Summary: he third edition of Animal Diversity presents a survey of the animal kingdom with emphasis on diversity, evolutionary relationships, functional adaptations, and environmental interactions. It is tailored for a one-semester or one-quarter course and is appropriate for both non-science and science majors. Edition/Copyright: 3RD 03
New to This Edition :
- Chapter 2 covering ecology is new to this third edition. It exp ...show morelains the principles of ecology, with emphasis on populations, community ecology, and variations in life history strategies of natural populations. The treatment includes discussions of niche, population growth and its regulation, limits to growth, competition, energy flow, and nutrient cycles.
- The sixteen survey chapters of animal diversity that form the central theme of this book are prefaced by four chapters with discussions of the principles of evolution, ecology, classification, and animal architecture. Throughout this revision references have been updated and the writing style has been simplified and streamlined.
- Chapter 5 on protozoan groups was completely revised for this edition. Molecular sequencing of bases in genes has revealed that the former phylum Protozoa embraces numerous phyla of varying evolutionary relationships. These groups of animal-like unicellular eukaryotes are grouped in this chapter as a convenience without implying that they form a monophyletic group.
- Chapter 8 (acoelomate animals) features a rewritten section on turbellarians to emphasize their paraphyly, yet retaining the class Turbellaria to avoid the objectionable taxonomic complexity that strict cladistic analysis would require.
- While still covering all pseudocoelomates in a single Chapter 9, the authors now group the various phyla in superphyla Lophotrochozoa (Rotifera, Acanthocephala, Gastrotrica, and Entoprocta) and Ecdysozoa (Nematoda, Nematomorpha, Kinorhyncha, and Priapulida).
- In the phylogeny section of chapter 12 (arthropods) we revisited the Lophotrochozoa-Ecdysozoa question, as well as the possibility of polyphyly of Arthropoda, and the new hypothesis that myriapods are a sister group to all other arthropods and that insects and crustaceans form a monophyletic group.
- Chapter 13 (lesser protostomes) was reorganized to group lophotrochozoans (Sipuncula, Echiura, Pogonophora, Brachiopoda, Ectoprocta and Phoronida) and ecdysozoans (Pentastomida, Onychophora, Tardigrada, and Chaetognatha) together. Chaetognatha were transferred to this chapter on the strength of evidence that they are protostomes, despite their morphological similarities with deuterostomes. Molecular evidence strongly supports placement of lophophorate phyla in Protosomia, and division of their coelom similar to deuterostomes must be convergent.
- In chapter 15 (vertebrate beginnings) the authors revised and shortened discussions of pharyngeal filter-feeding, ancestry and evolution of chordates, and Garstang's hypothesis of larval evolution.
- The many changes in chapter 16 (fishes) include a revision of origin and evolution of fishes, and fish classification. In current classifications the traditional term Osteichthyes as applied to all bony fishes does not describe a monophyletic grouping; rather the two major lineages of bony fishes are now divided into two classes containing ray-finned fishes (Actinopterygii) and lobe-finned fishes (Sarcopterygii).
- In chapter 19 (birds, the section covering evolution has been revised to explain the recently adopted division of living birds into paleognathous and neognathous groups, replacing the older terminology of ratite and carinate to describe flightless and flying birds respectively.
- Among the many changes in chapter 20 (mammals) are revisions of the sections on horns and antlers, glands, food and feeding, primate classification, and human evolution.
- Covers the "heart" of a zoology course: a complete discussion of animals (protozoa to mammals). These chapters are preceded by an introduction to classification, evolution and animal architecture.
- Author recognition- Professors and students can depend on accurate, experienced writing, knowing the tradition of quality work by these authors.
- Length: Half the size of standard Zoology texts.
- Level: Appropriate for intermediate level courses needing an abbreviated version of the longer Hickman titles.
- Classification: Taxonomy is presented with both the Linnaean system and with cladistics via cladograms. Students and professors both benefit by having both systems presented in the text. Students are better prepared by studying both. The material on cladistics can be easily skipped if so desired by the instructor.
- This text contains modern, thoroughly researched coverage of the phyla of animals. It emphasizes the unifying architectural and functional themes of each group.
- Descriptions of appropriate web links appear at the end of every chapter.
- VALUE- the most concise and least expensive book in the market.
