Title: On the complex formation approach in modeling predator
  prey relations, mating, and sexual disease transmission

Abstract: 
  Complex formation is used as a unified approach to
  derive representations and approximations of the functional
  response in predator prey relations, mating, and sexual disease
  transmission. Applications are given to the impact of a generalist
  predator on a prey population and the spread of a sexually
  transmitted disease in a multi-group heterosexual population.
