Ecologists interested in assessing landscapes and ecosystems must measure biomass, cover, and the density or frequency of various key species. Recently, sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have become fine-grained, as it has become increasingly important to accurately map and assess rare species for conservation. This book lays out the range of current methods for mapping and measuring species diversity, for field ecologists, resource managers, conservation biologist, and students, as a tool kit for future measurements of plant diversity.

The papers included in this Special Issue address a variety of important aspects of plant biodiversity and genetic resources, including definitions, descriptions, and illustrations of different components and their value for food and nutrition security, breeding, and environmental services. Furthermore, comprehensive information is provided regarding conservation approaches and techniques for plant genetic resources, policy aspects, and results of biological, genetic, morphological, economic, social, and breeding-related research activities. The complexity and vulnerability of (plant) biodiversity and its inherent genetic resources, as an integral part of the contextual ecosystem and the human web of life, are clearly demonstrated in this Special Issue, and for several encountered problems and constraints, possible approaches or solutions are presented to overcome these.

The recent progress in analytical methods, aided by bringing in a wide range of other disciplines, opens up the study to a broader field, which means that biogeography now goes far beyond a simple description of the distribution of living species on Earth. Originating with Alexander von Humboldt, biogeography is a discipline in which ecologists and evolutionists aim to understand the way that living species are organized in connection with their environments. Today, as we face major challenges such as global warming, massive species extinction and devastating pandemics, biogeography offers hypotheses and explanations that may help to provide solutions. This book presents as wide an overview as possible of the different fields that biogeography interacts with. Sixteen authors from all over the world offer different approaches based on their specific areas of knowledge and experience; thus, we intend to illustrate the vast number of diverse aspects covered by biogeography.

The world relies on very few crop and animal species for agriculture and to supply its food needs. In recent decades, there has been increased appreciation of the risk this implies for food security and quality, especially in times of environmental change. As a result, agricultural biodiversity has moved to the top of research and policy agendas. This Handbook presents a comprehensive overview of our current knowledge of agricultural biodiversity in a series of specially commissioned chapters. It draws on multiple disciplines including plant and animal genetics, ecology, crop and animal science, food studies and nutrition, as well as social science subjects which explore the socio-economic, cultural, institutional, legal and policy aspects of agricultural biodiversity. It focuses not only on the core requirements to deliver a sustainable agriculture and food supply, but also highlights the additional ecosystem services provided by a diverse and resilient agricultural landscape and farming practices. The book provides an indispensable reference textbook for a wide range of courses in agriculture, ecology, biodiversity conservation and environmental studies.

One of the main objectives of nature conservation in Europe is to protect valuable cultural landscapes characterized by a mixture of open habitats and hedges, trees and patchy woodland (semi-open landscapes).The development of these landscapes during the past decades has been characterized by an ongoing intensification of land use on the one hand, and an increasing number of former meadows and pastures becoming fallow as a result of changing economic conditions on the other hand. Since species adapted to open and semi-open landscapes contribute to biodiversity in Europe in a major way, this development is of great concern to nature conservation. In several countries largescale, nature-adapted pastoral systems have been recognized as one solution to this problem. These systems could offer an alternative to industrial livestock raising and keep a high biodiversity on the landscape level. Against the background of livestock diseases such as BSE and Foot and Mouth Disease and the efforts to reform the Common Agricultural Policy in the EU by changing the criteria for agricultural subsidies, these concepts gain particular significance.They could also represent an alternative to the established, costly habitat management tools.

Based on graph theory studies this book seeks to understand how tropical species interact with each other and how these interactions are affected by perturbations in some of the most species-rich habitats on earth. Due to the great diversity of species and interactions in the tropics, this book addresses a wide range of current and future issues with empirical examples and complete revisions on different types of ecological networks: from mutualisms to antagonisms. The goal of this publication is not to be only for researchers but also for undergraduates in different areas of knowledge, and also to serve as a reference text for graduate-level courses mainly in the life sciences.

Individually and collectively, resident microbes play important roles in host health and survival. Shaping and shaped by their host environments, these microorganisms form intricate communities that are in a state of dynamic equilibrium. This ecologic and dynamic view of host-microbe interactions is rapidly redefining our view of health and disease. It is now accepted that the vast majority of microbes are, for the most part, not intrinsically harmful, but rather become established as persistent, co-adapted colonists in equilibrium with their environment, providing useful goods and services to their hosts while deriving benefits from these host associations. Disruption of such alliances may have consequences for host health, and investigations in a wide variety of organisms have begun to illuminate the complex and dynamic network of interaction - across the spectrum of hosts, microbes, and environmental niches - that influence the formation, function, and stability of host-associated microbial communities. Microbial Ecology in States of Health and Disease is the summary of a workshop convened by the Institute of Medicine's Forum on Microbial Threats in March 2013 to explore the scientific and therapeutic implications of microbial ecology in states of health and disease. Participants explored host-microbe interactions in humans, animals, and plants; emerging insights into how microbes may influence the development and maintenance of states of health and disease; the effects of environmental change(s) on the formation, function, and stability of microbial communities; and research challenges and opportunities for this emerging field of inquiry.

This book presents the polycentric and multiscale view of landscape which has been developed in Russia within a framework of physical geography since the early twentieth century. The authors develop the ideas of hierarchical organization of a landscape and strong relationships between abiotic and biotic components with equal attention to both vertical fluxes and lateral transfer. Three-dimensional representation of landscape involves strong emphasis on abiotic drivers of pattern development including relief, geological structures and runoff. The objective of this book is to demonstrate the multiplicity of models and multiscale approach to description and explanation of landscape pattern, functioning, dynamics, and evolution. The contributions deal with various hierarchical levels ranging from within-unit interior variability to between-units interaction at landscape level, as well as regional and supra-regional zonal patterns. Divided into 8 clear parts, the 28 chapters treat spatial pattern in one of the following aspects: indicator of actual matter and energy flows control over actual processes including disturbance expansion as well as determinant of future development indicator of genesis and prerequisite for future trends driver for short-term dynamics of processes response to climatic and anthropogenic influences factor of settlement network and land use adaptation at various historical epochs framework for actual land use spatial arrangement. This contributed volume is written for researchers and students in the field of landscape ecology, physical geography, environmental impact assessment, and ecological planning.
