Title

Study of population density and morphological details of Vorticella convallaria in freshwater ponds of Nashik district, (M.S), India

Abstract

Vorticella Linnaeus, 1767 was the earliest genus name in use for a peritrich and is one of the most common and important groups of ciliates, inhabiting all marine, freshwater and terrestrial biotopes (Corliss 1979; Foissner et al. 1992; Lynn 2008; Sun et al. 2005; Warren 1986). The genus belongs to the family Vorticellidae, a morphologically distinct group within the subclass Peritrichia. Vorticella was erected by Linnaeus (1767) to include microscopic “animacules” with a stalk of some sort and a bell-shaped body crowned with a large oral area surrounded by cilia. Ehrenberg (1838) revised and redefined the genus, restricting it to non-colonial peritrichs with a helically contractile stalk. Over the next 100 years, many species of Vorticella were described and some obviously did not conform to Ehrenberg’s definition of the genus. Noland and Finley (1931) removed all of the clearly unacceptable species, and Foissner and Schiffmann (1974) removed species with a reticulate pattern of silverlines to the genus Pseudovorticella, leaving Vorticella relatively homogeneous in terms of morphology. The body shape, size, appearance of the peristomial lip, features of the pellicle surface and stalk, pattern of infraciliature, and number of silver-lines are characteristics typically used to characterize and identify species of Vorticella. The small sizes of many species of Vorticella, some of which have a cell body that is only 10-30m long, make it difficult to isolate them and describe the morphological features essential for taxonomic analysis. As a result, less than one-third of more than 200 species, infra species, varieties or forms that were designated in the genus have been described using modern morphological methods. Historically, Vorticella was considered to be a well-defined group based on morphological characteristics.
