Abstract: The aim of this study is to determine ecoregions and the effect of ecological properties on natural distribution of Anatolian black pine [Pinus nigra Arnold. subsp. pallasiana Lamb. (Holmboe)] in Turkey. The results suggest that 6 ecoregions exist and climate, parent material, topography, anthropogenic factors, floristic composition, competition are ecological factors that determine the distribution of Black pine in Turkey. But, climatic elements such as precipitation and temperature are the dominant factors. The six ecoregions with different characteristics have been identified and distribution of Anatolian black pine revealed depending on ecological features of each region. Each region has its own characteristics that affect the growth and distribution of black pine. Productive black pine forest are found on the subhumid-semiarid areas receiving humid air mass coming from the seas either on northern or southern coastal mountains of Turkey. The poor and/or lowest productive stands occur in the semiarid parts of Inner Anatolia. Black pine can grow on all material in the semi-arid and sub-humid cold climates, but deep weathered parent materials are the best for growing of black pine.

Abstract: The article discusses the periods of environmental education (EE) developed in connection with international social and global international influences, mainly the effect of the First United Nations Conference on Human environment in Stockholm 1972, the 1992 Earth Summit in Rio de Janeiro and the 2002 Earth Summit in Johannesburg. It pays attention to the impact of the social background and the role of science and pedalogical research on the different stages in the curricular and textbooks development. The school subjects ' contents and educational technologies also evolved towards student-centered interactive education in school and out of school. A system of EE from nursery to postgraduate and lifelong education was developed in 1984 and a great part of it has been introduced in the different educational stages since then. After 1989 more than 132 NGOs and communities on ecology and environmental education were established and many others incorporated environmental education aspects in their activities. Still there are many unsolved problems in EE.

Abstract: Present work investigated the relationship between Chlorophyll (Chl) of phytoplankton biomass, and se surface temperature (SST) of the Black Sea, using Sea-viewing Wide Field -of-view Sensor (SeaWiFS) and Advanced Very High Resolution Radiometer (AVHRR) satellite imagery. Satellite derive ddata could provide information on the amount of sea life present (Brown algae, called kelp, proliferation, supporting new species of sea life, including otters, fish, and various invertebrates) in a given area throughout the world. SST from AVHRR from 1993 to 2008 showed seasonal, annual and interannual variability of temperature, monthly variability Chl from SeaWiFS from 1997 to 2009 has alos been investigated. Chl showed two high peaks for the year 1999 and 2008. The correlation between SST and Chl for the same time has been found to be 60%. Correlation was significant at p<0.05. The information could also be useful in connection with studies of global changes in temperature and what effect they could have on the total abundance of marine life.

Abstract: Coasts are areas that are under the influence of the interaction of the air, water and land and attract attention with the abundance of their natural resources and therefore are subjected to excessive usage. This excessive usage may disturb the sensitive balance of the coast ecosystem. In this study, the changes in Arapciftligi, Poyraz, Dalyan lakes area found in Kocacay delta located in the south coast of Marmara sea was evaluated between the periods of 2000 to 2007 with remote sensing method. These lakes, located on the shores, have a very sensitive naturally dynamic balance and very importance in terms of natural surroundings and the coastal zones management plan. It must be known the change of the lakes mentioned above area according to years. Research and applications have demonstrated the advantages of remote sensing and geographic information system techniques on river, delta, lake, lagoon lake, sensitive areas in a lakeshore, coastal erosion etc. monitoring and management. In the study, we beneited from Erdas and Intergraph-Geomedia 6.1 image processing and GIS, and also from AutoCAD 2007 and NetCAD 4.0 computer-aided design (CAD) software. For 2000, 2001, 2005 and 2007 years (4 number) Landsat-5 TM satellite images belonging to the region were used. As a result of the study, Arapciftligi, Dalyan and Poyraz lake areas, number of islets that are seen in the lakes were given in respect to years. Arapciftligi lake shrank 29.5% in size in the years 2000 and 2007. The fact that the lake continued to get smaller in size even in periods of high precipitation may be due to the sediment flowing from the agricultural fields established close to the lake area. Dalyan and Poyraz lakes lost 60% in terms of their surface area in the years 2000 and 2007. In 2000-2001 periods, Dalyan and Poyraz lakes increased in size by 3.2%. The reason for this could be the excessive precipitation and the fact that the seawater from Marmara sea seeps into the lake. Protection of the natural balance of the lagoons can be possible by using a monitoring programme to be set in connection with a healthy, systematic and manageable data system.

Abstract: Variations in lake evaporation have a significant impact on the energy and water budgets of lakes. Understanding these variations and the role of climate is important for water resources management as well as predicting future changes in lake hydrology as a result of climate change. This study presents a comprehensive, 10-year analysis of seasonal, intraseasonal, and interannual variations in lake evaporation for Lake Nasser in South Egypt. Meterological and lake temperature measurements were collected from an instrumetned platform (Raft floating weather station) at 2 km upstream of the Aswan High Dam. In addition to that, radiation measurements at three locations on the lake: Allaqi, Abusembel and Arqeen (respectively at 75, 280 and 350 km upstream of the Aswan High Dam) are used. The data were analyzed over 14-day periods from 1995 to 2004 to provide bi-weekly energy budget estimates of evaporation rate. The mean evaporation rate for lake Nasser over the study period was 5.88 mm day-1, with a coefficient of variation of 63%. Considerable variability in evaporation rates was found on a wide range of timescales, with seasonal changes having the highest coefficient of variation (32%), followed by the intraseasonal (28%) and interannual timescales (11.6%; for summer means). Intraseasonal changes in evaporation were primarily associated with synoptic weather variations, with high evaporation events tending to occur during incursions of cold, dry air (due, in part, to the thermal lag between air and lake temperatures). Seasonal variations in evaporation were largely driven by temperature and net energy advection, but are out-of-phase with changes in wind speed. On interannual timescales, changes in summer evaporation rates were strongly associated with changes in net energy advection and showed only moderate connections to variations in temperature or humidity.

Abstract: Increasing non-ecological land use necessitates more efficient using and utilization of land by man. Therefore, in recent years studies on sustainable land use have gained momentum. In this study, temporal change in land use, mainly between years 1940 and 2010, in Asi river delta on Southern Turkey was covered. To this end, in addition to literature, topographical maps and satellite images from year 1940 and after were used. Also, data were collected through field studies and interviews. Collected data were evaluated from geographical viewpoint using Geographical information system (GIS) and Remote sensing (RS) methods. Unplanned settlement in delta has reached levels high enough to threaten agricultural fields. Especially, great tendency shown by Samandag city and the villages around it towards expanding into delta is an indicator of this threat. In addition, uncontrolled sand mining and touristic facilities on the coastline are alos indicators of wrong land use. In future, direction of settlement to slopes around the delta rather than lowlands will be a much more ecological approach.

Abstract: The well-minded impact of light negative air ions on human organism is still under discussion. The measurements of air ions are not widespread in Latvia yet. The paper presents new results of air pollution evaluation in Rezekne city. Measurements of positive and negative air ion concentrations in Rezekne city were taken during the spring, summer and autumn 2009 and during the winter 2010. Measurements were taken by protative air ions counter "Sapfir-3M" in eight different points of Rezekne city thrice a day. The concentrations of positive and negative air ions with mobility factor k>0.4cm2V-1s-1 were measured. Temperature, relative humidity, wind velocity, direction, etc., were also taken into account. The approximate interconnection between ionization and chemical and mechanical air pollution in relation with meterological conditions was analyzed. The highest level of air ion concentration was observed in mornings, whereas in afternoons this concentration level decreased due to the growth of anthropogenic air pollution in the city, as light air ions, because of their charge, promoted the coagulation and the settlement of pollution particles. This regularity is typical for summer, whereas in spring, autumn and winter it is not characteristic. The unipolarity factor was usually less than 1 in mornings, but usually larger than 1 in afternoons especially in the most polluted city areas where minor concentration of air ions was detected. The ionization level is an original indicator of energetic saturation and aerosol pollution of atmospheric air.

Abstract: Creating precise climatic maps (temperature and precipitation map especially) on small areas such as drainage basins or landform units is always very useful for ecology of plants, distribution of vegetation and also different types of agricultural land. The geographic information system (GIS) analysis of several key-factors (aspect and slope of terrain, insolation degree, thermal gradient, geology and structure of landforms) offers the necessary tools to operate with in order to create an accurate climatic map. This method was applied in order to create a map showing the distribution of temperatures in the Olanesti drainage basin, a 235 km2 area located at middle latitude, in Romania. After creating the DEM, aspect and slope of the terrain, reclassifying categories and calculating the thermal gradient, a map showing the distribution of the annual mean teperature is obtained. Other climatic parameters could be calculated for small areas too, with precise results. These demonstrate that not only elevation and mathematical location of an area are important factors in the distribution of temperature, but als the aspect, the gradient, the insolation, the type of rock and the structure.

Abstract: The basin of Karinca river, in the north-west of Turkey, covers an area of 29, 840 ha. Pronounced changes in land use emerged as a result of the development of activities in the tourism sector in Turkey in the 1970 ' s. The basin has been significantly affected in the course of this process. This study was conducted in order to determine the land use changes (as well as the type of changes and their direction) occurring in the use of land in the Karinca river catchment for the period 1979-2007. The geographical data were gathered by using 1:25000 scale topographical maps as a basis. Thus, the existing soil and land use data from 1979 were processed on these bases and the main materials rendering the land use were produced. Geometric verification was made by putting the previously prepared bases onto landsat ETM+ and satellite images of 2007. In the final stage, results pertaining to the changes in land use were obtained by overlapping the two sets of data. All processes were done using the ArcGIS Desktop v9 x program. According to the data of the year 1979, the catchment are consisted of 43.4% forest, 26.5% grassland, 18.3% olive groves, 10.6% agriculture and 1.2% built-up lands. Comparing these coverage with the data of 2007, show a clear shift among residential areas, olive groves and forest terrain. It was found that the agricultural areas, particularly along the shoreline, were converted into resort houses and that the olive groves (the dominant land use) shifted from lower regions to its upper sectors. All these changes caused loss of natural habitats leading to degradation.

Abstract: The limit between low morphological units is quite difficult to be established due to the fact that the lithological, elevation and/or structure differences are hardly visible. Thus, the contact between piedmont and plain units is represented, in many cases, by areas where limits are hard to be drawn. In order to establish the way geographic information system (GIS) may contribute to the determination of the aforementioned limits, we used the situation of the limit between the Getic Piedmont and the Romanian plain and compared the obtained results to examples from other areas with different formation and evolution conditions. Presently, the Getic Piedmont undergoes and modelling process as valleys widen, torrential enlargementts laterally advance, and slope denudation develop, which make difficult to establish a clear southern limit. The fan texture of the valleys, their age, the flowing direction, as well as the differences of altitude, lithology, and structure disposal represent the main elements when establishing limits even in the case of GIS analysis. The drawing of thematic layers rendering elements such as hydrographic system, hypsometry, DEM on a traditional cartographic support, orthophotoplans, satellite images, for a better interpretation of the geomorphologic aspects allow a more objective attempt of reconstructing the morphological limits.

Abstract: The protection of our environment is a common task. All pollution that expose our soils, plants or in the narrower and wider sense environment will appear sooner or later in the food chain and in human beings who are at the top of the food-chain pyramid. The aim of our work is to give a brief overview about the effects of some industrial wastes on the physicological parameters of plants. Compost, black soot, sewage sludge and lime sludge dust was examined. Sunflower seeds were used in the experiments. The filtrates of examined materials were added to the nutrient solution in different quantities because of different solubility. The contents of sample elements and uptake of the element were measured by ICP, the relative chlorophyll contents by SPAD 502. Disadvantageous and advantageous physiological effects of compost, black soot, sewage sludge and lime sludge were proved. Larger concentrations of aluminium were measured in the roots than in the shoots. The concentrations of chrome were below the control value in the shoots when black soot, compost, lime sludge and sewage sludge were added to the nutrient solution. The concentrations of zince, phosphorous, magnesium and copepr were very low when black soot was used, and it was lower than the control. The dry matter of shoots increased when compost and sewage sludge was used, but the growth of roots remained under the control level.

Abstract: In irrigated agriculture, irrigation water volume and duration of irrigation can be optimized utilizing soil water dynamics data. Val Venosta in South Tyrol (Northern Italy) is a region where irrigation represents a central factor of production in the Tyrolese fruit-growing areas. Intensive orchard production is practised within an area of about 18,000 ha. Although fruit cultivation experts believe that intensive fruit cultivation should be based on regular irrigaiton of the fruit trees to guarantee optimum results in both fruit quantity and quality; however, fruit growers in the region follow very subjective criteria in regard to irrigation. At many locations much more water is used than the fruit trees actually need. Therefore irrigation in this region is a very cost-intensive factor of prodution and is criticized by the public for both economic and ecological reasons. To optimize the irrigation practice in this region it is essential to provide an objective basis for the irrigation process. A system of "precision irrigation" proposed, which is therefore based on objective and quantitative criteria focusing primarily on soil properties and hydrologica balance. This contribution will provide an overview of the current situation of irrigation and present results from soil-physical and soil-hydrological studies performed in this region since 2003.

Abstract: Features of gully morphometry and associated relief characteristics emphasize that gully develop under a wide variety of rock conditions, rainfall regimes, geomorphic predisposition, and human influence. Consequently many slopes within piedmont areas, in this case, the Getic Piedmont, are characterized by dense gully systems, as there occur excessive clearing, inappropriate land use, compaction of the soil caused by grazing, on the general background of a favourable climate. Both rainfall and runoff factors must be considered in assessing a water erosion problem. The erosional slope development within the Getic Piedmont was evaluated based on maps and field studies in the last 15 years, which emphasized that about 20% of the total surface of the piedmont is affected by gully erosion. The results show that the factors leading to the strong gully erosion in this area include-the widely distributed fraible rocks, the unique geomorphologic configuration, the strong and time-concentrated rainfall, the alternance of drought-humid periods that prepares the ground for the development of fissures in soils, the drought that influence the growth and recovery of vegetation, and the intense human activities. Gully erosion is one of the most visible forms of soil erosion, which affects its productivity, provides considerable material transport-torrential transports, debris flow, restricts land use, and threatens local communities.

Abstract: In the diverse relief of north-east part of Kosova a relatively wide range occupies the relief modelled by the descent phenomenon, which is conditioned by morph-structural and climatic factors quite suitable for their development. The morphogenesis activity of descent phenomenon is conditioned by the types of rocks, tectonic process of this region and climatic conditions. These factors condition horizontal and vertical relief fragmentation, slope, especially in Gollaku mountains and in SE part of Kopaonik mountain. Along the tectonic descents, the steepness is detaching and the detaching lines consisting of magmatic rocks show overthrows, demolitions and stony torrents, but the Teri gene composition formations are modelled by sliding and muddy torrents, depending upon the presence of clayey and alverolite belts on these Teri gene ones. The impact of factors and conditions on the relief of this part, the phenomena like demolition, overthrows, sliding, muddy torrents, stony torrents, etc., operate here, which play an important morphological role in the modelling of relief.

Abstract: The geographic pattern of soils in mountainous region of Georgia is presented. Time is considered as one of the most important factors of soil formation in mountain areas. The age of soil cover in the areas above 1000-1200 m a.s.l. is less than 10,000-12,000 yr b.p. These soils are considered as young component of landscape. In the landscapes below this level soils do not correspond to modern ecological conditions. We can confirm that in Georgia higher than 1000-1200m asl soils correspond to ecological conditions and they are mirror of landscapes, as one of the most important postulates of soil science. In other case, we can talk about soils memory-distorted mirror of landscapes. For diagnosing of relic features (pedogenic and lithogenic) in soils of Georgia the micromorphological method is used. The majority of landscapes in Georgia are heavily used for agriculture and suffer from high instability. These landscaps are very fragile today, characterized by high soil erosion and strong pollution with heavy metals and radionuclides.
