Much effort has been devoted to developing theories to explain the
wide variation we observe in reproductive allocation among
environments. Reproductive Allocation in Plants describes why
plants differ in the proportion of their resources that they
allocate to reproduction and looks into the various theories. This
book examines the ecological and evolutionary explanations for
variation in plant reproductive allocation from the perspective of
the underlying physiological mechanisms controlling reproduction
and growth. An international team of leading experts have prepared
chapters summarizing the current state of the field and offering
their views on the factors determining reproductive allocation in
plants. This will be a valuable resource for senior undergraduate
students, graduate students and researchers in ecology, plant
ecophysiology, and population biology.
Forces of nature and human intervention lead to innumerable local, regional and sometimes global changes in plant community patterns. Regardless of the causes and the intensity of change, ecosystems are often naturally able to recover most of their attributes through natural succession. In this thoughtful and provocative new book, Fakhri Bazzaz integrates and synthesizes information on how disturbance changes the environment, how species function, coexist, and share or compete for resources in populations and communities, and how species replace each other over successional time. It illustrates how a diverse array of plant species have been used to examine fundamental questions in plant ecology by integrating physiological, population and community ecology. Graduate students and research workers in plant ecology, global change, conservation and restoration will find the perspective and analysis offered by this book an exciting contribution to the development of our understanding of plant successional change.

The earth's landscapes are being increasingly impacted by the activities of man. Unfortunately, we do not have a full understanding of the consequences of these disturbances on the earth's productive capacity. This problem was addressed by a group of French and U.S. ecologists who are specialists at levels of integration extending from genetics to the biosphere at a meeting at Stanford, California, sponsored by the National Science Foundation and the Centre National de la Recherche Scientifique. With a few important exceptions it was found at this meeting that most man-induced disturbances of ecosystems can be viewed as large scale patterns of disturbances that have occurred, generally on a small scale, in ecosystems through evolutionary time. Man has induced dramatic large-scale changes in the environment which must be viewed at the biosphere level. Acid deposition and CO increase are two 2 examples of the consequences of man's increased utilization of fossil fuels. It is a matter of considerable concern that we cannot yet fully predict the ecological consequences of these environmental changes. Such problems must be addressed at the international level, yet substantive mechanisms to do this are not available."
