Four bacterial strains were isolated from the fly larvae of an obligate parasitic fly, Wohlfahrtia magnifica (Diptera: Sarcophagidae). These isolates were characterized by a polyphasic approach and represent a new lineage of gamma-Proteobacteria as their closest relative is Xylella fastidiosa (87.1% 16S rDNA similarity). The four strains are identical at the 16S rDNA level, the level of similar...

Several parameters of flowering stems of two cultivars of protea Leucospermum cordifolium (Knight) Fourc (‘Succession II’ and ‘Tango’) and one of protea Protea L. (Protea susannae x magnifica ‘Susara’) were studied in different commercial plantations. These included length and weight measures, nutrient concentrations of detached parts (flower heads, leaves and stems), and removal of nutrients o...

Botryosphaeria spp. occur on and cause diseases of Proteaceae, but accurate identification has been problematic due to the lack of clear species circumscriptions of members of this genus. In this study, 46 isolates of Botryosphaeria from proteaceous hosts growing in various parts of the world were studied, using morphology, cultural characters and sequence data from the ITS region of the rDNA o...

PREMISE OF THE STUDY Despite the extensive phenotypic variation that characterizes the Gesneriaceae family, there is a lack of genomic resources to investigate the molecular basis of their diversity. We developed and compared the transcriptomes for two species of the Neotropical lineage of the Gesneriaceae. METHODS AND RESULTS Illumina sequencing and de novo assembly of floral and leaf sample...

This study was carried out to determine the role of non-biting cyclorrhaphan flies as carriers of human intestinal parasites at Woreta, northwestern Ethiopia. In total, 6530 flies were collected from four breeding sites and then examined for human intestinal parasites, mainly using the formol-ether concentration method. Fly species identified were Musca domestica (32.9%), Chrysomya rufifacies (...

4 Corresponding author: charles_van_riper@ usgs.gov; 520-491-0721 ABSTRACT: We studied great gray owls (Strix nebulosa Forster) in Yosemite National Park, California, measuring variables that could potentially influence patterns of occurrence and conservation of this stateendangered species. We found that owl presence was closely tied to habitat (red fir (Abies magnifica A. Murray) and the abun...

Sarcodes sanguinea is a nonphotosynthetic mycoheterotrophic plant that obtains all of its fixed carbon from neighboring trees through a shared ectomycorrhizal fungus. We studied the spatial structuring of this tripartite symbiosis in a forest where Sarcodes is abundant, and its only fungal and photosynthetic plant associates are Rhizopogon ellenae and Abies magnifica, respectively. We found dis...

We compared abundances of seven species of forest rodents among three types of fir (Abies concolor and A. magnifica) forest: unlogged old-growth, unlogged mature, and shelterwood-logged old-growth. Small mammals were livetrapped during summers 1991 and 1992 in four grids within each type of forest; grids were located in the Lassen National Forest in northeastern California. Shelterwood-logged f...
