Describes a laboratory practical on animal behavior suitable for senior secondary school or university biology classes. Several separate exercises relating to the house building behavior of caddis fly larvae are detailed, together with the time required for preparation. (JR)

Describes a classroom demonstration for training pigeons and showing many kinds of behavior after a stimulus is given. (PS)

With the establishment of the United Nations environmental secretariat at Nairobi, many opportunities are possible for biology teachers to improve their teaching, especially in areas of wildlife management and preservation. A group of educators will travel to African countries and prepare audio-visual and other instructional materials. (PS)

Reviews six new children's books on the topics of animals, biorhythms, and history of science. (GT)

Describes having a pot-bellied pig in a classroom. Students learned how to care for the pig and train it. Describes other animals in the classroom and the class putting on shows for other students. (PR)

Activities that consider the courtship behavior and mating patterns of millipedes are presented. The functional significance of a behavior that has evolved through indirect competition between males is discussed. The procedures for seven experiments, results, and interpretations are included. (KR)

An activity simulating natural selection in which wild birds are predators, green and brown pastry "baits" are prey, and trays containing colored stones as the backgrounds is presented. Two different methods of measuring selection are used to describe the results. The materials and methods, results, and discussion are included. (KR)

Most biology students have the opportunity to look at protozoa under the microscopes or keep mealworms in a bowl. They may manipulate the heart rate of "Daphnia" or calculate the respiration of plants. They may even grow corn in the spring or keep fish and a small rodent or two. But once the class hamster grows testy from being awakened every…

Described is the use of praying mantises as organisms to illustrate the concept of predator. (PEB)

Describes the use of a unit on arthropods as a device for helping children develop an awareness and appreciation of the living environment. (PEB)

Describes procedures for collecting and using cryptozoic invertebrates in introductory biology classes to develop interest in invertebrate ecology, behavior, physiology, morphology, and taxonomy. (PEB)

Experiments and demonstrations are presented which have been used in a high school course on animal behavior. Animals used include spiders, fish, birds, and mammals. (BB)

Through the use of learned symbols, two chimpanzees accurately specified 11 foods by name to one another when the food item's identity was known by only one and requested specific food of one another by name. Requests resulted in cooperative and reciprocal symbolically mediated food exchange. (Author/MA)

Discusses recent incidences of mammal strandings and relates the hypotheses that have been made to explain such occurrences. (MA)
