Discusses systematics, ecology, and distribution of New Zealand's moas (flightless birds). Presents two theories of extinction: environmental catastrophe and human impact. Concludes that some moa species survived the Pleistocene epoch and primitive man completed the extinction process. (CK)

Directions are given for caring for desert tortoises, both adults and young. Observations of their behavior are recommended. (SA)

Discusses problems with reviews and criticisms of popular social science books: the quality and background of reviewers, the difficulty of distinguishing between fact and opinion, and the scarcity of competent reviewers. Analyzes reviews of Robert Ardrey's "African Genesis" and "The Territorial Imperative," Konrad Lorenz's "On Aggression," and…

Discusses various kinds of symbiosis including commensalism, protocooperation, mutualism. Examples are given of each, and emphasis is on the interdependence of living things. (SA)

Ideas intended for use in a high school biology laboratory are given. Swordtail fish are described as subjects for observation in animal behavior studies. (SA)

Discussed are some of the strategies required to try to detect and explain DNA markers that account for small amounts of behavioral variation. Situations in both animal and human behavior are described. The link between molecular biology and behavior is highlighted. (CW)

Comparison of social choices of trisomic macaques and of control groups found that groups showed few differences in preferences for stimulus animals with and without disabilities. Results suggest that the avoidance of individuals with disabilities is not a general primate trait and the presence of mental retardation and physical handicaps need not…

Activities are included that acquaint students with the parts of birds and the structure of feathers; that identify the prey of owls by opening owl pellets; working with information about threatened and endangered species of birds; and follow-up activities for bird study. A list of state and provincial birds of the United States and Canada and…

Presents an activity that allows students to observe crawling and swimming behavior in Lumbriculus variegatus, a freshwater oligochaete worm. Contains 12 references. (WRM)

Provides a protocol for examining the mechanisms of animal thermoregulation in a straightforward but more sophisticated manner than using a thermal gradient. Describes a methodology for conducting operant conditioning to examine thermal set points for ectothermic animals. Contains 20 references. (WRM)

Presents an active-learning technique in which students design their studies that was found to be successful in an animal behavior laboratory course. Divides the laboratory course into three components: (1) structured and technique-oriented exercises; (2) open-ended and student-designed investigations; and (3) independent projects. Explains…

Previous experiments have shown that unsignaled delayed reinforcement decreases response rates and resistance to change. However, the effects of different delays to reinforcement on underlying response structure have not been investigated in conjunction with tests of resistance to change. In the present experiment, pigeons responded on a…

Conducting observational investigations of behaviors and processes is an important method for generating scientific knowledge. This article describes a methodology for assisting students in the processes of observational inquiry and theory articulation and its instantiation in a set of digital video tools. We describe a high school biology…

It is important for educators to address the diverse learning styles that exist within the students found in their courses and to try new ideas. Different people have different ways of telling other people what they know. The authors of this article contend that it is vital to incorporate lesson plans/activities that address students who have…

In this interrupted case study, based on a journal article on the parenting behavior of American coots, students are given information and data from which they must develop hypotheses and design experiments, mimicking the way that scientists conduct research. The case is appropriate for courses in biology, especially those focusing on evolution…
