Today’s Mediterranean landscapes result from the interaction between ecosystems and anthropogenic activities. This study aims to assess how land-use changes mid-nineteenth end of twentieth century influenced temporal continuity in central Apennines (central Italy). Information was acquired Gregorian cadastral maps, orthophotos aerial photos (1850, 1954, 1980 2010), digitised georeferenced using...

There are places in our planet where environmental conditions beyond normal limits for growth but still harbour life. Extremophile microalgae the candidates large-scale production because (i) their extreme help to avoid unwanted contaminations, facilitating and (ii) order survive under harsh environments, these microorganisms synthesise valuable uncommon biomolecules. include Arthrospira platen...

Conflicts between crop farmers and pastoralists have become a common feature of economic livelihood in West Africa. The study assessed the demographic implications farmers-pastoralists conflict Benue North-West, Nigeria. adopted cross-sectional survey design sample 120 respondents was purposively selected from three LGAs mostly affected by pastoralists’ attacks. Data were collected using struct...

The research aims to study and analyze the physical-mechanical technological properties of eroded soils in Uzbekistan. data on susceptibility water erosion sloping lands is presented. average monthly indicators precipitation over last ten years Uzbekistan are analyzed. results determining moisture, density, hardness soil slopes It has been established that with traditional technology tillage ot...

We consider whether current notions about superstring theory below the Planck scale are compatible with cosmology. We find that the anticipated form for the dilaton interaction creates a serious roadblock for inflation and makes it unlikely that the universe ever reaches a state with zero cosmological constant and time-independent gravitational constant. Superstring theories have been extensive...

Saturated hydraulic conductivity (Ksat) is a key soil parameter for representing infiltration and drainage in land surface models. For large scale applications, Ksat often estimated from pedotransfer functions (PTFs) based on easy-to-measure properties like texture bulk density. The reliance of PTFs data uniform arable lands the omission structure limits applicability texture-based predictions ...

Soil organic carbon (SOC) and nitrogen (N) contents are controlled partly by plant inputs that can be manipulated in agricultural systems. Although SOC and N pools occur mainly in the topsoil (upper 0.30 m), there are often substantial pools in the subsoil that are commonly assumed to be stable. We tested the hypothesis that contrasting long-term management systems change the dynamics of SOC an...

The Czech landscape has undergone various changes over the last 100 years and been mainly adapted agriculturally for economic purposes. This resulted, among other things, in reservoirs being clogged with sediment. Vrchlice Reservoir was built 1970 to supply drinking water around 50,000 inhabitants, increased sedimentation detected reservoir recent years. Water erosion sediment transport were mo...
