متن کاملBiological invasion and biological control select for different life histories
Biological invaders have long been hypothesized to exhibit the fast end of the life-history spectrum, with early reproduction and a short lifespan. Here, we examine the rapid evolution of life history within the harlequin ladybird Harmonia axyridis. The species, once used as a biological control agent, is now a worldwide invader. We show that biocontrol populations have evolved a classic fast l...
متن کاملBiological control and refuge theory.
REFERENCES tions arising from the intluences of host and parasitoid phenologies (3). Single values cannot characterize host-parasitoid interactions, and maximum values are unlikely to be typical over longer times or in different areas (4). 4) Contrary to the prediction made by Hawkins et al., successful biological control can result from the use of agents that are characterized by low rates of ...

متن کاملOn Prevention and Control of an Uncertain Biological Invasion
This paper examines how optimal prevention and control policies depend on the economic and biological characteristics of a randomly introduced biological invasion where the objective is to minimize the expected social costs from prevention, control, and invasion damages. The results characterize how optimal prevention and control policies vary with the initial invasion size, the invasion growth...
