Low densities and little change in water clarity characterize zebra mussel invasions near the southern extent of their range Open
Invasive species are often assumed to have measurable impacts throughout their potential range, but this is not always true. This study evaluated whether zebra mussels ( Dreissena polymorpha ) were causing an increase in water clarity near…

Performance of Urinalysis Parameters in Predicting Urinary Tract Infection: Does One Size Fit All? Open
In a multihospital cohort study of 3392 patients, positive urinalysis parameters had poor positive predictive value for diagnosing urinary tract infection (UTI). Combined urinalysis parameters (pyuria or nitrite) performed better than pyur…

Modest dispersal, low densities, and little change in water clarity characterize zebra mussel populations near the southern extent of their range Open
Invasive, filter feeding zebra mussels (Dreissena polymorpha) typically cause an increase in water clarity shortly after their establishment. The purpose of this study is to evaluate whether this occurred in Midwest reservoirs, near the so…

Under-ice and open-water ecosystem metabolism in temperate water bodies Open
Winter, historically a largely un-monitored season, is influential and changing. There is evidence of the importance of under-ice phytoplankton in temperate lakes, but it is currently unknown if high winter phytoplankton biomass translates…

Nonlinear multidecadal trends in organic matter dynamics in Midwest reservoirs are a function of variable hydroclimate Open
Dissolved organic matter (DOM) and particulate organic matter (POM) can influence biogeochemical processes in aquatic systems. An understanding, however, of the source, composition, and processes driving inland reservoir organic matter (OM…

Microcystin accumulation in Sportfish from an agricultural reservoir differs among feeding guild, tissue type, and time of sampling Open
Cyanobacterial blooms sometimes create secondary metabolites that can be transferred between trophic levels and accumulate in fish, but little is known about what time of year fish are most susceptible. Here, we examine microcystin in the …

Classifying Mixing Regimes in Ponds and Shallow Lakes Open
Lakes are classified by thermal mixing regimes, with shallow waterbodies historically categorized as continuously mixing systems. Yet, recent studies demonstrate extended summertime stratification in ponds, underscoring the need to reasses…

The role of organic nutrients in structuring freshwater phytoplankton communities in a rapidly changing world Open
Carbon, nitrogen, and phosphorus are critical macroelements in freshwater systems. Historically, researchers and managers have focused on inorganic forms, based on the premise that the organic pool was not available for direct uptake by ph…

Differences in ebullitive methane release from small, shallow ponds present challenges for scaling Open
Small, shallow waterbodies are potentially important sites of greenhouse gas release to the atmosphere. The role of ebullition may be enhanced here relative to larger and deeper systems, due to their shallow water, but these features remai…

Quantifying greenhouse gas ebullition rates across varying land uses, sediment types, and water temperatures in wetland systems Open
Around the world, wetlands and other aquatic ecosystems release greenhouse gases (GHG) into the atmosphere. GHGs escape from these systems through the process of ebullition -- or bubbles being released from the aquatic sediments. Ebullitio…
