The Stability Of Temperate Lakes Under The Changing Climate, Aleksey Paltsev
The Stability Of Temperate Lakes Under The Changing Climate, Aleksey Paltsev
Electronic Thesis and Dissertation Repository
There is a collective prediction among ecologists that climate change will enhance phytoplankton biomass in temperate lakes. Yet there is noteworthy variation in the structure and regulating functions of lakes to make this statement challengeable and, perhaps, inaccurate. To generate a common understanding on the trophic transition of lakes, I examined the interactive effects of climate change and landscape properties on phytoplankton biomass in 12,644 lakes located in relatively intact forested landscapes. Chlorophyll-a (Chl-a) concentration was used as a proxy for phytoplankton biomass. Chl-a concentration was obtained via analyzing Landsat satellite imagery data over a 28-year period (1984-2011) and using …

Natural disturbances such as fires and severe storms can have profound impacts on the hydrology and ecology of inland waters, potentially altering the structure and function of the ecosystem for extended periods of time. Studies of the initial impacts are, however, uncommon. Here we report on the short-term impacts of Hurricane Irma in the structure of the phytoplankton association in Lake Louise, a small blackwater lake in southern Georgia. Irma hit the region on September 11, 2017, with tropical storm force winds. The event corresponded to a period during which we were conducting routine weekly monitoring of environmental conditions in …
Effects Of Invasive Watermilfoil And Seasonal Dynamics On Primary Production In Littoral Zones Of North-Temperate Lakes, Ryan R. Van Goethem
Effects Of Invasive Watermilfoil And Seasonal Dynamics On Primary Production In Littoral Zones Of North-Temperate Lakes, Ryan R. Van Goethem
Dissertations, Master's Theses and Master's Reports
Climate change and species invasion are two agents of global change altering aquatic ecosystems worldwide. Submerged aquatic macrophytes control lake ecosystem processes through their direct and indirect interactions with other primary producers, but how their interactions may be altered by species invasions or how they function over full seasonal cycles in temperate lakes is poorly understood. We first addressed whether the presence of invasive watermilfoil (IWM) altered standing crops and gross primary pro-duction (GPP) of other littoral primary producers (macrophytes, phytoplankton, attached algae or periphyton) in littoral zones of 6 Michigan lakes. We found no differences in primary producer standing …
