Variability and Drivers of Forest Communities at the Great Dismal Swamp
… and ditching) have resulted in altered hydrologic regime, homogenized forest communities, and increased peat subsidence. In response, hydrologic restoration and forest management aim to enhance community composition and function. To help inform these efforts, we investigated variability …

Investigation of the Flow and Fate of Nitrate in Epikarst at the Savoy Experimental Watershed, Northwest Arkansas
… of nitrate in the epikarst was traced along a hydrologic gradient using a multi-faceted geochemical approach based primarily on concentration and stable isotope composition of the reactants and products of denitrification. In addition, dye-tracing tests were conducted to assess the flow, solute …

Vegetation patterns along the Middle Fork of the Flathead River, Glacier National Park, Montana
… tolerant occurring in higher discharge classes. Hydrologic conditions necessary to support distinct vegetation cover types and key indicator species along the Middle Fork of the Flathead River were identified and quantified. The natural flow regime of the Middle Fork was described in terms of the …

Spatially variable hydrologic regimes in relation to bog turtle (Glyptemys muhlenbergii) population density
… being typified by precipitation as the major hydrologic input. Groundwater inputs are not only important in taxonomically classifying wetland type, but also contribute in important ways to bog turtle natural history. Bog turtles ectothermically regulate body temperature by utilizing thermally …

Tree Composition Along Edaphic and Hydrologic Gradients in Nonriverine Wet Hardwood Forests
… in plant species composition along a wetness gradient. Although quantitative vegetation analysis for this community has been published, broad drainage classes were used to represent a moisture gradient. We investigated trends along a finer-scaled wetness gradient utilizing a novel wetness …

Herbaceous and woody plant establishment across hydrologic gradients in bottomland reforestation sites
… outcomes are likely constrained by the site’s hydrologic regime, along with other abiotic factors including light availability and the distance from potential colonization sources. However, trees are often planted in restorations without regard to the site’s hydrologic context and do not …
