Adult Walleyes were collected with gill nets from natural lakes in Iowa during spring and then were transported to a hatchery, where they were measured, sexed, and tagged. One worker injected 752 Walleyes (mean TL = 21.8 in; SE = 0.16) with two identical VI tags; each side (left and ...

Large-bodied herbivores are unique in their capacity to consume large quantities of plant biomass and, as the largest terrestrial animals, they are uniquely capable of causing disturbance to vegetation and soils. These taxa thus exert strong top-down control on ecological communities and ecosystem pro...
Based upon other notable invasions that had cascading effects through the entire food web (e.g. zebra mussel invasion in the Great Lakes; (Rennie et al., 2009; Roberts, 1990)), we hypothesized that filter feeding bigheaded carps would impact all levels of the food web because of the dire...

Historically, hydraulic conditions were presumed to be either a single well-mixed unit (lakes), or plug flow (rivers, wetlands). Removal was presumed to be a first-order process, with rates varying in proportion to the water concentration ([34,81–83]). The calibration parameter is the ...
