TLDR
In this article, the authors consider how invasive dreissenid mussels affect ecosystem stability processes in Lake Erie through both consumptive and excretory processes using the stability landscape heuristic.Abstract:
Ecosystem stability processes such as constancy, resilience and persistence are important, but often neglected, topics of invasive species research. Here we consider how invasive dreissenid mussels affect ecosystem stability processes in Lake Erie through both consumptive and excretory processes using the stability landscape heuristic (Gunderson, 2000). Consumption of phytoplankton by dreissenid mussels adds complexity to the system and potentially slows energy transfer from lower to higher trophic levels decreasing system constancy and lowering system resiliency. Excreting soluble waste products at low nitrogen to phosphorus ratios exacerbates these impacts on stability processes because low nutrient ratios favor growth of cyanobacterial blooms, less preferred food of zooplankton, further decreasing the transfer of energy from lower to higher trophic levels. We also provide evidence for recent changes in Lake Erie's stability landscape including a return towards eutrophy.read more

TL;DR: It is shown that long-term trends in agricultural practices are consistent with increasing phosphorus loading to the western basin of the lake, and that these trends, coupled with meteorological conditions in spring 2011, produced record-breaking nutrient loads.

Soluble nitrogen and phosphorus excretion of exotic freshwater mussels (Dreissena spp.): potential impacts for nutrient remineralisation in western Lake Erie
Joseph D. Conroy,William J. Edwards,Ruth Atkins Pontius,Douglas D. Kane,Hongyan Zhang,John F. Shea,Julie N. Richey,David A. Culver +7 more
TL;DR: Comparing dreissenid ammonia and phosphate excretion with that of the crustacean zooplankton, it is demonstrated that the mussels add to nitrogen and phosphorus remineralisation, shortening nitrogen and phosphate turnover times, and, importantly, modify thenitrogen and phosphorus cycles in Lake Erie.

Effects of Increasing Nitrogen and Phosphorus Concentrations on Phytoplankton Community Growth and Toxicity During Planktothrix Blooms in Sandusky Bay, Lake Erie
TL;DR: The results suggest that as best management practices are developed for P reductions in Sandusky Bay, managers must be aware of the negative implications of not managing N loading into this system as N may significantly impact cyanobacterial bloom size and toxicity.

Temporal Trends in Lake Erie Plankton Biomass: Roles of External Phosphorus Loading and Dreissenid Mussels
Joseph D. Conroy,Douglas D. Kane,David M. Dolan,William J. Edwards,Murray N. Charlton,David A. Culver +5 more
TL;DR: The results of lakewide plankton studies conducted during 1996-2002 with data reported in the literature from previous years to evaluate the effectiveness of continued nutrient control, the relationship between external phosphorus loading and plankton abundance, and the many predicted outcomes of the dreissenid invasion.

Challenges in tracking harmful algal blooms: A synthesis of evidence from Lake Erie
TL;DR: The authors explore the state of the science in answering these basic questions; they use Lake Erie as a case study, where nearly two decades after the resurgence of HABs, a summer 2014 event caused a mandatory three day tap water ban for Toledo, Ohio.

TL;DR: The traditional view of natural systems, therefore, might well be less a meaningful reality than a perceptual convenience.

TL;DR: In this article, the introduction of invasive species and identifying life history stages where management will be most effective are discussed. And evolutionary processes may be key features in determining whether invasive species establish and spread.
