Allelochemicals play a great role in managed and natural ecosystems. Apart from plant growth, allelochemicals also may influence nutrient dynamics, mycorrhizae, soil chemical characteristics, and microbial ecology. Synergistic action of various factors may better explain plant growth and distribution in natural systems. The book emphasizes the role of allelochemicals in shaping the structure of plant communities in a broader ecological perspective. The book addresses the following questions: (1) How do allelochemicals influence different components of the ecosystem in terms of shaping community structure? (2) Why is it difficult to demonstrate interference by allelochemicals (i.e., allelopathy) in a natural system in its entirety? Despite a large amount of existing literature on allelopathy, why are ecologists still skeptical about the existence of allelopathy in nature? (3) Why are there only scarce data on aquatic ecosystems? (4) What role do allelochemicals play in microbial ecology?.....

This book contains the results of a Symposium on the physiological ecology of plants of the lowland wet tropics held in Mexico in June 1983 organized by the Instituto de Biologla of the National University of M"exico (U. N . A. M. ), and sponsored by UNAM, CONACYT, NSF and UNESCO (CIET). A workshop portion of the Symposium was held at the tropical research station at Los Tuxtlas, Veracruz. This Symposium originated in response to the increasing interest in the physiological ecology of tropical plants, because of the potential. of this field to provide a basic understanding of functioning of tropical plant communities. The study of physiological ecology of tropical plants has been delayed in some cases by the lack of conceptual framework, but also by the absence of appropriate instrumentation and techniques with which to conduct precise measurements under high temperature, high humidity field conditions. Hypotheses and concepts of the physiological ecology of tropical plants have been based mainly on observational data and the analysis of growth forms and leaf anatomf. The early work of A. F. W. Schimper and o. Stocker in Asia, and the extensive surveys made by H. Walter on the osmotic potentials of plants in the tropics and subtropics, constituted, until relatively recently, the only available information on the water and carbon relations of tropical plants.

Evolutionary biologists have produced a solid body of evidence to explain patterns of diversification, both within and among species. Recent textbooks are weighted towards studies of animals, which is surprising given that plants are ideally suited for answering evolutionary questions. Plants do not stand up and walk away and they can easily be cloned, transplanted or potted for experiments. This book aims to set the record straight by placing the wealth of data that have been collected on plants into the unifying framework of game theory. This allows a test of the theory of natural selection in some cases, while in other cases highlighting the need for additional data collection and theoretical development. It is the authors' hope that many students will take on this challenge and help the study of the evolutionary ecology of plants to develop as a mature, predictive science.

Plant secondary metabolites (PSMs) such as terpenes and phenolic compounds are known to have numerous ecological roles, notably in defence against herbivores, pathogens and abiotic stresses and in interactions with competitors and mutualists. This book reviews recent developments in the field to provide a synthesis of the function, ecology and evolution of PSMs, revealing our increased awareness of their integrative role in connecting natural systems. It emphasises the multiple roles of secondary metabolites in mediating the interactions between organisms and their environment at a range of scales of ecological organisation, demonstrating how genes encoding for PSM biosynthetic enzymes can have effects from the cellular scale within individual plants all the way to global environmental processes. A range of recent methodological advances, including molecular, transgenic and metabolomic techniques, are illustrated and promising directions for future studies are identified, making this a valuable reference for researchers and graduate students in the field.

Plant ecology is a branch of ecology, which is concerned with the study of the abundance and distribution of plants, the effect of environmental factors and the interactions between plants and other organisms. The plant kingdom ranges in complexity from the single-celled algae to large canopy forming trees. Plant communities are distributed into biomes depending on the dominant plant species present. Some of the important vegetation types are tundra, terrestrial wetlands, temperate grasslands, tropical forests, tropical savannas, etc. The predominant biological interactions occurring in plant communities are competition for resources, mutualism and herbivory. Depending on the level of organization, plant ecology can be divided into plant ecophysiology, community ecology, ecosystem ecology and biosphere ecology, among others. This book studies, analyzes and upholds the pillars of plant ecology and its utmost significance in modern times. It includes some of the vital pieces of work being conducted across the world, on the ecology and diversity of plants. The extensive content herein provides the readers with a thorough understanding of the subject.
