The bibl iography includes papers in all fields of photosynthesis research - from studies of model biochemical and biophysical systems of the photosynthetic mecha~ nism to primary production studied by the so-cal led growth analysis. In addition to papers devoted entirely to photosynthesis, papers on other topics are included if they contain data on photosynthetic activity, photorespiration, chloroplast structure, chlorophyll and carotenoid synthesis and destruction, etc., or if they contain valuable methodological information (measurement of selected environmental factors, leaf area, etc.). In many branches it has been difficult to define the I i mits of interest for photosynthesis researchers. This problem has arisen e. g. in to pics deal ing with the tranfer of gases, where - in addition to the papers on carbon dioxide transfer - some papers on water vapour transfer are included, these being of general appl ication or bringing new approaches. On the other hand, many papers deal ing with the anatomy and physiology of stomata have been omitted, if the aspect of carbon dioxide or water vapour exchange has not been discussed. This volume contains references to papers publ ished in the year 1982, and simi larly to preceding volumes also addenda including references publ ished in the preceding period (i. e. 1966 to 1981). The numbers of the additional references are labelled with an asterisk (*) in the I ist of references.

Vols. for 1911-13 contain the Proceedings of the Helminothological Society of Washington, ISSN 0018-0120, 1st-15th meeting.

It is generally accepted that photosynthesis, whereby solar is transformed into geobiochemical energy, is one of the most important processes in the bio sphere. When we realize that the human population, most of which is starving, wi I I double in 20-30 years, and that photosynthesis is in practice the only source (direct or indirect) of food not only for men, but for al I I iving beings, its im portance becomes even plainer. This fact was recognized from the outset of the International Biological Programme, when photosynthesis was selected as one of the principal problems to be concentrated on. The significance of the IBP in initiating a broader-based ap proach and worldwide collaboration need not be emphasized here; it is merely ne cessary to consider the rapid increase in the number of papers on photosynthesis since its inception. It is of fundamental importance for scientists working on photosynthesis to get information on what has been done in recent years in this discipl ine. Thus as complete as possible a bibl iography is badly needed. The complexity of this pro blem requires also that the progress of ecology, chemistry and physics, as far as they concern photosynthesis, be fol lowed. Such a bib I iography, covering at least the last ten years, wi I I be indispensable for final synthesis of the results of the IBP photosynthetic programme.
