Abstract: This paper presents characteristics of droughts simulated by global climate models (GCMs) under enhanced greenhouse gases conditions. We used a drought index called the Reconnaissance Drought Index (RDI) which takes both rainfall and potential evapotranspiration into account to investigate variations of droughts among 12 regions in Australia. The RDI was applied to simulated climate variables from 14 GCMs performed for the IPCC 4th Assessment Report. The results show a general increase in drought areal extent and/or frequency for most regions. However, the increases are not significant over the North West, North Queensland, Queensland East Coast and Central Queensland. For most regions, the change beyond 2030 is larger than that prior to 2030, but the uncertainty in the projections also increases with time. By 2030, there is a likely (>66% probability) risk of twice or more drought affected area and/or twice as often drought frequency over South West Western Australia. By 2050, this will include the Murray-Darling Basin, South Australia and Victoria, and by 2070 this will extend to New South Wales and Tasmania. For North Queensland such a risk is unlikely (<33% probability) for the next 100 years. This information can be considered indicative in long-term planning focussing on sustainability.

This paper contains a description of a new species of oribatid mite, Birobates hepaticolus sp. nov., from eucalypt woodland and rainforest in North Queensland, Australia. Adults and immatures of B. hepaticolus live completely enclosed within the ventral lobules of the corticolous liverwort Frullania ferdinandi-muelleri Steph. The ventral lobes provide a protected, moisture-buffered microhabitat on tree bark that would otherwise be subject to extremes of wetting and drying. Analysis of gut contents indicates that B. hepaticolus appears to feed on liverwort tissue. To our knowledge this is the first documented example of an association between an oribatid mite and a leafy liverwort based on the provision of food and habitat. The genus Birobates is redefined and diagnosed. [ABSTRACT FROM AUTHOR]

The article discusses the coastal development of North Queensland. It states that the coastal development in the country has been started on the Gold Coast wherein developers and entrepreneurs recognized two potential markets such as homeowners and holiday makers. It states that the Sunshine Coast was developed following Gold Coast in which developers and business operators moved in to cater for tourists.

This article reflects upon collaborative research relationships between indigenous communities and universities in social health and empowerment programmes. This article is focused on Family Well Being programme and Indigenous Men's Support Groups conducted over the last decade at Yarrabah in northern Queensland. These programmes have incorporated a process whereby the community has set research agendas, local researchers have been employed, and university researchers have facilitated the development of appropriate programmes, the capacity of the community to manage these, and programme evaluation. This article draws upon reflective data derived from intensive group workshops and semistructured, in-depth interviews with both community and university-based researchers conducted in late 2006 and early 2007. These workshops and interviews describe, often in the words of participants, the experiences, challenges and strategies for research collaborations. This article recommends positive strategies for successful partnerships and outlines some challenges faced by both community and university researchers in programmes. The findings of the interviews and workshops are thematically discussed in relation to international literature on collaborative research. [ABSTRACT FROM AUTHOR]

Australian Nymphulinae are a diverse group of moths with aquatic caterpillars that probably play an important role in determining the composition and abundance of aquatic macrophytes in Australian freshwater systems. Less than 10% of the nymphuline larvae in Australia have been described. As part of a project to develop biological control agents for hydrilla, Hydrilla verticillata, we encountered a variety of Nymphulinae larvae feeding on this and other aquatic plants. We illustrate, describe and provide a key to five species of Nymphulinae larvae ( Ambia ptolycusalis (Walker), Parapoynx diminutalis Snellen, Hygraula nitens Butler, Margarosticha repititalis (Warren) and Theila siennata (Warren)) that feed on hydrilla in North Queensland. Information on their host plants also is included. Our field research indicates that none of these species should be considered as potential biological control agents for hydrilla.
