Biological Properties is a collection of papers that deals with the biological properties of iron-sulfur proteins. One paper reviews the role of electron paramagnetic resonance in forwarding knowledge about iron-sulfur proteins. Iron-sulfur proteins are iron proteins where sulfur is a ligand of the iron, of which the iron is not simultaneously held by a stronger ligand such as porphyrin. Another paper discusses the role of bacterial ferredoxins in coupled oxidation-reduction reactions, the role of hydrogenase in oxidation-reduction, as well as the bacterial iron-sulfur proteins, such as azoferredoxin and molybdoferredoxin. Abiological models of nitrogenase involve molybdenum and iron with sulfur ligands; these abiological systems can be the first models that show the biological activity of iron-sulfur enzymes which these systems try to copy. One paper investigates the role of iron-sulfur proteins in photosynthesis, particularly the photoreduction of ferrodoxin, the mechanism of NADPH formation, and the possible role of ferrodoxin in cyclic photophosphorylation. This collection is suitable for bio-chemists, cellular biologists, micro-biologists, and scientists involved in research in the biological disciplines.

Proceedings of a conference on Tropical Forests: Botanical Dynamics, Speciation and Diversity held at the University of Aarhus, Denmark, August 8•ba10, 1988.The increasing rate of destruction of the world's tropical forests gives grave cause for concern on several counts. In conservative terms, species are being lost at an incredible rate, many before they have even been described. In scientific terms, habitats, communities, and unique systems are lost before they can be studied and used to broaden our understanding of ecological processes in general.The meeting on which this book is based aimed to address two basic needs: to describe some of the marvellous biological treasures of tropical forests and to learn what they can tellus about processes in ecology, and to alert us all once again to the disaster which is overtaking this rich and varied environment.

This book contains the results and conclusions of extensive research on the causes and effects of acidification of forests/forest soils and heathland in the Netherlands. In 1985 the Dutch Priority Programme on Acidification was started in order to give a more concrete form to the increasing interest of policy-makers in the effects of air pollution on ecosystems in particular.In the last three years, the research has focused on obtaining a more accurate estimate of the emission of ammonia on the deposition of SOx, NOy and NHx, and also on quantifying effects on forest and heathland ecosystems. This quantification of effects included experimental work model analyses, and derivation of critical loads and levels for forest and heathland ecosystems. Furthermore, scenario analyses were made with the Dutch Acidification Systems Model (DAS) in order to evaluate the effectiveness of policy measures.The research itself, which formed the basis for this book, has been described in the reports on individual projects. A summary of the scientific results and conclusions is given in thematic reports (added as annex). An independent Review Team has provided a critical assessment of the research carried out since 1988. The Review Report has been incorporated as annex.
