Excerpt from A Contribution to the Physiology of the Fresh-Water Sponges (Spongillidae): Proefschrift Ter Verkrijging Van Den Graad Van Doctor in De Plant-En Dierkunde Aan De Rijks-Universiteit Te Leiden, Op Gezag Van Den Rector-Magnificus, Dr. P. C. T. Van Der Hoeven, Hoogleeraar in De Faculteit Der Geneeskunde If I venture to treat here at large, with the help of my own research, the problem of the chlorophyll, of the current of water, of the ingestion and the defecation in fresh-water sponges, it is not, because there is but little known about these problems. On the contrary; investigators have already studied them since decennaries. We even possess a great number of papers on these subjects; some of which are considered in literature as standard researches giving decisive results. Nevertheless, I think it neces sary to treat those problems once more; in the first place, be cause during my investigations, which I have continued as exact as possible for at least 4 years, several of these results obtained and generally acknowledged some of them being of the greatest interest proved to me absolutely inexact; and in the second place, because I will be able to confirm by new and better proofs some of the results, which have not yet been generally acknow ledged in consequence of a less complete argumentation.

The authors "have intended to make the forefront of sponge research easily accessible to the nonspecialist, illustrating the state of the art of the field,and presenting current controversial issues. For the specialist, we wanted this monograph to be a handy, valuable update on the most recent advances in sponge science."--p. x

Racek seems to have authored much of this work after the death of J. T. Penney and undertook a study and review of Penny's huge colleciton of material and unpublished data at the recommendation of B. Theodore Cole of the University of South Carolina. In view of the voluminous material available, Racek found it imperative to revise all true gemmule-producing species rather than elaborate Penny's outlined account of the Meyeninae and as a result of the study, demonstrated the fallacy of a subdivision of the family Spongillidae by using gemmosclere characteristics.

Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May 1975. The symposium not only presents investigations, but also problem areas in the field of sponge biology. This book therefore shows that sponges are a very challenging and untouched subject area for future studies. This book is divided into three major parts, wherein the first part introduces and discusses sponge biology. The introduction and discussion include sponge biology principles, perspectives, and problems. The next two parts discuss cell and development biology, taxonomy, and ecology. Part 2 deals with several topics of the cellular aspect, including an analysis of reproduction in sponge populations and cytochemical studies of connective tissues in sponges. This part also looks into the cytological abnormalities in various normal and transformed cell lines. Part 3 describes the different types of sponge in their various habitats. Sponge feeding mechanisms, ecological factors controlling sponge distribution, and zoogeography of Brazilian marine Demospongiae are also discussed in this part. This book will be of important value to biology students and teachers. Specialists including zoologists, ecologists, comparative physiologists, and biologists will also benefit from this book.

Modem biology owes much to the study of favorable model systems which fa cilitates the realization of critical experiments and results in the introduction of new concepts. Examples of such systems are numerous and studies of them are regularly recognized by the scientific community. The 1983 Nobel Prize in Med icine and Physiology is a magnificent example in which com plants served as the experimental model. In a manner somewhat more modest, other biological systems have attracted recognition due to their critical phylogenetic position, or indeed because of their uniqueness which distinguishes them from all other organisms. Assuredly, among the whole assemblage ofliving organisms, sponges stand out as worthy of interest by scientists: they are simultaneously models, an important group in evolution, and animals unlike others. As early as the beginning of this century, sponges appeared as exceptional models for the study of phenomena of cell recognition. Innumerable works have been dedicated to understanding the mechanisms which assure the reaggregation of dissociated cells and the reconstitution of a functional individual. Today, re search on these phenomena is at the ultimate, molecular level. Through an as semblage of characteristics the sponges are, based upon all available evidence, the most primitive Metazoans. Their tissues-perhaps one can say their cell groups-are loosely assembled (they possess no tight or gap junctions), cell dif ferentiation appears highly labile, and they do not develop any true organs. But, they are most certainly Metazoans.

Animal Energetics, Volume 1: Protozoa through Insecta provides information pertinent to bioenergetics, which is the study of energy transformation in living systems that can be studied at various levels of biological organization, including organismic, population, as well as molecular and cellular. This book discusses the various facets of animal energetics. Comprised of 10 chapters, this book starts with an overview of the wide spectrum of trophic types found within the free-living Protozoa. This text then discusses the substantial differences that occur in the growth, respiration, and overall feeding activities of sponges. Other chapters consider the evolution of symbioses in platyhelminths and rhynchocoelans, which provides an opportunity to understand the physiological adaptations that are favored in their life cycle. This book discusses as well the data on energetics of predators, pests, and parasitoids. The final chapter deals with the inherent difficulties encountered in the estimation of bioenergetics components. Nutritionists, biologists, physiologists, and ecologists will find this book useful.
