Problems encountered in converting a card-oriented biological data information system to new computer equipment are discussed. Data formats, input-output procedures, search strategies, etc., are described. (5 references) (Author/SJ)

Argues that overexploitation of renewable biological resources to the point of extinction is possible under private (commercial) management. Public surveillance is necessary to prevent severe depletion of resources. An economic theory of a biological resource is developed, using the blue whale population as an example. (JR)

Discusses the mechanisms of genetic recombination with particular emphasis on the study of the fungus Sordaria brevicollis. The study of recombination is facilitated by the use of mutants of this fungus in which the color of the ascospores is affected. (JR)

Discusses the defense mechanisms and immune reaction found in invertebrates, and examines the wealth of related biological problems that need study and many of the leads that have recently been developed. (JR)

The relationship between the two concepts (evolution, religion) from an historical and social view is discussed. The concepts are seen to respond differently to the various needs of society, with considerable conflict between them in areas which involve the justification of religious beliefs. (Author/EB)

Describes results of efforts to seek effective ways of combining the knowledge and skill of different professions in alleviating environmental problems. An inter-society liaison committee on the environment was formed to implement the general philosophical goals of the conference. (EB)
