Abundance of Planktonic Virus-Like Particles in Lake Erie Subsurface Waters

Microbial Distributions and the Impact of Phosphorus on Bacterial Activity in Lake Erie

In light of recent suggestions concerning the relaxation of controls on phosphorus loading in Lake Erie, and in consideration of our current lack of baseline information on microbial communities in this system, a two-part analysis of the microbial ecology of the lake has been conducted. A comprehensive survey of the surface waters collected data on phytoplankton abundance, bacterial productivit...

Dynamics of various viral groups infecting autotrophic plankton in Lake Geneva

Viral community structure and dynamics were investigated for the first time in surface waters (0–20m) of Lake Geneva over a 5-month period between July and November 2011. Abundances of autotrophic picoplankton, heterotrophic bacteria and virus-like particles determined using flow cytometry revealed their predominance during the summer months followed by a slight decrease in fall. Two groups of ...

Abundance and Diversity of Ammonia-Oxidizing Archaea and Bacteria in Sediments of Trophic End Members of the Laurentian Great Lakes, Erie and Superior

Ammonia oxidation is the first step of nitrification carried out by ammonia-oxidizing Archaea (AOA) and Bacteria (AOB). Lake Superior and Erie are part of the Great Lakes system differing in trophic status with Lake Superior being oligotrophic and Lake Erie meso- to eutrophic. Sediment samples were collected from both lakes and used to characterize abundance and diversity of AOA and AOB based o...

Evaluation of Regression Approaches for Predicting Yellow Perch (Perca flavescens) Recreational Harvest in Ohio Waters of Lake Erie

Arcobacter in Lake Erie beach waters: an emerging gastrointestinal pathogen linked with human-associated fecal contamination.

The genus Arcobacter has been associated with human illness and fecal contamination by humans and animals. To better characterize the health risk posed by this emerging waterborne pathogen, we investigated the occurrence of Arcobacter spp. in Lake Erie beach waters. During the summer of 2010, water samples were collected 35 times from the Euclid, Villa Angela, and Headlands (East and West) beac...
