Elements of Marine Ecology
It is now sixteen years since the third edition of this student textbook was
published, and during this time advances in the field of marine biology have been
many and varied. Continuing demand for the book has therefore led to this
fourth, completely revised and updated edition. Developments in technology have
been particularly rapid, especially in the fields of diving, precision instruments,
satellite communications and computers, and these advances have greatly
improved and expanded our ability to explore the oceans and their marine life.
At the same time, the impact of man on the marine environment is ever increasing
and cannot be ignored in any study of marine ecology. Therefore the chapters on
‘Measuring and sampling’ and ‘Sea fisheries’ have been extensively revised, and
a new chapter on the ‘Human impact on the marine environment’ has been added.
The aim of the latter is to introduce the student to the various ways in which our
activities are changing the ecology of the oceans, with potentially far-reaching
effects. Additional material on coral reefs, hydrothermal vents, phenomena such
as ‘El Nino’ and ocean processes, including the important ‘microbial loop’ of the
food web, have been incorporated into existing chapters.
Although the book has been extensively revised, this edition retains its original
aim of presenting marine ecology as a coherent science and its scope derives from
the original, broad definition of ecology as the study of organisms in relation to
their surroundings. The text has been compiled as introductory reading for
students undertaking courses in marine biology. It provides information and ideas
over the general field of marine ecology with reading lists and references from
which additional material can be sought. With the busy student in mind, the text
has been re-arranged into clearly labelled and numbered sections. The field course
book list in the appendices has been extensively revised and updated as have the
references and student texts listed at the end of each chapter.
