Biotic interactions — effects on man

  • J. R. Lloyd
Part of the Foundations of Biology book series (FOUNDBIO)


All the interactions listed in the table on page 22 affect man. Many interactions are beneficial, such as mutualism between nitrogen fixing bacteria and man’s leguminous crops. Those which cause diseases and crop losses are discussed in more detail here because they illustrate the application of ecological principles well and pose ecological problems for those who attempt to control them. It must be remembered that these are just two selected cases from the immense and complex web of interactions which involve man.
