Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Download or read book The Importance of the Freshwater Landscape Connectivity and Regional Processes for Understanding Spatial Patterns and Drivers of Lake Stream and Wetland Properties at Macroscales written by Katelyn Beth Shank King and published by . This book was released on 2021 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater ecosystems are a good model for studying questions associated with environmental change because their nutrients and biota reflect changes in their surrounding watershed. Although many studies of fresh waters focus on understanding how the terrestrial landscape affects lake, stream, and wetland properties, it is becoming more widely recognized that we must also consider the freshwater landscape, including connections (or lack thereof) among surface waters, to understand and manage freshwater ecosystems. However, freshwater types continue to be studied individually (e.g., lakes or streams or wetlands) or at relatively local scales (e.g., an individual lake to tens of lakes within a watershed), whereas environmental changes such as land use intensification, climate change, and the spread of non-native species affect all freshwater types and often occur at broad spatial scales such as regions, continents, and the globe. Understanding patterns of freshwater properties at broad-extents can be complicated by the influence of drivers operating at different spatial scales (i.e. cross-scale interactions). An emergent specialty in ecology, macrosystems ecology, provides a framework for broad-extent, multi-scale, and cross-freshwater type studies, improving predictions and contributing to the understanding of freshwater ecosystem responses to change at the regional to continental extents relevant for management and policy. In addition, the recent rise of open science perspectives and advancements in computational tools makes it possible to collate data and perform analysis at the macroscale. My dissertation uses this theoretical foundation and publicly-available databases to understand macroscale patterns in nutrients and fish biodiversity across freshwater types and the processes that may underlie those patterns.In my first chapter, I compiled total phosphorus, total nitrogen, chlorophyll a, and percent macrophyte cover from over 3,500 lakes, streams, and wetlands sampled by the Environmental Protection Agency's National Aquatic Resource Surveys across the continental U.S. This research led to the understanding that these different freshwater types may share similar patterns and drivers of nutrients across the U.S., but different patterns and drivers for biotic properties. For my second chapter, I further investigated biotic properties across lakes and streams, specifically focusing on fish biodiversity patterns and connections between lakes and streams. I used fish data from 559 lakes and 854 streams from the midwestern/northeastern U.S. and found that discrete connectivity classes helped explain variation in fish species composition and richness across lakes and streams. My third chapter is a data paper that describes methods for creating a database (LAGOS-NETWORKS) that includes a suite of surface connectivity metrics for 86,511 lakes and 898 networks in the U.S. This is the first database to provide accessible and comprehensive lake network metrics at the national scale. LAGOS-NETWORKS was used in my final chapter, where I used these continuous connectivity metrics and other multi-scale drivers to investigate how the effects of connectivity on fish species richness change with regional-scale land use. I found that connectivity had different effects on lake and stream fish species richness depending on regional-scale agricultural land use, showing a cross-scale interaction (CSI) and the effect of this CSI differed by freshwater type. Collectively, my dissertation uses multi-scale, cross-scale, and an integrated freshwater landscape approach to further understand patterns and processes in aquatic ecosystems at the macroscale.
Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Download or read book The Riverine Ecosystem Synthesis written by James H. Thorp and published by Elsevier. This book was released on 2010-07-27 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the most comprehensive model yet for describing the structure and functioning of running freshwater ecosystems. Riverine Ecosystems Synthesis (RES) is a result of combining several theories published in recent decades, dealing with aquatic and terrestrial systems. New analyses are fused with a variety of new perspectives on how river network ecosystems are structured and function, and how they change along longitudinal, lateral, and temporal dimensions. Among these novel perspectives is a dramatically new view of the role of hydrogeomorphic forces in forming functional process zones from headwaters to the mouths of great rivers. Designed as a useful tool for aquatic scientists worldwide whether they work on small streams or great rivers and in forested or semi-arid regions, this book will provide a means for scientists to understand the fundamental and applied aspects of rivers in general and includes a practical guide and protocols for analyzing individual rivers. Specific examples of rivers in at least four continents (Africa, Australia, Europe and North America) serve to illustrate the power and utility of the RES concept. Develops the classic, seminal article in River Research and Applications, "A Model of Biocomplexity in River Networks Across Space and Time" which introduced the RES concept for the first time A guide to the practical analysis of individual rivers, extending its use from pristine ecosystems to modern, human-modified rivers An essential aid both to the study fundamental and applied aspects of rivers, such as rehabilitation, management, monitoring, assessment, and flow manipulation of networks

This book was released on 2002-09-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: We all rely on a familiar set of indicators - interest rates, unemployment, inflation, the Dow Jones index, and GDP, for example - to gauge the performance of national economies. No such measures are currently available to describe the environment. This book lays out a blueprint for periodic reporting on the condition and use of ecosystems in the United States. Developed by experts from businesses, environmental organizations, universities, and federal, state, and local government agencies, it is designed to provide policymakers and the general public with a succinct and comprehensive - yet scientifically sound and non-partisan - view of 'how we are doing'. This book should prove invaluable for decision makers in natural resource management and environmental policy in government and environmental organizations, businesses, and trade associations; academics with a research or teaching interest in environmental issues; and the general public interested in the continued well-being of American ecosystems.
Download or read book Tropical Stream Ecology written by David Dudgeon and published by Elsevier. This book was released on 2011-05-04 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates.

The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. First synthetic account of the ecology of all types of tropical streams Covers all of the major tropical regions Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems Threats faced by tropical stream ecosystems and possible conservation actions Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
Download or read book Drought and Aquatic Ecosystems written by P. Sam Lake and published by John Wiley & Sons. This book was released on 2011-06-09 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Droughts are a major hazard to both natural and human-dominated environments and those, especially of long duration and high intensity, can be highly damaging and leave long-lasting effects. This book describes the climatic conditions that give rise to droughts, and their various forms and chief attributes. Past droughts are described including those that had severe impacts on human societies. As a disturbance, droughts can be thought of as “ramps” in that they usually build slowly and take time to become evident. As precipitation is reduced, flows from catchments into aquatic systems decline. As water declines in water bodies, ecological processes are changed and the biota can be drastically reduced, though species and populations may survive by using refuges. Recovery from drought varies in both rates and in degrees of completeness and may be a function of both refuge availability and connectivity. For the first time, this book reviews the available rather scattered literature on the impacts of drought on the flora, fauna and ecological processes of aquatic ecosystems ranging from small ponds to lakes and from streams to estuaries. The effects of drought on the biota of standing waters and flowing waters and of temporary waters and perennial systems are described and compared. In addition, the ways in which human activity can exacerbate droughts are outlined. In many parts of the world especially in the mid latitudes, global warming may result in increases in the duration and intensity of droughts. Drought and Aquatic Ecosystems is essential reading for freshwater ecologists, water resource managers and advanced students.
