  • General Forest Habitat Association
    07/15/2003 Viability Assessment Report For General Forest Habitat Association Prepared by Timothy O. Reed Daniel Boone National Forest I. Description of Habitat Association The General Forest Habitat Association encompasses a wide range of forest conditions and can potentially include any soil, forest type, or land type association (LTA) which occurs on the Daniel Boone National Forest (DBNF) (see USDA Forest Service, 1997a). Forested terrain ranges from hilly to rugged in the Cumberland Plateau, which encompasses most of the DBNF and is intersected by cliffs in the higher elevations and by drainages of the Cumberland, Kentucky and Licking Rivers at lower elevations. Steepest terrain occurs in the Cumberland Mountains, which border the southeastern section of the DBNF. This habitat association includes both hardwood and pine trees, as well as stands that are a mixture of both, along with their associated plant and animal species. Hardwood predominates on all districts, with pine more abundant on the southern half of the DBNF (the London, Somerset, and Stearns Districts). Because this is a broad and encompassing habitat association, general forest might best be described as the typical forest scene that comes to mind when one thinks about being out in woods within the DBNF. Many events may have shaped this forest scene including disturbance from storm events, natural tree mortality, wildfires, insect and disease mortality and natural succession. Management activities have also impacted this scene through timber harvest, prescribed burning, timber stand improvement treatments, trails and recreation developments, mineral extraction, and wildlife habitat improvement activities. This is an association in which species are found that utilize a wide range of general forested conditions.

  • Fire in the Southeastern Grasslands, By
    Fire in the Southeastern Grasslands RICHARD J. VOGL Department of Biology California State University Los Angeles, CA 90032 INTRODUCTION ~ERE has been more research on the effects of fire in the southeastern United States than in any region of North America. Most studies have been concerned with the effects of fire on the trees, including the role of fire in controlling hardwood suc­ cession, fire damage to trees, the effects of fire on soils and litter, the influence of fire on conifer growth and reproduction, and the relationships of fire to tree diseases (Garren 1943; Ahlgren and Ahlgren 1960; Cushwa 1968). A lesser, but stilI substantial number of studies have been focused on the effects of fire on forage yields and livestock production (Wahlenberg et al. 1939), and the use of fire in wildlife management in the Southeast. But academic or phy­ tosociological studies of the vegetational composition and of the effects of fire on the understory vegetation are generally lacking. Except for some range and wildlife research and several general studies (Wells and Shunk 1931; Leukel and St<Jkes 1939; Biswell and Lemon 1943; Burton 1944; Lemon 1949, 1967; Campbell 1955; Biswell1958; Hodgkins 1958; Arata 1959; Cushwa et al. 1966, 1970; Wolters 1972) , most investigators have ignored the herbaceous cover or grassland vegetation under southeastern trees. Even early botanists often became more interested in the unusual botanical features such as the southern extent of Appalachian tree species (Harper 1943, 1952), the description of the silaceous dunes of the 175 RICHARD J. VOGL Gulf Coast (Kurz 1942), the habits of eastern red cedar (Harper 1912), the vegetation of the Okefenokee Swamp (Wright and Wright 1932), or why the Black Belt Prairie of Alabama was treeless (Ranking and Davis 1971), thereby neglecting the widespread and common grassland vegetation and its relationship to fire.

  • Chapter 4 Native Plants for Landscape Use in Kentucky
    Chapter 4 Native Plants for Landscape Use In Kentucky A publication of the Louisville Water Company Wellhead Protection Plan, Phase III Source Reduction Grant # X9-96479407-0 Chapter 4 Native Plants for Landscape Use in Kentucky Native Wildflowers and Ferns The U. S. Department of Transportation, (US DOT), has developed a listing of native plants, (ferns, annuals, perennials, shrubs, and trees), that may be used in landscaping in the State of Kentucky. Other agencies have also developed listings of native plants, which have been integrated into the list within this guidebook. While this list is, by no means, a complete report of the native species that may be found in Kentucky, it offers a starting point for additional research, should the homeowner wish to find additional KY native plants for use in a landscape design, or to check if a plant is native to the State. A reference book titled Wildflowers and Ferns of Kentucky, which was recommended by personnel at the Salato Wildlife Center as an excellent reference for native plants, was also used to develop the list. (A full bibliography is listed at the end of this chapter.) While many horticultural and botanical experts may dispute the inclusion of specific plants on the listing, or wish to add more plants, the list represents the latest information available for research, by the amateur, at the time. The information listed within the list was taken at face value, and no judgment calls were made about the suitability of plants for the list. The author makes no claims as to the completeness, accuracy, or timeliness of this list.

  • Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- ACORACEAE
    Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- ACORACEAE ACORACEAE Martinov 1820 (Calamus Family) The family consists only of Acorus. References: Thompson in FNA (2000); Bogner & Mayo in Kubitzki (1998b). Acorus Linnaeus 1753 (Calamus, Sweetflag) A genus of 2-4 species, widespread in north temperate and subtropical regions. Although traditionally treated as part of the Araceae, recent evidence strongly suggests that Acorus should be segregated in a separate family. A wide variety of morphological, anatomical, and embryological evidence supports the segregation of the Acoraceae (Grayum 1987), a segregation additionally supported by molecular studies (Duvall et al. 1993, Chase et al. 1993). The spathe in Acorus is not morphologically equivalent to the spathe of the Araceae.

    González‑Gutiérrez and Rodríguez‑Garay SpringerPlus (2016) 5:1804 DOI 10.1186/s40064-016-3528-z RESEARCH Open Access Embryogenesis in Polianthes tuberosa L var. Simple: from megasporogenesis to early embryo development Alejandra G. González‑Gutiérrez and Benjamín Rodríguez‑Garay* Abstract The genus Polianthes belongs to the subfamily Agavoideae of the Asparagaceae family formerly known as Agavaceae. The genus is endemic to México and comprises about 15 species, among them is Polianthes tuberosa L. The aim of this work was to study and characterize the embryo sac and early embryo development of this species in order to gener‑ ate basic knowledge for its use in taxonomy, in vitro fertilization and production of haploid plants and to complement studies already performed in other genera and species belonging to the Agavoideae sub-family. It was found that the normal development of the P. tuberosa var. Simple embryo sac follows a monosporic pattern of the Polygonum type and starts its development from the chalazal megaspore. At maturity, the embryo sac is of a pyriform shape with a chalazal haustorial tube where the antipodals are located, just below the hypostase, which connects the embryo sac with the nucellar tissue of the ovule. The central cell nucleus shows a high polarity, being located at the chalazal extreme of the embryo sac. The position of cells inside the P. tuberosa embryo sac may be useful for in depth studies about the double fertilization. Furthermore, it was possible to make a chronological description of the events that happen from fertilization and early embryo development to the initial development of the endosperm which was classified as of the helobial type.

Program of Envir onmental Studies POLLEN-MEDIATED GENE FLOW AND GENETIC VARIATION WITHIN MANFREDA VIRGINICA POPULATIONS OCCURRING IN ADAMS COUNTY, OHIO. (64 pp.) Director of Thesis: Harvey E. Ballard, Jr. Abstract The purpose of this thesis was to investigate pollen-mediated gene flow and genetic variation within populations of Manfreda virginica that occur in prairie openings in Adams County, Ohio. M. virginica was chosen because of its historic co-dominance in the xeric prairies and its role as a dominant plant in globally rare limestone seep habitats. A pollen surrogate was used to estimate pollen dispersal and inferred pollen movement is frequent within populations, but not among populations. A single species of Halictid bee appears to be the primary and perhaps sole pollinator. Genetic analysis was performed using Inter-Simple Sequence Repeat (ISSR) markers. No significant relationship was found between geographic distance and genetic distance and substantial genetic variation is found between all populations regardless of size or geographic position.

One of two major groups of the angiosperms distinguished by the presence of only one leaf (cotyledon) in the embryo. Other typical characteristics are parallel leaf venation, floral organs usually organized in whorls of three, scattered vascular bundles, a rudimentary primary root, which is soon replaced by lateral adventitious roots (ie roots formed by the stem), & the lack of secondary thickening, which is why most Monocotyledons are herbaceous plants (if secondary thickening is present, as in Agave, Aloe, Dracaena, Xanthorrhoea & others, then it is different from Dicots). Monocotyledons include grasses, sedges, rushes, lilies, orchids, bananas, aroids, palms, & their relatives. (sk08). Angiosperms have traditionally been split into monocotyledons & dicotyledons, or plants with one or two seed leaves respectively.
