Initiation Of Terpenoid Synthesis In Osmophores Of Stanhopea Anfracta (Orchidaceae): A Cytochemical Study, Kenneth J. Curry

Faculty Publications

The terpenoid component of the osmophore fragrance in Stanhopea species is composed of isoprene units synthesized via the mevalonic acid pathway. Localization of hydroxymethylglutaryl CoA synthase in the pathway was achieved using a technique which elicits the formation of an electron- dense precipitate of uranyl ferrocyanide at the point where an acetyl group from acetyl CoA is transferred to acetoacetyl CoA, releasing free CoA-SH. Applying this technique to cells of the osmophore of S. anfracta resulted in a precipitate between the inner and outer mitochondrial membranes, in the smooth endoplasmic reticulum, and, to a lesser extent, on the outer surface …

Osmophores Of Stanhopea (Orchidaeceae), William Louis Stern, Kenneth J. Curry, Alec M. Pridgeon

Faculty Publications

Species of the Neotropical orchid genus Stanhopea produce a fragrance comprising terpenoids and aromatics which attracts euglossine bee pollinators. The secretory tissue, called an osmo- phore, is located in the adaxial region of a sac formed near the proximal portion of the floral lip. This region is easily recognized in Stanhopea oculata and S. wardii because it is papillate. The osmophore in these two species includes all the cells of the papillae and those directly below, that grade into fundamental tissue. Osmophore cells are more densely cytoplasmic than cells in the adjacent tissue. Numerous amyloplasts and mitochondria are seen in …

Distribution Of Vertebrates Of The Bighorn Canyon National Recreation Area, Stanley H. Anderson, Wayne A. Hubert, Craig Patterson, Alan J. Redder, David Duvall

Great Basin Naturalist

During a survey of the vertebrates in the Bighorn Canyon National Recreation Area, 46 mammal, 210 bird, 9 reptile, 5 amphibian, and 28 fish species were found. Habitat structure and moisture were two environmental variables associated with species numbers across this 1,820-ha area. Eight distinct habitats were evaluated. In coniferous forests, 27% of the birds and 54% of the mammals were observed. Sagebrush/grasslands and upland shrublands were very arid and had relatively few vertebrates. Five introduced game birds occurred in sagebrush habitat. Riparian and wetland habitats had the largest number of unique vertebrates, 38 and 77 respectively. The establishment of …

Abundance And Distribution Of Herbaceous Angiosperms In Grass-Sedge Marshes Of West-Central Florida: The Effect Of Seasonal Water-Level Fluctuation, Pamela S. Botts

USF Tampa Graduate Theses and Dissertations

Grass-sedge marshes in west-central Florida were studied to determine the abundances and distributions of herbaceous angiosperms. Cluster analysis, reciprocal averaging, and a biotic boundaries technique were used to analyze the relationship between community composition and depth within the marsh. Shallow areas were dominated by Rhynchospora filifolia, Dichanthelium sabulorum, and Rhynchospora cephalantha. Abundances of the species fluctuated seasonally and varied between marshes. Deep areas of individual marshes differed markedly from shallow areas and from each other. A deep, well-drained marsh supported a monospecific stand of Juncus repens, while a less deep, but poorly drained marsh had a …
