The aim of this research work was to investigate the influence of spruce bark natural bioactive compounds on copper bioaccumulation in rape plant.

Surface energy budget over the grass and the concrete surface

Temperature change according to the surface characteristics result from thermal and dynamic energy variations which are occurred by organic relation of more detailed components. Micrometeorological energy budget in urban area that have various surface scales and feature will offer significant indicator to urban thermal environment analysis and improvement. We observed meteorological variables on the concrete that have highest share in urban and the grass that represent park area in urban. At the same time, we directly observed energy flux components using atmospheric turbulence observation system in winter season.

Heat energy exchange of reed canopy over Goheung bay

Heat energy exchange is very important processes in the coastal wetland ecosystems. We observed and analyzed the net radiation flux, the sensible heat flux, the latent heat flux and the soil heat flux, which are balanced in the heat energy balance, over a reclaimed land covered with reeds at Goheung, where is horizontally plane. The atmospheric turbulence had been measured in order to estimate the heat transfer during 5 intensive observation periods (IOPs).

Established activities and land use classification in Thriassion Plain – Greece with the assistance of satellite images, ground measurements and model results

Already since the beginning of the 20th century, Thriassion Plain has been the area that bore the brunt of the industrialization of Greece through the establishment and operation of a large number of industrial and production units. The focus of the present study is the growth of the number of established activities over time and the consequent change in land use.

Constructed wetlands are complex dynamic ecosystems. Ecosystem-level odeling of the processes that take place in a constructed wetland is a useful tool for understanding wetland function and structure and for making predictions.

Estimation of surface shear strength in semi-arid rangelands of Iran
© Aristotle University of Thessaloniki (6/2009)
Modeling soil erosion and runoff requires accurate estimates of surface soil shear strength. In this study, we investigated the use of artificial neural networks (ANNs) in estimating soil shear strength from measured particle size distribution, topographic attributes, normalized difference vegetation index (NDVI), soil organic carbon (SOC), and CaCO3.

The geographical dimension of agro-environmental indicators: developing a preliminary analysis in a Mediterranean case study
© Aristotle University of Thessaloniki (6/2009)
Rural landscape was rapidly changing in southern Europe during the last years. The abandonment of arable land, urban expansion, and unsustainable use of land resources are examples of growing environmental pressures acting on agro-forestry ecosystems. The linkage between environment and agriculture can be expressed through the functions connected with land quality. Based on this framework, a set of agro-environmental indicators was proposed here in order to assess environmental conditions at various geographical and temporal scales.

Using topography and vegetation attributes for estimation of saturated hydraulic conductivity in semiarid rangelands of Iran
© Aristotle University of Thessaloniki (6/2009)
Topographic (elevation, slope, and aspect) and vegetation attributes are routinely available data from digital elevation models (DEMs) and normalized difference vegetation index (NDVI). The objective of this study was to use topographic and vegetation attributes in addition to soil attributes to develop pedotransfer functions (PTFs) for estimating soil saturated hydraulic conductivity (Ks) in the semiarid rangelands of Iran.

Accumulation of cadmium and lead in the edible parts of the fodder shrub Atriplex halimus L. grown on Cd and Pb contaminated soils
© Aristotle University of Thessaloniki (6/2009)
Cadmium and lead accumulation in above ground edible parts of Atriplex halimus L. which is a widespread C4 xero-halophyte plant in the Mediterranean region, has been investigated, not only for the exploration of its possible use for phytoextraction purposes but mainly for the examination of the possible heath threat that can be caused since saltbushes have been extensively used as livestock fodder reserves in arid and semi-arid counties.

Land degradation due to diapirs in Iran, case study: Hableh-Rood Drainage Basin, East of Tehran
© Aristotle University of Thessaloniki (6/2009)
Different geological characteristics play role in land degradation in Iran which are: 1-The abundance of Neogene evaporitic marly formations around and in desertic depression. These units have had important role in the formation of present landforms, are saline, alkaline and erodible and degrade the quality of water resources as diffuse and widespread sources. 2- The presence of numerous diapirs, some of which are salt domes consisting of halite.
