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 …

Effects of Hydrologic Gradients on Woody Debris Breakdown and Macroinvertebrate Colonization in a Cumberland Plateau Watershed, Eastern Kentucky, U.S.A.
This research assessed the influence of hydrologic gradients on woody debris dynamics in a Cumberland Plateau watershed, eastern Kentucky, U.S.A. Although the breakdown of wood can be attributed to several different processes, including leaching, biological decay, fragmentation, and transport, the …

Assessing Organic Matter Breakdown and Associated Macroinvertebrate Community Structure in Headwater Streams: Effects of Hydrologic Gradients and Upland Timber Harvesting
I examined the effects of hydrologic gradients and upland timber harvesting with different streamside management zone widths on yellow-poplar (<i>Liriodendron tulipifera</i>) processing and the associated macroinvertebrate community structure in the Cumberland Plateau ecophysic region, U.S.A. Prior …

Consequences of drought, flooding, and insect herbivory on the distributions of closely related willow and poplar (Salicaceae) species across hydrologic gradients in Minnesota wetlands
… on species performances across environmental gradients. Contributions of different community assembly processes to beta diversity can be tested with multiple approaches. First, experimental approaches allow direct tests of effects of abiotic and biotic factors on species performances across …

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 …

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 …
