Artificial neural networks (ANNs) and Bayesian belief networks (BBNs) utilizing select environmental variables were developed and evaluated, with the intent to model net ecosystem metabolism (a proxy for system trophic state) within a freshwater wetland. Network modeling was completed independently for distinct data subsets, representing periods of 'low'(More)
Invasive common reed (Phragmites australis) can rapidly form expansive, near-monotypic stands, and thereby lower plant diversity and change marsh habitat structure. Consequently, North American wetland managers often use herbicides, such as glyphosate-based AquaNeat® and imazypr-based Habitat®, to control its establishment and spread. However, herbiciding(More)
We recently published an experimental study done in a Lake Erie coastal marsh in which 15 20 9 20 m plots of invasive Phragmites australis (common reed) were treated with either a 30 % solution of the glyphosate herbicide AquaNeatÒ, a 5 % solution of the imazapyr-based herbicide HabitatÒ, or left herbicide-free (n = 5 for each treatment) (Back et al. 2012).(More)
