    dct:description "These data were used to describe a possible approach to estimate changes in invertebrate taxa richness at sites across the United States with known water-quality trends but no invertebrate data. This data release consists of invertebrate, water-quality, and covariate data from 1,322 sites and water-quality, covariate, and trend result data from an additional 259 sites with reported water-quality trends but no invertebrate data. Collectively, these data were used to describe invertebrate response to total nitrogen, total phosphorus, or specific conductance and to estimate changes in invertebrate taxa richness in response to changes in water-quality. Description of data processing and analysis are documented in the associated publication (Zuellig and Carlisle, 2021)." ;
