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

Suggests and describes laboratory activities in which the Mexican axolotl (Ambystoma mexicanum Shaw) is used, including experiments in embryology and early development, growth and regeneration, neoteny and metamorphosis, genetics and coloration, anatomy and physiology, and behavior. Discusses care and maintenance of animals. (CS)

The neuronal model shown to code sound-source azimuth in the barn owl by H. Wagner et al. in 1987 is used as the basis for a speculative brain-based human model, which can establish contrastive phonetic categories to solve the problem of perception "non-invariance." (SLD)

Presents Attachment Q-Set adapted for study of monkeys as described by Kondo-Ikemura and Waters in this issue. (HTH)

Presents scoring key for the original Attachment Q-Set and that adapted for study of secure-base behavior of monkeys, as described by Kondo-Ikemura and Waters in this same issue. (HTH)

Introduces the topic of father-adolescent relationships along with two basic models of fatherhood. The first is of the father who does not take an active role in the upbringing of his children but who assumes responsibility to protect and provide for them; second is of the father who may be flexible, i.e., more involved, in response to varying…

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)

Comments on Gauvain's discussion, in this issue, of the development of thinking from a sociocultural perspective, expanding her analysis by comparing research on apes who have developed in natural habitats with apes raised by humans in something resembling a human culture. Argues that the study of nonhuman primates can contribute to the emerging…

This case study examined the development of language skills in a bonobo and a chimpanzee raised by human caregivers since infancy, focusing on the primates' ability to comprehend simple speech, understand referential symbol use, and engage in intentionally communicative routines. It is argued that comparative results from these primates can…

In a study of interspecies understanding, 75 naive human listeners classified 18 vocalizations of monkeys into 1 of 7 semantic categories, which were also related to the behavioral situation. Results suggest that both species share vocalization patterns signalling fear, aggression, dominance, and emotional neutrality. (45 references) (LB)

Examines to what extent, and in what ways, speech is unusual and how it compares to other semiotic systems. Discusses language and speech, neurolinguistic processing, comparative vocal/auditory abilities, primate evolution, and semiogenesis. (SR)

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)

Presents a directed-inquiry activity to take students one step beyond observation of how living organisms capture prey. Uses a field lab based upon predator-prey relationships to enliven the teaching of food web concepts to non-science-major freshman undergraduates. Can also be used in teaching high school biology students through college science…

Presents a biology laboratory experiment designed to examine the ability of fish to improve their foraging rate with experience. This project is appropriate for ecology and animal behavior courses as well as introductory biology courses with a component that provides students with experience in designing and conducting scientific experiments.…
