Characterization of Microplastics and 6-PPD Quinone in a Suburban Lake–Tributary System Impacted by Highway Runoff Open
Characterizing and enumerating microplastics (MPs) have received considerable attention in recent years. Most attention has focused on major waterways and especially in the water column. However, less is known about MPs in smaller lakes an…

Homeostatic response of calcium and potassium ions in Microcystis spp. and Chlorella to MC-LR Open
Cyanobacteria and green microalgae often co-exist during toxic algal blooms, but the influence of microcystins (MCs) on ionic homeostasis of these algae is not well-studied. This study used non-invasive micro-test technology to examine eff…

Phosphorus loading in impaired wetlands: The role of temperature and simulated dredging under controlled experimental conditions Open
Restoring wetlands can increase biodiversity and water quality in both wetlands and connecting ecosystems; however, failing to consider past land uses can result in negative water quality effects. Prior agricultural practices at a coastal …

Changes in Cyanobacterial Phytoplankton Communities in Lake-Water Mesocosms Treated with Either Glucose or Hydrogen Peroxide Open
When cyanobacterial phytoplankton form harmful cyanobacterial blooms (HCBs), the toxins they produce threaten freshwater ecosystems. Hydrogen peroxide is often used to control HCBs, but it is broadly toxic and dangerous to handle. Previous…

Ecological status of a retired mine lake in a protected dune ecosystem Open
Ottawa Sands Lake (OSL) is a retired mine lake located in a protected dune ecosystem adjacent to Lake Michigan in west Michigan, USA. Development activities are planned for the lake and surrounding land, potentially threatening the lake's …

Periodic Addition of Glucose Suppressed Cyanobacterial Abundance in Additive Lake Water Samples during the Entire Bloom Season Open
Previously, we showed that prophylactic addition of glucose to Harsha Lake water samples could inhibit cyanobacteria growth, at least for a short period of time. The current study tested cyanobacterial control with glucose for the entire H…

Land cover and water quality of drowned river mouths: Evidence of an environmental gradient along the eastern Lake Michigan shoreline Open
Lake Michigan's drowned river mouths (DRM) are hydrologically unique systems with both riverine and large-lake influences. Serving as focal points for human development, DRMs have experienced a history of industrialization, urbanization, a…

Urban lake water quality responses to elevated road salt concentrations Open
Road salt runoff from de-icing applications is increasingly impacting water quality around the globe. Excess salt (especially chloride) concentrations can negatively impact the biological, chemical, and physical properties of freshwater ec…

Chloride and phosphorus retention and release in soils surrounding a salt-contaminated lake in West Michigan Open
Salinization in freshwater ecosystems has become an increasingly prevalent issue. Past studies indicate that increased salinity levels in lakes can impact biota, stimulate internal nutrient loading, and prevent seasonal turnover, potential…

Wetland Restoration through Excavation: Sediment Removal Results in Dramatic Water Quality Improvement Open
We evaluated whether sediment excavation improved water quality in a former (pre-European settlement) wetland complex that was a farm in the early 1900s and then later in the 1990s/early 2000s was allowed to naturally refill with water and…

Reduction of Phosphorus Using Electric Arc Furnace Slag Filters in the Macatawa Watershed (Michigan) Open
Eutrophication is a major problem in lakes and rivers throughout the world. One such system is Lake Macatawa, located in West Michigan, which hydrologically connects to Lake Michigan. Lake Macatawa and its watershed suffer from excess phos…

Groundwater in Crisis? Addressing Groundwater Challenges in Michigan (USA) as a Template for the Great Lakes Open
Groundwater historically has been a critical but understudied, underfunded, and underappreciated natural resource, although recent challenges associated with both groundwater quantity and quality have raised its profile. This is particular…

Significant Temporal and Spatial Variability in Nutrient Concentrations in a Chinese Eutrophic Shallow Lake and Its Major Tributaries Open
Sediment nutrients can be released to the surface water when hydraulic disturbance becomes strong in shallow lakes, which contributes to nutrient enrichment and subsequent lake eutrophication in the water column. To explore the seasonal va…

Perfluoroalkylated Substances (PFAS) Associated with Microplastics in a Lake Environment Open
The presence of both microplastics and per- and polyfluoroalkyl substances (PFAS) is ubiquitous in the environment. The ecological impacts associated with their presence are still poorly understood, however, these contaminants are extremel…

Contrasting trajectories in macrophyte community development after shoreline restoration: water level obscures trends Open
Macrophytes are critical components of biologically productive lake littoral zones. Sensitivity to environmental factors such as sediment content and light availability makes macrophytes potential bioindicators of anthropogenic stress. The…
