Subinjurious Maintenance Strategies for Optimal Control of Nematodes,. We derive optimal long-term control strategies for this particularly simple case. The technique is applied to a model of the root-knot nematode . in resistant-susceptible crop mixtures. The results emphasise the importance of understanding the dynamics of root infection.

Estimating Controllability Boundaries for Uncertain Systems,set generally differs from the actual reachable set, but the estimate is conservative (i.e., guaranteed to contain the actual reachable set), does not require integration of the equations of motion, and is applicable to n-dimensional systems. Both methods are applied to an example of a prey-predator fishery with bounded harvesting efforts.

Estimating the Effect of Krill Harvesting on the Southern Ocean Ecosystem,ons of this problem are described in this paper in terms of simple empirical models. These models may be viewed as providing some empirical underpinning of the theoretical considerations of May et al. (1979).

Mathematical Models and Resource Management,The fact that resource management regimes are breaking down in almost all ecological applications dramatizes the need for a technology based on an adequate theory. Failures in pest control and fisheries bear grim witness to this need.
