Project Description
A strong relation exists between the solute composition of water and the occurrence of mollusks. Solute composition refers to bicarbonate-carbonate, sulfate, and chloride anions, and sodium, calcium, and magnesium cations that make up the dominant ions within natural waters. Concentration can be considered to be the sum of ion concentration per liter and expressed as total dissolved solids (TDS) in solution.
Because solute composition is influenced by climate variation, hydrologic setting and process, and local geology baseline data on solute composition could be a valuable tool for the management of springs and wetlands. Solute composition can add to our understanding of the distribution of particular genera and management decisions where solute composition may be a consideration include the enhancement or mitigation of wetlands, change in lake or wetland volume, and change in taxa mortality rate or assemblage composition. Investigation along these lines may also result in significant implications for assessing the long-term stability and sensitivity of habitats, sustaining threatened, sensitive, or endemic taxa, and designing conservation programs.
