TL;DR: The Madrean Archipelago or Sky Islands region of the southwestern United States and northern Mexico is recognized for its unique biological diversity, natural beauty, and cultural heritage as discussed by the authors, and a 2012 conference brought together scientists, managers, students, and other interested parties from the United states and Mexico to share their knowledge and passion about the region and to identify needs and creative solutions for existing and emerging problems.

TL;DR: In this paper, a Symposium focused on technologies that bridge the gap between research and its application in the management of woodlands is presented, focusing on ecology and silvicutural practices; growth, yield, and utilization potentials; livestock and grazing practices; wildlife habitat and values; and hydrology and watershed management.

TL;DR: In this article, the effects of forest management can be predicted from forest inventory data and the development of snow runoff forecasting procedures and computer simulation models of forest snowpack dynamics, as well as increasing the general knowledge of snow hydrology.

TL;DR: The diversity of uncultured Frankia populations in root nodules of Alnus oblongifolia trees geographically isolated on mountaintops of central Arizona was analyzed by comparative sequence analyses of nifH gene fragments and microdiversity was demonstrated and partitioning of diversity by site suggested.
