A networking resource devoted to biological soil crusts and the researchers who study them. We will provide a means for international scientists to communicate, share their research, share important news and announcements, ask questions and find collaborators. We will also provide a space for informal writing on research, opinion, and ideas (now seeking posters!).

Biological Soil Crusts: The Role of Trampling, Climate Change and Nitrogen Deposition in Affecting Community Species Composition
A PhD-level position is available at the University of Nevada, Las Vegas, to study the species dynamics of biological soil crusts communities. The successful candidate will work on a collaborative project that will examine the natural dynamics in undisturbed communities, as well as how trampling (from both cattle and people), climate change (experimentally manipulations with heating lamps and watering treatments), drought (using rainout shelters), fire, and nitrogen deposition is or has affected the composition of biological soil crusts communities. These studies will occur on both the Colorado Plateau and in the Mojave Deserts. This position will: 1) sample current and past experiments to assess treatment effects and recovery from those treatments; 2) synthesize 15 years of data on the natural dynamics of biological soil crust communities in undisturbed areas of both the Colorado Plateau and the Mojave Deserts; 3) effectively use statistical analyses to assess effects, and 4) communicate results in presentations and peer-reviewed publications. This project offers an unparalleled opportunity to examine how species composition of biological soil crusts changes through time, as we have the longest existing data set in the world. This position will also revisit some sites and examine how treatments have affected biocrust cover and physiology, using a portable fluorometer. A background in laboratory and field methods in ecology, physiology, and/or biogeochemistry is preferred. This position will be working with Drs. Henry Sun (Desert Research Institute in Las Vegas, NV) and Jayne Belnap (USGS, Canyonlands Research Station in Moab, UT). Salary is $1800/month. Start date will be fall 2014 or spring 2015, depending on the application date. Position is expected to last 4 years. Interested individuals should submit a cover letter, curriculum vitae, and three references to Dr.
Henry Sun (henry.sun@dri.edu).

  1. This is interesting about the Nitrogen disposits in the wild from air and rain which appears to be a global phenomena and many are researching this effect on various plant communities like Chaparral and grassland prairies & Savannas which are both degrading. The ONLY thing that is benefited in an abnormal way are weeds or many ruderals which thrive on a higher nutrient and create a bacteria system as oppose to the mycorrhizal one, which also in of itself dislikes a high fertility content. This all has to do with Nations around the globe growing their precious economies which in turn keeps them elected. Unfortunately, none of them have the guts to put the brakes on this disrespect for the natural world and neither do the Corporate Scientists who receive their pay cheques from the same source.
