Nematoda

Abstract

For details of a modern classification of the group, consult the ‘CIH Keys to the Nematode Parasites of Vertebrates’³. In R. temporaria, R. esculenta and R. pipiens, however, relatively few species of nematodes commonly occur, so that a simple key based largely on location rather than morphology, generally suffices for identification. The key below deals with the commonest forms only; less common species are listed in Table 5.1 which also lists the classification. Comprehensive surveys of adult^{119, 177} and larval¹⁷⁹ nematodes in R. temporaria and R. esculenta are available. The nematodes found in R. pipiens have been reviewed by Walton^183–186.
