Protozoa may be found in almost every aquatic habitat, each containing dozens of species. The diversity can provide invaluable insights into the nature of the habitat. Protozoa can thus be used to illustrate biological principles.This colour guide makes the identification of individual protozoa easily accessible to students and professionals and provides information on protozoan communities found in different environments by means of a wealth of colour photomicrographs supported by...

The experience which has led to the writing of this book began in 1929 when, examining a species related to Utricularia gibba, I made an observation of some importance in understanding the mechanism of the trap. This begot a desire to study as many other species of the genus as I could obtain for comparison, primarily to determine the validity of my conclusions. My feeling that research in this field was promising was strengthened by the discovery that the pertinent literature was singular...

Sauropods, those huge plant-eating dinosaurs, possessed bodies that seem to defy every natural law. What were these creatures like as living animals and how could they reach such uniquely gigantic sizes? A dedicated group of researchers in Germany in disciplines ranging from engineering and materials science to animal nutrition and paleontology went in search of the answers to these questions. Biology of the Sauropod Dinosaurs reports on the latest results from this seemingly disparate gro...

Now published by Academic Press and revised from the author's previous Five Kingdoms Third edition, this extraordinary, all inclusive catalogue of the world's living organisms describes the diversity of the major groups, or phyla, of nature's most inclusive taxa. Developed after consultation with specialists, this modern classification scheme is consistent both with the fossil record and with recent molecular, morphological and metabolic data. Generously illustrated, now in full color, Kin...

As well as being a culture environment for fish and crustaceans, an aquaculture pond is a rich and complex ecosystem that is dominated by the microbial community. The community is nourished by food and sunlight, and is made up of algae, bacteria and, importantly, protozoa. Protozoa live by eating other organisms and detritus, or by absorbing soluble organic matter dissolved in the water. Ultimately they affect water quality in aquaculture ponds, including the stability of algal and bacterial ...

A new textbook on the practical use of dental materials suitable for undergraduate dental students and qualified dental practitioners taking post-graduate exams in dental materials, restorative dentistry, operative techniques, advanced conservative dentistry, endodontics, removable prosthodontics and implantology. - Highly practical and evidenced-based throughout – closing the gap between theory and practice to give readers confidence in selecting and preparing the right material for the p...

More than three hundred million years ago—a relatively recent date in the two billion years since life first appeared—vertebrate animals first ventured onto land. This usefully illustrated book describes how some finned vertebrates acquired limbs, giving rise to more than 25,000 extant tetrapod species. Michel Laurin uses paleontological, geological, physiological, and comparative anatomical data to describe this monumental event. He summarizes key concepts of modern paleontological resear...

Identifying Marine Phytoplankton is an accurate and authoritative guide to the identification of marine diatoms and dinoflagellates, meant to be used with tools as simple as a light microscope. The book compiles the latest taxonomic names, an extensive bibliography (referencing historical as well as up-to-date literature), synthesis and criteria in one indispensable source. Techniques for preparing samples and containing are included as well as hundreds of detailed, helpful information. Id...

This valuable reference delineates the ground water quality concerns associated with the planning and usage of septic tank systems. Septic tank systems represent a significant source of ground water pollution in the United States. Since many existing systems are exceeding their design life by several-fold, the usage of synthetic organic chemicals in the household and for system cleaning is increasing, and larger-scale systems are being designed and used.

The Evolution of Vertebrate Design is a solid introduction to vertebrate evolution, paleontology, vertebrate biology, and functional, comparative anatomy. Its lucid style also makes it ideal for general readers intrigued by fossil history. Clearly drawn diagrams illustrate biomechanical explanations of the evolution of fins, jaws, joints, and body shapes among vertebrates. A glossary of terms is included."A luminous text is matched by lucid drawings rationally placed. . . ....
