Great Lakes Restoration Initiative

The Great Lakes Restoration Initiative (GLRI) was established in 2009 to accelerate efforts to protect and restore the Great Lakes. The USGS is collaborating with partners to provide science to meet GLRI Action Plan goals and inform resource management decisions.

Turbidity and estimated phosphorus retention in a reconnected Lake Erie coastal wetland

Nearly all of the wetlands in the coastal zone of Lake Erie have been degraded or destroyed since the 1860s, and most of those that remain are separated from their watersheds by earthen dikes. Hydrologic isolation of these wetlands disrupts ecosystem benefits typical to Great Lakes coastal wetlands, particularly the ability to trap sediments and retain nutrients when inundated by runoff and lake w

Histochemical evidence for nitrogen‐transfer Endosymbiosis in non‐photosynthetic cells of leaves and inflorescence bracts of angiosperms

We used light and confocal microscopy to visualize bacteria in leaf and bract cells of more than 30 species in 18 families of seed plants. Through histochemical analysis, we detected hormones (including ethylene and nitric oxide), superoxide, and nitrogenous chemicals (including nitric oxide and nitrate) around bacteria within plant cells. Bacteria were observed in epidermal cells, various filamen

Fungal endophyte effects on invasive Phragmites australis performance in field and growth chamber environments

Manipulating plant microbiomes may provide control of invasive species. Invasive Phragmites australis has spread rapidly in North American wetlands, causing significant declines in native biodiversity. To test microbiome effects on host growth, we inoculated four common fungal endophytes into replicated Phragmites genotypes and monitored their growth in field and growth chamber environments. Inocu

Assessing stormwater reduction through green infrastructure: RecoveryPark (Detroit, Mich.)

The effectiveness of green infrastructure (including urban land conversion and bioswales) at reducing stormwater runoff is being assessed at RecoveryPark, a redeveloped urban farm in Detroit, Michigan. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, precipitation, and potential evapotranspiration (ET) to evaluate stormwater-volume reduction in response to...

Assessing stormwater reduction using green infrastructure: Gary City Hall (Gary, Ind.)

The effectiveness of green infrastructure (rain gardens and decreased impervious surface) at reducing stormwater runoff and capturing dissolved chloride is being assessed at a redevelopment project at Gary City Hall (Gary, Indiana). This study will evaluate pre- and post-construction hydrologic conditions using data collected by monitoring storm-sewer flow, groundwater levels, soil moisture, and...

Developing a Pre-Event Planning Tool for Modified Unified Method Fishing Events (Web Application)

The USGS is adapting the Chinese Unified Method, a fishing harvest method that uses herding techniques and a variety of nets to drive fish and concentrate them into a concentrated area for capture, in the fight against invasive Asian carps. This “Modified Unified Method” incorporates adapted techniques and modern technology for efficient, mass removal of bigheaded carp in North American waters...
