Suggests an approach and methodology for analyzing field and laboratory populations. Describes an experiment using mustard to show how competition and inequality can be assessed. Discusses the variables responsible for determining the abundance of organisms. (CW)

Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)

Presents experiments using wild birds as predators and pastry as prey and colored stones as background to demonstrate natural selection. Describes the exercise as an exercise in simulating natural selection. (Author/CW)

Presented are several ideas for projects involving ladybird beetles. Discussed is background information about the insects; and projects involving life histories, intra-specific variation, taxonomy, genetics, behavior, ecology, habitat surveys, population biology, and overwintering biology. Lists 12 references. (CW)

Describes results and experiences of four field-course experiments designed to explore the relationships between animals and their physical environment. Reports on the response of animals to flow rate of water, relationship between size and rate of locomotion, and mathematical and physical techniques used to study how animals live. (RT)

Lichenometry is described for use in the study of biology and physical weathering. Discussed are lichens in general and an outline for studying growth and ecology. A problem solving format is used. (CW)

Provided is a brief description of the biology and taxonomy of British ants. Suggested are a range of exercises which could be used for class or project work in secondary biology classes. Illustrates many ecological, behavioral and physiological points regarding the species of ants found in Great Britain. (Author/CW)
