Forecasting the combined effects of anticipated climate change and agricultural conservation practices on fish recruitment dynamics in Lake Erie

David A. Dippold, Noel R. Aloysius, Steven Conor Keitzer, Haw Yen, more

Freshwater Biology > 65 > 9 > 1487 - 1508

Many aquatic ecosystems are experiencing multiple anthropogenic stressors that threaten their ability to support ecologically and economically important fish species. Two of the most ubiquitous stressors are climate change and non‐point source nutrient pollution. Agricultural conservation practices (ACPs, i.e. farming practices that reduce runoff, prevent erosion, and curb excessive nutrient loading)...

Modeling nutrient removal using watershed-scale implementation of the two-stage ditch

Sheila F. Christopher, Jennifer L. Tank, Ursula H. Mahl, Haw Yen, more

Ecological Engineering > 2017 > 108 > PB > 358-369

Western Lake Erie Basin (WLEB) is the most intensively farmed region of the Great Lakes. Because of the flat topography and poorly-drained soils many farmers rely on drainage management practices (e.g., subsurface tile drainage, ditch channelization) to maintain productive agriculture. However, these practices also facilitate the delivery of excess nutrients and sediments to Lake Erie, which have...

Hydrogen peroxide‐dependent antibacterial action of Melilotus albus honey

P. Sowa, D. Grabek‐Lejko, M. Wesołowska, S. Swacha, more

Letters in Applied Microbiology > 65 > 1 > 82 - 89

Honey originating from different floral sources exhibits the broad spectrum of antibacterial activity as a result of the presence of hydrogen peroxide as well as nonperoxide bioactive compounds. The mechanisms of antibacterial activity of Polish melilot honey were investigated for the first time. Polish melilot honey samples (Melilotus albus biennial = 3 and annual = 5, Melilotus officinalis = 1)...

Annexin A10 optimally differentiates between intrahepatic cholangiocarcinoma and hepatic metastases of pancreatic ductal adenocarcinoma: a comparative study of immunohistochemical markers and panels

Julia Kälsch, Juliet Padden, Stefanie Bertram, Leona L. Pott, more

Virchows Archiv > 2017 > 470 > 5 > 537-543

Discriminating intrahepatic cholangiocarcinoma (ICC) from hepatic metastases of pancreatic ductal adenocarcinoma (mPDAC) can be challenging. While pathologists might depend on clinical information regarding a primary tumor, their diagnosis will lead the patient either to potentially curative surgery (for ICC) or to palliation (for mPDAC). Beyond the validation of recently published potential biomarkers...

Reducing current and future risks: Using climate change scenarios to test an agricultural conservation framework

Kimberly R. Hall, Matthew E. Herbert, Scott P. Sowa, Sagar Mysorekar, more

Journal of Great Lakes Research > 2017 > 43 > 1 > 59-68

Evaluating the potential effects of changes in climate on conservation practices can help inform strategies to protect freshwater biodiversity that are robust, even as conditions change. Here we apply a climate change “test” to a framework for estimating the amount of agricultural conservation practices needed to achieve desired fish conservation outcomes for four watersheds in the Saginaw Bay region...

A synthesis and comparative evaluation of factors influencing the effectiveness of drainage water management

Jared A. Ross, Matthew E. Herbert, Scott P. Sowa, Jane R. Frankenberger, more

Agricultural Water Management > 2016 > 178 > C > 366-376

Viable large-scale crop production in the United States requires artificial drainage in humid and poorly drained agricultural regions. Excess water removal is generally achieved by installing tile drains that export water to open ditches that eventually flow into streams. Drainage water management (DWM) is a conservation practice that allows farmers to artificially raise the outlet elevation of a...

Making the leap from science to implementation: Strategic agricultural conservation in Michigan's Saginaw Bay watershed

Mary Fales, Randal Dell, Matthew E. Herbert, Scott P. Sowa, more

Journal of Great Lakes Research > 2016 > 42 > 6 > 1372-1385

There is growing evidence that addressing nonpoint source pollution within intensely agricultural regions of the Great Lakes will require innovative solutions to achieve meaningful ecological outcomes. Recognizing this, a broad coalition of partners is collaborating across Michigan's Saginaw Bay watershed to develop and test innovative approaches to achieve the vision of Strategic Agricultural Conservation...

Sustainable management of Great Lakes watersheds dominated by agricultural land use

John M. Kerr, Joseph V. DePinto, Dennis McGrath, Scott P. Sowa, more

Journal of Great Lakes Research > 2016 > 42 > 6 > 1252-1259

Runoff of agricultural nutrients and sediments has led to re-eutrophication of lakes and impaired stream health in the Great Lakes Basin since around 2000 following earlier success in protecting water quality. Substantial investment in conservation actions has had insufficient impact, due in part to a limited basis for understanding the likely environmental outcomes of those investments. This article...

How much conservation is enough? Defining implementation goals for healthy fish communities in agricultural rivers

Scott P. Sowa, Matthew Herbert, Sagar Mysorekar, Gust M. Annis, more

Journal of Great Lakes Research > 2016 > 42 > 6 > 1302-1321

“How much conservation is enough?” is one of the most important and difficult questions to answer. In this work, we demonstrate an approach to specifically answer this question for conservation strategies designed to address nonpoint source pollution in agriculturally-dominated watersheds. We developed empirical models relating conservation investments and actions to measures of stream water quality...

Thinking outside of the lake: Can controls on nutrient inputs into Lake Erie benefit stream conservation in its watershed?

S. Conor Keitzer, Stuart A. Ludsin, Scott P. Sowa, Gust Annis, more

Journal of Great Lakes Research > 2016 > 42 > 6 > 1322-1331

Investment in agricultural conservation practices (CPs) to address Lake Erie's re-eutrophication may offer benefits that extend beyond the lake, such as improved habitat conditions for fish communities throughout the watershed. If such conditions are not explicitly considered in Lake Erie nutrient management strategies, however, this opportunity might be missed. Herein, we quantify the potential for...

A new simple method for assessing security of low-voltage power networks development variants

A. Halinka, P. Rzepka, P. Sowa, M. Szablicki

Przegląd Elektrotechniczny > 2016 > R. 92, nr 11 > 287--291

This paper presents a new and simple expert method for assessment of potential development variants of LV power networks. The network security, dispatching personnel and power consumers were taken into consideration. The uniqueness of the method is its ease of use. Each variant was evaluated using 20 indicators. These indicators are defined clearly and concern the narrow-themed aspects of security...

Science of The Total Environment > 2016 > 569-570 > C > 1265-1281

Complex watershed simulation models are powerful tools that can help scientists and policy-makers address challenging topics, such as land use management and water security. In the Western Lake Erie Basin (WLEB), complex hydrological models have been applied at various scales to help describe relationships between land use and water, nutrient, and sediment dynamics. This manuscript evaluated the capacity...

Ways of Improving the Reliability of Supply of Selected Important Municipal Customers in Municipalities

B. Mól, P. Sowa, J. Bargiel

Acta Energetica > 2016 > nr 1 > 93--97

This paper reviews the most important ways to improve the reliability of supply of consumers, i.e. the increase in the number of directions of supply, use of grid and system automatic controls, and installation of distributed generation sources. The order of priority of municipal loads in terms of electricity and heat supply continuity is then analysed. The concept of so-called energy mini centres...
