Disturbance can fragment plant clones into different sizes and unstabilize soils to different degrees, so that clonal fragments of different sizes can be buried in soils at different depths. As a short-term storage organ, solon internode may help fragmented clones of stoloniferous plants to withstand deeper burial in soils. We address (1) whether burial in soils decreases survival and growth of...
Mild steel coupons (MSCs) buried for thirty months in soils inoculated with bacterial isolate Bacillus cereus-SNB4 resulted in microbiologically influenced corrosion (MIC) based average percent weight loss (APWL) and corrosion rate (CR) as 8.21% and 3.55mgdm d , respectively with 18.86% moisture and 2 1 0.218% organic contents. For nutrient added soils the corresponding figures were -8.95 and -...
Survival of sclerotia of Sclerotinia minor and S. sclerotiorum was compared in irrigated fields during the summer in two major lettuce production areas in California. More than 50% sclerotia of S. sclerotiorum compared with 4 and 35% of S. minor remained viable after 24 weeks of burial at 15 and 5 cm depths, respectively, in the San Joaquin Valley while >80% of sclerotia survived in the Salinas...
Small mammals were sampled at two waste burial sites (Sites 1 and 2) at Area G, TA-54, and a control site outside Area G (Site 3) to identify radionuclides that are present within surface and subsurface soils at waste burial sites, to compare the amount of radionuclide uptake by small mammals at waste burial sites to a control site, and to identify the primary mode of contamination to small mam...
Field and laboratory data combined with geochronological information were used to investigate the nature and rates of pedogenesis of three late Holocene soils at the Lubbock Lake archaeological site (Southern High Plains of Texas). A variety of pedologic characteristics become better expressed with time, and aerosolic additions and burial of the soils significantly affect the development of the...
Decomposition of plant residues is largely mediated by soil-dwelling microorganisms whose activities are influenced by both climate conditions and properties of the soil. However, a comprehensive understanding of their relative importance remains elusive, mainly because traditional methods, such as soil incubation and environmental surveys, have a limited ability to differentiate between the co...
An unidentified environmental reservoir of infectivity contributes to the natural transmission of prion diseases (transmissible spongiform encephalopathies [TSEs]) in sheep, deer, and elk. Prion infectivity may enter soil environments via shedding from diseased animals and decomposition of infected carcasses. Burial of TSE-infected cattle, sheep, and deer as a means of disposal has resulted in ...
Wireless Underground Communication Networks (WUCNs) consist of wireless devices that operate below the ground surface. These devices are either (i) buried completely under dense soil, or (ii) placed within a bounded open underground space, such as underground mines and road/subway tunnels. The main difference between WUCNs and the terrestrial wireless communication networks is the communication...
As an object of research, the technological process cutting roots stalks pine tree with soil and placing them on side together spherical disk in combined aggregate implementation was accepted. In our republic's cotton cultivation field, world's latest innovations, including minimal, resource-saving, Strip-till, No-till technologies drip irrigation methods, are gradually being introduced. Combin...
Taphonomy is the study of many variables involving decomposition, preservation, dispersal, erosion, burial or exposition of dead organisms. Forensic Taphonomy examines how biotic or abiotic variables can change evidences in legal investigations. Many insects are closely associated with decomposition processes. The scavenger dung-beetle, Coprophanaeus lancifer (Linnaeus, 1767), may be important ...
