Phytoplankton and Trophic Gradients - Proceedings of the 10th Workshop of the International Association of Phytoplankton... Phytoplankton and Trophic Gradients - Proceedings of the 10th Workshop of the International Association of Phytoplankton Taxonomy & Ecology (IAP), held in Granada, Spain, 21-29 June 1996 (Paperback, Softcover reprint of hardcover 1st ed. 1998)

These proceedings deal with the relationship between species composition of freshwater phytoplankton and the trophic gradient. Particular regard is paid to the composite question, what lives where and why? Overview papers report the state of the art and suggest that the trophic spectrum appears to be a probabilistic outcome of several dimensions of variability that impinge upon phytoplankton species selection. Studies on community structure span all latitudes from those of Antarctica to equatorial Brazil, and also include reports on light and nutrient gradients, pH and fish-stock effects on species composition. Seasonal and longterm phytoplankton dynamics in lakes of varying trophic status are also considered. Finally, studies on the taxonomy and autoecology of some groups (e.g. Volvocales, Chrysophytes and Euglenophytes) living at the extremes of the trophic spectrum contribute to our knowledge of this usually neglected phytoplankton. This is the first time that a book covers such a topic, and it will prove an excellent source of information to anyone working on phytoplankton ecology and ecological indicators. Limnologists in general, algologists and the technical staff at water authorities will all benefit by reading this book.

Biogeography of Freshwater Algae (Paperback, 1st ed. Softcover of orig. ed. 1997): Jorgen Kristiansen Biogeography of Freshwater Algae (Paperback, 1st ed. Softcover of orig. ed. 1997)
Jorgen Kristiansen
R4,551 Discovery Miles 45 510 Ships in 10 - 15 working days

This book is based on a workshop on biogeography of freshwater algae held during the Fifth International Phycological Congress in China 1994. A group of outstanding specialists covering widely different approaches to the subject have been brought together, and this collection of their contributions forms a unique volume: there is no other book on the subject. It thus fills an evident gap in the phycological literature, and will be of major interest to researchers and teachers within phycology, limnology, and evolutionary biology. However, it may also be useful in courses for advanced students.

Chrysophytes - Aspects and Problems (Paperback): Jorgen Kristiansen, Robert A Andersen Chrysophytes - Aspects and Problems (Paperback)
Jorgen Kristiansen, Robert A Andersen
R1,442 Discovery Miles 14 420 Ships in 10 - 15 working days

Originally published in 1986, this book presents an in-depth treatment of the biology of the chrysophytes. The papers collected here are a result of the First International Chrysophyte Symposium held at the University of North Dakota in 1953. The 'golden algae', a group of predominantly fresh water microorganisms, have distinctive features that present much information about their taxonomic classification, their place in evolution and their role in the environment. The ecological significance of the chrysophytes is evident from their abundance in acid bogs and lakes, a condition that has created a new group of investigators concerned with these unique algae and the changing environment. These are just some of the aspects of chrysophyte biology that are discussed here. This book provides a strong foundation towards understanding today's living forms of chrysophyte algae and sheds light on the probable aquatic ecosystems of the past.
