating behaviours.

Examining potential barriers to early intervention access in Australian hearing impaired children

Early intervention for children with hearing loss involves assistance in oral speech development, optimal use of hearing devices and fostering a holistic partnership between allied health and the children's families. Adequate access to early intervention has been shown to be vital in the positive development of long term language and social outcomes. However, there has been limited research to identify the factors which may influence access. This study aimed to explore whether access to early intervention by children with hearing loss is affected by: geographical location, socio-economic status and ethnic-minority family status.

Genetic analyses reveal limited dispersal and recovery potential in the large freshwater crayfish Euastacus armatus from the southern Murray-Darling Basin

Understanding dispersal traits and adaptive potential is critically important when assessing the vulnerability of freshwater species in highly modified ecosystems. The present study investigates the population genetic structure of the Murray crayfish Euastacus armatus in the southern Murray–Darling Basin. This species has suffered significant population declines in sections of the Murray River in recent years, prompting the need for information on natural recruitment processes to help guide conservation. We assessed allele frequencies from 10 polymorphic microsatellite loci across 20 sites encompassing the majority of the species’ range. Low levels of gene flow were observed throughout hydrologically connected waterways, but significant spatial autocorrelation and low migration rate estimates reflect local genetic structuring and dispersal limitations, with home ranges limited to distances <50-km. Significant genetic differentiation of headwater populations upstream of barriers imposed by impoundments were also observed; however, population simulations demonstrate that these patterns likely reflect historical limitations to gene flow rather than contemporary anthropogenic impacts. Dispersal limitations, coupled with its biological traits, suggest that local populations are vulnerable to environmental disturbance with limited potential for natural recolonisation following population decline. We discuss the implications of these findings in the context of managing the recovery of the species.
