Various plants and resources such as orchards are vulnerable to the detrimental effects of successful invasions by alien animal or plant species. To outline an appropriate policy response, we first use renewal theory to construct a stochastic model of optimal orchard management in the presence...

Biodiversity prospecting refers to the exploration of the commercial value of genetic and biochemical resources. In this chapter, we study a drug producing pharmaceutical firm (PF) that searches for potentially useful chemicals made by wild organisms in a conservation area. This PF is able to...

How should one manage the problem of resistance to antibiotics and pesticides? The formal modeling of this question is very much in its infancy. Therefore, we construct a dynamic and stochastic model of antibiotic or pesticide use to investigate the relative merits of two kinds of treatment...
