Abstract This research uses image classification and machine learning methods on radar reflectivity mosaics to segment, classify, and track quasi-linear convective systems (QLCSs) in the United States for a 22-yr period. An algorithm is trained and validated using radar-derived spatial and intensity information from thousands of manually labeled QLCS and non-QLCS event slices. The algorithm is then used to automate the identification and tracking of over 3000 QLCSs with high accuracy, affording the first, systematic, long-term climatology of QLCSs. Convective regions determined by the procedure to be QLCSs are used as foci for spatiotemporal filtering of observed severe thunderstorm reports; this permits an estimation of the number of severe storm hazards due to this morphology. Results reveal that nearly 32% of MCSs are classified as QLCSs. On average, 139 QLCSs occur annually, with most of these events clustered from April through August in the eastern Great Plains and central/lower Mississippi and Ohio River Valleys. QLCSs are responsible for a spatiotemporally variable proportion of severe hazard reports, with a maximum in QLCS-report attribution (30%–42%) in the western Ohio and central Mississippi River Valleys. Over 21% of tornadoes, 28% of severe winds, and 10% of severe hail reports are due to QLCSs across the central and eastern United States. The proportion of QLCS-affiliated tornado and severe wind reports maximize during the overnight and cool season, with more than 50% of tornadoes and wind reports in some locations due to QLCSs. This research illustrates the utility of automated storm-mode classification systems in generating extensive, systematic climatologies of phenomena, reducing the need for time-consuming and spatiotemporal-limiting methods where investigators manually assign morphological classifications.

Blastomyces dermatitidis is a fungus endemic in the central and eastern United States. It is coendemic with Histoplasma capsulatum in much of the central and southeastern United States, including the Mississippi and Ohio river valleys. Distribution of B dermatitidis extends farther north and west than H capsulatum and includes northern Wisconsin, Minnesota, Ontario, and Manitoba. Fungal growth occurs in nitrogen-rich soils close to streams, rivers, and lakes. Many outbreaks of blastomycosis occur within 100 meters of recreational water. Infection can be asymptomatic or can cause flulike symptoms, pneumonia, or skin, bone or CNS manifestations. Diagnosis and treatment are also reviewed.

The effigy mounds of the Upper Midwest and the Ohio Valley long have been regarded as distinct and independent cultural developments. A review of effigy mound iconography in both regions reveals similarities suggesting that they are elements of a shared cultural tradition. Comparisons with rock art imagery from the Upper Midwest and Missouri, the inferred centers of this artistic and ceremonial florescence, reveal co-occurrences of specific motifs and provide additional evidence of cultural connections among the Late Woodland to early Late Precontact societies inhabiting the lower Missouri, Mississippi, and Ohio river valleys. Oral traditions of Native American groups with documented connections to these regions allow this rich corpus of imagery to be understood as key episodes in their genesis stories.

AbstractHistoplasmosis is a global disease endemic to regions of all six inhabited continents. The areas of highest endemicity lie within the Mississippi and Ohio River Valleys of North America and parts of Central and South America. As a result of climate change and anthropogenic land utilization, the conditions suitable for Histoplasma capsulatum are changing, leading to a corresponding change in epidemiology. The clinical manifestations of histoplasmosis are protean, variably resembling other common conditions such as community-acquired pneumonia, tuberculosis, sarcoidosis, Crohn's disease, or malignancy. Making a successful diagnosis is contingent on a thorough understanding of epidemiology, common clinical presentations, and best testing practices for histoplasmosis. While most subclinical or self-limited diseases do not require treatment in immunocompetent patients, all immunocompromised patients and those with progressive disseminated disease or chronic pulmonary disease should be treated. Liposomal amphotericin B is the preferred agent for severe or disseminated disease, while itraconazole is adequate for milder cases and “step-down” therapy following response to amphotericin B. In this review, we discuss the current evidence-based approaches to the epidemiology, diagnosis, and management of histoplasmosis.

The North-Eastern Altai is an ultra-humid area with climax vegetation represented by tall-herb fir (Abies sibirica) dark-coniferous forest. Its meadows belong to the class Molinio-Arrhenatheretea. The typical asso­ciation Aegopodio podagrariae—Dactyletum glomeratae originates in the watershed clearings after climax forests whereas ass. Hyperici perforati—Agrostietum giganteaereplaces the previous one under mowing and grazing. The Molinietalia wet meadows are widespread in the river valleys. The meadows of ass. Cirsio heterophylli—Calama­grostietum langsdorffii occur on wet soils in small depressions and along floodplain mire margins, and ass. Ca­rici ovalis—Deschampsietum cespitosae comprises typical floodplain hay-meadows on moist, nutrient-rich soils.
