Biofouling organisms are marine organisms that affix themselves to navigational buoys, floating docks, and pilings. Techniques for collecting these organisms for classroom use are described. General background information on the organisms and a list of common species are included. (JN)

Discusses the earth's biosphere, considering how the microbial, animal and plant life (which make up the biosphere) are sustained by the earth's lithosphere, hydrosphere, and atmosphere. Also considers how these three earth features have powerfully shaped the evolution of these organisms. (JN)

Reviews methods for obtaining accurate and reproducible results in determining zonation patterns on rocky shores. (CS)

Focusing on the question, "Can chimpanzees produce new sentences or merely sequences?" Terrace describes his efforts to teach the chimpanzee Nim to communicate through sign language. From his results, and the Gardners' experiments with Washoe, he concludes that no proof yet exists that chimpanzees can use language as humans do. (SJL)

Presents the viewpoints of a prominent behavioral scientist concerning the role of the environment in the evolution of behavior. (CS)

Included is information regarding: student construction of Newton's Discs to demonstrate color and of paper helicopters to encourage inquiry; improvising an apparatus demonstrating pressure between two bubbles; animal behavior experiments involving woodlice; two experiments using electronics freezer spray; chromatography of dyes; leaf keys; an…

The regulation (voluntary and involuntary) of animal care and use throughout history in research and teaching is reviewed. The role of several organizations concerned with various aspects of animal quality, care, and use is discussed. (BH)

Describes a constant-temperature observation chamber and includes instructions on constructing the apparatus. Suggestions for use are given as well as problems that might be encountered. (Author/SA)

Diagrams and explains construction of an actograph which quantitatively records daily movements of animals for a 24-hour period. Combines use of a kymograph and the teetering box of Palmer. Biorhythm activities with fiddler crabs, cockroaches, and hamsters are suggested. (CS)

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli. (Author/RK)

The need to expand graduate programs in veterinary medical education is described and suggestions are offered for developing curricula. It is noted that the comparative training in species approach of veterinary schools provides a basis for launching expanded graduate programs. (LBH)

A competency-based curriculum was designed by faculty members from the College of Veterinary Medicine and the College of Education at the University of Georgia. Results of the pilot program indicate that a curriculum does not greatly affect academic achievement. Specific findings are discussed. (LBH)

In view of the continuing need for and scarcity of large animal veterinary care in rural areas, this study tried to delineate those factors that delimit veterinary services. The problem was found largely to be tied to the practitioner's unwillingness to leave his office due to economics, professional dedication, and maintenance of professional…

This study assessed and compared the practitioner's role as perceived by participating practitioners, college program coordinators, college administrators, associate practitioners, and former students. Significant differences in perceptions of the practitioner's role were found. (LBH)

Compared comprehension of novel communicative signs to assist 2.5- and 3-year-old humans, chimpanzees, and orangutans find hidden objects during a hiding-finding game. Found that children at both ages performed above chance with all signs. No ape performed above chance for any signs not known before the experiment despite three times as many…
