Seed Production and Germination of Penstemon oklahomensis Pennell (Plantaginaceae), a Southern Great Plains Endemic

Author : Jennifer A. Messick

Additional Authors : Bruce W. Hoagland

ABSTRACT We investigated the seed production and germination requirements of Penstemon oklahomensis, a species of conservation concern, to determine interannual variation in seed production and germination requirements. Mature seed capsules were collected and seed numbers counted in two successive years to assess interannual variation in seed production. A significant difference in number of seeds produced …

Propagation by Cuttings of the Federally Threatened Apios priceana (Fabaceae)

Author : Nathan J. Paris

Additional Authors : Jennifer M. Cruse-Sanders Robert S. Boyd

ABSTRACT Apios priceana (Fabaceae) is a rare herbaceous perennial vine. Seed collection for ex situ conservation is difficult because seed production is sporadic. We investigated propagation by cuttings of A. priceana at Redstone Arsenal, Alabama. Two experimental factors were investigated: donor plant size (small vs. large) and month of cutting (May vs. June 2013). We …

Indirect Effects of Landscape Spatial Structure and Plant Species Richness on Pollinator Diversity in Ozark Glades

Author : Shannon N. Grover

Additional Authors : Jesse E. D. Miller, Ellen I. Damschen

ABSTRACT: Changes in landscape spatial structure—specifically, reductions in habitat area and connectivity—are thought to be a primary cause of pollinator declines across North America. However, the mechanisms by which landscape structure influences pollinator diversity are not well understood. Because flowering plants and pollinators are generally mutualistic, the impact of landscape structure on one can influence …

Ectomycorrhizal Fungi Associated with American Chestnut at a Site in Tennessee, USA

Author : Steven L. Stephenson

Additional Authors : Mourad Ben Hassine Ben Ali, Adam W. Rollins, M. Steven Furches, Karl R. Atherton
