The study aimed to evaluate the effects of L-carnitine on honey bee (Apis mellifera) drone spermatozoon at post-thaw. Semen samples obtained from sexually mature drones were pooled. Then, pooled semen was diluted with different concentrations of L-carnitine (2.5 mM/5 mM/10 mM) and without L-carnitine (control) supplemented extenders. Motility, plasma membrane functional integrity, acrosomal integrity and mitochondrial function were negatively affected by the cryopreservation process but DNA integrity was not affected. Malondialdehyde (MDA) concentration was used for analyzing the membrane lipid peroxidation status and a better result was obtained in the LC5 group compared with the control group at post-thaw. L-carnitine groups had a positive effect on sperm motility, plasma membrane integrity, and mitochondrial function compared to the control group (P<0.05). Acrosomal integrity was better preserved in the LC5 group compared to the control group. The study shows that LC supplemented extenders have beneficial effects on honey bee drone sperm parameters. The results of the present study demonstrated the beneficial effect of using a 5 mMol LC supplemented extender.

Ecology-based tourism, which is integrated with nature, developed in environmentally conscious areas and enriched by different cultures, has become more important in the direction of extending tourism throughout the year. While the landscape values of the area are important functions for tourism activities to be carried out in natural characteristics, the preferences of the users are also important. Ecology-based tourism, which develops in connection with the concepts of intacteness, the protection-use balance and sustainability, and the demands and expectations of tourists, constitute the basis of our study. For this purpose, the study was carried out in Kumyaka, a small coastal neighborhood (village) of the county of Mudanya in the province Bursa, Turkey with important natural, historical and cultural assets. Fieldwork, field analysis, literature search, interviews with tourists coming to the field, interviews with the day trippers and survey work were conducted in the study. While evaluating the ecology-based tourism potential of the area, the demands and expectations of tourists have been taken into account together with the available area data. According to the results of the survey, tourists are mostly interested in having the most scenic value and quietness when choosing the area. The types of tourism that tourists most wanted to experience in the field were 42.38% culture tourism and 32.32% nature tourism. As a result of tourists' demands and expectations, the tourism activities to be carried out in accordance with the possibilities of the area were examined and ecology based planning proposals and holistic planning approaches were developed.
