Book Description
Bryozoa are among the most abundant yet least understood of phyla in the fossil record. These exclusively colonial animals can be traced back to the Ordovician as fossils and are common elements of sediments deposited in shallow marine environments. On occasion their calcareous skeletons are sufficiently numerous to produce bryozoan limestones. The potential of bryozoans in facies analysis, and their use in macroevolutionary studies, have both been widely recognised, but to date have been incompletely exploited. Bryozoan Paleobiology brings together the scattered research on living and fossil bryozoans in broad and profusely illustrated overview that will help students and researchers alike in understanding this fascinating group of animals. Beginning with the basics of bryozoan morphology, ecology and classification, the book progresses from the smallest scale of skeletal ultrastructure, to the largest of bryozoan distributions in time and space. On the way, topics such as the origin of zooidal polymorphism and macroevolutionary trends in colony forms are covered. Case studies illuminate these topics, and areas in which further research is particularly required are highlighted.

Book Description
The authors argue that the growth pattern and form of the colony in many bryozoans is an adaptive strategy rather than a stable genetic character. "Bryozoan Evolution is profusely illustrated and has a bibliography of over 400 titles. It will find an appreciative audience of paleontologists, invertebrate zoologists, and ecologists thanks to its innovative and detailed evaluations of the roles of ecology, adaptive and functional morphology, life histories, biomechanics, developmental constraints, and chance on the evolution of the marine taxa of this speciose group."—Russel L. Zimmer, Science "This book is an excellent source of information on the functional morphology and variety of colonial architecture in bryozoans, very well illustrated, and worth reading at least twice."-Robert L. Anstey, Paleobiology "Even as one of the converted, I found the book a stimulating combination of paleobiology and ecology. In many ways it is a 'teaser'-the authors suggest a number of interesting hypotheses, and can test only some of them. Perhaps most important, McKinney and Jackson provide a plethora of fascinating ideas and examples that demonstrate the potential of this group of animals, and that should stimulate more work."-Michael S. Keough, TREE "This stimulating book is sure to promote further interest in bryozoans. It will appeal to biologists and paleontologists alike."-Paul Taylor, Times Higher Education Supplement

Book Description
Biology of Bryozoans covers some of the unusual and even unique systems and aspects of bryozoans. The book discusses the gametogenesis of bryozoans; the brooding patterns of bryozoans; and the structure and classification of gymnolaemate larvae. The text also describes the metamorphosis, ancestrulae, and coloniality in bryozoan life cycles; the ultrastructure, mineralogy, and development of bryozoan skeletons; and polymorphism in marine bryozoans. Bryozoan feeding and culture; experimental techniques and culture methods; and the problem of the funiculi and the communications are also considered. The book further tackles the aging process in bryozoans; the bryozoan nervous system; and taxes and tropisms of bryozoans. The text also looks into the life strategies of bryozoans; the population genetics of bryozoans; and the adaptive model for the evolution of the ectoproct life cycle. Zoologists, marine biologists, and students taking related courses will find the book invaluable.

Book Description
A selection of papers presented at the 13th International Conference of the International Bryozoology Association held in Concepción Chile in January 2004 and hosted by the Universidad de Concepción and Universidad Católica de la Santísima Concepción. The topics presented in this volume reflect the diversity of studies on bryozoa with authors from 18 countries. They include investigations in seven thematic areas: ecology and life strategies; recent and fossil faunas of Australia and New Zealand; past and present bryozoans from both Antarctic and Arctic seas; geology and palaeontology of bryozoans from Eurasia and North America; fresh water bryozoans around the world; fossil bryozoans of the Mediterranean and Tethyan realms and evolution and diversity of recent species. This volume represents the newest advances made in bryozoological studies during the last three years, and makes a significant contribution to the literature.

Book Description
Bryozoan Studies 2022 contains nineteen papers presented at the 19th International Conference of the International Bryozoology Association held at Trinity College Dublin in August 2022. Bryozoans are complex and fascinating colonial organisms that range from Cambrian to the present day and which are found in marine and freshwater environments from pole to pole and subtidal to abyssal. Recent tomographic techniques have revolutionised the study of modern and fossil taxa where internal structures are revealed through non-destructive methodologies. Here the internal structure of some Ordovician and Eocene taxa is illustrated through these methods. Phylogenetic studies of bryozoans question the classic classification of the group; here the phylogeny of species from California and Japan is described. Other topics covered are assessments of Recent faunas from Haiti and fossil assemblages from Mexico and the United States. Distributional patterns from the Arctic and New Zealand and the dispersal patterns of bryozoans on rafted pumice and on slipper lobsters are characterised. Further contributions provide descriptions of a rare Permian taxon, clarification of species assigned to the Upper Palaeozoic genus Stenopora, avicularia in Wilbertopora, enigmatic structures in a fenestrate bryozoan, repair structures in trepostomes, and an assessment of skeletonisation in the families of Palaeozoic orders.

Book Description
With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development. The contributors are Ann F. Budd, Efstathia Bura, Leo W. Buss, Mike Foote, Jörn Geister, Stephen Jay Gould, Eckart Hâkansson, Jean-Georges Harmelin, Lee-Ann C. Hayek, Jeremy B. C. Jackson, Kenneth G. Johnson, Nancy Knowlton, Scott Lidgard, Frank K. McKinney, Daniel W. McShea, Ross H. Nehm, Beth Okamura, John M. Pandolfi, Paul D. Taylor, and Erik Thomsen.

Book Description
Bryozoa are a colonial animal phylum with a long evolutionary history, having existed from the early Ordovician (480 My) onward and still flourishing today. Several mass extinctions in earth history shaped and triggered bryozoan evolution through drastic turnover of faunas and new evolutionary lineages. Bryozoa are widespread across all latitudes from Equator to Polar Regions and occur in marine and freshwater environments. They are shaping benthic ecosystems and recording ambient environmental conditions in their skeletons. The book provides a synthesis of the current main topics of research in the field of Bryozoology including combined research on both extant, and extinct taxa. Fields or current research span molecular genetics and phylogeny, life history, reproduction and anatomy, biodiversity and evolutionary patterns in time and space, taxonomy, zoogeography, ecology, sediment interactions, and climate response.
