Reseeding efforts are routine in the Great Basin. While they are necessary to combat the losses of flora in the region, the have failed to address the demand for native legumes. Legumes add nitrogen to the soil, provide a valuable source of food for foragers, and can sustain pollinators. The high cost yet low quality of available legumes and lack of experience in reseeding efforts have been blamed for their absence.
In a study partially funded by the Great Basin Restoration Initiative, scientists at the USDA-ARS Forage and Range Research Lab made 20 collections of Searls prairie clover in an attempt to characterize their potential for agronomic seed production, flowering date and biomass, inherent population relationships, and phenotypic correlation with climate conditions at the collection sites.
The analysis of data gathered at the collection sites found tremendous variation in the observed traits within and among the populations. Nevertheless, researchers discovered that precipitation amounts were related to the potential seed yield and biomass. From this data, seed release strategies were developed and will soon be implemented first at a site in northwestern Utah followed by others.
Shaun Bushman, the author of the study, explained, “This study is paving the way toward agronomic seed production in Searls prairie clover by identifying populations and traits that must be considered for economical and efficient seed production. Additionally, it will allow for germplasm releases to target environments and demographic histories of this species such that the plants will be used in locations to which they are likely adapted. Germplasm development and further studies concerning agronomic practices are underway.”
Results from the study are published in the April 2011 issue of Crop Science.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
