Host Characteristics, Sampling Intensity, and Species Richness of Lepidoptera Larvae on Broad‐Leaved Tress in Southern Ontario
1983
Karban, Richard | Ricklefs, Robert E.
Lepidopteran species richness was strongly related to sampling intensity as measured by the number of collections made by the Canadian Forest Insect Survey of insects on broad—leaved trees in Ontario. Local abundance of the host, independently estimated by Beschel et al. (1962), and ecological and geographical distribution of the host were unrelated to the local species richness of Lepidoptera when the effect of sampling intensity was accounted for. The importance of collecting effort in this analysis of an extensive sampling program suggests that the effect of sample size must be considered before it is possible to test the effects of host characteristics on herbivore species richness.
