The increased demographic performance of biological invaders may often depend on their escape from specifically adapted enemies. Here we report that native taxa in colonized regions may swiftly evolve to exploit such emancipated exotic species because of selection caused by invaders. A native Australian true bug has expanded it host range to include a vine imported from tropical America that has become a serious environmental weed. Based on field comparisons and historical museum specimens, we show that over the past 30-40 years, seed feeding soapberry bugs have evolved 5-10% longer mouthparts, better suited to attack the forest-invading balloon vines, which have large fruits. Laboratory experiments show that these differences are genetically based, and result in a near-doubling of the rate at which seeds are attacked. Thus a native biota that initially permits invasion may rapidly respond in ways that ultimately facilitate control.

Objective: Alcohol contributes to about 30% of drowning fatalities associated with recreational aquatic activity and to 35% of drownings associated with boating. We consider regulatory and legislative strategies for preventing such deaths. Methods: We contacted water police in each Australian State and Territory to identify legislation creating alcohol-related offences for operators of recreational boats in their jurisdiction and to determine whether they conducted random breath testing (RBT). We also sought information from all 152 (81 urban and 71 rural) local government councils in NSW regarding restrictions on consumption of alcohol in public places within their shires. Results: Four Australian States (New South Wales, Queensland, Victoria and South Australia) have legislation prescribing maximum blood alcohol concentrations (BACs) for operators of recreational boats; all support this with RBT Western Australia, Tasmania and the Australian Capital Territory define more general offences for operating vessels while under the influence, of alcohol. Prohibitions or restrictions on consumption of alcohol in public places exist in 78 of the 86 shires in NSW that responded: 69 councils had alcohol-free zones, 53 restricted consumption of alcohol in public parks and reserves, and 33 had prohibitions or restrictions in some aquatic environments. Conclusions/implications: Legislation restricting BACs for recreational boat operators should be adopted in all Australian States and Territories. Optimal legislation would require that all occupants of recreational boats are required to comply with prescribed BAC levels, including when vessels are at anchor. Extension of by-laws prohibiting or restricting the consumption of alcohol specifically in aquatic environments warrants consideration.

Objective: The purpose of this study was to explore methods of determining an appropriate caseload for mental health case managers. Method: Seven factors that may impinge on case manager performance and impact on caseload were identified, having reference to published literature and service practice in Victoria and Queensland. The advantages and disadvantages of including these factors in a caseload index were evaluated. Results: Three caseload index methodologies are presented. Each method makes use of different data and has advantages and disadvantages. There is a trade-off between simplicity and ease of application and the comprehensive use of relevant information. Methods vary in their implications for service efficiency and equity in workload distribution. Conclusions: Caseload is a key issue in service planning and staff management. Factors that have the potential to contribute to caseload can be readily identified. However, there is likely to be disagreement as to the weight assigned to any factor and the approach taken may depend on the purpose and context of the caseload calculation. A great deal more research is required to provide an empirical basis for algorithms used in caseload calculation.

Full-length genome sequences of five virulent and five avirulent strains of Newcastle disease virus isolated between 1998 and 2002 in Victoria and New South Wales, Australia were determined. Comparisons between these strains revealed that coding sequence variability in the haemagglutinin-neuraminidase (HN), matrix (M) and phosphoprotein (P) gene sequences appeared to be more variable than in the fusion (F), nucleocapsid (N) and RNA dependent-RNA replicase (L) genes. Sequence analysis of a number of other isolates made during the recent virulent NDV outbreaks, also identified the presence of a number of variants with altered F gene cleavage sites, which resulted in altered biological properties of those viruses. Quasispecies analysis of a number of field isolates indicated the presence of virulent virus in one particular isolate. Gene sequence analysis of the progenitor virus isolated in 1998 showed very little sequence variation when compared to that of a progenitor-like virus isolated in 2001 demonstrating that in the field. viral genome sequence variation appears to be biologically restricted to that of a consensus sequence.
