Abstract
Recent developments in ecological theory pertaining to the coexistence of insect species in response to forest disturbance are reviewed, and the findings are applied to the requirements for the Biological Survey of the Insects of Canada. It is important that a data collection system have a sound theoretical base, otherwise it will probably be found inadequate for the purpose for which it was designed. Questions about changes in faunal assemblages should be related to the scale of disturbance relative to the replacement time of the forest. Recommendations for research on faunal assemblage disturbance relationships are made for the Forest Insect and Disease Survey of Canada, and for the northern boreal forest.
