The isolation and structure of leptosphaerin : a metabolite of the marine ascomycete, Leptosphaeria oraemaris (Linder) and A synthesis of the marine toxin, 9-isocyanopupukeanane

Creator:: Schiehser, Guy Alan
Abstract:: The ethyl acetate extract of the culture filtrate of the marine Ascomycete, Leptosphaeria oraemaris (Linder) yielded a novel metabolite designated by the common name leptosphaerin. An x-ray crystallographic structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)- 3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine 47 and D-mannitol 44. Oxidation of 47 followed...

A preliminary classification of forest communities in the central portion of the western Cascades in Oregon

Creator:: Dyrness, C. T., Franklin, Jerry F., Moir, William H., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Forest communities in the central portion of Oregon's western Cascades are arrayed along moisture and temperature gradients. With the aid of reconnaissance data and a computerized ordination technique, 23 forest communities have been provisionally recognized in two distinct forest zones, the Tsuga heterophylla (300 to 1050 m in elevation) and...

Sulfation of fucoidan in Fucus embryos and its possible role in localization

Creator:: Crayton, Michele Allen
Abstract:: Under defined cultural conditions, zygotes of the brown alga Fucus distichus L. Powell divide synchronously to form two-celled embryos at approximately 24 hours after fertilization. These two cells differ from one another in gross morphology, ultrastructure, cytochemistry, and developmental fate. Cytochemical staining and autoradiography indicated that a sulfated polysaccharide was...

Relationships between vegetation and terrain variables in southeastern Arizona

Creator:: Mouat, David A.
Abstract:: A study to determine the relationship between plant species and eight terrain variables and between thirty-one vegetation types and the terrain variables was conducted in a 4, 000 square mile area south and east of Tucson, Arizona. The eight terrain variables included elevation, parent material, macrorelief, landform type, drainage density,...

The development and maturation of the Elaiosome of Dicentra formosa (Andr.) Walp

Creator:: Barnes, April E. Hootman
Abstract:: The developmental cytology of the elaiosome of Dicentra formosa (Andr.)Walp. was investigated from the time of initial differentiation until complete maturation. Light and transmission electron microscopy studies showed that the elaiosome becomes differentiated from epidermal tissue in the prefertilized ovule. At this time the cells are characterized by their large...

Morphology, ultrastructure and mating of sporidia of a wheat-bunt fungus, Tilletia caries (DC.) Tul.

Creator:: Kollmorgen, James Frederick
Abstract:: The teliospore of Tilletia caries germinates to produce a promycelium with a whorl of primary sporidia at its tip. The time between emergence of the promycelium and the development of primary sporidia averaged 2.3 h. Fusion between compatible sporidia occurred within an additional 3.8 h. Primary sporidia appeared to be...

A preliminary vegetation classification of the Tombstone, Arizona, vicinity

Creator:: Garcia-Moya, Edmundo, 1941-
Abstract:: The need for classifying vegetation in a more precise way is evident. Also, there is a need to provide a hierarchical classification scheme that will match changes in image characteristics as one moves through the scales from space to conventional aerial photography. Such refined classifications of vegetation are the first...
