Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing
an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed
the genome of M. osmundae, focusing on genes that may provide some insight into its
mode of pathogenicity and reproductive biology.
Mixia osmundae has the smallest plant pathogenic basidiomycete...
Materials based on BiMO₃-modified BaTiO₃ have been shown to exhibit a number of attractive electrical and electromechanical properties. In addition, many of the materials in this broad family exhibit reduced sintering temperatures for densification as compared to pure BaTiO₃. We report here a study of the phase evolution and sintering...
Non-prescription stimulant use is a high-risk behavior prevalent in the college population. To date, research on this substance use behavior lacks a comprehensive theoretical lens, as well as geographical diversity. Guided by the Theory of Triadic Influence (TTI), multilevel (i.e. students within schools) modeling was used to analyze survey data...
Coastal environments are characterized by complex feedbacks between flow, sediment transport, and morphology, often resulting in the formation of nearshore sandbars. In many locations, such as Hasaki (Japan), the Netherlands, and the Columbia River Littoral Cell (CRLC, USA), these sandbars exhibit a net offshore migration (NOM) cycle whereby these features...
1. Freshwater mussels (Order: Unionidae) are among the most imperiled aquatic organisms in North America. Conservationists and resource managers within the United States are increasingly advocating restoration of these animals to preserve biodiversity and boost ecosystem services in the nation’s waterways. 2. Historically, restoration methods have yielded less than optimal...
American beautyberry (Callicarpa americana) is a deciduous shrub native to the southeast U. S. and is grown primarily for its metallic-purple fruit that develop in the fall. There are also pink- and white-fruiting and variegated forms but these traits are rare in nature and there is no information available regarding...
In this paper we discuss the application of a range of techniques to the
verification of mission-critical flight software at NASA’s Jet Propulsion Laboratory.
For this type of application we want to achieve a higher level of confidence than can
be achieved through standard software testing. Unfortunately, given the current...
Restoration of exotic annual grass-invaded rangelands is needed to improve ecosystem function and services.
Increasing plant species richness is generally believed to increase resistance to invasion and increase desired
vegetation. However, the effects of species richness and individual plant life forms in seed mixes used to restore
rangelands invaded by...
The spread of medusahead across the western United States has severe implications for a wide range of ecosystem
services. Medusahead invasion reduces biodiversity, wildlife habitat and forage production, and often leads to
increased fire frequency and restoration costs. Medusahead is problematic in the Intermountain West and California
Annual Grasslands. The...
The genetic structure of adult codling moth, Cydia pomonella (L.), populations was characterized both inside a managed apple, Malus domestica Borkdhausen, orchard and in surrounding unmanaged hosts and nonhost trees in central Chile during 2006–2007. Adult males were collected using an array of sex pheromone-baited traps. Five microsatellite genetic markers...
