The Multiphonic Fens
The Multiphonic Fens is a practice-based, site-specific sonic research project that generates original compositional narratives through the practice and process of field recording in the East Anglian Fens. The field recordings are transformed into unique compositions that reflect the subjective …

Improvement and environmental conflict in the northern fens, 1560-1665
… drainage project in England, in the northern fens of Hatfield Level, in the context of the local politics of custom, national legal and political developments, and international movements of capital, expertise, and refugees; all of which intersected to reshape perceptions and management of …

The Role of Temperature in the Seed Germination Ecology of Mountain Springs and Fens
Mountain calcareous spring fens are floristically diverse wetlands fed by carbonate-rich groundwater. This thesis studies their seed ecology, focusing on the interaction between environmental temperature and germination. To this end we conduct laboratory germination experiments with calcareous …

Distinguishing the hydrologic regimes and vegetation of fens and wet meadows in the Rocky Mountains
Fens and wet meadows in the Rocky Mountains are groundwater fed wetlands that are infrequent on the landscape but critical for the support of biodiversity and ecosystem functions. Organic vs. mineral soil layer classifications, hydrologic regime and vegetation indicators have been used to …

Long-Term Hydrologic Sustainability of Calcareous Fens Along Glacial Lake Agassiz Beach Ridges, Northwestern Mn
Calcareous fens are peat-accumulating wetlands fed by calcium-rich groundwater that support several threatened species of plants that evolved to thrive in these geochemical conditions. Fifty-three of Minnesota’s nearly 300 identified calcareous fens are located in the Glacial Lake Agassiz beach …

ASSESSING THE ROLE OF GEOLOGIC SETTING ON THE HYDROLOGY AND GROUND WATER GEOCHEMISTRY OF FENS IN THE GLACIATED MIDWESTERN UNITED STATES
… THE HYDROLOGY AND GROUND WATER GEOCHEMISTRY OF FENS IN THE GLACIATED MIDWESTERN UNITED STATES A water quality investigation of several fens located in the temperate glaciated Midwestern United States, near the southern limit of fen occurrence, was conducted to assess the role of geologic setting …

EFFECTS OF GROUND-WATER FLOW ON SOIL CHEMISTRY, NUTRIENT AVAILABILITY AND PLANT SPECIES DISTRIBUTIONS IN FOUR NEW YORK STATE FENS
Occurrence of distinctive plant communities, rich fens, in specific hydrogeologic settings with high fluxes of calcium-rich ground water has been observed but not fully explained. In fens, ground-water discharge patterns induce spatial gradients in water chemistry that may determine vegetation …

Variations in Water Storage Capacity of a Mountain Peatland with Complex Stratigraphy
… occur in valley bottoms and are classified as fens. Understanding how fens influence water storage and water release is essential for better predicting water availability as the climate changes. Peatlands located in mountain regions tend to have a complex soil profile due to the …

The Response of High Elevation Wetlands to Past Climate Change, and Implications for the Future
… of the ongoing investigation of mid-latitude fens in Colorado by University of Denver paleoenvironment researchers, research directed at examining the response of mid-latitude subalpine fens to past climatic events potentially analogous to modern anthropogenic climate change was undertaken. As …

A phenomenological study of the lived experiences of foreign educated nurses working in the United States of America.
… lived experiences of foreign educated nurses (FENs) working in the United States of America (US). Since World War II, the US has recruited FENs to fill recurring workplace vacancies of registered nurses (RNs). Despite this long history, few studies have examined the lived experiences of FENs …

Ecological Drivers of Plant Community Composition in a Patterned Fen at Seney National Wildlife Refuge, Michigan
… Hemisphere. In the Great Lakes region, patterned fens have been extensively studied in northern Minnesota, but largely ignored in Michigan. The purpose of this study was to describe vegetation, landforms, and water chemistry in a patterned fen at Seney National Wildlife Refuge. Percent cover of …
