    Adana'daki iki koruma alanının memeli faunası: Akyatan yaban hayatı geliştirme sahası (Karataş) ve Halep çamlığı (Yumurtalık)
    (Niğde Üniversitesi / Fen Bilimleri Enstitüsü, 2016) Arslan, Mehmet; Karataş, Ahmet
    Bu çalışmada, Adana ilindeki iki koruma alanının (Akyatan ve Halep Çamlığı) memeli faunası araştırılmıştır. Araştırma sırasında hayvanların bir kısmı doğrudan gözlenmiş, bir kısmı ise ayak izi, dışkı, yuva takibi ve baykuş peletlerinin analizi gibi dolaylı yoldan tespit edilmiştir. Ayrıca 23 ayrı noktaya kurulan üç fotokapandan elde edilen görüntülerden yararlanılmıştır. Memeli türlerinden küçük boyutlu olanları tel ve canlı (Schermann) kapanlar kullanılarak yakalanmıştır. Yapılan çalışma sonucunda: Erinaceus concolor, Crocidura suaveolens, Lepus europaeus, Apodemus flavicollis, Mus macedonicus, Rattus rattus, Meriones tristrami, Hystrix indica, Canis aureus, Vulpes vulpes, Martes foina, Meles meles, Felis silvestris, Felis chaus, Herpestes ichneumon ve Sus scrofa olmak üzere 16 memeli türünün alanda doğal olarak yayılış gösterdiği belirlenmiştir. Sonuç olarak alanların memeli faunası güncellenmiş ve alan koruma statülerinin devam ettirilmesinin önemine değinilmiştir.

    Chemical and biological characteristics of propolis from Apis mellifera caucasica from the Ardahan and Erzurum provinces of Turkey: a comparative study
    (Inst Medical Research & Occupational Health, 2021) Arslan, Mehmet; Sevgiler, Yusuf; Guven, Celal; Murathan, Zehra Tugba; Erbil, Nurcan; Yildirim, Deniz; Buyukleyla, Mehmet
    The aim of this study was to compare the biological activities of ethanolic propolis extracts of Apis mellifera caucasica obtained from Ardahan and Erzurum provinces of Turkey. Samples were tested for antioxidant, anticytotoxic, anticarcinogenic, antibacterial, and antifungal potentials using different techniques. Propolis samples from the two provinces had different mineral and organic compositions related to their geographical origin. The ferric reducing antioxidant power (FRAP) test showed superiority of Ardahan propolis over the Erzurum. Regardless of origin and the presence of mitomycin C in the culture medium, propolis enhanced human peripheral lymphocyte viability, which depended on the duration and propolis concentration. Antiperoxidative activity on MCF-7 breast cancer cells was concentration-dependent. Erzurum propolis showed the highest anticarcinogenic activity at the concentrations of 62.5 mu g/mL and 125 mu g/mL, which dropped at higher concentrations. All propolis samples also showed antibacterial activity against the tested human pathogens similar to ampicillin and penicillin controls, except for Pseudomonas aeruginosa. However, they did not exert any antifungal activity against Candida albicans and Yarrowia lipolytica. In conclusion, propolis samples from both provinces showed promising biological activities, but further research should focus on finding the right concentrations for optimal effect and include the cell necrosis pathway to get a better idea of the anticarcinogenic effects.

    Comparison of organic and traditional production systems in chickpea (Cicer arietinum L.)
    (2013) Caliskan, Sevgi; Erdogan, Cahit; Arslan, Mehmet; Caliskan, Mehmet Emin
    Yield and yield components, and protein content of chickpea (Cicer arietinum L.) were compared in traditional and organic production systems since organic farming has many advantages on environment, animal and human health over traditional production systems. In the study, organic production system, green manure, farmyard manure and effective microorganisms and their combinations were tested as six treatments. Seed yield and some yield components were found higher in the traditional production system than those of organic production systems. The highest protein content was obtained in green manure and farmyard manure applications. Among the organic production systems, green manure and farmyard manure applications could be strongly recommended for organic chickpea producer since the highest seed yields with 2729 in 2007 and 3838 kg ha -1 in 2008 were found in green manure + farmyard manure treatment among the organic production systems.
