The Origins of Larvae

The Origins of Larvae PDF Author: D. Williamson
Publisher: Springer Science & Business Media
ISBN: 9401703574
Category : Science
Languages : en
Pages : 271

Book Description
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.

Zooplankton of the Atlantic and Gulf Coasts

Zooplankton of the Atlantic and Gulf Coasts PDF Author: William S. Johnson
Publisher: JHU Press
ISBN: 1421407469
Category : Science
Languages : en
Pages : 470

Book Description
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

Ecology of Marine Invertebrate Larvae

Ecology of Marine Invertebrate Larvae PDF Author: Larry McEdward
Publisher: CRC Press
ISBN: 0429610548
Category : Science
Languages : en
Pages : 485

Book Description
This is the first book to provide a detailed treatment of the field of larval ecology. The 13 chapters use state-of-the-art reviews and critiques of nearly all of the major topics in this diverse and rapidly growing field. Topics include: patterns of larval diversity, reproductive energetics, spawning ecology, life history theory, larval feeding and nutrition, larval mortality, behavior and locomotion, larval transport, dispersal, population genetics, recruitment dynamics and larval evolution. Written by the leading new scientists in the field, chapters define the current state of larval ecology and outline the important questions for future research.
