Preface
Diversity of plant form and life history and their distribution onto different habitats suggest
that plant functions should underlie this diversity, providing tools to successfully and differ-
entially thrive in every habitat. The knowledge of these functions is then the key to under-
stand community and ecosystem structure and functioning, something that attracted the
interest and effort of many plant ecologists trying to establish patterns of adaptive special-
ization in plants.
This volume on Functional Plant Ecology is an updated version of a successful first edition
in which we tried to put together chapters from all areas of plant ecology to provide readers
the broadest view of functional approaches to plant ecology. Our aim was to gather original
reviews with an attractive presentation, giving a comprehensive overview of the topic with a
historical perspective when needed. The book is intended for a broad audience, from plant
ecologists to students, with characteristics of both a textbook and an essay book. We were not
interested in presentation of new experimental data, novel theoretical interpretations, or
hypotheses, but rather asked the authors to provide easy-to-read, up-to-date, and suggestive
introductions to each topic.
Deciding the book composition was not an easy task, as many attractive, substantial
topics emerged at first glimpse. Finally, only a short number made their way into the book,
and we are aware that many important questions have been left out, but practical and
technical reasons limited the extent of the volume. The book follows a bottom-up approach,
from the more specific, detailed studies focusing on plant organs to the broadest ecosystem
approaches, each gathering chapters on the most outstanding aspects.
The history, aims, and potentials of functional approaches are established in the first
chapter, which also sets the limits of functional plant ecology, a science centered in the study
of whole plants and that attempts to predict responses in plant functioning caused by envir-
onmental clues, emphasizing plant influence on ecosystem functions, services, and products,
and aiming to extract patterns and functional laws from comparative analyses. The search for
these patterns is likely to be most effective if driven by specific hypotheses tested on the basis of
comparative analyses at the broadest possible scale. Functional laws thus developed may hold
predictive power irrespective of whether they represent direct cause–effect relationships. Yet,
the nested nature of the control of functional responses implies uncertainties when scaling
functional laws, either toward lower or higher levels of organization.
We would like to express our sincere thanks to the authors who contributed to this
volume for their efforts in updating their chapters and for meeting the deadlines over already
busy timetables. Finally, we want to thank John Sulzycki for his support throughout and Pat
Roberson for her help and patience. All of them made possible and greatly improved the
quality of this work.
