Turkish Journal of Agriculture and Forestry

Developing forest management plans for sustaining the full range of forest values is a challenging task. One of the difficulties in this process is to set and achieve management objectives, and conservation targets. A sustainable forest management concept requires that a target forest structure (the composition and the configuration) be set before developing alternative management actions for the achievement of management objectives and the conservation targets. In this respect, developing and understanding vegetation succession play important roles in setting the target forest conditions. This study was conducted in the Bulanıkdere Forest planning unit (Kırklareli, Turkey) where the biodiversity-integrated multiple-use forest …

Quantifying Granivory In A Reconstructed Prairie: Affects Of Season, Species, Seed Predators, Sacrificial Food, And The Chemical Deterrent Capsaicin, Craig M. Hemsath Jan 2007

Quantifying Granivory In A Reconstructed Prairie: Affects Of Season, Species, Seed Predators, Sacrificial Food, And The Chemical Deterrent Capsaicin, Craig M. Hemsath

Dissertations and Theses @ UNI

Floral diversity of reconstructed prairies is often low compared to remnant prairies. Studies have demonstrated it is feasible to increase forb diversity in these prairies through overseeding and mowing, but overall rates of seedling establishment range from 0.1% to 1% of sown pure live seed. One explanation may be the ubiquitous populations of granivorous animals eating much of the seed . In this thesis I measured the amount of granivory occurring in a reconstructed prairie. I also tested how season, seed species, seed predator, sacrificial food, and chemical deterrents affect granivory in the reconstructed prairie. I hypothesized that granivores remove …

Turkish Journal of Veterinary & Animal Sciences

The acute toxicity of carbaryl, methiocarb and carbosulfan to juvenile rainbow trout (Oncorhynchus mykiss; 1.92 ± 0.5 g) and guppies (Poecilia reticulata; 0.45 ± 0.04 g) was evaluated in 96-h toxicity tests under static conditions. Concentrations in the toxicity test ranged from 0.85 to 8.5 mg/l for carbaryl, from 0.7 to 28.0 mg/l for methiocarb, and from 0.031 to 12.5 mg/l for carbosulfan. Carbaryl and methiocarb were more toxic to rainbow trout than to guppies. However, compared with rainbow trout, guppies were more sensitive to carbosulfan. The incidence of mortality in fish increased significantly (P < 0.05) with increasing pesticide concentrations. The time required to kill 50% (LT_{50}) of the rainbow trout at the lowest concentrations of carbaryl, methiocarb, and carbosulfan was 51 h 12 min, 74 h 35 min, and 107 h 57 min, respectively. As insecticide concentrations were increased, LT_{50} values decreased (P < 0.05).

Investigation Of Some Biochemical Parameters And The Antioxidant System In Calves With Dermatophytosis, Mahmut Karapehli̇van, Erdoğan Uzlu, Necati̇ Kaya, Orhan Kankavi̇, Kerem Ural, Mehmet Çi̇ti̇l

Turkish Journal of Veterinary & Animal Sciences

The study included 10 clinically healthy calves (group 1) and 10 clinical cases of dermatophytosis (group 2). The influence of dermatophytosis on some serum biochemical profiles and the antioxidant system was investigated. Serum malondialdehyde (MDA), reduced glutathione (GSH), uric acid, nitric oxide (NO), total sialic acid (TSA), lipid-bound sialic acid (LBSA), total protein (TP), and albumin levels were measured in groups 1 and 2. Calves in group 2 had significantly higher (P < 0.001) MDA, NO, TSA, and LBSA levels, and a higher P < 0.01 TSA:TP ratio; however, GSH and uric acid levels were significantly lower (P < 0.001). There was no significant difference between the groups in total protein and albumin. These findings suggest a relationship between dermatophytosis, the antioxidant system, and lipid oxidation.

The aim of this study was to investigate the differences in spermatological and seminal plasma biochemical characteristics between normozoospermic and oligoasthenozoospermic bulls. A total of 8 bulls were used and they were divided into 4 groups: Holstein normozoospermic (HN) and oligoasthenozoospermic (HO), and Brown Swiss normozoospermic (BSN) and oligoasthenozoospermic (BSO). Spermatological parameters investigated included semen volume, color, concentration, motility, and percentage of abnormal sperm. Biochemical parameters measured in seminal plasma included pH, glucose, urea, creatinine, uric acid, cholesterol (CH), triglyceride, Mg, inorganic P (P_i), Ca, Na, K, and Cl ion concentrations. Colorimetric and ion selective electrode methods were used for …
