Book Description
A wide variety of plants, ranging in size from forest floor herbs to giant canopy trees, rely on animals to disperse their seeds. Typical values of the proportion of tropical vascular plants that produce fleshy fruits and have animal-dispersed seeds range from 50-90%, depending on habitat. In this section, the authors discuss this mutualism from the plant's perspective. Herrera begins by challenging the notion that plant traits traditionally interpreted as being the product of fruit-frugivore coevolution really are the outcome of a response-counter-response kind of evolutionary process. He uses examples of congeneric plants living in very different biotic and abiotic environments and whose fossilizable characteristics have not changed over long periods of time to argue that there exists little or no basis for assuming that gradualistic change and environmental tracking characterizes the interactions between plants and their vertebrate seed dispersers. A common theme that runs through the papers by Herrera, Denslow et at. , and Stiles and White is the importance of the 'fruiting environment' (i. e. the spatial relationships of conspecific and non-conspecific fruiting plants) on rates of fruit removal and patterns of seed rain. Herrera and Denslow et at. point out that this environment is largely outside the control of individual plant species and, as a result, closely coevolved interactions between vertebrates and plants are unlikely to evolve.

Book Description
Ants are probably the most dominant insect family on earth, and flowering plants have been the dominant plant group on land for more than 100 million years. In recent decades, human activities have degraded natural environments with unparalleled speed and scale, making it increasingly apparent that interspecific interactions vary not only under different ecological conditions and across habitats, but also according to anthropogenic global change. This is the first volume entirely devoted to the anthropogenic effects on the interactions between these two major components of terrestrial ecosystems. A first-rate team of contributors report their research from a variety of temperate and tropical ecosystems worldwide, including South, Central and North America, Africa, Japan, Polynesia, Indonesia and Australia. It provides an in-depth summary of the current understanding for researchers already acquainted with insect-plant interactions, yet is written at a level to offer a window into the ecology of ant-plant interactions for the mostly uninitiated international scientific community.

Book Description
Any scientific discipline needs a theoretical framework to guide its development and to sharpen the questions its researchers pursue. In biology, evolution is the grand theoretical framework, and an his torical perspective is necessary to understand present-day biological conditions. In its formative years, the modern study of the fruit-frugivore mutualism was guided by the 'specialist-generalist' paradigm developed by D. Snow, D. McKey, and H. Howe. Howe reviews the current status of this evolution ary paradigm and points out that it has been dismissed by many workers before being adequately tested. This is because ecologists working with the tropical plants and frugivorous birds for which the paradigm was originally developed rarely measure the seed dispersal effectiveness of different disperser species. He indicates that this paradigm still has heuristic value and suggests that several additional ecological paradigms, including the concept ofkeystone species ofplants and frugivores and the role that frugivores play in density-dependent mortality in tropical trees, are worth studying. The concept of seed dispersal quality has been central to discussions of fruit-frugivore coevolution. Schupp thoroughly reviews data bearing on this concept, constructs a hierarchical framework for viewing disperser effectiveness, and points out that disperser effectiveness depends on both the quantity and quality of seed dispersal. Effectiveness, in turn, affects both evolutionary and ecological relationships between dispersers and their food plants.

Book Description
The present book is divided into several parts. An introductory chapter serves to make the reader aware of the diversity of the subject of habitat selection in birds. Many if the various aspects of habitat selection introduced in the first chapter are developed in subsequent chapters, and thus it serves to some extent as an overview of the subject and as a "lead-in" to subsequent work.

Book Description
To understand how tropical ecosystems work we need to appreciate how the organisms within them interact with each other. This volume, first published in 2005, synthesises the state of knowledge in this area, providing reviews or case studies from both Old and New World tropics and dealing with taxa at all trophic levels.
