ALTERATIONS OF RIVER FLOW REGIMES IN THE NORTHERN ROCKY MOUNTAINS, USA
… data from stream gauges located in natural and anthropogenically-modified river basins of the Northern Rocky Mountains over 59 years. I applied linear and non-linear models to the data to determine what, if any, alterations have occurred in the annual flow regimes. By comparing the different …

AN INVESTIGATION OF HYDROGEOLOGIC, STRATIGRAPHIC, AND STRUCTURAL CONTROLS ON ACER GRANDIDENTATUM COMMUNITIES IN A KARST LANDSCAPE, OWL MOUNTAIN PROVINCE, FORT HOOD MILITARY INSTALLATION, TEXAS
… Neogene that have been complicated by extensive anthropogenic modifications as a result of urbanization, agriculture, and expanding populations in the region. Landscape evolution and the resulting vegetation patterns, examined through the prism of hydrologic and geologic principles, are …

Exploring the Soil-Plant-Atmosphere Continuum: Advancements, Integrated Modeling and Ecohydrological Insights
… has faced unprecedented challenges due to anthropogenic modifications and climate change. Understanding the complex dynamics of this system in response to such changes is crucial for addressing contemporary environmental concerns. Albert Einstein's famous quote, "The measure of intelligence …

Response of riparian plant communities to hydrological alteration: Are seed banks a means of restoration?
The effects of anthropogenic modifications of stream systems on in situ plant community composition and seed bank composition were examined at five riparian sites in the Yazoo River watershed in northern Mississippi. This analysis was performed to determine if the soil seed bank can provide a means …

From landscape to freshwater invertebrates: understanding the effects of peatland restoration on Atlantic Salmon (Salmo salar) habitat in the Flow Country
… they have been severely impacted by various anthropogenic activities, including burning, drainage, over-grazing, and afforestation with non-native conifer plantations. These disturbances have led to well-documented negative effects on ecosystem services, particularly in terms of carbon …

Mechanisms governing avulsions in transient landscapes : analysis of the May 2006 Suncook River avulsion in Epsom, New Hampshire
… from finding a new path. We believe that these anthropogenic modifications directly contributed to the occurrence of the May 2006 avulsion in the Suncook River. These conditions are common throughout New England, and could increase the risk of avulsions in the region.

Water Level Quantiles Of Devils Lake Under Down-Scaled Gcm Predictions Using A Coupled Hydro-Climatic Model
… GCM runs under varying scenarios due to anthropogenic modifications and the resulting composition of the atmosphere. 100 traces of future water levels of the Devils Lake have been generated using the predicted temperature and precipitation by the GCMs. The synthetic traces show a downward …

Coupled dynamics of above- and below-ground interactions in the critical zone
… a balance between the natural dynamics and anthropogenic modifications. In this study I have developed a predictive understanding of the above- and below-ground interactions that occur in the CZ in the light of different dynamics involving water, carbon, nitrogen, energy, and thermodynamic …

Observation-Based Algorithm Development For Subsurface Hydrology In Northern Temperate Wetlands
… Another case study evaluated the role of anthropogenic modifications to drainage conditions and wetland extent on streamflow in the upper Wabash River basin. An initial test case demonstrated that a depressional wetland perched on the Tipton Till Plain tends to recharge soil moisture in …

Testing alternative stable state theory at Afromontane and Milkwood forest-fynbos ecotones
… differences between the contrasting ecosystems. Anthropogenic modifications to disturbance regimes alter the stability of forests and fynbos and may shift forest and fynbos into a degraded species-poor state. Conservation practitioners are concerned over perceived loss of forest habitat, and tree …

Management and Mother Nature: piping plover demography and condition in response to flooding on the Missouri River
… riparian ecosystems are in decline due to anthropogenic modifications including damming, channelization and the conversion of the floodplain for human use. These changes can profoundly affect riparian species as many have adapted to the historical dynamism of these ecosystems. On the …

Striking a balance between water for food, energy, and the environment: a quantitative framework to guide sustainable water management for a changing future
… to differences in their geologic pasts and human modifications such as artificial drainage and reservoir operation. These differences manifest temporally, from annual to daily time scales, and spatially, both within and between the watersheds, suggesting a complex, nonlinear response to other, …
