“…Weathering and secondary mineralogy of basalt in these environments have been characterized using broad precipitation-mineralogy relationships (Barshad, 1966;Alexander et al, 1993). However, these relationships overlook the complex interactive control of temperature and precipitation on weathering and secondary phase stability.…”

“…7A) (Condon et al 2011;Davies et al 2012;Chambers et al 2014;Chambers et al in press). Higher precipitation and cooler temperatures, coupled with greater soil development and plant productivity at mid to high elevations, can result in greater resources and more favorable environmental conditions for plant growth and reproduction (Alexander et al 1993;Dahlgren et al 1997). In contrast, minimal precipitation and high temperatures at low elevations result in lower resource availability for plant growth (West 1983a,b; Figure 6.…”

This Report provides a strategic approach for conservation of sagebrush ecosystems and Greater SageGrouse (sage-grouse) that focuses specifically on habitat threats caused by invasive annual grasses and altered fire regimes. It uses information on factors that influence (1) sagebrush ecosystem resilience to disturbance and resistance to invasive annual grasses and (2) distribution, relative abundance, and persistence of sage-grouse populations to develop management strategies at both landscape and site scales. A sage-grouse habitat matrix links relative resilience and resistance of sagebrush ecosystems with sage-grouse habitat requirements for landscape cover of sagebrush to help decision makers assess risks and determine appropriate management strategies at landscape scales. Focal areas for management are assessed by overlaying matrix components with sage-grouse Priority Areas for Conservation (PACs), breeding bird densities, and specific habitat threats. Decision tools are discussed for determining the suitability of focal areas for treatment and the most appropriate management treatments.

“…In this respect, it would be rather difficult to interpret the precise effect of the canopy on the clay mineral contents. Similarly, Alexander et al (1993), Watanabe et al (2004), Mareschal (2008), Graham and O'Geen (2010), and Baker (2010) The Ah horizon of profile RP 1 consisted of well-preserved root remnants/residues in the aggregates/MSUs coated by biofilms (Figure 3a). The root remnants/residues in this horizon surrounding the aggregates/MSUs form the individual grains and smaller microaggregates together by interwoven and curled masses of roots (Figure 3b).…”

Plant species exert differential effects on soil mineralogical and micromorphological characteristics. The effect of red pine and oak tree roots on the mineralogical and micromorphological characteristics of rhizosphere soils in two sampling sites in the Göksu catchment was studied. The climate, topography, and bedrock conditions were kept consistent, whereas the plant factor was kept as the only variable in each site. Rhizosphere soils under the canopies of 100 years old and naturally occurring trees were compared via macromorphology, submicroscopy, mineralogy, and physical and chemical properties. The soils of red pine (RP 1 and RP 2 profiles) were determined to have higher porosity when compared to the soils of the oak tree profiles (Ok 1 , Ok 2 ). However, the higher amounts of welded/cemented aggregates in the Ok 1 and Ok 2 profiles were probable indicators of maturity and probable stability of the aggregates/ MSUs. The dominant clay mineral in sampling site 1 was kaolinite, whereas it was smectite in sampling site 2.
