  • mutualisms;
  • elementary interactions between species - positive interactions, commensalisms and beneficial associations;

  • population trajectories, mutualistic species pair – facultative or obligate;
  • mutualisms, pollination and seed dispersal - plant gamete transport by animals;
  • plant–pollinator interactions, not as highly species-specific - as Yucca–Tegeticula system;
  • energetic and nutritional mutualisms - associations, organisms in different phyla;
  • associational defenses, frequency - neighborhood habitat amelioration, lower with stress levels;
  • obligate mutualisms, and constraints - ways, species colonize communities
