Interference and the ideal free distribution
Article Abstract:
The coefficient of interference, m, is used to quantify the intensity of competitive interference. Interference is the interaction between predators that reduces searching efficiency. The ideal free distribution is the ability by which the animals distribute themselves in an environment with different habitat quality. The ideal free distribution for different prey is obtained from the interaction of a group of predators. The value of m is very low not greater than 1, when interference results from wasted time. The proportion of animals in better patches is proportional to the food available.

The ideal free distribution with unequal competitors: the effects of modelling methods
Article Abstract:
Two techniques in distributing animals between habitats of differing quality are evaluated, with special emphasis on arrival sequence and the subsequent movements of animals between sites. In a random sequence of arrival among competitors, there is switching between patches among poor competitors, but when all the good competitors arrive before the good competitors, distribution follows the input matching rule. Undermatching is noted, wherein fewer animals use the habitat with the highest resource input rate than predicted by the input matching rule.

The distribution of animals between resources: a compromise between equal numbers and equal intake rates
Article Abstract:
A study of the distribution of animals between resources shows that switching of individuals exists at equilibrium, causing a distribution of animals. This distribution is a compromise between equal number of animals and equal intake rates at each resource. A simple continuous input model used in this study refutes the occurrence of equal intake rates at equilibrium, suggesting that the mutants spend more time on a better patch.
