Full textAbstract:
Phytophthora root rot of soybean, caused by Phytophthora sojae, is one of the most important diseases in the Midwestern United States, and is estimated to cause losses of up to 1.2 million metric tons per year. Disease may also be caused by P. sansomeana; however, the prevalence and damage caused by this species is not well known, partly due to limitations of current diagnostic tools. Efficient, accurate, and sensitive detection of pathogens is crucial for management. Thus, multiplex qPCR and isothermal RPA (recombinase polymerase amplification) assays were developed using a hierarchical approach to detect these Phytophthora spp. The assays consist of a genus-specific probe and two species-specific probes that target the atp9-nad9 region of the mitochondrial genome that is highly specific for the genus Phytophthora. The qPCR approach multiplexes the three probes and a plant internal control. The RPA assays run each probe independently with a plant internal control multiplexed in one amplification, obtaining a result in as little as 20 mins. The multicopy mitochondrial genome provides sensitivity with sufficient variability to discern among different Phytophthora spp. The assays were highly specific when tested against a panel of 100 Phytophthora taxa and range of Pythium spp. The consistent detection level of the assay was 100 fg for the qPCR assay and 10 pg for the RPA assay. The assays were validated on symptomatic plants collected from Michigan (U.S.) and Ontario (Canada) during the 2013 field season, showing correlation with isolation. In 2014, the assays were validated with samples from nine soybean producing states in the U.S. The assays are valuable diagnostic tools for detection of Phytophthora spp. affecting soybean.

Full textAbstract:
Sub-Saharan African migration to the U.S. is rapidly yet quietly growing, and the Midwestern/Great Lakes region of the country (its “Third Coast”) is becoming an increasingly important destination. In particular, the so-called “Second City” of Chicago – the regional epicenter and third largest U.S. city – is in need of social scientific research addressing the unique trajectories and experiences of its expanding African populations. This paper provides a background for these dynamics by drawing from primary and secondary data on Midwestern African migrant communities’ organizing and activities as observed through interviews and fieldwork among more than fifty African migrant organizations in the Midwestern U.S. and Greater Chicago Metropolitan Area. It will outline the evolution and distribution of African migration in the Chicago area and provide a brief overview of African resources, organizations, and other institutions and establishments as they seek to bring together and represent the burgeoning African community within and beyond the city.

Full textAbstract:
AbstractHalyomorpha halys (Stål) (Hemiptera: Pentatomidae), also known as the brown marmorated stink bug, is an invasive agricultural and nuisance pest. Knowledge of the life history of insect pests is important for informing pest management activities. Some North American populations of H. halys have two generations per year, and it is suspected that H. halys may have a partial second generation in the Niagara Region of Ontario, Canada. We determined the number of H. halys generations in Ontario by examining the reproductive development of field-caught adult females. The pattern of reproductive development we observed supports the conclusion that H. halys complete one generation per year in the Niagara Region of Ontario. Reproductively active H. halys were captured as early as May and continued until early September, and the peak of reproductively active individuals occurred between 250 and 550 degree days calculated with a sine-wave function and a lower threshold set to 14.17 °C.

Full textAbstract:
AbstractWhat scientists include among the essential attributes of sustainable agricultural systems can influence the development of agricultural research agendas and how research is done. Current perspectives on sustainability place varying emphasis on environmental and agrarian values and propose different amounts and kinds of change in agricultural production, agricultural science, and rural social institutions. In a delphi study, agricultural scientists at North Central region land-grant universities considered environmental management and development of new farming technologies as essential to a definition of sustainable agriculture, but gave little importance to social or scientific restructuring. With some qualifications, we characterize their view of sustainability as a stewardship perspective that does not include social considerations and explicitly rejects radical social change.

Full textAbstract:
ABSTRACTLyme disease, caused by the bacteriumBorrelia burgdorferisensu stricto, is an emerging zoonotic disease in Canada and is vectored by the blacklegged tick,Ixodes scapularis. Here we used Bayesian analyses of sequence types (STs), determined by multilocus sequence typing (MLST), to investigate the phylogeography ofB. burgdorferipopulations in southern Canada and the United States by analyzing MLST data from 564B. burgdorferi-positive samples collected during surveillance. A total of 107 Canadian samples from field sites were characterized as part of this study, and these data were combined with existing MLST data for samples from the United States and Canada. Only 17% of STs were common between both countries, while 49% occurred only in the United States, and 34% occurred only in Canada. However, STs in southeastern Ontario and southwestern Quebec were typically identical to those in the northeastern United States, suggesting a recent introduction into this region from the United States. In contrast, STs in other locations in Canada (the Maritimes; Long Point, Ontario; and southeastern Manitoba) were frequently unique to those locations but were putative descendants of STs previously found in the United States. The picture in Canada is consistent with relatively recent introductions from multiple refugial populations in the United States. These data thus point to a geographic pattern of populations ofB. burgdorferiin North America that may be more complex than simply comprising northeastern, midwestern, and Californian groups. We speculate that this reflects the complex ecology and spatial distribution of key reservoir hosts.

Full textAbstract:
Abstract Lake-effect snowstorms are an important source of severe winter weather over the Great Lakes region and are often triggered by the passage of synoptic-scale low pressure systems. In this paper, a climatology of lake-effect snowstorms over southern Ontario, Canada, for the period 1992–99 is developed. The distinguishing characteristics of the synoptic-scale environment associated with intense lake-effect snowstorms in the region are identified through the study of individual events and through composite analysis. In particular, it is found that a low pressure and a cold-temperature anomaly situated over Hudson Bay, north of the Great Lakes, is a favorable environment for the development of intense lake-effect snowstorms over southern Ontario. It is also found that the track of the low pressure system can have a significant impact on the development or lack thereof of lake-effect snowstorms over southern Ontario. It is found that the low pressure systems that trigger intense lake-effect snowstorms tend to have an anomalous northeastward track as compared to the eastward track of most low pressure systems that transit the region.

Full textAbstract:
Government agenda setting has been a focus of research in the field of policy sciences for over two decades. The concept of a policy window is explored as a driver of governmental agenda setting. The Regional Municipality of York, Ontario, Canada was chosen as a case study for exploring the application of strategic environmental assessment at the municipal level through a policy window lens. Problem, policy and political streams converged to provide the necessary conditions for improved environmental assessment and infrastructure planning in York Region. A focusing event and the resulting crisis motivated stakeholders to identify and act on the problem. An SEA-type approach was initiated as one key response. A variety of activities were initiated by York Region including the development of a Sustainability Strategy, synchronisation of master planning, wider consideration of alternatives at the master plan level and improved public consultation. Conclusions are drawn and several recommendations are presented and discussed.

Full textAbstract:
The phytogeographic patterns displayed by the 550 rare vascular plant taxa in Ontario, including 349 that are rare nationally, are correlated with counties, site regions, and floristic provinces. Rare taxa are concentrated in southwestern Ontario decreasing northward, with secondary concentrations along the Hudson Bay coast. Rare taxa in Ontario are predominantly peripheral taxa, which have their main ranges outside of Ontario. Many of these taxa, however, have a high Canadian conservation priority because they are also at risk in adjacent states or provinces. Rare taxa with Appalachian and Coastal Plain affinities are most common in southwestern Ontario. Arctic and boreal affinities predominate in Northern Ontario. These patterns are correlated with temperature and moisture parameters, which are incorporated with the Hills' site regions classification. Most high conservation priority taxa occur in the Carolinian region, the most highly settled and most highly agriculturalized part of the province. There is an urgent need for conservation of the remaining forest and wetlands in this region. The fragmentary ecosystems still remaining must be protected from further development. There is a need to study the correlation of rare plant occurrences with existing parks and reserves throughout the province to facilitate the identification of priority regions for protection. Key words: rare plants, phytogeography, conservation, Ontario.

Full textAbstract:
Wealth and asset holding in late-nineteenth-century Ontario are examined using a new data set of census-linked probated decedents. Hump-shaped wealth-age profiles are found, supporting the importance of demographic and life cycle forces in late-nineteenth-century financial asset accumulation. With financial asset holding more pronounced in Ontario than Quebec, the implication for Canadian economic development is that the differences in capital formation and industrialization across Ontario and Quebec are partly rooted in saving behavior. The results show that urbanization, occupational status, literacy, the number of children, and region of residence are important determinants of wealth and asset holding.

Full textAbstract:
This research analyzed declining resource-based communities in the Rainy River District, Ontario, that is typical of the Canadian middle north, and explored their central features using several qualitative and participatory techniques. This work disengages from traditional demographic-economic analysis of decline and offers an alternative multidimensional interpretation. The analysis centers on the role of networks, diverse forms of capitals and conflicts. Literature on regional development, New Regionalism, social networks, capital, conflict, and complex evolving social systems informed the conceptual framework to guiding this research. Among other findings this research demonstrated that: First, economic-demographic “size type” indicators are insufficient to explain the complex, multidimensional, network-based, conflictive and highly politicized nature of decline. Policies based on these type of indicators are misleading and can reinforce the path dependence process of single-industry rural communities. Second, networks, capital and conflicts can be significant in the process of decline. They can speed or slow the process of change. Potentially, they can be transformed and used when planning for decline so as to steer the process toward sustainable rural planning and development. Additional factors identified and proposed for this framework included: learning, interaction, cooperation, connectivity, and psychological and institutional factors restricting rural communities from reacting to decline, and escaping from path dependence. Third, decline should be recognized in order to start a process of planning for decline and rural development. Top-down planning and policy initiatives in the Rainy River District and across North Western Ontario have not recognized a general planning gap and have glossed over the need to approach decline, and rural development generally, using a local perspective and grassroots initiatives of people and communities. Basic elements to plan for decline in rural regions were described. Fourth, rural regions, ethnicity, and power, are insufficiently recognized by New Regionalism theory. Including these elements can benefit the theory and practice of rural planning and development. Analysis of networks and planning is a mutually reinforcing approach, useful for the study and planning of rural areas. Finally, rural decline studies in Canada should pay attention to factors of ethnicity. Significant structural violence against First Nations remains in rural regions.

Full textAbstract:
A History of the Ozarks, Vol. 2: The Conflicted Ozarks focuses on the long era of Civil War and Reconstruction, stretching roughly from the 1850s through the 1880s. The book begins with an analysis of slavery (the most thorough examination of the institution in the region to date) and the secession crisis. Almost half the book deals with the four years of civil warfare, including a summary of the formal, battlefield war in the Ozarks and an examination of various facets of the home front, from guerrilla fighters to the role of women. It also features the most comprehensive portrait of the long Reconstruction era in the Ozarks, including a comparison of political Reconstruction in Arkansas and Missouri as well as an extended treatment of social and economic reconstruction that chronicles railroad building, manufacturing, extractive industry, and the development of educational institutions in the postwar years. In addition to the continuation of volume 1’s argument that the story of the Ozarks is mostly an unexceptional, regional variation of the American story, volume 2 is built on the thematic concept of multiple layers of conflict in the region--divisions over slavery, wartime violence and its stubborn continuation in the Reconstruction era, and the continuing conflicted identity of the Ozarks as part southern and part midwestern, part Union and part Confederate, part modern and part backwoods.

<em>Abstract.</em>—Assessments of stream fish or benthos assemblages normally involve a contrast of conditions at test sites to conditions represented by regional reference sites that are either minimally or least disturbed. Identification of reference sites is difficult and normally involves a variety of subjective criteria. The development of reference models for stream fish and benthos in the Canadian tributaries of Lake Ontario is particularly challenging because there are few undeveloped areas and there is no consensus on criteria for a least-disturbed condition. Rather than identify sites as representing a least-disturbed condition, we developed a series of models that relate the existing biophysical condition of streams (i.e., the fish, benthos, and instream habitat) to landscape (i.e., slope, geology, catchment area) and land use/land cover (percent impervious cover [PIC]). Relationships between indices of biophysical condition and PIC can be used to hindcast or estimate the expected biophysical condition at a variety of land cover scenarios. The models cannot be used to predict conditions outside the calibration data range, but this approach does allow us to make use of a disturbance gradient and make predictions with a minimal number of least-disturbed sites. The difference between the hindcast reference and present day conditions is an estimate of present-day impacts. Results from this exercise provided an estimate of the magnitude of impairment of streams in the Canadian portion of the Lake Ontario region.

<em>Abstract.</em>—Jurisdictional boundaries add a layer of complexity to the already difficult task of managing fisheries. This paper outlines the challenges of cross-border management in the Great Lakes of North America and the Arctic-Yukon-Kuskokwim (AYK) region of Alaska and Yukon Territory and discusses the role of governance regimes established to facilitate fishery management in those regions. Management of the multi-jurisdictional Great Lakes fishery occurs without direct federal oversight. Eight Great Lakes states, the province of Ontario, and several U.S. tribes manage the sport, commercial, and subsistence fisheries within their jurisdiction, though the Canadian and U.S. federal governments make important contributions as well. To help in the development of shared fishery policies, the nonfederal jurisdictions, with the support of the federal agencies and the binational Great Lakes Fishery Commission, signed <em>A Joint Strategic Plan for Management of Great Lakes Fisheries</em>, a voluntary, consensus-based agreement. Similar to the Great Lakes, political diffusion is also a characteristic of management of salmon in the AYK region. AYK fishery management must consider state, federal, provincial, territorial, and international treaty jurisdictions. Different from the Great Lakes, federal involvement is much greater in the AYK region because of abundant federal lands combined with federal legislation (e.g., Alaska National Interest Lands Conservation Act of 1980) and the presence of international waters and treaties. Based on lessons from the Great Lakes, a pathway to increasing cooperation and effectiveness of AYK salmon management includes: identification of common interests; adoption of shared goals; information sharing; building of relationships among agencies and individuals; and use of consensus decision-making and accountability mechanisms. Connecting all of the agencies affecting the salmon life cycle and fisheries in the AYK region through an appropriate forum or institution would enhance cooperative and effective AYK salmon management.

Full textAbstract:
The North American Lake Superior region contains a world-class copper province nearly 300,000 km² in area. A dozen major copper deposits and hundreds of smaller mineral accumulations are located in Michigan, Minnesota, and Ontario (Morey and Sims 1996), many of which include As, nickel (Ni), platinum (Pt), palladium (Pd), Co, Mo, and Fe, as well as Cu (Nicholson et al. 1992). Historically, the province has hosted a variety of life forms; fossil biota have been traced as far back as 2.6-2.75 Ga. Palynological and microbial research (Robbins 1985, Robbins et al. 1994) prompts speculation about possible correlations between copper and the biota that evolved there. Because the region has been subjected to continental collisions, volcanism, glaciation, rifting, weathering, sea level rise and fall, waxing and waning of lakes, soil formation, and now to human settlement and development including mining, the fossil record is discontinuous. This review of the geologic formations in the Lake Superior region from the Precambrian to the present, and their copper and biotic occurrences and associations, attempts to illuminate some of those geologic/ biologic correlations, and includes mention of modern environmental concerns. Copper is one of nearly 75 chemical elements contributing to metabolic or structural functions of organisms (Dexter-Dyer et al. 1984). Bioassimilation varies and depends not only on availability from the environment, but also on the species, gender, and age of organism with specific concentrations also depending on diet, health, tissue assayed, and various synergisms with other trace elements such as Fe and Zn. Indeed, copper is an essential element and co-factor contributing to copper-associated polypeptides that provide catalytic and electron transfer functions in almost every known group of organisms alive today, from bacteria to humans. Copper proteins contribute to skin pigmentation, nerve coverings, and in mechanisms of development, maintenance, and repair of connective tissues important for well-functioning cardiovascular systems (Eisler 2000). Presently, over two dozen essential copper proteins, some with porphyrin-copper functional groups (similar to the porphyrin-iron association in hemoglobin), have been identified, each with its specific developmental or physiological function (Cowan 1998).

Abstract Public private partnership has played a mayor role in development and successful operation of the current KMS Peel Waste-to-Energy Plant located in Peel Region, Ontario. On December 10, 1998 KMS Peel Inc. and the Region of Peel entered into an agreement to expand the waste-to-energy facility by 36,000 tonnes (one additional incineration unit). Due to expansion, new, more stringent emission limits were imposed by the latest Ontario Ministry of Environment A-7 Guideline and the Canada-Wide Standards developed by Canadian Council of Ministers of Environment. A Selective Catalytic Reduction (SCR) system with a sodium tetrasulphide injection was selected to supplement the existing dry scrubber/fabric filter air pollution control system for additional reduction in mercury, nitrogen oxides and dioxins/furans emissions. With the upgraded air pollution control technology, the facility will be able to meet the latest emission standards and, to a certain degree, any new standards that may be enforced in future years. This paper outlines a partnership model that has been successfully implemented in Ontario and has contributed to the public accepting waste-to-energy as integral part of the waste management system, ultimately resulting in facility expansion. It also describes the current facility and upgrade to the existing air pollution control system.

The Regional Municipality of York is located immediately north of the City of Toronto. It is the fastest growing municipality in Ontario. The rapid expansion of residential, industrial and commercial development in the municipality has led to a weakness in the electrical and gas infrastructure. The Ontario Power Authority (the agency responsible for managing the power requirements in the Province of Ontario) has recognized this weakness and has developed plans calling for a new gas-fired generating station and improvements to the electrical grid. The shortages of gas supply and electricity have not developed overnight. Hydro One, which runs the electrical grid, initiated a supply study in 2002. The study recommended upgrading a 115 kV transmission line to a double circuit 230 kV transmission line on the existing corridor. The ensuing public outcry resulted in the municipality passing a resolution against the upgrade. Similarly, a large gas-fired generating station proposal was abandoned as the result of citizen opposition. In 2003, the Ontario Energy Board approved new Environmental Guidelines for the Location, Construction and Operation of Hydrocarbon Pipelines and Facilities in Ontario. The guidelines include specific new requirements for planning pipelines in urban areas. Among other things, these requirements involve the identification of indirectly affected landowners and a more detailed analysis of public issues and how they were resolved. It became clear that in order to achieve regulatory success, not only would the public have to become actively engaged in the decision-making early in the process, the technical reviewers (federal, provincial and municipal agencies) would likewise have to be actively involved. Through the use of two case studies of proposed large-diameter natural gas pipelines initiated in York Region in 2005, this paper describes the techniques used to engage the public and the regulators. It also describes how the public involvement requirements contained in the Ontario Energy Board’s new guidelines were incorporated into the planning process. The case studies begin with a rationale for the study area selected. A description of issues follows. The techniques used to address these issues and the success of the program are documented. Techniques include face-to-face project initiation meetings, use of technical and citizens’ advisory committees, sub-committee meetings to resolve specific issues and site-specific field work. The study results illustrate that it is possible to plan a right-of-way in such a manner as to satisfy the general public and regulators, be compatible with existing development, conform to the new Ontario Energy Board guidelines and minimize the amount of remedial work required to mitigate the impacts occurring on and adjacent to the right-of-way.

Full textAbstract:
A Deep Geologic Repository (DGR) for Low and Intermediate Level radioactive waste has been proposed by Ontario Power Generation for the Bruce Nuclear Power Development site in Ontario, Canada. The DGR is to be constructed at a depth of about 680 m below ground surface within the argillaceous Ordovician limestone of the Cobourg Formation. This paper describes a regional-scale geologic conceptual model for the DGR site and analyzes flow system evolution using the FRAC3DVS-OPG flow and transport model. This provides a framework for the assembly and integration of site-specific geoscientific data that explains and illustrates the factors that influence the predicted long-term performance of the geosphere barrier. In the geologic framework of the Province of Ontario, the Bruce DGR is located at the eastern edge of the Michigan Basin. Borehole logs covering Southern Ontario combined with site specific data have been used to define the structural contours at the regional and site scale of the 31 sedimentary strata that may be present above the Precambrian crystalline basement rock. The regional-scale domain encompasses an 18.500km2 region extending from Lake Huron to Georgian Bay. The groundwater zone below the Devonian is characterized by units containing stagnant water having high concentrations of total dissolved solids that can exceed 300g/l. The computational sequence involves the calculation of steady-state density independent flow that is used as the initial condition for the determination of pseudo-equilibrium for a density dependent flow system that has an initial TDS distribution developed from observed data. Long-term simulations that consider future glaciation scenarios include the impact of ice thickness and permafrost. The selection of the performance measure used to evaluate a groundwater system is important. The traditional metric of average water particle travel time is inappropriate for geologic units such as the Ordovician where solute transport is diffusion dominant. The use of life expectancy and groundwater age is a more appropriate metric for such a system. The mean life expectancy for the DGR and base case parameters has been estimated to be in excess of 8 million years.

Full textAbstract:
Ontario Power Generation (OPG) has developed and implemented a systematic managed process for steam generators at all of its facilities. One of the key requirements of this managed process is to have in place long range Steam Generator Life Cycle Management (SG LCM) plans for each of its reactor units. The primary goal of these plans is to maximize the value of the nuclear facility through safe and reliable steam generator operation over the expected life of the units. These SG LCM plans integrate and schedule all steam generator actions such as inspection, operation, maintenance, repairs, modifications, assessments, performance monitoring, research and development, and feedback. This paper provides an overview of how structural and leak-rate testing, being conducted by OPG, is being used to support fitness-for-service assessments for fretting degradation in the U-bend region of the recirculating steam generators at the Darlington Nuclear Generating Station.

Established in the 1930s, the Northern Transportation Route (NTR) served to transport pitchblende ore 2,200 km from the Port Radium Mine in Canada’s Northwest Territories to Fort McMurray in Alberta. From there, the ore was shipped 3,000 km by rail to the Town of Port Hope, Ontario, where it was refined for its radium content and used for medical purposes. Later, transport and refinement focussed on uranium. The corridor of lakes, rivers, portages and roads that made up the NTR included a number of transfer points, where ore was unloaded and transferred to other barges or trucks. Ore was occasionally spilled during these transfer operations and, in some cases, subsequently distributed over larger areas as properties were re-developed or modified. In addition, relatively small volumes of ore were sometimes transported by air to the south. Since 1991, the Low-Level Radioactive Waste Management Office (LLRWMO), working with communities and its consulting contractors, has conducted surveys to identify and characterize spill sites along the NTR where soils exhibit elevated concentrations of uranium, radium and/or arsenic. In addition to significant areas of impact in Fort McMurray, contamination along the NTR was centred in the Sahtu region near Great Bear Lake and along the southern part of the Slave River. Early radiological investigations found contaminated buildings and soil and occasionally discrete pieces of pitchblende ore at many transfer points and storage areas along the NTR. Where possible, survey work was undertaken in conjunction with property redevelopment activity requiring the relocation of impacted soils (e.g., at Tulita, Fort Smith, Hay River, and Fort McMurray). When feasible to consolidate contaminated material locally, it was placed into Long Term Management Facilities developed to manage and monitor the materials over extended timelines. Radiological activity generated by these engineered facilities are generally below thresholds established by Canadian regulators, meaning they are straightforward to maintain, with minor environmental and community impacts. Securing community acceptance for these facilities is critical, and represents the predominant development component of plans for managing ore-impacted soils. In those circumstances where local consolidation is not achievable, materials have been relocated to disposal facilities outside of the region. The LLRWMO is continuing a program of public consultation, technical evaluation and environmental assessment to develop management plans for the remaining ore-impacted sites on the NTR. This paper will highlight current activities and approaches applied for the responsible management of uranium and radium mining legacies.
