Transport And Fate Of Phosphorus In The Nearshore Zone Of Lake Michigan, Nathan Van Ee
Transport And Fate Of Phosphorus In The Nearshore Zone Of Lake Michigan, Nathan Van Ee
Theses and Dissertations
Bioavailable phosphorus loads exported to Lake Michigan from the Milwaukee and Sheboygan River Watersheds appear to have increased in the last 40 years despite meeting total phosphorus (TP) loading goals set by the Great Lakes Water Quality Agreement (GLWQA).Overall, bioavailability of P delivered from the Milwaukee and Sheboygan Rivers was highest during the warmer months, which coincides with the nearshore nuisance algae growth season. However, first order loss rates of SRP calculated during baseflow recession were also greatest during the summer, suggesting that increased river residence time during the summer could reduce export of bioavailable P. Observations of phosphorus partitioning …
Autumn Tree Phenology In Northern Wisconsin: Humans Versus Photographs, Trevor Iglinski
Autumn Tree Phenology In Northern Wisconsin: Humans Versus Photographs, Trevor Iglinski
Theses and Dissertations
Ecosystem primary productivity halts when plants go dormant, and so the timing of dormancy as it relates to autumn phenology has been a focus of much interdisciplinary research. While monitoring plant phenology has its roots in directly observing specimens, digital sensors along with modern methods have also become a mainstay in phenology. Results from different methods often vary, so there is still a need to better understand how digital cameras record autumn phenology, especially in comparison with ground-based observations (Keenan et al. 2014). This study compared autumn phenology derived from direct ground observations with upward-facing fisheye photography, in the context …
