In the spring of 1969 a small meeting was convened at the CSIRO Riverina Laboratory, Deniliquin, New South Wales, to discuss the biology of the genus Atriplex, a group of plants considered by those who attended to be of profound importance both in relation to range management in the region and as a tool in physiological research.

The wealth of the natural sciences no longer consists in the abundance of facts, but in the way they are linked together.

When we wrote this book it was, admittedly, flrst of all for the sake of our own enjoyment and enlightenment.

Animals are important components of any ecosystem and it is impossible to describe structure and funCtioning of the Fennoscandian tundra ecosystems without including this part of the system.

No other disjunct pieces of land present such striking similarities as the widely sepa- 1 rated regions with a mediterranean type of climate, that is, the territories fringing the Mediterranean Sea, California, Central Chile and the southernmost strips of South Mrica and Australia.

Throughout the world natural forest ecosystems have been, and are being massively disrupted or destroyed.

Plans for an International Symposium on the Early Life History of Fish were first discussed in 1967 at the F.

The study of thermoregulation in endotherms has contributed much to the emergence of the concept of control theory in biology.

The Advanced Series in Agricultural Sciences is designed to ftll a long-felt need for advanced educational and technological books in the agricultural sciences.

It is two years since a general meeting of the Gesellschaft fur Biologische Chemie first requested us to organize the 21 st Mosbach Colloquium on mammalian reproduction, and one year since we received final authorization to do so.

Production of food to meet the demands of an ever-increasing human population in the world is the major task and challenge to agriculture today.

'frees contribute a major part of fuel, fodder and fruit, and are an im- of bioenergy.

Haploid plants have the gametophytic number of chromosomes.

Hazard assessment of a compound (xenobiotic) discharged to the aquatic environment requires data on both exposure and effects to various components of the ecosystem.

During the last decade, forest decline has become increasingly apparent.

The Second Autumn Course on Mathematical Ecology was held at the Intern- ational Centre for Theoretical Physics in Trieste, Italy in November and December of 1986.

Atmospheric carbon dioxide concentration has increased globally from about 280 ppm before the Industrial Revolution (Pearman 1988) to about 353 ppm in 1990.

The economic costs of frosts in agriculture and horticulture in many parts of the world can be very significant.

Comprising about one hundred plates this atlas documents anddescribes the processes concerning the sexual reproductionin higher plants.

The biota of the earth is being altered at an unprecedented rate.

stable isotope ratios act as naturally-occurring tracers for organic matter, making possible, under certain conditions, the quantification of coastal-offshore exchanges.

The pulse of life with the seasons is a classic theme of biology, equally cap- turing every man's curiosity about early and late milestones of every year's cycle and the critical physiologist's inquiry into life's subtle signals and responses.
