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)

Radio tags to track wildlife have been used for years. However, such tagging of whales has been more complicated and less successful. This article explores the latest technology that is designed to give information over a long period of time. (MA)

This article examines the mechanisms of adaptation and acclimatization of animals to cold temperatures. The differences between the two processes are explained and terms are defined. Graphs and drawings illustrate the article. (MA)

An elementary analysis of a common textbook airplane problem is given, and then, as an illustrative example, the possibilities of this mechanism for animal navigation are briefly considered. (Author/MA)

These experiments are addressed specifically to the question of whether transituational transfer of immunizing and therapeutic effects will occur when these procedures involve responses and settings which are very different from those used in final testing. (Author/RK)

Papier-mache has traditionally been thought of as a quick, inexpensive and rough-finish type of activity for young children. At Lincoln Junior High, Wisconsin, papier-mache has evolved into a rather sophisticated form of sculpture. (Author/RK)

Provides suggestions for activities that focus on earthworms. Includes observational exercises on earthworms' reactions to light and touch. (ML)

Discusses use of computer simulation as an archeological tool for research and teaching involving the remains of prehistoric game animals to aid in understanding effects of various strategies of prehistoric hunters on populations of game animals. A simulation involving possible vicuna hunting strategies is described. (MBR)

Mammals that tolerate the winter cold and stay active all year exploit the harsh northern climate to their advantage. By simple experiments and observation you can better understand their adaptations which include furry bodies, snowshoe feet, extra blubber, light coloration, and strategically distributed food caches. (JHZ)

Provides background information (in outline form) on the bottlenose dolphin. Includes facts on characteristic anatomical and physiological features and highlights behavioral and communication patterns of dolphins. Also includes an explanation of ecolocation. (ML)

Explains how the wolf has been misrepresented in children's literature. (HOD)

Reviews a research study that examined zoo visitors' understanding of wildlife before and after zoo visits. Low posttest scores suggested that a zoo experience is regarded as a recreational outing rather than an educational event. Implications for educational improvement are presented. (ML)

Suggests various observations that can be made while at a zoo, including behavior of animals, adaptations to special environments, locomotion, food type, and physical characteristics. Provides a sample data sheet for animal observations, citing the usefulness of organized observation. (JM)

The value of the genus Nematodius in teaching is not widely realized. Presented is a brief biological outline of the organism (including geographical distribution and reproductive cycle/behavior) and its use in student investigation of selective predation. (Author/JN)
