Vascular flora of Bark Camp Barrens WMA, Coffee County, Tennessee
A vascular plant inventory of Bark Camp Barrens Wildlife Management Area, Coffee County, Tennessee was performed over the 2023 and 2024 growing seasons. The site is a 1,395-ha area located 10km east of Manchester, Tennessee in the Barrens region of the Eastern Highland Rim. A total of 698 species …

Fire History of an Acidic Barrens Complex: A Methods Assessment of Fire Return Intervals
Fire-scarred trees provide an important source of data and direct evidence for understanding past fires and vegetation dynamics. Although dendrochronological fire scar records provide fine-scale temporal and spatial resolution, limitations exist in the development, analysis, and interpretation of …

Factors affecting plant community composition and dynamics in the Ossipee Pine Barrens, New Hampshire
… 0.25 ha sites were sampled in the Ossipee Pine Barrens to identify and describe tree community types and investigate factors controlling forest composition and dynamics. Every site had three site-time assemblages (STA's) representing past, present, and future trees. Past (1952) vegetation was …

Overcoming evolutionary history: conditioning the endangered Barrens topminnow to avoid predation by the invasive Western mosquitofish
… are one cause of evolutionary traps, and the Barrens Topminnow (BTM), Fundulus julisia serves as an example of an imperiled species trapped by the introduction of an invasive predator: the Western Mosquitofish (WMF), Gambusia affinis. This study used conditioning to help the BTM escape its …

The Effects of USDA Farm-Bill Restoration Programs on Prairie Voles (microtus ochrogaster) in the Barrens Region of Kentucky
Much of the area that is now west-central Kentucky historically existed as grass dominated ecosystems. Unfortunately, most of those grasslands are gone due mostly to disturbance suppression and conversion to agricultural lands. Federal, state, and nongovernmental agencies have, particularly within …

Biotic and Abiotic Factors of Picea rubens (Red Spruce) Seedling Regeneration in Disturbed Heathland Barrens of the Central Appalachians
… communities have both persisted in natural barrens and expanded into formerly forested areas. To understand abiotic and biotic conditions guiding the advance of the red spruce stand, I conducted a broad-scale assessment of thirty-one demographics plots spread across two sites (north Cabin …

Population Dynamics in Response to Fire in <i>Quercus laevis - Pinus palustris</i> Barrens and Related Communities in Southeast Virginia
<p>Permanent plots in the Zuni Pine Barrens (Isle of Wight Co., Virginia) were sampled in order to: quantify plant population dynamics in response to fire, compare these dynamics among different moisture regimes, compare the effect of mechanical understory removal to that of fire on tree seedling …

Vegetation Ecology and Fire Effects on Community Structure, Composition, and Diversity in a Barrens Remnant and a Flatwoods in Southern Illinois
Fire effects on composition and diversity at both sites were greatest in the ground-layer vegetation as there were significant increases in species diversity and cover and dramatic changes among dominant species. Most increase in species diversity appears to be from soil seed banks. At GCB the …

Social learning and its effect on conservation efforts in the Barrens Topminnow: an evaluation of conditioning and social learning as a viable longterm solution to evolutionary traps
… multiple freshwater fish species, including the Barrens Topminnow (BTM), Fundulus julisia. In my study, I investigated if BTMs are capable of socially learning conditioned predator recognition, and I hypothesized that BTMs are capable of social learning and that such learning might improve …

Spatial Pattern Analysis of Tree Species Distribution in a Central Appalachian Upland Heath Barren
… tree species distributions in the upland heath barrens on Cabin Mountain in Canaan Valley, West Virginia through fieldwork, statistical modeling, and the use of geographical information systems (GIS). The research objectives were to: 1) quantify the global and local spatial patterns of trees to …

The acclimation ability of the shale barren endemic Eriogonum alleni to light and heat
Shale barrens are unique habitats located throughout the southern Appalachians. They are characterized by a south or south west aspect, a steep slope, and an exposed rocky surface (Platt, 1951). They have a high total irradiance and can experience temperatures higher than the surrounding deciduous …

The reproductive ecology of Minuartia patula Michx. Mattf. (Caryophyllaceae)
… (Caryophyllaceae), is a winter annual found in barrens, glades, rocky outcrops, and dolomite prairies of the eastern and central United States. This species is rare in Illinois, Indiana and Ohio; and vulnerable in Kentucky, Missouri, and Virginia. Though research on environmental pollution, seed …

Effects of Management and Population Size on Genetic Diversity of Eggert's Sunflower (HELIANTHUS EGGERTII; ASTERACEAE)
… that typically grows between open woods and barrens. This species has both sexual and asexual modes of reproduction, which can influence the amount of genetic diversity present within and among populations. Maintaining genetic diversity is one of the primary objectives in managing threatened …

Metapopulations and metacommunities in dry forest openings in southern Illinois
… openings. Forest openings (commonly called barrens, hill prairies, or glades) are habitats found on ridgetops which are characterized by having thin or nutrient-poor soil, high sunlight exposure, and relatively low soil moisture when compared to nearby forest habitats. Forest openings …

The rise and fall of the spiny lobster (Jasus edwardsii) in the Hauraki Gulf, northeastern New Zealand
… importance of protecting J. edwardsii if urchin barrens are to be controlled or prevented in the Hauraki Gulf. Overall, these findings demonstrate the significant impacts of fishing on population density and behaviour of J. edwardsii and highlight the precarious state of the J. edwardsii …

Influence of Forest Management on Bumblebee-Plant Networks and Community Compositions in Eastern Kentucky Forest Openings
… Naturally occurring forest openings, barrens, and grasslands have historically provided important habitat for native bees across the otherwise forested landscape in the eastern United States. Fire suppression and the loss of these important habitats are well-documented, but it is …
