Predicting Invasive Carp Habitat Suitability In The Minnesota River, Minnesota, Melissa Oubre
Predicting Invasive Carp Habitat Suitability In The Minnesota River, Minnesota, Melissa Oubre
All Graduate Theses, Dissertations, and Other Capstone Projects
Since the 1980's invasive carp have been expanding their range northward up the Mississippi River. Consisting of four species, grass carp (Ctenophaygodon idella), silver carp (Hypophthalmichthys molitrix), bighead carp (H. nobilis), and black carp (Mylopharyngodon piceus), these fish have the potential to naturalize and expand into large Mississippi River tributaries like the Minnesota River (MNR). Thus, understanding the likelihood of naturalization in these tributaries is vital in guiding prevention or mitigation efforts. This study evaluates the environmental suitability of the Minnesota River, the largest tributary to the Mississippi in Minnesota, for invasive carp. Environmental suitability for invasive carp is modeled …
The Effects Of Surface Albedo And Initial Lignin Concentration On Photodegradation Of Sorghum Bicolor Litter, Joshua Niere
The Effects Of Surface Albedo And Initial Lignin Concentration On Photodegradation Of Sorghum Bicolor Litter, Joshua Niere
All Graduate Theses, Dissertations, and Other Capstone Projects
Photodegradation has been recognized as a contributor to litter decomposition in a wide variety of ecosystems, however many of the mechanisms that drive it remain unknown. The primary focus of this study was to investigate the effect of surface albedo on the rate at which plant litter photodegrades. The first hypothesis that was tested was that surfaces with higher albedo will increase the rate of mass loss. The second hypothesis was that a wild type Sorghum bicolor with higher lignin concentration will degrade more rapidly than a double mutant variety. Three different artificial surface covers (aluminum foil, black paint, and …
