Analysis of the Benthic Macroinvertebrate Community of a Fluctuating River-Reservoir Zone in Middle Tennessee
OBIS-USA brings together marine biological occurrence data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. Waters or with U.S. funding. Coordinated by the Science Analytics and Synthesis (SAS) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biogeographic Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization) International Oceanographic Data and Information...
Empirical data supporting a non-lethal method for characterizing the reproductive status and larval development of freshwater mussels (Bivalvia: Unionida)
Here we present the data collected during a mark-recapture study on freshwater mussels in Bruce Creek, Walton County, Florida. These data were used to evaluate the non-lethal impacts of a gill sampling protocol to assess gravidity of freshwater mussels. Data were collected every four weeks, or as weather permitted, to be able to monitor the reproductive status of each mussel every month of the year. The dataset includes unique tag numbers to identify specific female mussels captured and recaptured during this study. Genus and species were identified, and the gravidity status was evaluated for each individual mussel.
This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...
