The Routledge Handbook of Wetlands
No full textThis handbook provides a comprehensive and interdisciplinary overview of the place, value and significance of wetlands, presenting perspectives from across the environmental and social sciences.
Recent decades have witnessed unprecedented global interest in wetlands and the critical role they play in supporting biodiversity and ecosystem services such as carbon storage, flood mitigation, as well as their direct benefits for people and society that include the provision of food, clean water and a range of cultural services. This Routledge Handbook of Wetlands brings together a wide range of perspectives from social and environmental disciplines, and voices from different wetland stakeholders from the global north and south, to present an assessment of our current understanding of wetlands, their environmental significance, and their place in society and policy. A recurring theme of the book is an exploration of how our current knowledge of wetlands, that is often fragmented along traditional disciplinary lines, can be brought together to enable a more integrated, interdisciplinary and social-ecological conceptualisation that aligns more closely with real-world complex challenges, and which offers new directions in wetland management for sustainable development.
This handbook will be essential reading for students and scholars of wetland management, environmental science, water resource management, conservation ecology, environmental humanities and sustainable development
Wetlands, Geographical Information Systems (GIS) and Spatial Modelling
No full textGeographical Information Systems (GIS) and spatial modelling play a vital role in the research and management of wetlands. This chapter examines the integration of GIS and spatial modelling in wetland studies, emphasising its applications in wetland mapping and classification, hydrological modelling, habitat assessment, biodiversity conservation and restoration, and socio-economic analysis. By utilising software such as ArcGIS and QGIS, researchers can analyse complex datasets, detect environmental changes, and assess the impacts of climate change on these valuable ecosystems. Challenges such as data availability and the requirement of high-resolution data are discussed, along with emerging technologies like drones for enhanced monitoring capabilities
Ecohydraulics: An Integrated Approach
No full textEcohydraulics: An Integrated Approach provides a research level text which highlights recent developments of this emerging and expanding field. With a focus on interdisciplinary research the text examines:– the evolution and scope of ecohydraulics interactions between hydraulics, hydrology, fluvial geomorphology and aquatic ecology the application of habitat modelling in ecohydraulic studies state of the art methodological developments and approaches detailed case studies including fish passage design and the management of environmental flow regimes research needs and the future of ecohydraulics research The contributions offer broad geographic coverage to encapsulate the wide range of approaches, case studies and methods used to conduct ecohydraulics research. The book considers a range of spatial and temporal scales of relevance and aquatic organisms ranging from algae and macrophytes to macroinvertebrates and fish. River management and restoration are also considered in detail, making this volume of direct relevance to those concerned with cutting edge research and its application for water resource management. Aimed at academics and postgraduate researchers in departments of physical geography, earth sciences, environmental science, environmental management, civil engineering, biology, zoology, botany and ecology; Ecohydraulics: An Integrated Approach will be of direct relevance to academics, researchers and professionals working in environmental research organisations, national agencies and consultancies

Incorporating hydrodynamics into ecohydraulics: the role of turbulence in the swimming performance and habitat selection of stream-dwelling fish
No full textThe complexity and dynamism of river systems, the
strength of their biophysical linkages and the need to
respond to adverse anthropogenic impacts has led to the
emergence of hydroecology as a key area of interdisciplinary
research. A sub-discipline of hydroecology known as ecohydraulics has emerged from the scientific literature in recent decades and, as a contemporary science, has its roots in the hydraulic stream ecology paradigm. Ecohydraulics relies on the assumption that flow forces are ecologically relevant (i.e. that they influence the fitness of individual organisms and, therefore, the structure and function of aquatic communities). It lies at the interface of hydraulics and ecology where new approaches to research are required to reconcile the contrasting conceptual frameworks underpinning these sciences, which can be seen respectively as Newtonian (reductionist) and Darwinian (holistic). River habitat is structured at a number of scales but it is at the microscale (<10−1 m) of the hydraulic environment where reductionist explanations for ecological phenomena are most often sought
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
