Glossary of Terms and Concepts Useful in Ciliate Systematics
With the increasing contribution of data from other fields to the systematics of ciliates and the growing interest of biologists of all persuasions in these microorganisms, we ought today to be familiar with a far greater range of terms than was required in the past. The information offered below not only provides, in the aggregate, a “thumbnail sketch” of most aspects in the overall biology of ciliates, but also permits use of the terminology in succeeding chapters without the need to reexplain it there. Our treatment is not exhaustive—and many commonly known anatomical, cytological, and ecological words are purposely omitted—but this compilation is longer than those presented for ciliates by Corliss (1959, 1961, 1979). It is principally based on those of Corliss (1979) and Lee (2002).
An attempt has been made to keep the definitions or explanations succinct. However, brief descriptive comments have been added when terms are particularly complicated or important. Almost always we have included information identifying the taxo-nomic group or groups of ciliates that possess or show the character or trait being described. Cross-referencing is frequently employed, either directly or indirectly by italicizing selected words in the definition. We have tried to point out controversies, present alternative meanings, and give synonyms. Furthermore, we have indicated our own preferences. For many words derived from Greek or Latin, we have provided the suggested plural. If a plural is not provided, it is generally acceptable to add an “s” or “es” to the singular, as appropriate. A number of morphological features are illustrated in the figures at the end of this chapter, and are indicated by a direct reference to the labelled structure in the figure and its part (e.g., Kd, Fig. 2.1A).
