The ongoing growth of human populations within US coastal regions continues to increase habitat loss, eutrophication, organic loading, overfishing, and other anthropogenic stressors in estuarine waters. The National Estuarine Research Reserve System (NERRS) is a federally funded initiative that addresses these critical estuarine problems and coastal resource issues at 25 sites in 21 states. Now estuarine and watershed scientists, resource managers, community planners, and other professionals dealing with coastal zone issues have an expert resource describing the NERRS program, organization, goals, and management strategy. Estuarine Research, Monitoring, and Restoration first defines the components and technical aspects of the NERRS program, then provides valuable insight into the program through the presentation of six case studies of NERRS sites. This book examines estuarine problems including degraded water quality, reduction of biodiversity, and problematic invasive species, then analyzes the human impacts affecting estuaries. The comprehensive analysis of the six estuarine reserve locations characterizes each region's physical, chemical, and biological conditions from the perspective of the NERRS program. These case studies include a cross section of sites from three coasts, each study emphasizing the importance of unified efforts of government and citizens to successfully maintain the ecology of these critical areas.

Many infectious diseases of recent concern, including malaria, cholera, plague, and Lyme disease, have emerged from complex ecological communities, involving multiple hosts and their associated parasites. Several of these diseases appear to be influenced by human impacts on the environment, such as intensive agriculture, clear-cut forestry, and habitat loss and fragmentation; such environmental impacts may affect many species that occur at trophic levels below or above the host community. These observations suggest that the prevalence of both human and wildlife diseases may be altered in unanticipated ways by changes in the structure and composition of ecological communities. Predicting the epidemiological ramifications of such alteration in community composition will require strengthening the current union between community ecology and epidemiology. Disease Ecology highlights exciting advances in theoretical and empirical research towards understanding the importance of community structure in the emergence of infectious diseases. To date, research on host-parasite systems has tended to explore a limited set of community interactions, such as a community of host species infected by a single parasite species, or a community of parasites infecting a single host. Less effort has been devoted to addressing additional complications, such as multiple-host-multiple-parasite systems, sequential hosts acting on different trophic levels, alternate hosts with spatially varying interactions, effects arising from trophic levels other than those of hosts and parasites, or stochastic effects resulting from small population size in at least one alternate host species. The chapters in this book illustrate aspects of community ecology that influence pathogen transmission rates and disease dynamics in a wide variety of study systems. The innovative studies presented in Disease Ecology communicate a clear message: studies of epidemiology can be approached from the perspective of community ecology, and students of community ecology can contribute significantly to epidemiology.
