Genomic Prediction of Biomass Yield in Two Selection Cycles of a Tetraploid Alfalfa Breeding Population.
Xuehui Li,Yanling Wei,Ananta Acharya,J. L. Hansen,Jamie Crawford,D. R. Viands,Réal Michaud,Annie Claessens,E. Charles Brummer +8 more
TL;DR: Evidence is provided that GS can accelerate genetic gain in alfalfa for biomass yield and the selection efficiency per unit time for GS is higher than phenotypic selection, although accuracies will likely decline across multiple selection cycles.

Rapid Assessment of the Nutritional Value of Foods Eaten by Mountain Gorillas: Applying Near-Infrared Reflectance Spectroscopy to Primatology
Jessica M. Rothman,Colin A. Chapman,Colin A. Chapman,J. L. Hansen,Debbie J. R. Cherney,Alice N. Pell +5 more
TL;DR: NIRS offers a rapid and cost-effective means of analysis of tropical leaves and herbs, and has the potential to transform primate feeding ecology studies by allowing us to evaluate the importance of intraspecific variation in nutritional value.

Michael D. Casler,Kenneth P. Vogel,J. A. Balasko,John D. Berdahl,D. A. Miller,J. L. Hansen,J. O. Fritz +6 more
TL;DR: Of these cultivars, Lincoln was the most widelyprivate breeders, presumably due to its superior performance in regional trials (Thomas et al., 1958).

TL;DR: In this paper, a field-scale study was conducted to develop realistic yield and cost estimates for diverse regions of the USA, where switchgrass response to fertility treatments (0, 56, and 112 kg N−1) and corresponding estimates of production costs for sites with diverse soil and climatic conditions were evaluated.
Impacts of nitrogen fertilization rate and landscape position on select soil properties in switchgrass field at four sites in the USA

TL;DR: In this paper, the impacts of applying nitrogen fertilization and landscape position on soil properties in switchgrass fields at multiple locations in the USA were evaluated and shown that the high N rate averagely increased NO3−-N by 75.7% for the two depths and three sites.
