Book excerpt: The greatest success with the Agasicles as a biocontrol for alligator weed has been at experimental sites in Florida. The increased effectiveness of the alligator weed beetle in this area is believed to be related to the ability of the insect to overwinter. The Agasicles population usually has two peaks of activity in Florida as compared with one in other states. Alligator weed mats present at the beginning of the study reported herein have decreased in size and thickness. Plant competition has played an important role in controlling the alligator weed at the Goose Creek site by Agasicles and at several other sites in the southeastern states. The feeding of the Agasicles on alligator weed decreases its ability to compete with other aquatic plants. Other insects may be used to extend control over a greater geographic area. (Author).
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 454 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 Biological Invasions and Its Management in China written by Fanghao Wan and published by Springer. This book was released on 2017-04-25 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses invasive-species problems in agriculture, forests and aquatic ecosystems, highlighting the invasive mechanisms and management of the selected invasive species. Biological invasion has become a serious global ecological and economic problem that deserves particular attention from both government officials and scientists. This volume focuses on three key scientific areas: 1) population establishment and spreading mechanisms of the selected invasive species; 2) ecology adaptation, population growth, expansion and evolution of invasive species; and 3) impact of bio-invasion on the ecosystem structure and function at community and ecosystem levels. The presented research will result in techniques for better management of invasive species.

Available in PDF, EPUB and Kindle. Book excerpt: Invasive alien species are a major and growing threat to biodiversity worldwide. The transport of organisms through increased levels of trade and tourism is leading to the widespread breaching of natural biogeographic barriers at unprecedented rates. Consequences can be severe, especially in naturally isolated ecosystems. Invasive alien species can cause the extinction of vulnerable endemic species, alter the structure and composition of communities, disrupt successional pathways, and lead to the loss of ecosystem services. Global climate change may further exacerbate the spread of alien species, as climatic zones shift and potential ranges alter. The effective management of invasive alien species is clearly a priority for biological conservation worldwide. This book first provides strategies for managing such species at successive invasion stages, from prevention at the border to control of major infestations. It then describes the general tools and approaches that are recommended for successful management of particular groups of invasive organisms in a range of environments. In each case, the ecological basis and practical requirements of invasive alien species management are addressed. This integration of proven techniques and policies will be useful to a wide readership of students, academics, conservation practitioners, invasive species managers, legislators, and to the broader community concerned with biological conservation.
Download or read book Biological Control of Weeds in Australia written by M. H. Julien and published by CSIRO PUBLISHING. This book was released on 2012 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control of weeds has been practiced for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts - the technique, when practiced as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practicing biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australiawill provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students. KEY FEATURES * A unique collation of information for Australian weed research and management * Contains all the information about biological control of weeds in Australia in one book * Provides key references for further information * Will become a well cited publication

Download or read book Aquatic Plant Control Research Program Alligatorweed Survey of Ten Southern States written by Alfred F Confrancesco (Jr) and published by . This book was released on 1988 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alligatorweed (Alternanthera philoxeroides (Mart.) Griseb.) is an exotic South American plant introduced into the United States prior to 1897. It rapidly developed into problem levels throughout most southern states, where it outcompetes native vegetation and interferes with navigation and recreational use of waterways. Three biological control agents Agasicles hygrophila (Selman and Vogt), Amynothrips andersoni (O'Neill) and Vogita malloi (Pastrana) were released in the United States between 1964 and 1970 for the control of alligatorweed. A review of the releases and population development of these insect species was conducted through 1972 by US Department of Agriculture scientists. The objectives of this study were to: (a) determine the current extent of the alligatorweed population in each state and ascertain whether or not it occurred at problem levels, (b) define the current population levels of biocontrol agents at selected original release sites and assess their impacts on the alligatorweed population, (c) describe the current distribution of each species of biocontrol agent in each state, (d) identify environmental factors influencing the effectiveness of each biocontrol agent, and (e) provide recommendations for managers to enhance the effectiveness of each biocontrol agent in areas where control has not been achieved.

Download or read book River Ecology written by Michael A. Mallin and published by Oxford University Press. This book was released on 2023-10-26 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers have been vitally important to human populations worldwide for millennia as “highways” for inland travel, and as sources of water for drinking, cooking, cleaning, manufacturing, irrigation, and power generation, as well as repositories for human, animal, and industrial wastes. This accessible textbook takes a broad approach to river ecology, covering the basics but going beyond by including topics that are often overlooked such as blackwater streams and rivers, tidal creek ecosystems, and reservoir limnology. Since most running water (lotic) systems have been altered or impacted by human activities, there is significant emphasis on anthropogenic impacts, including sedimentation, nutrient pollution and related eutrophication issues as well as the effects of dams and river fragmentation, power plant operations, chemical contamination, wastewater treatment discharges, industrial scale livestock production, invasive species, and rural and urban storm water runoff on river ecosystems. Advances in stream and river restoration are also discussed.
