Ciliated Protozoa

distances between groups of ciliates were as vast as significant hurdles to obtain copyright permissions the genetic distances between plants and animals for the over 1,000 required illustrations, and I put - THE major eukaryotic kingdoms at that time! the publication schedule ahead of this element. I continued to collaborate with Mitch, and in There are a number of significant illustrated guides 1991 my first 'molecular' Magisterial student, to genera and species that have recently been pub- Spencer Greenwood, published an article estab- lished. References are made to these throughout lishing 1990 or thereabouts as the beginning of the book as sources that readers can consult for this the 'Age of Refinement' - the period when gene aspect of ciliate diversity. A future project that I am sequencing techniques would deepen our under- contemplating is an illustrated guide to all the valid standing of the major lines of evolution within ciliate genera.
