A feasibility assessment of native ferns for phytoremed[i]ation of arsenic 2012 3896 Arsenic contamination is a world-wide concern. In the past, soil contaminated with arsenic was removed using heavy equipment resulting in the destruction of the environment. However, in recent years a new method, phytoremediation, removes arsenic and...
Habitat analysis of a disjunct population of the Carolina northern flying squirrel (Glaucomys sabrinus coloratus) 2012 3843 The northern flying squirrel Glaucomys sabrinus occurs in a variety of forest types over most of North America, with disjunct populations in the southern Appalachians, Black Hills, southern Rocky Mountains, and Sierra Nevada (Wells- Gosling and He...
Variation in germination and growth among populations of an invasive plant, Alliaria petiolata (M. Bieb) Cavara and Grande 2014 1298 There are many different reasons why a non-native plant species might become invasive in a novel habitat. Some studies have focused on trying to determine the genetic structure of an invasive species. Other studies have investigated whether they a...
Holocene environmental history of Panthertown Valley in the Blue Ridge Mountains of North Carolina 2014 3024 Panthertown is a high-elevation valley in the Nantahala National Forest, and is one of few sites in western North Carolina with natural wetlands. Radiocarbon dating of multiple cores at a Panthertown valley wetland shows continuous deposition through...
The germination of Helonias bullata L. (Swamp pink) in response to flooded, saturated, and dry conditions 2013 2415 Poor sexual recruitment is a major conservation concern for the federally threatened, obligate wetland species Helonias bullata L. (swamp pink). Helonias predominately occurs in forested wetlands amongst hummock-hollow topography where water levels f...
The role of the soil seed bank in Southern Appalachian wildfire response 2018 623 Wildfire disturbance is likely to increase in Southern Appalachian forests due to climate change and anthropogenic land-use changes. The soil seedbank can be a source of plant community response after this disturbance. Fire can affect seeds and seed ...
Photosynthesis, water use, and biomass allocation of princess tree (paulownia tomentosa) and tulip poplar (liriodendron tulipifera) first year seedlings across light and prescribed fire conditions 2021 329 Forest communities experience disturbances, such as fire and canopy removal, which create light gradients and microclimates that affect establishment, carbon gain, and height of native and invasive pioneer tree species that flourish in open or full s...
A biosocial study exploring self-reported vs predicted ancestry using the Verogen ForenSeqâ„¢ signature prep kit 2021 187 Since the 1900s forensic scientists have generally relied upon short tandem repeats (STRs) as a DNA typing method used for positive identification or exclusion of suspects in crimes. STR typing, while well established, requires comparison to a refere...
Floral visitation in two high-elevation rock outcrop communities 2022 211 In the southern Appalachian Mountains, sparsely distributed rock outcrop communities harbor a significant number of rare and endemic plants. Unique communities of plants are found on rock outcrops of differing bedrock, distinguished in this study as ...
Impacts of an invasive grass Microstegium vimineum (Trin.) A. Camus on growth and survival of the native herb, Impatiens capensis Meerb. 2015 926 Microstegium vimineum (Trin.) A. Camus is an invasive annual grass in the eastern United States. It can form dense monocultures along roads and forest understories, displacing native species due to its superior ability to compete for light and soil r...
Effects of variations in tree canopy openness, prey abundance, and abiotic factors on bat activity in the Nantahala National Forest 2018 336 Early successional habitat is known to be a source of foraging habitat for bats, and studies have shown that bat activity is higher in disturbed and open vegetation structures. This study analyzed the importance of early successional habitat, created...
Restoration of Red Spruce Forest: Understory Plant and Soil Responses to Canopy Gaps at Roan Mountain, NC 2022 49 Red spruce-Fraser fir dominated forests are considered threatened in the southern Appalachian Mountains and are known to support a variety of rare and endemic species. Their range has diminished greatly due to human disturbance over the past century,...
Wildfire effects on small mammals in Western North Carolina 2019 305 Fire can impact an ecosystem by changing environmental factors and small mammal abundances. Historically, wildfires have been uncommon in high elevation northern hardwood forests of the Southern Appalachian Mountains. In addition, little is known abo...
