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.

Book Description
With an account of over 6.000 recent and 15.000 fossil species, phylum Bryozoa represents a quite large and important phylum of colonial filter feeders. This volume of the series Handbook of Zoology contains new findings on phylogeny, morphology and evolution that have significantly improved our knowledge and understanding of this phylum. It is a comprehensive book that will be a standard for many specialists but also newcomers to the field of bryozoology.

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
Bryozoans are aquatic animals that form colonies of connected individuals. They take a variety of forms: some are bushy and moss-like, some are flat and encrusting and others resemble lace. Bryozoans are mostly marine, with species found in all oceans from sublittoral to abyssal depths, but freshwater species also exist. Some bryozoans are of concern as marine-fouling organisms and invasive species, while others show promise as sources of anticancer, antiviral and antifouling substances. Written by experts in the field, Australian Bryozoa Volume 1: Biology, Ecology and Natural History is the first of two volumes describing Australia’s 1200 known species of bryozoans, the richest diversity of bryozoans of any country in the world. It contains chapters on the discovery of bryozoans, their morphology, classification and fossil history, their roles in biosecurity and marine benthic environments, and potential uses in biotechnology and ocean acidification. It provides an authoritative reference for biology students, academics and others interested in marine biology.

Book Description
This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.

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
Special Publication 485 About 40 million years after the Cambrian Explosion, the Great Ordovician Biodiversification Event (GOBE) represents a second and dramatic burst in marine biodiversity, with major changes in the structure of ecosystems and the progressive replacement of the distinctive Cambrian Evolutionary Fauna by the Paleozoic Evolutionary Fauna. However, the GOBE is not a single, worldwide, short-term event, but rather the complex sum of successive diversifications occurring in distinct taxonomic groups, trophic guilds and regions. This book focuses on the Late Ordovician Tafilalt Biota, Anti-Atlas Morocco, which provides a snapshot of the GOBE in high-latitude regions of the Southern Hemisphere. A series of contributions explore different aspects of the Tafilalt Biota, including its geological setting, the international fossil trade in this area and a series of detailed systematic contributions describing many new taxa of marine invertebrates. This volume represents a significant contribution to the understanding of the Tafilalt Biota and its significance to the GOBE.

Book Description
The nervous system is particularly fascinating for many biologists because it controls animal characteristics such as movement, behavior, and coordinated thinking. Invertebrate neurobiology has traditionally been studied in specific model organisms, whilst knowledge of the broad diversity of nervous system architecture and its evolution among metazoan animals has received less attention. This is the first major reference work in the field for 50 years, bringing together many leading evolutionary neurobiologists to review the most recent research on the structure of invertebrate nervous systems and provide a comprehensive and authoritative overview for a new generation of researchers. Presented in full colour throughout, Structure and Evolution of Invertebrate Nervous Systems synthesizes and illustrates the numerous new findings that have been made possible with light and electron microscopy. These include the recent introduction of new molecular and optical techniques such as immunohistochemical staining of neuron-specific antigens and fluorescence in-situ-hybridization, combined with visualization by confocal laser scanning microscopy. New approaches to analysing the structure of the nervous system are also included such as micro-computational tomography, cryo-soft X-ray tomography, and various 3-D visualization techniques. The book follows a systematic and phylogenetic structure, covering a broad range of taxa, interspersed with chapters focusing on selected topics in nervous system functioning which are presented as research highlights and perspectives. This comprehensive reference work will be an essential companion for graduate students and researchers alike in the fields of metazoan neurobiology, morphology, zoology, phylogeny and evolution.

Book Description
Increasing rate of species extinction in the present day will lead to a huge biodiversity crisis; eventually, this will lead to the paucity of non-renewable resources of energy making our Earth unsustainable in future. To save our mother planet from this crisis, studies need to be performed to discover abundant new fossil sites on Earth for continued access to oil-rich locations. Most importantly, a holistic approach is necessary in solving the present problem of biodiversity loss. This book presents newly developed quantitative models in understanding the biodiversity, evolution and ecology of extinct organisms. This will assist future earth scientists in understanding the natural and anthropogenic causes behind biodiversity crisis and ecosystem collapse. In addition, this study would be of great interest to exploration geologists and geophysicists in potentially unraveling natural resources from our sustainable Earth.
