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.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Asian clam, Corbicula fluminea, is a broadly distributed and abundant invasive species, yet many aspects of its population biology (e.g., growth and condition in relation to environmental variables) are not well understood. Based on previous research by other investigators, we hypothesized that abundance, population growth rate, and individual growth rate of C. fluminea would increase with temperature, chlorophyll-a, and dissolved oxygen. We sampled C. fluminea at two sites (Kalama and Blurock) in the lower Columbia River (CR), USA. Modal progression analyses indicated a life span of 2-3 years, with new young-of-the-year recruits ( 15 mm), one-year old (13-25 mm), two-year old (20-33mm), and three-year old (30-43mm) clams present. A generalized linear mixed model (GLMM) predicting the abundance of C. fluminea indicated a significant negative association with chlorophyll-a concentration, whereas a GLMM predicting the population growth rate of C. fluminea indicated a significant positive association with dissolved oxygen. The GLMM predicting the individual growth rate of C. fluminea indicated the individual growth rate was not significantly related to any individual environmental variable, however the interaction between temperature and year was significant. The morphological condition (weight at length) of C. fluminea varied significantly between our two sites, with smaller clams (

Download or read book Ecology written by W. D. Russell-Hunter and published by Elsevier. This book was released on 2013-09-24 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mollusca, Volume 6: Ecology provides an overview of the state of knowledge in molluscan ecology. It is part of a multivolume treatise that covers the fields of biochemistry, physiology, neurobiology, reproduction and development, evolution, ecology, medical aspects, and structure. The Mollusca is intended to serve a range of disciplines: biological, biochemical, paleontological, and medical. As a source of information on the current status of molluscan research, it should prove useful to researchers of the Mollusca and other phyla, as well as to teachers and qualified graduate students. The book contains 15 chapters, arranged into three levels of ecological perspective: (a) distributional studies; (b) physiological ecology and bioenergetics; and (c) population genetics and dynamics. A discussion of the planetary distribution of and ecological constraints upon the mollusca is followed by separate chapters on the life styles and distribution of mollusks on the deep-sea bottom, in mangroves, and on coral reefs; and the trophic and reproductive ecology of those intrinsically fascinating molluscan groups—the nudibranchs and cephalopods. Subsequent chapters present physiological ecology in land snails and in freshwater bivalves, prosobranchs, and pulmonates, with a survey of the techniques of actuarial bioenergetics as applied to nonmarine molluscs. Other chapters cover population dynamics and biology in an introduced pest species, population genetics of marine molluscs, ecogenetics of land snails, and life-cycle pattems throughout the major molluscan taxa.
Download or read book The Comparative Roles of Suspension Feeders in Ecosystems written by Richard F. Dame and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals are a major link between the water column (pelagic) and the bottom (benthic) habitats in most shallow systems. This coupling is dominated by active processes such as suspension-feeding in which the organism actively uses energy to pump water that is then filtered to remove suspended particles that are consumed while undigested remains are deposited on the bottom. As a result of this feeding on and metabolism of particles, the animals excrete dissolved inorganic and organic waste back into the water column, and thus, become major components in the cycling and feedback of essential elements. With relatively high weight specific filtration rates of 1— 10 liters/hour/gram dry tissue and a propensity to form large aggregated populations (beds, reefs, schools and swarms), these organisms can play an important role in regulating water column processes Although estuarine bivalve molluscs such as oysters and mussels dominate the suspension-feeder literature, other groups including plankton and nekton that are found in estuarine as well as other aquatic systems are also potentially important removers of suspended particles. Thus, a significant part of the NATO Advanced Research Workshop focused on suspension-feeders as controllers of plankton abundance, biomass and diversity, system metabolism, nutrient cycling and scale dependency. Systems dominated by suspension-feeders are typically impacted by human activities including recreation, aquaculture, human and industrial pollution, and bilge water from shipping. Suspension-feeders are often impacted by fisheries and over-exploitation. These impacts commonly result in changes in ecosystem structure either through the food chain concentration of harmful substances or diseases, the introduction of alien species of suspension-feeders, or the instability of suspension-feeders systems through species displacement or phase shifts in the dominance between different suspension-feeding components such as nekton or zooplankton. These issues were addressed near the close of the workshop along with conclusions and syntheses developed by the working groups.
Download or read book Invasive Animals and Plants in Massachusetts Lakes and Rivers written by Wai Hing Wong and published by CRC Press. This book was released on 2023-05-10 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing demand for appropriate management of aquatic invasive species in lakes and rivers worldwide. This book covers biology, invasion ecology, sightings, and control techniques of 4 invasive animals and 15 invasive plants in Massachusetts lakes and rivers. It provides valuable information on their biological characteristics and potential expansion pathways, as well as monitoring and management, including alternative management tools using updated biological, chemical, and mechanical methods. The book also includes the regulation of invasive species management to allow resource managers, biologists, practitioners, volunteers, and students a better understanding of compliance and enforcement with environmental law. An example of successful management is highlighted for each invasive species. Invasive Animals and Plants in Massachusetts Lakes and Rivers is the first book to provide comprehensive and systematic coverage and illustrations for both freshwater invasive animals and plants. Although focussing on Massachusetts, it will provide readers with the bigger picture on multiple invasive species, from prevention, early detection, control, ecological restoration, to public education. Natural resource managers in Massachusetts and surrounding states will glean the detailed and valuable information they need to learn and use to prevent and manage freshwater invasive species in the field.
