Download Positive Interactions and Interdependence in Plant Communities Book in PDF, Epub and Kindle
This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.

Download Plant Strategies and the Dynamics and Structure of Plant Communities Book in PDF, Epub and Kindle
In this new approach to understanding the dynamics occurring among plant populations at the community level, Tilman sets forth an exciting hypothesis to aid in explaining the factors operative in vegetation change. He emphasizes nutrient allocation, especially nitrogen and light, as a critical factor in addition to others in accounting for what is referred to as "succession" by most ecologists. Tilman initially presents some basic concepts--plant competition, resource allocation, and succession--followed by his extensive old field experiments on the Minnesota sand plain. These add support to his hypothesis concerning the role of nutrient allocation as a factor involved in vegetation change. Illustrations, including tables and figures, greatly enhance the text. A most readable book, and students of vegetation science will find it a welcome addition to their libraries. It also should find its way to all academic libraries since it is aimed primarily at professional plant ecologists. W.A. Niering Connecticut College--Choice Reviews.

Download Complex Population Dynamics Book in PDF, Epub and Kindle
This collection of review articles is devoted to the modeling of ecological, epidemiological and evolutionary systems. Theoretical mathematical models are perhaps one of the most powerful approaches available for increasing our understanding of the complex population dynamics in these natural systems. Exciting new techniques are currently being developed to meet this challenge, such as generalized or structural modeling, adaptive dynamics or multiplicative processes. Many of these new techniques stem from the field of nonlinear dynamics and chaos theory, where even the simplest mathematical rule can generate a rich variety of dynamical behaviors that bear a strong analogy to biological populations.

Download Interactions and Interdependence in Plant Communities Book in PDF, Epub and Kindle
The collection of plant species which are present in a particular geographical area, and which forms a relatively uniform patch that can be differentiated from neighboring patches of different vegetation types, is known as a plant community. The study of these communities of plants is integral towards developing an understanding of the impact of dispersal, response to disturbance and tolerance to environmental conditions in different varieties of plant species. Interactions and interdependence in plant communities involve the study of the influence of facilitation and positive interactions among species in plant communities. It includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions. This book includes some of the vital pieces of work being conducted across the world, on various topics related to interactions and interdependence in plant communities. It attempts to assist those with a goal of delving into the field of botany. This book is a resource guide for experts as well as students.

Download The Fungal Community Book in PDF, Epub and Kindle
The Fungal Community: Its Organization and Role in the Ecosystem, Third Edition addresses many of the questions related to the observations, characterizations, and functional attributes of fungal assemblages and their interaction with the environment and other organisms. This edition promotes awareness of the functional methods of classification over taxonomic methods, and approaches the concept of fungal communities from an ecological perspective, rather than from a fungicentric view. It has expanded to examine issues of global and local biodiversity, the problems associated with exotic species, and the debate concerning diversity and function. The third edition also focuses on current ecological discussions - diversity and function, scaling issues, disturbance, and invasive species - from a fungal perspective. In order to address these concepts, the book examines the appropriate techniques to identify fungi, calculate their abundance, determine their associations among themselves and other organisms, and measure their individual and community function. This book explains attempts to scale these measures from the microscopic cell level through local, landscape, and ecosystem levels. The totality of the ideas, methods, and results presented by the contributing authors points to the future direction of mycology.

Download Model Systems to Study the Excretory Function of Higher Plants Book in PDF, Epub and Kindle
The secretory activity of plants is a manifestation of the fundamental property of all living organisms: the ability to exchange substances and energy with the environment. This book summarizes today’s knowledge of all such secretory activities of higher plants. It equally considers the cellular aspects, intratissular and external secretion, gas excretion and the excretion of substances under extreme conditions as well as the biological effects of plant excreta. The first edition of the book was published in Russian in Moscow in 1989 (Nauka Publishing House), then the English larger variant – in Heidelberg-Berlin 1993 (Springer-Verlag).

Download Mycorrhizal Networks Book in PDF, Epub and Kindle
The last 25 years have seen significant advances in our understanding of the mycorrhizal fungi that colonize most of the world’s plants, and the mycorrhizal networks that form and extend into the soil beyond plant roots. In addition to a thorough review of recent research on mycorrhizal networks, this book provides readers with alternative perspectives. The book is organized into three sections: Network Structure, Nutrient Dynamics, and the Mutualism-Parasitism Continuum. Chapter 1 addresses the specificity of ectomycorrhizal symbionts and its role in plant communities, and provides an updated list of terms and definitions. Chapter 2 explores interactions between symbionts in mycorrhizal fungi networks, as well as interactions between fungal individuals. The second section of the book begins with the examination in Chapter 3 of extramatrical mycelium (mycelia beyond the root tips) in ectomycorrhizal fungi, focused on carbon and nitrogen. Chapter 4 reviews the influence of mycorrhizal networks on outcomes of plant competition in arbuscular mycorrhizal plant communities. Chapter 5 discusses nutrient movement between plants through networks with a focus on the magnitude, fate and importance of mycorrhiza-derived nutrients in ectomycorrhizal plants. Section 3 opens with a review of research on the role of ectomycorrhizal networks on seedling establishment in a primary successional habitat, in Chapter 6. The focus of Chapter 7 is on facilitation and antagonism in arbuscular mycorrhizal networks. Chapter 8 explores the unique networking dynamic of Alnus, which differs from most ectomycorrhizal plant hosts in forming isolated networks with little direct connections to networks of other host species in a forest. Chapter 9 argues that most experiments have not adequately tested the role of mycorrhizal networks on plant community dynamics, and suggests more tests to rule out alternative hypotheses to carbon movement between plants, especially those that include experimental manipulations of the mycorrhizal networks. Plant ecologists have accumulated a rich body of knowledge regarding nutrient acquisition by plants. The editor proposes that research indicating that mycorrhizal fungi compete for nutrients, which are then delivered to multiple hosts through mycorrhizal networks, represents an important new paradigm for plant ecologists.
