影響因子With the continuous increase in human population and its constant demands on the aquatic environment, there has been a compounding of the interrelationships between algae and man. These relatively simple green plants not too long ago were often considered as merely biological curiosities. Within the past twenty-five years, with advances in technology and the increased eutrophication of lakes and streams, the interplay between algae and man has become more complex and more im- portant. Problems of taste, odor, toxicity, or obnoxious growth caused by algae are unfortunately quite familiar to the water supplier and to the public health worker. Algae have met their role in the space age as a possible source for food or as a gas ex- changer. In order to explore any of these practical problems, it is essential to have adequate, basic knowledge of algal taxonomy, physiology, cytogenetics and ecology. This book is the outgrowth of a North Atlantic Treaty Organi- zation Advanced Study Institute in which authorities in both the applied and basic fields of phycology, as well as in cognate disci- plines, met and discussed various topics related to algae. It is of significance to note that this

Environmental Conditions and the Pattern of Metabolism in Algae, to which it is exposed. This is sometimes obvious to the unaided eye—as, for example, when a green, actively growing culture of . is compared with a nitrogen-deficient one in which the cells have accumulated carotenoids and lipoids— and impressive evidence of it is given by many sets of analytical

Micronutrient Requirements for Green Plants, Especially Algae,t. Table I gives the list of these nutrient elements and indicates whether they are macronutrients or micronutrients. Some of the elements vary depending upon whether they are utilized by higher plants or by green or blue-green algae. Plants require mineral elements for various functions. The macron

Some Problems Remaining in Algae Culturing,oint out certain modern developments which either have not received a satisfactory answer, or are still creating some confusion. Among such problems are: the estimation of growth or yield; different methods of purification to obtain bacteria- free cultures; the influence and the size of the inoculum

The Ecology of Plankton Algae,r understanding of the term, because he has heard it so often in discussions of good water, of space travel, and of toxic or nuisance effects. The biologist recognizes the much wider coverage of the word than the “microscopic green plants” of the layman; he too is cognizant of the above connotations

Principles of Primary Productivity: Photosynthesis Under Completely Natural Conditions,ically all other processes occurring in nature. The variations are such that samples collected a few moments or a few meters apart will routinely differ by 20% and not at all unroutinely by 50% or more. The most important consequence of this variation is that an individual sample is poorly represent

Algae in Water Supplies of the United States,round sources after it is exposed to sunlight. Surface waters invariably are habitats for the growth of algae. The amount of growth may be small or very extensive depending upon the concentration of nutrients, turbidity, temperature, and length of exposure to light.
