The emerald ash borer is causing dramatic losses following its introduction into North America, with hundreds of millions trees killed. Attacked lose wood integrity rapidly after infestation and are prone to failure. aim this study was investigate the degrading potential Basidiomycota fungi previously found associated EAB galleries. Laboratory soil agar microcosm experiments showed that many wh...
The objectives of the paper had been to evaluate level at which weathering, as main process active in studied soil, proceed modelling soil vital environment. 
 researches performed Patranjeni area, located ApuseniMountains, on an AlosolRodic. results pointed out that general background extremely anthropic polluted and acid (pH below 4.5), micromorphological observation (on oriented thin se...
Natural and anthropogenically induced soil erosion can cause serious loss of the archaeological record. Our work shows value multi-scalar geoarchaeological study when excavating re-excavating rockshelters in a highly dynamic sedimentary environment where is prominent. Here we present our on Kisese II rockshelter, Tanzania, originally excavated 1950s largely unpublished, that preserves an import...
Understanding the development of calcic and petrocalcic horizons is important for palaeoclimate reconstruction. The micromorphology and geochemistry of Quaternary calcic and petrocalcic horizons formed in the area around Coimbatore, Tamil Nadu are discussed. The calcic horizons represent the Bk horizons that occur as thick complex profiles ( 300 cm thick) in the foothill regions while the lamin...
Investigation of paleosols plays a great role in paleoecological and paleoclimatological studies. They are also important in soil survey and planning, as they exhibit characteristics different from younger soils. Paleosols are those soils which formed under conditions different from present ones, and are either buried within sedimentary sequences or those which lie on persisting surfaces. Altho...
studying forest degradation through evaluation of soil nutrient concentrations, which reveals soil functioning within the ecosystem, is necessary for sustainable management of land resources. this research was conducted to understand the changes of soil nutrient, resulting from exploitive management using some soil features and their spatial pattern. in the mid-summer of 2014, two sites were se...
Gypsiferous Aridisols are of great importance and extent in arid and semi-arid environments. There is a close relationship between soil genesis and landscape positions. This study aimed to determine the genesis and classification of gypsiferous soils and to investigate the relationship between micro-and macro-morphology of gypsum crystals and geomorphic positions in Rafsanjan area. The study ar...
