Evaluation Of Rapid Viability-Polymerase Chain Reaction (RV-PCR) For Bacillus Globigii Spores In Water Matrices

Rapid water-quality tests for microorganisms are needed to quickly ensure that water is safe for consumption. This study will test a rapid-viability, quantitative polymerase chain reaction (RV-PCR) method for the detection of Bacillus spores. The method will be tested in large-volume drinking water samples that are concentrated by ultrafiltration, as well as in water that has been disinfected...

Nutrients And Sediment In The Western Lake Erie Basin

Sediment and nutrient runoff (nitrogen and phosphorus) from agricultural and urban land-use practices are of great concern in the Western Lake Erie Basin watersheds. Excessive nutrient inputs can lead to algal blooms that deplete the oxygen available to aquatic plants and animals. The blooms may result in cyanotoxins or cause taste and odor problems to public water supplies.

Natural Background Methane In Ohio Aquifers: Occurrence, Isotopic Characteristics, And Relation To Arsenic Concentrations

Arsenic is odorless and tasteless and can enter drinking-water supplies from natural deposits in rock and soil. In some parts of Ohio, arsenic concentrations in groundwater have exceeded the arsenic drinking-water standard of 10 parts per billion that the U.S. Environmental Protection Agency has set to protect consumers from the effects of long-term, chronic exposure to arsenic(U.S....

Biodegradation Of Microcystins In Lake Erie Source Waters And Filters From Drinking-Water Plants

Harmful cyanobacterial “algal” blooms (cyanoHABs) and associated toxins, such as microcystin, are a major global water-quality issue.  In Lake Erie, researchers and local health officials have identified the presence of cyanobacterial blooms during the summer and early fall seasons. This is especially pronounced in the Lake Erie Western Basin, where the City of Toledo was forced to issue a do-...

Multidirectional abundance shifts among North American birds and the relative influence of multifaceted climate factors

Shifts in species distributions are major fingerprint of climate change. Examining changes in species abundance structures at a continental scale enables robust evaluation of climate change influences, but few studies have conducted these evaluations due to limited data and methodological constraints. In this study, we estimate temporal changes in...

Salt marsh loss affects tides and sediment budget in shallow bays

The current paradigm is that salt marshes and their important ecosystem services are threatened by global climate change; indeed, large marsh losses have been documented worldwide. Morphological changes associated with salt marsh erosion are expected to influence the hydrodynamics and sediment dynamics of coastal systems. Here the influence of...

A geostatistical state‐space model of animal densities for stream networks

Many statistical analyses of populations ignore potential autocorrelations and assume that survey methods (distance and time between samples) eliminate these correlations, allowing samples to...

Quantifying climate sensitivity and climate-driven change in North American amphibian communities

Variation in the vital rates of an Antarctic marine predator: the role of individual heterogeneity

Variation in life‐history traits such as lifespan and lifetime reproductive output is thought to arise, in part, due to among‐individual differences in the underlying probabilities of survival and reproduction. However, the stochastic nature of demographic processes can also generate considerable variation in fitness‐related traits among otherwise...

Deciphering the dynamics of inorganic carbon export from intertidal salt marshes using high-frequency measurements

The lateral export of carbon from coastal marshes via tidal exchange is a key component of the marsh carbon budget and coastal carbon cycles. However, the magnitude of this export has been difficult to accurately quantify due to complex tidal dynamics and seasonal cycling of carbon. In this study, we use in situ...
