Download or read book The Origin and Evolution of Larval Forms written by Brian K. Hall and published by Gulf Professional Publishing. This book was released on 1999-01-12 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: A classic problem in evolutionary biology is the origin of larvae - how and why did they occur? Indeed, it has often been suggested that many entirely unique body plans first originated as retained larvae of ancestral organisms. But what of the larvae themselves? What developmental and evolutionary forces shape and constrain them? These questions and others are dealt with by this international team of leading zoologists and developmental biologists. Intended to contribute to a continuing dialectic, this book presents diverse opinions as well as manifold conclusions. Certain to challenge and intrique, The Origin and Evolution of Larval Forms should be a part of the library of every evolutionary and developmental biologist interested in larvae and their significance.

Download or read book When do fishes become juveniles? written by G.H. Copp and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metamorphosis and the transition from larvae or embryos to juveniles in fishes are important in order to answer, for example, questions about: (1) life-history styles and their modifications in evolutionary perspective and within current environmental demands; (2) the development and application of fisheries recruitment models, (3) the use of ontogenetic scales for interspecific comparisons, (4) the identification of ontogenetic shifts in resource use, and (5) the discovery of evolutionary interrelationships of species or genera. This volume is dedicated to recent studies and reviews of existing knowledge on this insufficiently-addressed area of ichthyology. Most of the papers in this volume were presented in Bratislava, Slovakia, at the 1st International Workshop of the Fish Ontogeny Network of Europe (FONE) in September 1997, a meeting sponsored in part by the European Commission. This volume emphasizes an integrated approach to the study of fish ontogeny, which is a process during which one event is related to another and everything is related to everything else, encompassing physiology, morphology, behaviour and niche. Within this comprehensive perspective, the papers in this volume are grouped along four major themes: reflections on early ontogeny and metamorphosis, organism-environment relationships, ontogeny of predator-prey interactions, and behaviour and ontogeny. Among other issues, the papers consider topics such as whether one can identify when fish metamorphosis ends, whether the larva period begins with hatching or with the onset of exogenous feeding, whether fish ontogeny is `saltatory' or `gradual', and whether larvae are eliminated in some fishes with direct development. The keynote paper of this volume reviews the main topics within contemporary paradigms and the final paper concludes that the onset of the juvenile period can be identified in some species, but precision remains problematic, emphasizing the need for further research in this dynamic area of fish biology.

Download or read book Zooplankton of the Atlantic and Gulf Coasts written by William S. Johnson and published by JHU Press. This book was released on 2012-11-15 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beautifully illustrated, this is the only identification guide to zooplankton of the Atlantic and Gulf Coasts. Zooplankton are critical to the vitality of estuaries and coastal waters. In this revised edition of Johnson and Allen's instant classic, readers are taken on a tour of the miniature universe of zooplankton, including early developmental stages of familiar and diverse shrimps, crabs, and fishes. Zooplankton of the Atlantic and Gulf Coasts details the behavior, morphology, and coloration of these tiny aquatic animals. Precise descriptions and labeled illustrations of hundreds of the most commonly encountered species provide readers with the best source available for identifying zooplankton. Inside the second edition • an updated introduction that orients readers to the diversity, habitats, environmental responses, collection, history, and ecological roles of zooplankton • descriptions of life cycles • illustrations (including 88 new drawings) that identify 340-plus taxa and life stages • range, habits, and ecology for each entry located directly opposite the illustration • appendices with information on collection and observation techniques and citations of more than 1,300 scientific articles and books

Download or read book Larvae and Evolution written by D. Williamson and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many biological facts are irreconcilable with the assumption that larvae and adults evolved from the same genetic stock. The author of this book draws attention to these, and presents his alternative hypothesis that larvae have been transferred from one taxon to another. In his previous book (Larvae and Evolution, 1992), the author used larval transfer to explain developmental anomalies in eight animal phyla. In the present book, he claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa. This leads to a new, comprehensive theory on the origin of embryos and larvae, replacing the discredited 'recapitulation' theory of Haeckel (1866). Metamorphosis, previously unexplained, represents a change in taxon during development.
