Forests, a valuable source provided by nature to living beings, are indispensable for many living organisms; hence, it is important to ensure the sustainability of forests. Determining the factors that exposure threats to the forests, executing protective methods against them and putting these methods into practise are important for the ecological cycle. Bark beetles, which have destructive effects on the ecosystem, are one of the factors that expose a threat to forests. Therefore, monitoring of these species and determination of effective control strategies are increasingly gaining importance in forestry. Conventional pheromone traps, which are being currently used, provide limited information on flight times of target species. Therefore, the technological development of the capture systems of these traps will determine future control trends. Hence, pheromone traps with electronic control unit were prepared in earlier (ѵ1) and new designed (ѵ2) versions. In ѵ2, 97.5% of target species were counted, and instant temperature, humidity and time parameters at the time of capture were recorded at a practiced field work for the system. In addition to the instant parameters recorded in ѵ2, an anemometer used for measuring wind speed, which is considered to have influence on the behaviour of target species, was incorporated into the system. In the trials, the counting success rates under daylight and darkness conditions for Ips sexdentatus adults were 98.1 and 97%, whereas the counting success rates for Pityocteines curvidens adults, which are smaller in size, were 96 and 99%, respectively. In conclusion, data obtained by recording the amount of target species along with the capture moment and parameters related to this will be very useful and provide determinative in the management of target species.
Article; biodiversity and ecosystems a new approach to determine the capture conditions of bark beetles in pheromone-baited traps

Forests form an organic unity with a great number of organic and inorganic components and tend to maintain the sustainability of their existing balance. However, some factors which adversely affect the balance of nature may interrupt this sustainability. The epidemic which is formed by bark beetles in their spreading region, due to various factors, changes the stability so much that interference is required. One of the most common methods used to monitor these beetles is pheromone-baited traps. The recognition of parameters, such as date (day/month/year), temperature and humidity, when bark beetles are captured in pheromone-baited traps, especially those used for monitoring will help to increase the trap efficiency on land and to develop an effective strategy for combating pests. In this study, an electronic control unit was added to pheromone-baited traps in order to obtain all of the above mentioned parameters. This unit operates with microcontrollers and data related to the parameters is saved in a storage unit. This is triggered by the beetle at the moment it is captured in the trap. A photovoltaic system was used to meet the energy needed for the system functioning and to complete the counting process in due time.
Rumen Ciliates from the Goitered Gazelle (Gazella subgutturosa) living in the Şanliurfa Province of Turkey

Rumen ciliate composition was surveyed in a single Goitered gazelle, Gazella subgutturosa (Güldenstaedt, 1780), living in the Şanliurfa Province in Turkey. As a result of the survey, 3 species belonging to the genus Entodinium, E. dubardi, E. nanellum and E. simplex, were detected. The ciliate density in the rumen content was 87.5 × 104 ml-1. This is the first report on rumen ciliates in gazelle living in Turkey and no previously unknown species were observed. In addition, this is the first report from a wild animal in Turkey. The Goitered gazelle has a fauna somewhat similar to that previously observed in Mongolian gazelle. © Biharean Biologist, Oradea, Romania, 2012.
