Nonindigenous Mollusks Distribution Information

This site has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency More...

Development of Ecological Indicator Guilds

The whole study, conducted at Fort Benning, Georgia, partially funded through the US Army, involves testing of water and soil quality, physical and biotic indicators of stress at both the population and community level. Anthropogenic stress in the present study comes from disturbance by vehicles, particularly tanks used in army training, and from More...

Trophic coupling and habitat connectivity among coral reef, mangrove, and seagrass fishes and benthic invertebrate communities of the Virgin Islands National Park (VIIS) and Coral Reef National Monument (VICR)

The connection between fish habitat utilization, prey use, and fish movement patterns is not known in relation to available invertebrate prey resources in off-reef sites. Developing a better understanding of the habitat use, diet, and resource needs of benthic communities and their interactions with mobile fish and invertebrates is an important More...

Genetic population structure of the green floater (Lasmigona subviridis): Identification of management units and associated fish hosts

Freshwater bivalves, which are among the most threatened animals in North America, present significant challenges to conservation biologists that attempt to maintain ecological and evolutionary processes within and among populations. Effective management of this rare fauna is often complicated because inadequate information exists for More...

Effect of Benthic Invertebrate Populations, Riparian Zone and Associated Water Quality on Infection Rates of Tubifex tubifex with Myxobolus cerebralis

The primary goal of this study is to clarify how riparian zone and land use affect T. tubifex population density, lineage and myxosporidian parasite density and/or the ability of resident worms to become infected with M. cerebralis spores and to release infective spores. Preliminary results suggest that a deciduous riparian zone reduces the More...

National Resources Monitoring Partnership (NRMP)

Natural resource managers face complex decisions that require a clear understanding of the status of wildlife populations and their habitats. Monitoring is key to making effective management decisions and evaluating the outcomes of those decisions. The goal of NRMP is to improve the accessibility of monitoring efforts to resource managers to aid More...

National Resources Monitoring Partnership (NRMP) Newsletter

Natural Resource Monitoring Partnership (NRMP) is a collaborative effort by the natural resource management community to improve monitoring efforts in order to support effective evaluation and decision-making by sharing information on monitoring projects and protocols. The Natural Resource Monitoring Partnership was built for easy access to More...

Effects of Thinning and Prescribed Fire on Aquatic and Terrestrial Herpetofauna: Little River Adaptive Management Area

Prescribed fire and forest thinning is a management strategy that promotes the development of forest structure and composition similar to that present under a native fire regime. This research summary describes how FRESC researchers will address the effects of prescribed fire and forest thinning on the diversity, abundance, and habitat More...

Relationships Among Flow, Water Depth, Sediment Texture, and Fingernail Clams

Fingernail clams (Sphaeriidae) and mayflies (Ephemeroptera) are important food sources for fish and migrating waterfowl in the Upper Mississippi River (UMR). An empirical model is being tested to determine its ability to confidently identify preferred areas for fingernail clams in UMR Pools 7 and 8. The intended result of this model is to provide More...

Mussel Conservation Activities

Mussel Conservation Activities are conducted in the upper Mississippi River. These activities include the genetic studies, mussel and cage cultures, and cleaning and stocking mussels. This resource, published by Fish and Wildlife Service, contains highlights of research done on mussels from 1982-2006.
