This volume results from a symposium entitled "Species and Ufe History Patterns: Geographic and Habitat Variation," held during the National Meeting of the Entomo logical Society of America in Denver, Colorado, USA in November, 1979. The stimu lus to assemble papers on this theme emerged from continuing discussions with col leagues concerning controversies in ecology and evolutionary biology, namely those associated with plant-herbivore interactions, life history theory, and the equilibrium status of communities. The study organisms used in this series of reports are all either herbivorous...

Traditionally, studies in ecological genetics have involved both field observations and laboratory genetic analyses. Comparisons and cor relations between these two kinds of data have provided valuable in formation on the genetic strategies behind the evolutionary adapta tions of species and their component local populations. Indeed, much of our current understanding of the dynamics of evolutionary pro cesses has come fro syntheses of ecological and genetic information. Since the recent discovery of abundant markers in the form of protein polymorphisms, scientific interest in the connections...

This conference represents the first time in my life when I felt it was a misfor- tune, rather than a major cause of my happiness, that I do conservation work in New Guinea. Yes, it is true that New Guinea is a fascinating microcosm, it has fascinating birds and people, and it has large expanses of undisturbed rainforest. In the course of my work there, helping the Indonesian government and World Wildlife Fund set up a comprehensive national park system, I have been able to study animals in areas without any human population. But New Guinea has one serious drawback: it has no primates, except...

The past two decades have seen an extraordinary growth of interest in the auditory mechanisms of a wide range of vertebrates and invertebrates. Investigations have ranged from auditory mechanisms in relatively simple animals where just a few cells are em ployed for detection of sound, to the highly complex detection and processing systems of man and the other mammals. Of particular significance to us has been the growing interest in general principles of vertebrate auditory system organization, as opposed to a specific and limited concern for the mammalian or even human systems. Some of the...

This volume is an outgrowth of a Symposium entitled "Evolution of Escape in Space and Time" held at the XV International Congress of Entomology in Washington, D. C., USA in August, 1976. The choice of topic was prompted by recent advances in evolutionary ecology and the apparent suitability of insect migration and dia pause as appropriate material for evolutionary studies. In the event, that choice seems amply justified as I hope a perusal of these papers will show. These Sympos ium papers hardly cover the topic of the evolution of escape mechanisms exhaustively, and I am sure everyone will...

This volume is the result of a symposium entitled "Variation in Life Histories: Genetics and Evolutionary Processes" sponsored by the Program in Evolutionary Ecology and Behavior of the University of Iowa and held in Iowa City on October 13 and 14, 1980. Prompted by a recent upsurge of interest in the evolution of life histories, we chose this topic because of the obvious association between life history traits and Darwinian fit ness. If such an association were to be fruitfully investigated, it would require the closer cooperation of population and evolutionary ecologists and quantitative...

The VIIIth International Congress of the International Primatological Society was held from 7 through 12 July 1980 in Florence, Italy, under the auspices of the host institution, the Istituto di Antropologia of the University of Florence. More than 300 papers and abstracts were pre- sented either at the main Congress or in 14 pre-Congress symposia the week earlier (so scheduled to avoid conflicting with either the main invited lectures or the contributed paper sessions). The texts of these main lectures, plus reports from the organizers on results of the pre-Congress symposia, form this...

This volume is based on a Symposium entitled "Insect Flight: Dispersal and Migration" held at the XVllth International Congress of Entomology in Hamburg, Germany in August, 1984. An earlier similar Symposium was held at the XVthInternational Congressof Entomologyin 1976 in Washington DC, USA ("Evolution ofInsect Migration and Diapause" edited by Hugh Dingle, Springer-Verlag, 1978). It is, therefore, appropriate that the present Sym- posium was held 8 years later in view ofthe intensified interest and develop- ments in this field, particularly in the areas ofevolution, genetics, endocrine/...

The recent symposium and the appearance of this new book on Drugs Affecting Lipid Metabolism take place at a very unusual time for the development of this area. After the publication and wide acceptance of the results of the cholestyramine study by the Lipid Clinics in the USA, showing for the first time a direct association between drug induced reduction of plasma levels of total and LDL cholesterol and coronary heart disease in a high risk population, an unparalleled interest in drugs and other procedures able to control plasma cholesterol levels has been activated. Two other significant...
