Early Successional Processes of Experimentally-Reclaimed Mine Sites in Eastern Ohio and the Restoration of American Chestnut
… chestnut and the Appalachian coal fields are nearly concurrent, possibly making these experimentally reclaimed sites ideal for restoration plantings of disease-resistant chestnut hybrids. The work here has been conducted on an experimentally-reclaimed mine site in Belmont County Ohio, and …

The red imported fire ant, Solenopsis invicta, in early-successional coastal plain forests: tests of distribution and interaction strength
… is an abundant and aggressive component of early-successional communities in the southeastern United States. After disturbance, it rapidly invades new habitats, and once there, it has strong competitive and predatory effects on the existing arthropod community. In upland coastal plain pine …

WHAT PREDICTS TERRESTRIAL INVERTEBRATE SUBSIDY USE BY BROOK TROUT (SALVELINUS FONTINALIS) IN HEADWATER STREAMS?
… in terrestrial invertebrate biomass in early and late successional habitats. To test this prediction, I measured terrestrial invertebrate biomass, input to streams, and use by resident brook trout in 12 first and second-order watersheds in northern New Hampshire, USA, representing a …

Effects of forest disturbance on shredder production in headwater streams
… due mostly to better survivorship and growth of early instar larvae in disturbed streams. T. maria and T. abdominalis were studied under laboratory conditions to determine whether feeding on various types of leaf material would affect growth. Shredder growth rates were affected more by length of …

Stand Dynamics in a Southern Appalachian Montane Pine Barren, Warm Springs Mountain, Virginia
… of western Virginia is likely threatened by successional changes initiated by a history of fire suppression. Dominated by early successional fire adapted species, such as dwarfed Pinus rigida (Mill.) and Quercus ilicifolia (Wangenh.), this shrubland is home to numerous rare plants and …

Comparison of Bare Root vs. Potted Plants, Species Selection, and Caging Types for Restoration of a Prairie Wetland, and Quantitative Analysis and Descriptive Survey of Plant Communities and Associations at Lewisville Lake Environmental Learning Area (LLELA), Lewisville, TX
… property demonstrates the characteristics of an early successional community, dominated by weedy species. Prairie communities are dominated by Johnson grass and ragweed, with climax tall grass prairie communities only in areas that have been planted with native grass seed. Forest communities are …

Effects of experimental disturbance on multi-taxa assemblages and traits: conservation implication in a forest-open landscape mosaic
… connectivity through plantation forest for early-successional biodiversity. Both species composition and life history traits were investigated enabling a comprehensive interpretation of response across multiple species. Sampling programs identified over 87000 invertebrates, comprising 38188 …

Impacts of non-renewable resource extraction on shrubland songbird nest success and abundance
… habitat. Land management practices which produce early-successional habitat, namely field abandonment and clearcut timber harvests, have become increasingly uncommon in the eastern United States, and natural maintenance processes such as fires and floods are often suppressed. The Appalachian …

Movements, Survival, and Habitat Relationships of Snowshoe Hares Following Release in Northeast Ohio
… of northeastern Ohio, but were extirpated by the early 1900s. Attempts were made to reintroduce snowshoe hares in northeastern Ohio duringthe 1950s. However, these releases failed to establish a viable population. Causes of failure are unknown because the releases were poorly documented and …
