Interspecific and geographic variation in the diets of sympatric carnivores: dingoes/wild dogs and red foxes in south-eastern Australia

Dingoes/wild dogs (Canis dingo/familiaris) and red foxes (Vulpes vulpes) are widespread carnivores in southern Australia and are controlled to reduce predation on domestic livestock and native fauna. We used the occurrence of food items in 5875 dingo/wild dog scats and 11,569 fox scats to evaluate interspecific and geographic differences in the diets of these species within nine regions of Victoria, south-eastern Australia. The nine regions encompass a wide variety of ecosystems. Diet overlap between dingoes/wild dogs and foxes varied among regions, from low to near complete overlap. The diet of foxes was broader than dingoes/wild dogs in all but three regions, with the former usually containing more insects, reptiles and plant material. By contrast, dingoes/wild dogs more regularly consumed larger mammals, supporting the hypothesis that niche partitioning occurs on the basis of mammalian prey size. The key mammalian food items for dingoes/wild dogs across all regions were black wallaby (Wallabia bicolor), brushtail possum species (Trichosurus spp.), common wombat (Vombatus ursinus), sambar deer (Rusa unicolor), cattle (Bos taurus) and European rabbit (Oryctolagus cuniculus). The key mammalian food items for foxes across all regions were European rabbit, sheep (Ovis aries) and house mouse (Mus musculus). Foxes consumed 6.1 times the number of individuals of threatened Critical Weight Range native mammal species than did dingoes/wild dogs. The occurrence of intraguild predation was asymmetrical; dingoes/wild dogs consumed greater biomass of the smaller fox. The substantial geographic variation in diet indicates that dingoes/wild dogs and foxes alter their diet in accordance with changing food availability. We provide checklists of taxa recorded in the diets of dingoes/wild dogs and foxes as a resource for managers and researchers wishing to understand the potential impacts of policy and management decisions on dingoes/wild dogs, foxes and the food resources they interact with.

Duality theory and forms of organizing

This paper presents results from a survey of organizing forms in Australia's largest public companies between 2000 and 2004. The study sought to identify trends in forms of organizing and the extent to which the uptake of new forms led to a decrease in traditional forms of organizing. The analysis revealed changes across the organizational dimensions of structures, processes and boundaries. While Australian firms were clearly interested in exploring new forms of organizing, uptake was not universal, nor at the expense of traditional forms of organizing. An admixture of traditional and new, or dual, forms of organizing emerged as the preferred response to environmental turbulence. This paper employs and extends duality theory to explain the changes that occurred in Australian public companies over the four year period. Duality theory is operationalized in terms of five duality characteristics, which are employed to assess the composition and balance of traditional and new fOlms of organizing. The paper proposes that a dualities aware perspective offers a potential way forward in managing the balance between ostensibly contradictory forces of continuity and change.

Regrettable turnover

The purpose of this paper is to present a conceptual framework to identify antecedent variables that impact on the quit/stay decisions of high value workers. In this framework, the unfolding model of voluntary turnover is enhanced by consideration of job embeddedness, and affect-driven approaches. The concept of regrettable turnover is introduced to describe acute forms of dysfunction caused when key employees quit. The regret is experienced by managers, and heavily influenced by the criteria used to judge the value of such individuals. Therefore another key aim of this paper is to build on the literature of turnover functionality to propose a more detailed set of criteria reflecting the increasingly uncertain and dynamic environments in which organisations must operate.
