Intraspecific Sequence Variation of cpDNA Shows Two Distinct Groups Within Magnolia virginiana L. of Eastern North America and Cuba

Author : Hiroshi Azuma

Additional Authors : Richard B. Figlar, Peter Del Tredici, Koen Camelbeke, Alejandro Palmarola-Bejerano, Mikhail S. Romanov

ABSTRACT Magnolia virginiana, the type species of genus Magnolia, is a native American species belonging to section Magnolia. To better understand intraspecific taxonomy of Magnolia virginiana, we conducted molecular phylogenetic analysis based on sequences of cpDNA. Fresh leaves were collected from 28 populations (a total of 133 individuals) covering the entire distribution of the species, …

Phlox ovata L. (Polemoniaceae): Clarification of the Nomenclature of the Allegheny Phlox

Author : James H. Locklear

ABSTRACT Proposed by Linnaeus in 1753, Phlox ovata was a name of long-standing use until Reveal et al. established that an illustration cited in the Linnaean protologue and designated as the type of the species by a later monographer was based on a species from a different family, seemingly rendering P. ovata L. invalid and …

Observations on the Relationship Between Above- and Below-Ground Anthocyanin Production in Galax urceolata (Poir.) Brummitt Growing in Sun-Exposed and Shaded Locations

Author : Howard S. Neufeld

Additional Authors : Derick B. Poindexter, Paula F. Murakami Paul G. Schaberg

ABSTRACT Galax urceolata (Diapensiaceae) is a common evergreen herb of southern Appalachian forests. During the fall and winter, leaves of plants in high light produce substantial amounts of anthocyanins. Oddly, rhizomes in these plants also accumulate anthocyanins. The purpose of this observational study was to identify seasonal trends in anthocyanin production in above- and below-ground …

Canopy Disturbance Patterns in Secondary Hardwood Stands on the Highland Rim of Alabama

Author : Justin L. Hart

Additional Authors : Arvind A.R. Bhuta, Rebecca M. Schneider

ABSTRACT Disturbance regimes of many hardwood forests of the eastern United States in the complex stage of development are characterized by localized canopy disturbance events that change fine-scale biophysical conditions. Recently, research has demonstrated the importance of gap-scale disturbance processes in secondary hardwood stands of the southern Appalachian Highlands. However, information on canopy disturbance patterns …

Seed Germination of Habenaria repens (Orchidaceae) in situ Beyond its Range, and its Potential for Assisted Migration Imposed by Climate Change

Author : Brian G. Keel

Additional Authors : Lawrence W. Zettler Beth A. Kaplin

ABSTRACT All orchids require free-living, mycorrhizal fungi to complete their life cycles in nature and consequently, orchid conservation must take into account both organisms. In light of climate change now underway, orchids and other plants must be capable of migrating to higher latitudes, either on their own or with human intervention (5assisted migration). In this …

Genetic Variation and Population Structure of Arabidopsis lyrata ssp. lyrata (Brassicaceae) along the Eastern Seaboard of North America

Author : Michael W. Lloyd

Additional Authors : Bernadette Roche, Roland P. Roberts

ABSTRACT Arabidopsis lyrata ssp. lyrata is widespread but edaphically restricted, which suggests that the dispersal ability and level of genetic exchange among populations might be limited. We assessed levels of genetic diversity and population differentiation within and among six A. lyrata ssp. lyrata populations from along the eastern seaboard of the United States by examining …
