Which factors (limited space or overcrowding; limited food; Predators; parasite and diseased) tend to act in a density-dependent manner; Tony Sinclair (1989) many studies of density dependence in 51 populations of insects, 82 populations of large mammals, and 36 populations of small mammals and birds. Which of the following observation is most likely true?
a) Insects showed a wide variety of causes of density dependence and no one density-dependent factor was of overriding importance
b) The lesser the amount of available food, the greater the mortality of large mammals
c) Space and social interactions were more important for smaller mammals and birds, because they are more territorial
