- A long-term study shows the trophic state of Missouri reservoirs reflects the physiography and human alteration of their drainage basins (Jones et al. 2008a). The proportion of cropland cover in the catchment of these artificial lakes (a surrogate for nutrient loss from agriculture) along with metrics of morphology and hydrology account for much of the among-system variation in both phosphorus and nitrogen (Jones et al. 2004, 2008b). Some of these midcontinent water bodies support measureable levels of microcystin, an algal toxin, during summer (Graham et al. 2004, Graham and Jones 2007). Studies of regional limnology in several Asian countries have shown how the summer monsoon influences lake trophic state (Jones et al. 2006).
