Published by: Centre for Instructional Technology Development, University of Toronto at Scarborough. ISBN: 0-7727-6300-3 [This publication is an electronic, multimedia synthesis of the world’s invertebrate animals. Invertebrates make up about 95% of all known animal species, yet their diversity is far less known to the majority of people than those animals we call vertebrates. This dynamic programme illustrates the diversity of body form, adaptation and behaviour through summaries of the 34 phyla. The presentation is organised according to the inter-relationships among these groups, displayed on a tree chart showing the major directions in which invertebrates have evolved. For each phylum, the programme presents: general biological information; habitat; classification; basic morphology; life cycles; and biological importance. Contents include over 700 colour photographs representing all invertebrate types, original line drawings, and over 150 pages of text. Each phylum is accompanied by a computer-graded quiz. Invertebrate Phylogeny complements any standard textbook on Invertebrate Zoology or Biodiversity, but also serves as a stand alone instructional tool for the study of invertebrates in the classroom.] Further details, together with a demonstration of the CD may be downloaded from: http://www.utsc.utoronto.ca/~williamsdd/CDWebsite/index.htm

ISBN: 0-7727-6313-5 [This CD is a multimedia presentation of the world's coral reefs, including information on reef types, distribution, formation, and status. It also contains a comprehensive index of many of the species of vertebrates, invertebrates and plants associated with reefs and their organization into communities. This multidimensional programme features world maps, diagrammatic sections of reef types illustrated by underwater photographs, section quizzes and an interactive game illustrating the challenges of coral reef management. The CD contains hundreds of original colour photographs, line drawings and schematics which bring to life every aspect of the reef community; these are accompanied by numerous text descriptions. Coral Reefs is an ideal instructional instrument for educators and is an effective learning device for students and professionals who work with, or who want to know more about these fascinating systems.] Further details, together with a demonstration of the CD may be downloaded from: http://www.utsc.utoronto.ca/~williamsdd/CDWebsite/index.htm (Last updated: 1 September 2006) Back to Freshwater Ecology Lab's Homepage |
