The LRSC, in collaboration with the Department of Mathematics and Statistics, Winona State University, and the Kansas Biological Survey, University of Kansas, has submitted a grant proposal to use museum specimens to assess changes in riverine food webs in response to disturbances to key system drivers. The link below provides an example of a partial dataset for the Upper Mississippi River north of Clinton, Iowa. This section of the Upper Mississippi River still retains a near-normal spring peak flow, an elevated summer low-flow, and connectivity with > 95% of its floodplain.
It is important to note that the dataset provided only covers a small fraction of the searchable data available or data provided by museums with computerized databases. Extensive databases were provided by a number of museums for rivers listed in our proposal. Additionally, most invertebrate databases are not computerized, but curators were able to provide time periods for which bivalve and gastropod specimens were available for a given river.
