A Comparative Ecological Study Of Limestone And Dolomite Glades In The Ozark Mountains Of Northwest Arkansas, Brittney Booth
Graduate Theses and Dissertations
Glades are one of the many habitats that exist in the Arkansas Ozarks and contribute to the overall biodiversity of the state of Arkansas. For this study, five dolomite glades and five limestone glades in the Ozarks of northwest Arkansas were studied from March to October in the years 2017 and 2018 to determine the similarities or differences that might be present. One hundred and fifteen vascular plant taxa were documented in the dolomite glades and one hundred and three vascular plant taxa were documented in the limestone glades. Forty-six vascular plant taxa were unique to the dolomite glades and …
Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead
Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead
Graduate Theses and Dissertations
It has been shown that bird communities are affected by the species composition and physical structure of plant communities. Within avian communities, the bird species that are the most localized in distribution tend to be the most affected by habitat changes. My research analyzed plant and bird communities found with the Painted Bunting (Passerina ciris Linnaeus), a locally common but declining species throughout much of its range. First, I describe vegetation characteristics associated with singing male Painted Buntings in northwest Arkansas. I categorized field sites with singing male Painted Buntings as either managed for wildlife or unmanaged, based on land-use …
Alliaria Petiolata (M.Bieb.) Cavara & Grande [Brassicaceae], An Invasive Herb In The Southern Ozark Plateaus: A Comparison Of Species Composition And Richness, Soil Properties, And Earthworm Composition And Biomass In Invaded Versus Non-Invaded Sites, Jennifer D. Ogle
Graduate Theses and Dissertations
Invasive species are widely recognized as organisms that severely alter ecosystem processes in the habitats to which they are introduced. Alliaria petiolata is one of the most important invasive plants in forests of the northern United States. This study examined the geographic distribution of the plant in the southern Ozarks, as well as the effect that it may be having on natural processes within forests of the region by comparing plant species richness, plant cover, and soil properties in invaded and non-invaded plots. It was found that A. petiolata is not significantly altering species richness, cover, or soil properties in …
Habitat Assessment Of Two Narrowly Endemic Plant Species, Ozark Spiderwort (Tradescantia Ozarkana) E. S. Anderson And Woods. And Newton's Larkspur (Delphinium Newtonianum) D. M. Moore, Autumn Lynn Coffey Olsen
Habitat Assessment Of Two Narrowly Endemic Plant Species, Ozark Spiderwort (Tradescantia Ozarkana) E. S. Anderson And Woods. And Newton's Larkspur (Delphinium Newtonianum) D. M. Moore, Autumn Lynn Coffey Olsen
Graduate Theses and Dissertations
The threat of biodiversity loss is upon us with the onset of climate change and our ever-demanding needs of the Earth's resources for a rapidly growing human population. Species highly vulnerable to loss are those limited in abundance and distribution, or those with reduced genetic diversity. Efforts to actively conserve a sensitive species require effectual data on the probable causes of their vulnerability. Two species of concern, Delphinium newtonianum and Tradescantia ozarkana, are globally rare endemic vascular plant species found only in the Interior Highlands of North America. In an attempt to understand the causes for their endemism, habitat …

Microbial Biomass And Nitrogen Availability Under The Invasive Plant Species Lonicera Japonica And Native Grasses In Wetland Soil, Kimberly R. Payne, Mary C. Savin, Peter J. Tomlinson
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Invasive plants decrease aboveground biodiversity and suitable wildlife habitat. Wetlands are especially valuable ecosystems because they provide habitat, floodwater control, and function as filters for urban runoff. Wetland soils also act as sinks for nutrients. This characteristic reduces levels of excess nutrients often found in adjacent aquatic systems. The importance of soil functions in wetlands necessitates further investigation of the effects of invasive species on belowground nutrient pools. Approximately 75% of a small neighborhood wetland located in Fayetteville, Ark., has been invaded by Lonicera japonica. The effects of L. japonica and its replacement with native grasses on soil microbial biomass …

Characteristics Of Some Fruiting Plant Species In Northwest Arkansas, And The Avian Assemblages That Feed On Them, John W. Prather, Kimberly G. Smith, Michael A. Mlodinow, Cecilia M. Riley
Journal of the Arkansas Academy of Science
Fruits continue to be recognized as an important food source for birds in temperate areas, particularly during the fall migration period. More than 20 species of plants producing fleshy fruits are found in the Arkansas Ozarks. However, only a few of these appear to be important resources for birds during the fall migration period (August - October). Among those are sassafras (Sassafras albidum), gray-backed grape (Vitis cinerea), black cherry (Prunus serotina), hercules club (Araliaspinosa) and pokeweed (Phytolacca americana). Over the past 4 years, we have documented the physical and nutritional characteristics of those fruits and taken observational data on the …
Effects Of Litter On Aquatic Macrophyte Germination And Growth, Mark F. Carter, Forrest E. Lane, James B. Grace
Effects Of Litter On Aquatic Macrophyte Germination And Growth, Mark F. Carter, Forrest E. Lane, James B. Grace
Journal of the Arkansas Academy of Science
In Arkansas, during seasonal drought periods, lake water levels drop leaving exposed mudflats which are primary sites for seedling establishment. Commonly, these exposed mudflats are partially covered with decomposing litter from previous stands of aquatic plants. In this study, aqueous leachates from the litter of four macrophytes, Eleocharis quadrangulata, Justicia americana, Polygonum lapathifolium, and Potamogeton nodosus, were used to test for chemical interference with germination and seedling growth. Only Justicia americana leachate was found to affect the growth of several of the test species. The potential for chemical interference by Justicia litter was evaluated further using extracts of acidified leachate. …

The Distribution Of Cane, Arundinaria Gigante (Poaceae: Bambusoideae), Daniel L. Marsh
The Distribution Of Cane, Arundinaria Gigante (Poaceae: Bambusoideae), Daniel L. Marsh
Journal of the Arkansas Academy of Science
The distribution of cane in the United States was compiled on a county basis from previous records, correspondence, and field work. Ecological correlations were considered. The range appears to be limited primarily by temperature and precipitation. Two geographic populations correlate with major drainage divisions. The broad ecologic amplitude of cane is indicated by its occurrence in many different community types.

Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker
Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker
Journal of the Arkansas Academy of Science
Castanea ozarkensis Ashe, the Ozark chinquapin of the vascular plant family Fagaceae, is distributed widely throughout the Interior Highlands of Arkansas and the adjacent states of Missouri and Oklahoma. Examination of material from throughout the range of C. ozarkensis indicates demonstrable morphological intergradation with C. pumila (L.) Miller sensu lato, the chinquapin of wide distribution in much of the eastern United States. It is proposed that C. ozarkensis be reduced to C. pumila var. ozarkensis (Ashe) Tucker, comb. nov.
Variation In Ligule Spotting In Coreopsis Basalis, Edwin B. Smith
Variation In Ligule Spotting In Coreopsis Basalis, Edwin B. Smith
Journal of the Arkansas Academy of Science
The ligules of Coreopsis basalis bear an attractive reddish-brown spot at the base. The spot has been used as a taxonomic character of the species. But there is variation within populations at any one time, and within individuals at sequential times, for the size of the spot. A few individuals lack the ligule spot entirely. Variation in average ligule spot size in greenhouse-grown populations of C. basalis and an artificial hybrid is described. Average spot size declines as the blooming season progresses. Some individuals with spotted ligules early in the season bore spotless ligules late in the season. No correlation …

Studies Of Arundinaria: Experimental Induction Of Flowering And Additional Observation In The Field, Daniel L. Marsh
Studies Of Arundinaria: Experimental Induction Of Flowering And Additional Observation In The Field, Daniel L. Marsh
Journal of the Arkansas Academy of Science
Arundinaria has been observed for three successive seasons at a site near Amity, Arkansas. In advance of the 1971 flowering period rhizomes were taken from the field, pruned, and placed either in an environmental chamber or in the greenhouse in water or in sandy soil. Flowering occurred under each condition, but was most rapid and profuse in transplants growing in sandy soil in the greenhouse. Observations point to the possibility of induction of flowering or to the possible existence of an annually flowering race. Possible economic uses are considered.
