Modelling Of Dreissenid Mussel Impacts On Lake Michigan, Chunqi Shen
Theses and Dissertations
Invasive dreissenid mussel appear to have profoundly altered Great Lakes food webs and nutrient cycles during the past several decades. Recent declines of phytoplankton were supposed to be highly related with the increase of mussel population. These phytoplankton declines were further found to be coincident with declines in the abundance of planktivorous fish. In addition, the resurgence of Cladophora in Great lakes was estimated to be associated with the high density colonization of mussels. More light is available at lake bottom due to the mussels’ graze effect. The mussels further promote Cladophora growth by fertilizing it with nutrient-rich excrement. And …

International Congress on Environmental Modelling and Software
Entrance of nutrients and sediments to water bodies (i.e. Lakes) originating from watersheds is a serious problem in the Iran and other countries. So, the identification of critical source areas (CSAs) of pollutants in terms of watershed hydrologic units is extremely important for effective management of pollutant sources and implementation of best management practices for better protection of water quality. The main objective of this study was to identify and evaluate critical source areas (CSAs) of Nutrient loads using an integrated modeling approach. For this, Soil and Water Assessment Tool (SWAT) was used to identify CSAs of nutrients in the …
