The carabid beetle (Notiophilus) preys readily on an easily-cultured collembolan in simple experimental conditions. Some features of this predator-prey system are outlined to emphasize its use in biology instruction. Experiments with another potential collembolan are described in the context of developing the method for more advanced studies.…

The principles of ecology are defined. Problems encountered in teaching ecology in schools are examined in order to establish reasons for the lack of good ecology teaching. Suggestions are made for overcoming these problems. Criteria for choosing suitable sites for ecology fieldwork are listed in an appendix. (Author/CS)

Discusses the current theories concerning the evolution of insect-plant relationships. Offers several experiments based on recent publications in this field, concerning relationships between herbivore number and plants' successional status, geographical range, geological history, and stage of growth, and also experiments on the chemical basis of…

Discusses advantages of using an estuarine environment as a study area for A-level students and reviews organizational considerations. Details and references regarding a variety of suitable techniques are provided along with examples of results obtained by students at Waltham Forest College. (Author/DC)

Presents a method for calculating age specific expectation of life for human populations by examining obituary entries in newspapers, tombstones, and parish records. Examples are given which illustrate large differences between the sexes, social classes, and dates at a given locality. (Author/CS)

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

Describes an approach to ecology teaching based on a workbook of structured integrated exercises and in-service courses for teachers. (Author/MA)

Discussed is the biotic indexing of water quality and its application to A-level field work with reference to the Trent Biotic Index and Chandler Score system. These indices are related to the classification of water quality used by the Department of the Environment. Interpretations and limitations of the indices are discussed. (Author/DS)

Discusses the Royal Society for the Protection of Birds (RSPB). Founded in 1889, it is Europe's largest voluntary conservation organization with some 965,000 members. One of the organization's main goals is environmental education in schools and colleges and the society's junior membership. Another main thrust is its reserves in England for…

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)

Two designs of undergraduate terrestrial ecology and behavior field courses are described and compared. These include using a variety of projects and using a single individual research project. The relative educational benefits of each are considered and the advantages of each type of course are discussed. (Author/CW)

Proposes domestic pests as ideal material for ecological studies to provide readily accessible and relatively simple communities. Describes the booklouse and a number of other suitable species. Suggests the use of the students' own homes as habitats to investigate and for use in teaching the principles of population dynamics. (RT)

Describes two working models of moths that can be used to test the eyespot function as an aversive property. Uses simple mechanical and electrical models as the "moths" and wild birds as the predators. Includes diagrams, methods, models, validation statements, and a discussion. (RT)

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)
