Adaptation to human-induced climate change is currently receiving a lot of attention in international development circles. But throughout human existence, natural resource-dependent people have exploited and coped with the effects of climate variability on the ecosystems from which they derive a...

European and American populations of the parasitoid Cotesia glomerata show pronounced differences in foraging behavior across plants and leaves. This variation in spatial aspects of foraging behavior was observed about 350 generations after the introduction of C. glomerata from Europe to North...

By their direct effects on private profitability, invasive agricultural pests create special incentives for management that set them apart from other categories of invasive species. One attractive nonchemical management approach for agricultural pests relies upon biological control by natural...

In heavily cleared agricultural landscapes, decline of biodiversity could be prevented by restoring native habitat. In this paper, we develop a spatially explicit bioeconomic model that optimizes ecological restoration of habitat for woodland-dependent birds in the Australian state of Victoria....

Optimal integrated control strategies for the weed blackberry (Rubus anglocandicans) infesting sheep pastures in Australia are analysed for a range of different circumstances. A wide range of control strategies with moderate to high costs and efficacies are analysed, including chemicals, mowing,...

Choosing the appropriate reservoir water management strategy can be difficult when the water has multiple uses. This study examines this problem for reservoir managers where water use involves irrigation and fisheries. A stochastic dynamic programming (SDP) model is developed to facilitate...
