In Turkey, population increase rate is rather high. Because of this, natural and cultural resources are used there is an intensive pressure on the since they for the recreation and tourism requirements besides the basic requirements. Nowadays, for supplying the sustainability in recreation and tourism issues, alternative tourism types were developed in the rational land use planning concept. Especially in Turkey, an alternative tourism type, the plateau tourism gained importance due to the traditional structure. Bartın City has four potential areas where plateau tourism could be practiced. The natural and cultural resources for the recreation-tourism usage of the Ardıç, Gezen, Uluyayla and Zoni Plateaus which were considered for this study were determined by local observations and by using Rapid Rural Evaluation Technique. By SWOT analysis, the strong aspects and opportunities contributing to the realization of the recreational activities, weak aspects and threats weakening the realization of these activities were determined and evaluated. As a result of these evaluations, camping-camp with tent, climatism, mountain bike riding, caving (for Uluyayla), golf (for Uluyayla), horse riding, mountaineering, trekking, skiing, bird watching and jogging in nature activities were determined as the most appropriate activities for these areas.

In this study; the effects of extrusion conditions on solubility (WSI) and water absorbtion (WAI) properties of tarhana produced with different wheat flours were evaluated. With this purpose of comparing properties of traditional and extruded tarhana; tarhana samples prepared with different wheat flours (white wheat flour, pregelatinized wheat flour and whole wheat flour) were extruded at different barrel temperatures (120, 140 and 160 0C) and screw speeds (80, 120 and 160 rpm) by using a twin screw extruder. At the end of the study; it was determined that values of WSI and WAI of extruded tarhana samples were higher than that of traditional tarhana samples. Additional, in both tarhana production techniques; usage of pregelatinized wheat flour were increased WAI and WSI values significantly. The barrel temperature, screw speed and type of wheat flours have important effects on the properties of extruded tarhana. It was observed that while flour type, interactions of barrel temperature X flour type and screw speed X flour type had important effects on WAI, both individual parameters and interactions of barrel temperature X flour type and screw speed X flour type had important effects on WSI during extrusion. As a result, usage of pregelatinized flour by extrusion technique in tarhana production should be suitable for instant soup production.

Determining of high yielding and good quality genotypes for increasing durum wheat production is necessary in different regions. The aims of this study were to determine new durum wheat genotypes with high yielding and quality properties suitable for the Tokat region and make a contribution to increase durum wheat production. This research was conducted in 2001-2002 and 2002-2003 growing seasons at the Kazova plain in Tokat. As plant materials, 23 lines and Cham 1, Altar 84 and Waha international cultivars obtained from ICARDA along with Sofu and Gediz-75 as national cultivars were used in the trial. The experiments were conducted in the randomized complete block design with three replications. There were significant differences among genotypes for all characters. According to the results, Mrb3/Albit-1 for grain yield, Terbol97-1 for percentages of yellowberry kernels, Lagamarb-1 for not only grain yield but also quality were recommended for Tokat-Kazova region. Durum wheat production in the region could be increased by using new genotypes which are determined in this and similar studies.

Key Words: durum wheat, genotype, yield, yellowberry kernel percentage

In this study, a total of 17 Cladoceran and Copepod species were identified in Kesikköprü Dam Lake (Ankara) between April 1995 and May 1996. The average individual number of copepod species was found to be 51279 Ind/m3. The highest number of copepod species was recorded in May 1995 and the lowest in February 1996. Arctodiaptomus acutilobatus was the most abundant copepod species with an average of 18541 Ind/m3. The average individual number of Cladoceran species was found to be 47282 Ind/m3. Daphnia longispina was found as the most abundant cladoceran species and its peak was observed in April 1995. The highest number of Cladoceran species was recorded in June 1995 and the lowest in January 1996.
