Book excerpt: Anthropogenic impacts are a threat to rivers worldwide, and aquatic insects are important to assessing environmental change. In the 1980s, researchers preformed collections of macroinvertebrates on submerged woody debris in the Ogeechee River (Georgia, USA) for two years. We collected invertebrates from 2015 to 2017 with the same methodology to compare communities. We documented greater taxonomic richness and change in community structure compared to the 1980s. We also documented a decline in total insect biomass; however, overall abundance was similar, indicating a decline in size of individuals. Specifically, larger consumer taxa mostly decreased, while smaller consumer taxa and most predator taxa increased in number. Additionally, functional trait richness of the community increased over three decades, but functional dispersion has not changed. Focusing on caddisflies, we examined ecological basis of change and larval morphology of an understudied genus. These results provide a unique perspective on long-term environmental changes in river systems.

This book was released on 2019 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Understanding how the structure and function of aquatic communities vary across space and time is essential for proper management of freshwater ecosystems. Current management relies on rapid biomonitoring using metrics of community structure, but metrics that incorporate ecosystem processes and functions are only just beginning to see use in assessment and management. Food webs inferred from known species interactions have been proposed as a method of incorporating function into bioassessment without expending extra effort or sacrificing the cost-effectiveness of current monitoring schemes. To apply food webs in biomonitoring, it is first necessary to understand how communities and food webs vary across temporal and longitudinal gradients so that changes can be interpreted correctly. I conducted a study to establish such a baseline for the Ogeechee River, a large coastal plain blackwater river in the southeastern United States. Samples of invertebrate assemblages were taken quarterly for three years from 6 sites along the main course of the Ogeechee River. I then investigated the spatial and seasonal structure of communities and food webs. Food webs were inferred using a database of invertebrate diets compiled from the literature. Communities varied across sites and seasons, with lower diversity and more lentic and estuarine taxa at downstream sites, and lower diversity during the flood pulse in the winter and spring due to high numbers of certain dominant taxa. Food web structure changed little over time and space, with some diversity dependent increases in links, linkage density and connectance at upstream sites, and some diversity independent decreases in prey to predator ratios during the winter. Results suggest that community structure was both more informative and reliable than food web structure for detecting changes in river communities. Better documentation of species interactions in the literature could improve inferred food webs so that they could work as a supplemental tool for interpreting the results of biomonitoring and for making management decisions.

Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.

Available in PDF, EPUB and Kindle. Book excerpt: Feeding Ecology of Fish establishes a comprehensive framework for the variable ecological patterns exemplified by feeding fishes. The author, a former president of the American Fisheries Society, devotes special attention to synthesizing empirical studies in categorizing feeding patterns. This book shows how remarkably adaptable fish can be with regard to selecting food, often from trophic levels not usually occupied. Relying on a thorough literature survey, Feeding Ecology of Fish will be an invaluable reference for both fishery scientists and ecological theorists. Organization by trophic level Emphasis on empirical studies Broad coverage of a diverse field

This book was released on 2007-07-12 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Available in PDF, EPUB and Kindle. Book excerpt: “Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent’s major wetland types.” Arnold van der Valk, Iowa State University “Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available—a must for wetland scientists and managers.” Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America’s diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent’s wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you’ll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book—I’m impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts–Amherst
