Lehman JT, Doubek JP, Jackson EW. 2013. Effect of reducing allochthonous P load on biomass and alkaline phosphatase activity of phytoplankton in an urbanized watershed, Michigan. Lake Reserv Manage. 29:116–125. Phosphorus (P) concentrations have declined in the Huron River in southeast Michigan subsequent to first a municipal ordinance, and later state legislation, restricting the application o...

Communicated by Michael Sierszen The sea lamprey (Petromyzon marinus) is an important invasive parasitic species in the Laurentian Great Lakes, but the nutritional subsidies supporting the protracted filter feeding ammocoete stage are not well established. We used stable isotope ratios (δC and δN) to determine themajor sources of autochthonous (aquatically produced) and allochthonous (terrestri...

The importance of allochthonous carbon to the productivity of stream ecosystems in temperate ecozones is well understood, but this relationship is less established in oligotrophic lakes. The nearshore littoral zones, at the interface of terrestrial and aquatic systems, are areas where the influence of terrestrial subsidies is likely greatest. We investigated the response of nearshore communitie...
