Effect of aggregation on the reproductive rate of populations

  • Kohji Yamamura
Article

Summary

The effect of spatial distribution on the reproductive rate of a population was examined by applying an approximate equation to several data based on the entomological literature. This study suggests that aggregation generally reduces the equilibrium level of the population density if the population density is not very high.
