Download or read book Graptolite Paleobiology written by Jörg Maletz and published by John Wiley & Sons. This book was released on 2017-05-08 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The graptolites constitute one of the geologically most useful taxonomic groups of fossils for dating rock successions, understanding paleobiogeography and reconstructing plate tectonic configurations in the Lower Palaeozoic. Graptolites were largely planktic, marine organisms, and as one of the first groups that explored the expanses of the world’s oceans are vital for understanding Palaeozoic ecology. They are the best and often the only fossil group for dating Lower Palaeozoic rock successions precisely. Thousands of taxa have been described from all over the planet and are used for a wide variety of geological and palaeontological (biological) research topics. The recent recognition of the modern pterobranch Rhabdopleura as a living benthic graptolite enables a much better understanding and interpretation of the fossil Graptolithina. In the decades since the latest edition of the Graptolite Treatise, the enormous increase of knowledge on this group of organisms has never been synthesised in a compelling and coherent way, and information is scattered in scientific publications and difficult to sort through. This volume provides an up-to-date insight into research on graptolites. Such research has advanced considerably with the use of new methods of investigation and documentation. SEM investigation and research on ultrastructure of the tubaria has made it possible to compare extant and extinct taxa in much more detail. Cladistic interpretation of graptolite taxonomy and evolution has advanced the understanding of this group of organisms considerably in the last two decades, and has highlighted their importance in our understanding of evolutionary processes. This book will show graptolites, including their modern, living relatives, in a quite new and fascinating light, and will demonstrate the impact that the group has had on the evolution of the modern marine ecosystem. This book is aimed not only at earth scientists but also at biologists, ecologists and oceanographers. It is a readable and comprehensible volume for students at the MSc level, while remaining accessible to undergraduates and non-specialists seeking up-to-date information about this fascinating topic in palaeobiology.

Download or read book Marine Decapod Crustacea written by Gary C.B. Poore and published by CSIRO PUBLISHING. This book was released on 2023-01-23 with total page 929 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decapod crustaceans, shrimps, crabs, prawns and their allies are highly visible and important members of marine environments. They are among the most charismatic of marine animals, inhabiting beaches, rocky shores and the deep sea, hiding under stones, burrowing in the sediment and nestling in among algae and many other microhabitats. However, most are difficult to identify by the specialist and amateur naturalist alike. Marine Decapod Crustacea explains the anatomical features necessary for differentiating taxa and includes diagnoses and identification keys to all 189 families and 2121 genera of marine Decapoda. Many decapods have vivid colours, which are showcased in a selection of spectacular photographs of many representative species. This volume provides an entry to the literature for taxonomists, naturalists, consultants, ecologists, teachers and students wanting to identify local faunas and understand this diverse group

Available in PDF, EPUB and Kindle. Book excerpt: Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.
