Describes the coordinated study of European grasshoppers as living specimens in the field and as permanent laboratory preparations for introducing taxonomic principles. Provides details for the preparation of specimens and sample instructions provided to students. Part I of a three-part series. (AL)

Discusses the relationships of individual, population and ecosystem level approaches to ecology. Outlines how these approaches can be used in introductory college ecology courses. Emphasizes the importance of laboratory and field work and makes explicit suggestions. Outlines course sequences in the undergraduate systems ecology program at San…

Describes techniques for studying historic changes in climate by analysis of pollen preserved in peat bogs. Illustrates the methodology and data analysis techniques by reference to results from English research. (AL)

Describes the use of capture-recapture techniques to estimate the population of taxis in Liverpool and demonstrates the points of similarity to animal population estimation. Considers advantages of studying taxis rather than organisms in introductory studies of the techniques. (AL)

Short articles describing a model of protein synthesis, a simple constant temperature incubator, techniques for determining the age structure of populations from qualitative characters, an experimental demonstration of proteolytic enzyme action, and apparatus for demonstrating hydrotrophic response of roots and for measuring photosynthetic rate of…

Describes procedures used to provide trainee teachers with experience in conducting ecological field studies, including preliminary classroom instruction, residential field experience, follow-up classroom work, and testing and evaluation. Summarizes opinions of students and trainee teachers on the worth of the experience. (AL)

Background information on pond habitats and on the food pyramid is provided. Two learning activities for studying a pond are suggested. (DT)

Discusses the advantages and disadvantages of selecting coastal sand dunes as the location for field ecology studies. Presents a descriptive zonal model for seaboard sand dune plant communities, suggestions concerning possible observations and activities relevant to interpreting phenomena associated with these forms of vegetation, and additional…

Gives description of sampling techniques used by a science class to gather water pollution data from a park pond. (CP)

Suggests methods of teaching plant identification and taxonomic theory using keys, statistical analyses, and biometrics. Population variation, genotype- environment interaction and experimental taxonomy are used in laboratory and field. (AL)
