Around 6% of the Earth's land surface is covered by wetlands. Wetlands play a key role in hydrological and biogeochemical cycles, delivering multiple benefits to society: sources of water supply, flood regulation, water purification, agriculture, fisheries, and biodiversity. Hence, wetland systems are of immense socio-economic as well as ecological importance. In this research, the focus was on the Abras de Mantequilla (AdM) wetland in the tropical coastal region of Ecuador, a RAMSAR site and case study area for the EU-FP7 WETwin project. The research in this thesis involves a combination of field data collection, multivariate analysis techniques, as well as numerical modelling studies. The goal was to explore the effects of changes in hydrological forcing on the hydrodynamic and ecohydraulic responses of the wetland. The study aims to contribute to the understanding of how a tropical river-wetland system functions in terms of hydrodynamics, water quality, primary production, and biotic communities. Spatial patterns of biotic communities and environmental variables are obtained as well as spatio-temporal variability of hydrodynamics, water quality, primary productivity and fish habitat-suitability conditions. In data scarce areas and countries with financial constraints, the combination of field measurements with numerical models was extremely useful and relevant, confirming that these techniques complement each other in obtaining a better understanding of the dynamics of freshwater river–wetland systems. Studies like the present research can be used to enhance awareness about the environmental services of wetlands and stimulate cooperation between all stakeholders in order to achieve more sustainable wetland management.

While it is generally accepted that flood pulsing and disturbance dynamics are critical to wetland viability, there is as yet no consensus among those responsible for wetland restoration about how best to plan for those phenomena or even whether it is really necessary to do so at all. In this groundbreaking book, Dr. Beth Middleton draws upon the latest research from around the world to build a strong case for making flood pulsing and disturbance dynamics integral to the wetland restoration planning process. While the initial chapters of the book are devoted to laying the conceptual foundations, most of the coverage is concerned with demonstrating the practical implications for wetland restoration and management of the latest ecological theory and research. It includes a fascinating case history section in which Dr. Middleton explores the restoration models used in five major North American, European, Australian, African, and Asian wetland projects, and analyzes their relative success from the perspective of flood pulsing and disturbance dynamics planning. Wetland Restoration also features a wealth of practical information useful to all those involved in wetland restoration and management, including: A compendium of water level tolerances, seed germination, seedling recruitment, adult survival rates, and other key traits of wetland plant species A bibliography of 1,200 articles and monographs covering all aspects of wetland restoration A comprehensive directory of wetland restoration ftp sites worldwide An extensive glossary of essential terms Wetland Restoration, Flood Pulsing, and Disturbance Dynamics is a valuable working resource for wetland restoration consultants, employees of government agencies, and professional land managers, as well as ecologists, foresters, and geologists involved with wetland restoration and management. It is also an excellent text for advanced courses in wetland restoration.

The order of Catfishes (Siluriformes) is one of the largest in number of families, genera, and species. The group is found in most freshwaters and shallow saltwater bodies around the world. Its extraordinary evolutionary and biogeographic pathways leave many open questions on its origin and large diversification that make its study a complex subject, yet a fascinating field for research. Catfishes, a Highly Diversified Group is divided into two volumes. Volume 1 (Their Outstanding Biology, 14 chapters) aims to rectify the incomplete information on the enormous morphological diversity of the group, special habits and adaptations to specific environments, and morpho-functional characteristics of the catfishes. Volume 2 (Evolution and Phylogeny, 18 chapters) deals with evolutionary mechanisms and major evolutionary trends within Siluriformes, investigating new avenues concerning fossil and extant catfishes and relationships within and among families, using morphological and molecular evidence.

Filling a niche in the geomorphology teaching market, this introductory book is built around a 12 week course in fluvial geomorphology. ‘Reading the landscape’ entails making sense of what a riverscape looks like, how it works, how it has evolved over time, and how alterations to one part of a catchment may have secondary consequences elsewhere, over different timeframes. These place-based field analyses are framed within their topographic, climatic and environmental context. Issues and principles presented in the first part of this book provide foundational understandings that underpin the approach to reading the landscape that is presented in the second half of the book. In reading the landscape, detective-style investigations and interpretations are tied to theoretical and conceptual principles to generate catchment-specific analyses of river character, behaviour and evolution, including responses to human disturbance. This book has been constructed as an introductory text on river landscapes, providing a bridge and/or companion to quantitatively-framed or modelled approaches to landscape analysis that are addressed elsewhere. Key principles outlined in the book emphasise the importance of complexity, contingency and emergence in interpreting the character, behaviour and evolution of any given system. The target audience is second and third year undergraduate students in geomorphology, hydrology, earth science and environmental science, as well as river practitioners who use geomorphic understandings to guide scientific and/or management applications. The primary focus of Kirstie and Gary’s research and teaching entails the use of geomorphic principles as a tool with which to develop coherent scientific understandings of river systems, and the application of these understandings in management practice. Kirstie and Gary are co-developers of the River Styles® Framework and Short Course that is widely used in river management, decision-making and training.

Many species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.

Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world. The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate. - A 15 year collaboration by a diverse group of scientists working on the management and recovery of salmon, steelhead trout, and wildlife populations in the Pacific Northwest - Includes over 200 figures, with four-color throughout the book - Discusses complex issues such as habitat degradation, juvenile survival through the hydrosystem, the role of artificial production, and harvest reform
