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.
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.

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.
