The oribatid mite genus Cultroribula Berlese, 1908 is represented in Mongolia with six species. Most species of Cultroribula found in Mongolia are inhabitants of litter of various types of forests, soils of steppes and the high mountain alpine zone, but are also commonly found in lichens growing on trees or bare rock and terricolous bryophytes. In this work, two species, Cultroribula altaica sp...

Data for water vapor adsorption and evaporation are presented for a bare soil (sandy loam, clay content 15%) in a southern Spanish olive grove. Water losses and gains were measured using eight high-precision minilysimeters, placed around an olive tree, which had been irrigated until the soil reached field capacity (!0.22 m m). They were subsequently left to dry for 10 days. A pair of lysimeters...

Soil transplant serves as a proxy to simulate climate changes. Recently, we have shown that southward transplant of black soil and northward transplant of red soil altered soil microbial communities and biogeochemical variables. However, fundamental differences in soil types have prevented direct comparison between southward and northward transplants. To tackle it, herein we report an analysis ...

The rapid expansion of deserts in recent decades as a result of human actions combined with climatic changes has highlighted the necessity to understand biological processes in arid environments. Whereas physical processes and the biology of flora and fauna have been relatively well studied in marginally used arid areas, knowledge of desert soil micro-organisms remains fragmentary. The objectiv...

In this article, are analyzed the processes of desertification in Region Planning and Management Waters Macururé Curaçá Rivers. The mapping land use, through photointerpretation images RapidEye, allowed to verify that anthropized Caatinga, Caatinga park Agriculture occupy more than half region show decline vegetation resilience. These areas natural pastures support extensive herds whose overgra...

This research selects two study areas with different urban developments, sizes, and spatial patterns to explore the suitable methods for mapping impervious surface distribution using Quickbird imagery. The selected methods include per-pixel based supervised classification, segmentation-based classification, and a hybrid method. A comparative analysis of the results indicates that per-pixel base...

Although marigold (Tagetes patula) is known to produce allelopathic compounds toxic to plant-parasitic nematodes, suppression of Meloidogyne incognita can be inconsistent. Two greenhouse experiments were conducted to test whether marigold is more effective in suppressing Meloidogyne spp. when it is active rather than dormant. Soils infested with Meloidogyne spp. were collected and conditioned i...

It has been shown that starch can effectively stabilize nanoscale magnetite particles, and starch-stabilized magnetite nanoparticles (SMNP) are promising for in situ remediation of arsenic-contaminated soils. However, a molecular level understanding has been lacking. Here, we carried out XAFS studies to bridge this knowledge gap. Fe K-edge XAFS spectra indicated that the Fe-O and Fe-Fe coordina...

The purpose of this paper is to analyse the impact of surface soil moisture on the spectral reflectance in the optical domain [0.35 15 μm]. This work is based on lab spectral reflectance measurements of bare soils at different moisture contents. Knowledge of surface soil moisture is significant for many applications like trafficability after flood, ground – atmosphere exchanges and plant good h...
