A central theme of the invasion biology literature is to predict the introduction and spread of biological invasions but predictive models rarely are applied to inform invasion management. Here, we demonstrate the utility of a spatio-temporal predictive model that has been used to inform...

Invasive species eradication programs can fail by applying management strategies that are not robust to potentially large but non-quantified risks. A more robust strategy can succeed over a larger range of possible values for non-quantified risk. This form of robustness analysis is often not...

An optimising model is developed to determine the .sequence of total allowable catches of western mackerel which would result in the maximum present value of the stream of annual rents. It is found that the optimal steady state fishing mortality would be one half to one third of recent levels....

Abstract It is pervasively argued that the equilibrium outcome for an open-access fishery in which harvesting cost is inversely related to fish stock is inefficient, with complete dissipation of within-season rents. However, some argue instead that within-season rents are maximised. Conditions...

Recent increases in the harvests of southern bluefin tuna, particularly by Australian fishermen, have led to the recognition that the fishery is overexploited. A model is developed to examine the effects that quotas on Australian and Japanese harvesting would have on economic welfare and on...
