Book Description
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.

Book Description
An illustrated guide to the sweeping diversity of crustacean larval forms. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Crustaceans—familiar to the average person as shrimp, lobsters, crabs, krill, barnacles, and their many relatives—are easily one of the most important and diverse groups of marine life. Poorly understood, they are among the most numerous invertebrates on earth. Most crustaceans start life as eggs and move through a variety of morphological phases prior to maturity. In Atlas of Crustacean Larvae, more than 45 of the world's leading crustacean researchers explain and illustrate the beauty and complexity of the many larval life stages. Revealing shapes that are reminiscent of aliens from other worlds—often with bizarre modifications for a planktonic life or for parasitization, including (in some cases) bulging eyes, enormous spines, and aids for flotation and swimming—the abundant illustrations and photographs show the detail of each morphological stage and allow for quick comparisons. The diversity is immediately apparent in the illustrations: spikes that deter predators occur on some larvae, while others bear unique specializations not seen elsewhere, and still others appear as miniature versions of the adults. Small differences in anatomy are shown to be suited to the behaviors and survival mechanisms of each species. Destined to become a key reference for specialists and students and a treasured book for anyone who wishes to understand "the invertebrate backbone of marine ecosystems," Atlas of Crustacean Larvae belongs on the shelf of every serious marine biologist.

Book Description
Generously illustrated, this essential handbook for herpetologists, ecologists, and naturalists features comprehensive keys to eggs, embryos, salamander larvae, and tadpoles; species accounts; a glossary of terms; and an extensive bibliography. The taxonomic accounts include a summarization of the morphology and basic natural history, as well as an introduction to published information for each species. Tadpole mouthparts exhibit major characteristics used in identifications, and the book includes illustrations for a number of species. Color photographs of larvae of many species are also presented. Handbook of Larval Amphibians of the United States and Canada, written by the foremost experts on larval amphibians, is the first guide of its kind and will transform the fieldwork of scientists and fish and wildlife professionals.

Book Description
Atlas of Marine Invertebrate Larvae, Second Edition covers the origins and history of marine larval science, contemporary state-of-the-art approaches to larval development and biology, and the highest-quality images and schematics showing the broadest diversity of marine larvae in the animal tree of life. This book illustrates larval body plans, the anatomy of their organ systems (muscular, sensory, digestive), including distinct ciliation patterns that facilitate swimming, and the complex metamorphic changes they undergo between different larval and growth stages. Each chapter contains in-text references that direct readers to both historical and contemporary research on the forms, functions, behaviors and biogeographical distributions of marine larvae.This book is a valuable and foundational resource for biologists across various disciplines, including biodiversity, biogeography, and developmental biology. Ecologists, taxonomists, oceanographers, and environmental scientists also benefit from the complete coverage of marine larval forms offered by this book. Additionally, the broad scope and phyletic coverage of marine biodiversity presented in this atlas is ideal for students in oceanography and marine biology, animal development, biological oceanography and invertebrate zoology. - Covers every major marine invertebrate clade within the Metazoa - Includes an expanded introductory chapter on the biology, ecology and roles of larvae in marine food webs and the movements of marine invertebrate species within the world's oceans - Provides complete updates to each chapter, including condensed, comparative background information on taxon-specific development and life-history patterns - Features detailed anatomical schematics and drawings, accompanied by compound, confocal and scanning electron micrographs for multiple recognized clades within each phylum

Book Description
This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the singlecelled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution. The book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

Book Description
The third edition of this popular introductory text maintains the character that won worldwide respect for its predecessors but features a number of enhancements that broaden its scope, increase its utility, and bring the treatment thoroughly up to date. It provides complete coverage of the statistical ideas and methods essential to students in agriculture or experimental biology. In addition to covering fundamental methodology, this treatment also includes more advanced topics that the authors believe help develop an appreciation of the breadth of statistical methodology now available. The emphasis is not on mathematical detail, but on ensuring students understand why and when various methods should be used. New in the Third Edition: A chapter on the two simplest yet most important methods of multivariate analysis Increased emphasis on modern computer applications Discussions on a wider range of data types and the graphical display of data Analysis of mixed cropping experiments and on-farm experiments

Book Description
Immature Insects, Volumes 1 and 2, edited by Frederick W. Stehr, are excellent sources of information on the biology and ecology of insect families, making these indispensible textbooks. With abundant illustrations, descriptions, and keys, both volumes are also useful as field guides in identifying many common, economically important, or unusual species. Immature Insects is the only reference that extensively details information necessary to identify immature insects. These books explain the techniques for collecting, rearing, killing, preserving, storing, studying, and shipping insects. Well-illustrated keys are provided for all orders and families.
