The study of the infra-specific ranks (i.e., subspecies and variety) can be considered
the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker
(Fabaceae) is the most taxon rich species in the U.S. flora currently including 40
taxonomic varieties. These varieties were described using traditional taxonomic
methods primarily...
Production of 89Zr serves as a crucial preliminary step for exploring Zr-chelates, determining their stability constants, and advancing radiolabeling methodologies for monoclonal antibody based theranostics. 89Zr is typically produced by the irradiation of natural yttrium targets, a process extensively documented in scientific literature. Two primary methods are employed: the 89Y(p,n)89Zr...
The inhibition of the enolase enzyme system by fluoride has
been established for many years in in vitro experiments; however,
this inhibitory action has never been demonstrated in an intact mammal.
The present work was designed to examine the effect of fluoride
administered by intravenous infusion in rats, under the...
Nursery plants are important vectors for plant pathogens. Understanding what pathogens occur in nurseries in different production stages can be useful to the development of integrated systems approaches. Four horticultural nurseries in Oregon were sampled every 2 months for 4 years to determine the identity and community structure of Phytophthora...
Recent state and national standards have increased the interest in engineering at the K-12 level. Science standards, in particular, have begun to make the case for including engineering throughout the K-12 scope of study. Despite the increased attention to engineering, the characteristics and uniqueness of the field of engineering are...

Phytophthora infestans, the cause of the devastating late blight disease of potato and tomato, exhibits a clonal reproductive lifestyle in North America. Phenotypes such as fungicide sensitivity and host preference are conserved among individuals within clonal lineages, while substantial phenotypic differences can exist between lineages. Whole P. infestans genomes were...
• Premise of the study: The dramatic advances offered by modern DNA sequencers continue to redefine the limits of what can be accomplished in comparative plant biology. Even with recent achievements, however, plant genomes present obstacles that can make it difficult to execute large-scale population and phylogenetic studies on next-generation...

Genetic factors such as decreased genetic
diversity and increased homozygosity can have detrimental
effects on rare species, and may ultimately limit potential
adaptation and exacerbate population declines. The Gulf
and Atlantic Coastal Plain physiographic region has the
second highest level of endemism in the continental USA,
but habitat fragmentation and...
