Book Description
The ovipositional responses of female Culex tarsalis to semiochemicals produced by aquatic organisms in three aquatic guilds (predaceous insects, algivorous fish and predatory/larvivorous fish) were examined in laboratory choice assays. Previous binary choice trials have shown that female mosquitoes avoid laying eggs on water that contains fish exudates and will instead choose to oviposit on water without kairomones released by fish. Culex tarsalis was not deterred from ovipositing in cups containing semiochemicals from invertebrate predators and algivorous fish, but was deterred from ovipositing in cups containing arroyo chub semiochemicals.

Book Description
Instead of focusing exclusively on the Lewis and Clark expedition, the authors concentrate on what Lewis was doing immediately before and after his journey through Western territory. They assess his role as a natural scientist and as governor of the Louisiana Territory.

Book Description
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.

Book Description
Covering the theory and practice of non-insecticidal control of insect vectors of human disease, this book provides an overview of methods including the use of botanical biocides and insect-derived semiochemicals, with an overall focus on integrated vector management strategies. While the mainstay of malaria control programmes relies on pesticides, there is a resurgence in the research and utilisation of non-insecticidal control measures due to concerns over rapid development and spread of insecticide resistance, and long-term environmental impacts. This book provides examples of successful applications in the field and recommendations for future use.

Book Description
In 1966 Congress passed the National Sea Grant College Program Act to promote marine research, education, and extension services in institutions along the nation's ocean and Great Lakes coasts. In Maryland a Sea Grant Program -- a partnership among federal and state governments, universities, and industries -- began in 1977, and in 1982 the University of Maryland was named the nation's seventeenth Sea Grant College. The Maryland Sea Grant College focuses its efforts on the Chesapeake Bay, with emphasis on the marine concerns of fisheries, seafood technology, and environmental quality. The introduction and transferring of organisms from one ecosystem to another has a history that is as old as human migration. Some translocations have had commercial and ecological benefits; many others have been problematical, if not detrimental, to the environment. This book examines a number of case studies of translocating aquatic plants and animal species, in the context of issues that entrepreneurs, resource managers, and scientists must take into account.
