Abstract

IN the present discussions on factors limiting the size of natural populations1, investigations in helminthology, though they have much to contribute, have received little attention. A rigorously tested case of mutual habitat exclusion, as has been called for2, was demonstrated experimentally with Hymenolepis (Cestoda) and Moniliformis (Acanthocephala) in white rats3. More common than such cases of direct competition are examples of niche diversification among two to three congeneric species that may be found in the same host individual4–7. Co-existence of numerous related nematode species in vertebrates has also been claimed8.
