Discusses various bioethical issues and problems related to animal welfare and animal rights. Areas examined include: Aristotelian views; animal welfare legislation; Darwin and evolutionary theory; animal and human behavior; and vegetarianism. A 14-point universal declaration of the rights of animals is included. (JN)

Traces the history of the antivivisection movement, examining issues related to the use of animals in studying the cause of rabies. Also discusses issues related to the current controversy over animal experimentation. (JN)

Assesses dimensions of the threatened-species problem (by contrast with the way it has been handled in the past) and suggests some directions for urgent research if the problem is to be confronted in its proper scope and scale. Among topics addressed are the biological, genetic, and ecological attributes of species. (JN)

Both humans and animals live in a rich world of events. Some events repeat themselves, whereas others constantly change. The authors propose that discriminating this stability, sameness, and uniformity from change, differentness, and diversity is fundamental to adaptive action. Evidence from many areas of behavioral science indicates that the…

Speculates why animals have not developed wheels in place of inefficient legs. One study cited suggests three reasons why animals are better off without wheels: wheels are efficient only on hard surfaces, limitation of wheeled motion due to vertical obstructions, and the problem of turning in spaces cluttered with obstacles. (JN)

Surveys careers in working with animals and gives suggestions for use of this topic in the classroom. Activities involve identifying reasons for choosing any career, careers involving animals (traditional and nontraditional), community personnel, and pros and cons of animal careers. Two student activity sheets are included for duplicating. (DH)

Various examples of communication in species ranging from bumble bees to dolphins are examined in this paper. Focus is directed to indications of the cognitive ability of each species. The signals of cognition include evidence of: adaptability to a new situation; long term memory; and the property of displacement. Most of the sources reviewed…

Information on bats is provided, focusing on their diversity and distribution, characteristics, food habits, activities, roosting and social habits, reproduction, number of young and size at birth, hibernation, mortality and longevity, and movements and navigation. Additional information related to public health/disease concerns and bat management…

Water striders are insects that walk and run on the surface of water. Discusses the morphology, physiology, and behavior of these insects. Includes diagrams of stages in the movement of a typical strider. (JN)

Explores the mathematical abilities of human infants compared with various species of animals. Studies indicate that human infants enter the world capable of doing simple mathematical operations. Nonhuman animals can discriminate among sets of objects based on the number of items in each set. Further studies may pinpoint the age at which children…

This collection of pamphlets and articles reprinted from other National Anti-Vivisection Society (NAVS) publications was compiled to address the issues of classroom laboratory dissection and the use of animals in science fair projects. Three of the pamphlets contained in this packet are student handbooks designed to help students of elementary,…

"Eukiefferiella" and "Tvetenia" are closely related genera belonging to the subfamily Orthocladiinae within the Chironomidae, a family of non-biting midges. All known larvae in these genera are aquatic, being found predominantly in running water. Most species prefer cold, swift-flowing, well-oxygenated streams. Although larvae…

Presents an annotated list of 34 animals and 32 plants which are candidates for a list of the top 10 endangered species. Also presents the criteria used to formulate these lists. They include the conservation value (urgency prominance, biological value) and operational considerations (such as cost factors) for each species. (JN)

Addresses the problem of cruelty to animals from a research perspective. Studies of possible causes of childhood cruelty to animals are reviewed and common contributing environmental factors are identified. Implications for educators are discussed and directives for detection and prevention of cruelty are suggested. (ML)

The renin-angiotensin system (RAS) maintains salt and water balance. Discusses functions of the RAS as defined in mammalian species, considering how the system arose and what its original function was. Also discusses where some of the changes occurred in the system (and why) as well as other topics. (JN)
