Discusses the cultural role that scientific thought has historically played in relation to social theories, and the increasing influence of biology, ethology, and ecology on social models. (MLH)

Examines aspects of competitive exclusion, which develops when two species jointly utilize a vital resource that is in short supply. When this occurs, one of the species will eventually eliminate the other from the habitat where their distributions overlap, unless one or both species evolve differences that reduce competition. (JR)

Outlines an experimental course for non-science majors that concentrates on science-related community problems. Some of the topics explored by the students are explained. Five schools and 400 students are involved. (DS)

Presents a method which organizes concepts and relates different phenomena to a single model of ecology. Describes how this model is used to explain the overall significance of biological and ecological cycles and its usefulness in helping students to understand the various dangers to and remedies available for an ecosystem. (CS)

Described are animals that can filter their food out of the water. Various structures modified to strain plankton and small animals from water are detailed. The adaptive significance of these structures is discussed. (CW)

Discusses the value of setting-specific research for action research in social psychology. Discusses the following concepts: (1) local variation; (2) seeing the general in the specific; (3) connectedness as the fundamental law of ecology; and (4) the value of field stations for community research. (JS)

Discussed is an activity designed to teach small mammal ecology and the scientific method using fluorescent dyes and pigments. Procedures for analyzing home ranges and social organizations are described. A list of 16 references is included. (CW)

This paper includes a general account of the biology of the brine shrimp, instructions on how the organism may be cultured, the results of some experiments on the ecology and population biology of the species, and some suggestions for further studies. (Author/CW)

Presented is an exercise for high school students which illustrates the principle and practice of measuring energy flow through a community. Included are worksheets, instructions, a flow diagram, and a list of ecosystem parameters. (Author/CW)

Suggests activities for studying the variety of life forms found and the interaction of living things during a class trip to the beach. (WRM)

The term "deep map" is the invention of writer William Least Heat-Moon, whose extended essay "PrairyErth (a deep map)" has given definition to this form. Deep-map writing is marked by its intertextual, interdisciplinary, and multivocal nature. It is also self-consciously cartographic, presenting maps, following maps, and redrawing maps. Deep…

In the late 1990s the Singapore government embarked on a set of far-reaching strategies intended to develop the city-state into one of the major life science R&D and industrial clusters in Asia. Besides efforts to attract leading overseas life science companies to establish operations in Singapore, the government has developed new life science…

Appropriate for secondary school botany instruction, this study guide focuses on the important roles of plants in human lives. Following a rationale for learning the basic skills of a botanist, separate sections discuss the process sunlight undergoes during photosynthesis, the flow of energy in the food chain, alternative plant lifestyles, plant…
