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.

This is the first coherent description of all levels of communication of ciliates. Ciliates are highly sensitive organisms that actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences show us that this is possible owing to sign(aling)-mediated communication processes within ciliates (intra-organismic), between the same, related and different ciliate species (inter-organismic), and between ciliates and non-ciliate organisms (trans-organismic). This is crucial in coordinating growth and development, shape and dynamics. This book further serves as a learning tool for research aspects in biocommunication in ciliates. It will guide scientists in further investigations on ciliate behavior, how they mediate signaling processes between themselves and the environment.

This is the second book of a series treating the hypotrichs, a major part of the spirotrichous ciliates. It summarises 230 years of morphological, morphogenetic, faunistic, and ecological data, heretofore scattered in some 1,300 references around the world. The book provides taxonomists, cell biologists, and ecologists with a thorough survey supplying synonyms, nomenclature and systematics, and an extensive description of morphology and ecology, including almost all published records, for each species.
