Biological Soil Crusts (BSCs) are organosedimentary assemblages comprised of microbes and minerals in topsoil of terrestrial environments. BSCs strongly impact soil quality in dryland ecosystems (e.g., soil structure and nutrient yields) due to pioneer species such as Microcoleus vaginatus; phototrophs that produce filaments that bind the soil together, and support an array of heterotrophic microorganisms. These microorganisms in turn contribute to soil stability and biogeochemistry of BSCs. Non-cyanobacterial populations of BSCs are less well known than cyanobacterial populations. Therefore, we attempted to isolate a broad range of numerically significant and phylogenetically representative BSC aerobic heterotrophs. Combining simple pre-treatments (hydration of BSCs under dark and light) and isolation strategies (media with varying nutrient availability and protection from oxidative stress) we recovered 402 bacterial and one fungal isolate in axenic culture, which comprised 116 phylotypes (at 97% 16S rRNA gene sequence homology), 115 bacterial and one fungal. Each medium enriched a mostly distinct subset of phylotypes, and cultivated phylotypes varied due to the BSC pre-treatment. The fraction of the total phylotype diversity isolated, weighted by relative abundance in the community, was determined by the overlap between isolate sequences and OTUs reconstructed from metagenome or metatranscriptome reads. Together, more than 8% of relative abundance of OTUs in the metagenome was represented by our isolates, a cultivation efficiency much larger than typically expected from most soils. We conclude that simple cultivation procedures combined with specific pre-treatment of samples afford a significant reduction in the culturability gap, enabling physiological and metabolic assays that rely on ecologically relevant axenic cultures.

Scholarly writing is an essential skill for nurses to communicate new research and evidence. Written communication directly relates to patient safety and quality of care. However, few online RN-BSN programs integrate writing instruction into their curricula. Nurses traditionally learn how to write from instructor feedback and often not until midway into their baccalaureate education. Innovative strategies are needed to help nurses apply critical thinking skills to writing. The authors discuss a collaborative project between nursing faculty and technical communication faculty to develop and implement a writing course that is 1 of the 1st courses the students take in the online RN-BSN program.

Take a journey to discover how you can provide quality information to your patrons for free! Explore the world of Open Access Resources! Open Access refers to scholarly information that is free, online, and free of most copyright and licensing restrictions. This makes it easier for people to find and use reliable information on a myriad of subjects, such as health information, educational materials, or business resources. Knowledge of Open Access is important for all librarians to help us best serve our communities and stretch our dwindling budgets. Your tour guides will give an overview of Open Access, discuss legislative issues, demonstrate how to find open access resources, and explain how librarians can get involved.
