Book Description
Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems. Coupled with this, users will find a discussion of management approaches applicable in different regions that are illustrated with relevant case studies. In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. Provides up-to-date reviews of research findings and management strategies using international examples Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach Reveals the relevance of this scientific understanding to managers and policymakers

Book Description
In 2009–10 the U.S. Geological Survey (USGS) collected physical habitat information and benthic macroinvertebrates at 40 wadeable sites on 25 perennial streams on the Island of Maui, Hawaiÿi, to evaluate the relations between the macroin-vertebrate assemblages and environmental characteristics and to develop a multimetric invertebrate community index (ICI) that could be used as an indicator of stream quality. The macroinver-tebrate community data were used to identify metrics that could best differentiate among sites according to disturbance gradients such as embeddedness, percent fines (silt and sand areal cover-age), or percent agricultural land in the contributing basin area. Environmental assessments were conducted using land-use/land-cover data and reach-level physical habitat data.

Book Description
An important guide to assessing and managing the environment from a landscape perspective Ecological relationships are nested within the landscape. Identifying the relevant spatial and temporal scales is critical for an effective understanding of ecological functions that human societies depend upon. Moreover, human encroachment into natural areas, or changes in climate, can alter spatial relationships, which in turn can negatively affect vital plant and wildlife patterns—and weaken economic structures needed to sustain human societies. This book is the first to combine multiple disciplines into one cohesive strategy to study these crucial connections, and looks toward building a social paradigm that embraces the dynamics of ecological systems. This book: Integrates landscape ecology, environmental risk assessment, valuation of ecological goods and services, and environmental management decision processes into one single source Includes chapters on quantitative measures, Bayesian modeling,¿economic analysis, and sustainable landscapes Covers marine, forest, agricultural, and pharmaceutical risk assessment Has a chapter on predicting climate change risk to ecosystems Has a companion ftp site with color graphics, animations, and risk assessment tools With material that is accessible across all knowledge levels, Environmental Risk Assessment and Management from a Landscape Perspective moves beyond looking solely at chemical contaminants to diagnose environmental threats, and aims to accomplish practical risk assessment in a manner that supports long-term sustainable management.

Book Description
The Technical Advisory Group (TAG) on biodiversity, hereafter called Biodiversity TAG, is composed of 25 international experts in ecology, biodiversity indicators, agronomy, life cycle assessment, livestock production systems, and environmental science. Their backgrounds, complementary between systems and regions, allowed them to understand and address different perspectives. The aim of the methodology developed in these guidelines is to introduce a harmonized international approach for assessing the impacts of livestock on biodiversity. The livestock sector is a major user of natural resources (land in particular) and an important contributor to pollution (e.g. causing nutrient losses, increasing greenhouse gas emissions), which makes it one of the sectors with the highest impact on biodiversity. At the same time, livestock production is one of the few sectors with not only negative but also positive impacts on biodiversity; therefore, the sector can pull two levers to improve its biodiversity performance – mitigate harm and maximize benefits. Many environmental assessments of the livestock sector have not addressed biodiversity because of its intrinsic complexity. These guidelines strive to include biodiversity in environmental assessments, in order to increase the understanding of the impacts of livestock on biodiversity and to reveal possible synergies or trade-offs with other environmental criteria or Sustainable Development Goals (SDGs). Several indicators in these guidelines are also of relevance for the UN Decade on Ecosystem Restoration.

Book Description
Fast changing legislation and increasing environmental awarenesswithin the non-scientific community demands that the modernapproach to the management of rivers and water resources should bebased on a sound understanding and application of the scientificand ecological principles that underlie freshwater processes. Intwo volumes, The Rivers Handbook offers an expert andexhaustive insight into the principles, methods and tools of modernriver management - always within an integrated and environmentallyacceptable framework. This second volume develops the principlesand philosophies expounded in the first volume into the managementsphere, organizing the approach around problems, diagnosis andtreatment. A fully comprehensive reference to sound methods of modernriver management. The ideal information resource for all river managers.
