Foreword
This special edition of Hydrobiologia follows an established precedent for the presentation of selected papers read
and discussed by participants at Workshop meetings of the International Association of Phytoplankton Taxonomy
and Ecology (lAP). Much as its title implies, the Association exists to promote and foster the scientific study of
(mainly) freshwater plankton, especially among its younger practitioners. Principally through the discussion of
common problems of identification and taxonomy, of methodology and of ecological interpretation, the lAP has
established a tradition of themed workshops with tangible, practical contributions to particular issues of general
concern among the participants. Its 1991 Workshop, for instance, tackled the relevance of the Intermediate Disturb
ance Hypothesis to plankton dynamics: this became a subject of debate well outside our group and the publication
of the proceedings, in Hydrobiologia 249 (reprinted in Kluwer's Developments in Hydrobiology series, No. 81),
is still in considerable demand. The 1993 workshop considered the impacts of turbidity and aggressive turbulence
as selective factors in rivers and shallow lakes, and the published papers (in Hydrobiologia 289; Developments
in Hydrobiology No. 100) have also proved to be of general interest. The subject of the tenth lAP Workshop,
held in 1996 in Granada, Spain, looked at the role of the trophic state of a water body as a species-selective
mechanism. The many contributions made a further fascinating volume (Hydrobiologia 3691370; Developments in
Hydrobiology No. 118) but it will confirm that the participants were unable to reach a consensus about the main
mechanistic explanation for the familiar and distinctive patterns of phytoplankton composition in relation to trophic
state. The theme for the 1998 meeting was agreed in Granada: "The Trophic Spectrum Revisited".
Papers read or posted at the lAP's Eleventh Workshop, which was held at Preston Montford Field Cente, near
Shrewsbury, England, from 15-23 August, 1998, make up the present volume. The submissions complied well
with the agreed theme. Contributors were invited to give special attention to the fact that distinctive assemblages
of phytoplankton species are closely associated with particular categories of water body, often on the basis of their
trophic states. The intent was to improve the acuity of answers to the question, "What is it about the trophic state of
a water body which selects for the kinds of species that become characteristically abundant'?" The role of optimal
resource ratios (to include light income) and the alternative bias of inoculum effect were trailed as candidates for
definitive exploration.
Recognising the poverty of our understanding of the processes of community assembly, however, new ideas
were broadly canvassed too. Most of all, contributors were invited to consider the distributions of named organisms
rather than the totality of species found particular "our-lake" sites, with particular attention being directed towards
the extremes of distributional ranges or to occurrences which are counterintuitive. Here, the intent was to determine
the extent to which taxa recognise the nutrient availability in the waters of which they are said to be indicative.
Participants were also invited to "design a plankton". This was an exercise intended to explore attitudes and
concepts about phytoplankton selection: details of undisclosed habitats and their limnological features and en
vironmental histories were offered to invitees who were asked "to report" their anticipation of the fluctuations
in abundance and species composition of the phytoplankton as if they had been real events. Few of those who
accepted the challenge actually did the exercise in advance but, once at the Workshop, all the participants tackled
it as group activity. The outcome is discussed in Reynolds (this volume).
This is just one of fourteen papers that make up this volume. The majority of these are presented as case studies,
concerning the phytoplankton of particular lakes or series of lakes. To greater or lesser extents, the contributions
move away from being purely descriptive: several of the authors have taken the broader view and related their
observations to the selective processes and community structures recognised elsewhere. These lead to the papers
recommending wider approaches and alternative methodologies for viewing and classifying information about the
structure of planktonic communities. Finally, an editorial is presented which assesses the progress and scientific
contribution that the workshop may have made to our understanding of phytoplankton selection in the context of
the trophic states of lakes.

We would like to this opportunity to thank the Director and Staff of the Preston Montford Field Centre for
hosting our visit, for providing such excellent food and accommodation and for arranging the one week of reason
able weather in the otherwise wet (even by normal British standards) summer of 1998. Sarah Reynolds provided
magnificent help as Workshop secretary and her contribution to its smooth running was gratefully acknowledged
by all the particpants.
In differing ways and to differing extents, all the Workshop participants have, at some stage in their academic
development, been influenced by the ideas and writings of Dr lW.O. Lund, F.R.S. Indeed, many of the issues that
have been discussed were first raised and explored by him during a career covering the last sixty-five years. The
Eleventh Workshop of the lAP was convened sufficiently close to John's eighty-fifth birthday for it to have been
proposed and unanimously agreed by the participants that this volume should be dedicated to John, as a token of
the affection and respect in which his inspiration and insights are held throughout the world.
