Subject: Reef Fishes Rory Dickinson, I am not really sure what level of input you are looking for relative to your question on reef fish habitat utilization. However, if you will be using the information for classroom teaching at the college or secondary level, we have a CD-ROM (Coral Kingdom 1.1) which describes the role of habitat as a limiting factor to reef fish community structure as well as illstrates adaptations in fishes and invertebrates and explores many kinds of interrelationships between organisms/environment. The software is ideally suited for units on the coral reef or to demonstrate the concepts of form and function in adaptations, interrelationships between organisms and habitat, competition, predator avoidance, energy and materials cycles and human impacts in general biology or introductory environmental science, biodiversity or ecology courses. Although this CD specifically features tropic Pacific species, there are certainly analogs with Atlantic which share the same sensory, locomotor and feeding adaptations. You can look at Coral Kingdom in the CyberLearning Collection at http://www.cyberlearn.com or give us a call at (800) 499-3322 Sorry if this is too commericial for this list. At least I kept it short! Ron S. Nolan Digital Studios/CyberLearning Collection Excerpt from recent review in NABT's THE AMERICAN BIOLOGY TEACHER, VOLUME 58, NO. 6, SEPTEMBER 1996 "This is the best software I have seen that uses inquiry learning for principles of ecology combined with outstanding photography of coral reef inhabitants. The student has to work to collect data and draw conclusions. Each mission has a different purpose so that the software can be used several several times to explore ecological concepts. The same mission can be used several times by asking different questions to collect new information for understanding ecological principles. My only complaint, and it is trivial, is that the "hot spots" on the organisms are a little small and could be missed by the student. The "hot spots" calls up the scientific and common name for each species in the view during a dive. I strongly recommend Coral Kingdom to teachers who use inquiry teaching and are looking for a simulation that teaches solid ecological principles. I would also recommend the software just as a teaching aid for the coral reef communities. This will make a good addition for use in both classroom and lab situations." George C.
