Annelida is a diverse group of animals, commonly referred to as segmented worms and currently comprising around 14000 described species. Found in most marine and freshwater areas, annelids have also successfully occupied many subterranean habitats. This volume documents annelid reproduction in the context of their phylogenetic relationships. It pre

This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.

Students and naturalists are not only interested in which species live on the seashore but also about their biology. How does a particular species reproduce? What is its life cycle? A Student's Guide to the Seashore is a unique, concise, illustrated guide to both the biology and identification of over 600 common and widespread shore animals and plants. In this new edition, for the first time, simple keys are included to allow accurate identification, and each species is beautifully illustrated by the author's line drawings. Together with concise summaries of diagnostic features, and notes on biology, this is the first comprehensive guide to the seashore giving a fascinating insight into the diversity and complexity of life on the shore. An extensive glossary of scientific terms and complete bibliography ensure that this book will be the premier biological text and identification guide for many years to come.
