Demography and population structure of Northeastern mediterranean monk seal population

The Northeastern Mediterranean coasts that border southern Turkey host one of the last strongholds for the survival of the endangered Mediterranean monk seal (Monachus monachus, 1779). The seal colonies inhabiting south coast of Turkey have been studied since 1994 through various short-term research projects focusing on distinct small populations that were thought to be isolated. In this study, the entire extent of the area was monitored approximately for 3 years (between 2015 and 2018) with camera traps places in 20 caves known to be actively used by the seals. A total of 7014 images taken throughout the study period, along with 25,100 images taken previously, were used to identify the seals inhabiting the area.  In total, 37 individuals were identified based on the natural marks on the body. Based on photo-identified seals, a mark-recapture method was applied to estimate the total population size within the Northeastern Mediterranean. The overall population size was found to be 46 (SE=7.7) in the case of closed population and 53(SE=34.8) in the case of open population during the study period.  The range of identified seals was almost six times larger than previously documented in the same area, reaching distances up to 245 km. The population estimate indicated a decrease in population size compared to previous studies.  Finally, the study emphasises the importance of long-term monitoring studies elucidating changes in the demographic parameters in relation to threats posed, rather than cut-paste measurement suggestions which are not applicable in reality, while structuring the conservation actions targeting survival of this highly endangered species

Preliminary Assessment of the relationship between CPUEs and large-scale climate Indices on the South coast of Turkey

The Mediterranean, particularly the east side, is considered one of the most susceptible regions to climate change. The marine fauna, including fish, has already been reported to respond to changing conditions. It is fundamental to understand which changes in the fish stocks are related to varying temperatures to design sustainable fishing practices. On the Turkish coast of the Mediterranean Sea, fluctuations in the fish stocks are attributed primarily to overfishing, pollution, and the Lessepsian invasion. As the region is listed among the fastest-warming areas, enlightening the impact of rising temperature on fish populations is essential. Within this context, we hypothesized that the large-scale climate indices might explain the changes in the abundance of exploited fish populations on the south coast of Turkey. We aimed to measure the responsiveness of catch per unit effort (CPUE) to North Atlantic Oscillation Winter Index (NAO DJFM) and East Atlantic-West Russia (EA/WR) seasonal indices. For that purpose, official landing and fishing fleet statistics reported by the Turkish Statistical Institute (TUİK) compiled for 1987 and 2020. Landings of fish species are categorized regarding the fishing practice targeting them. The total number of fishing vessels is used to calculate the annual CPUEs of trawlers and purse seiners. To investigate the relationship between climate indices and variations in CPUEs, cross-correlation analysis incorporating the differencing and pre-whitening methods has been performed. In general, CPUE of trawlers was significantly affected by NAO DJFM and EA/WR indices, while CPUE of purse seiners was significantly correlated only with EA/WR Winter Index. Considering the role of the EA/WR pattern on precipitation and NAO teleconnection on temperatures, the large-scale climate indices seem to impact the reproductive success and growth of the fish populations. Our results indicated that the large-scale climate indices have great potential to explain particular patterns of CPUEs. However, other, drivers such as fisheries and eutrophication that are probably acting in combination with climate must be included in the future studies

THERMAL CONDUCTIVITY OF LAMINATED VENEER LUMBERS BONDED WITH VARIOUS ADHESIVES AND IMPREGNATED WITH VARIOUS CHEMICALS

Desmodur VTKA and Urea formaldehyde) on wooden materials (Scotch pine and oriental beech) cut tangentially and radially impregnated with Tanalith-C, creosote, and sodium silicate in layer (3, 4, 5) of laminated veneer lumber (LVLs) on thermal conductivity. The lowest thermal conductivity of 0.103 Kcal/mh°C was obtained in Scotch pine, cut tangentially, impregnated with creosote, bonded with urea formaldehyde, and 3 layer LVL. The highest thermal conductivity of 0.185 Kcal/mh°C was obtained in oriental beech, cut radially, impregnated with Tanalith-C, bonded with PVAc, and 5 layers LVL. Consequently, oriental beech wood cut radially and impregnated with Tanalith-C, bonded with PVAc adhesive and 5 layers in LVL can be used as a material in construction where the thermal conductivity is required. Scotch pine wood cut tangentially and impregnated with creosote, bonded with urea formaldehyde adhesive and 3 layers in LVL can be used as a material in construction where the insulation is required

THE EFFECT OF HARVESTING TIMES ON OIL AND FATTY ACID COMPOSITION OF PEANUT VARIETIES GROWN IN MAIN CROPPED CONDITION IN CUKUROVA REGION (MEDITERRANEAN AREA) IN TURKEY

This study was conducted at the experimental area of the Department of Field Crops, Faculty of Agriculture, Cukurova University as a main crop in 2015. The objective of this study was to determinate the effect of harvesting dates on oil and fatty acid composition of peanut (Arachis hypogaea L.) varieties grown in main cropped condition in Cukurova region. The experimental design was a split plot with three replications. The Halisbey, Sultan, Arioglu-2003, Osmaniye-2005, NC-7, Batem-5025, Flower 22, Flower-32, Flower-36, Brantley and Wilson peanut varieties (Virginia market type) were used as a plant material in this research. The plants were harvested at 149, 156, 163 and 170 days after sowing (DAS). Oil and fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, behenic acid and lignoceric acid) content and Oleic acid to Linoleic acid ratio (O/L) of peanut varieties were investigated. As a result, the oil percentage of peanut varieties was increased from 47.8% to 50.3% when the harvesting delayed from 149 DAS to 170 DAS. While the palmitic and linoleic acid percentage was decreasing, the stearic and oleic acid percentage was increased when the harvesting delayed from 149 DAS to 170 DAS in peanut varieties. The others fatty acids were not affected by the harvesting time

A Preliminary Study on Protease Activity of Russian Sturgeon, Acipencer gueldenstaedtii Brandt and Ratzenburg, 1833, at Early Life Stages

The fish feed industry continues to researches for optimum diet demands for candidate species culture. For this purpose, in vitro analyze methods may be more efficient than in vivo assays. This study includes two different stages; the first one is about the effect of commercial feeding protocol on protease enzyme alteration and the second one is about the inhibitory effects of different protein sources on early life proteases of Russian sturgeon, A. gueldenstaedtii, juveniles. In the first step, feeding with live prey and transition period to artificial feed significantly affected the daily amount of protease in digestive system ( P < 0.05). In the second part, some protein sources used in micro diets were tested in vitro for examination of their possible inhibitory effects on the proteases of Russian sturgeon larvae. The minimum inhibitory effect was obtained from fish meal (15.44%), but however, soybean protein concentration, soybean meal, corn gluten and rice bran inhibited the proteases significantly higher than FM and its combinations (63.55, 71.81, 72.24, and 80.77%, respectively). Additionally, dual combinations between fish meal and soybean meal/soybean protein concentration with the ration of three to one ( 3: 1) was moderate (26.38 and 22.13 %), whereas blood meal extremely produced a 97.28% inhibitory ratio

Effects of Fixed and Removable Functional Appliances on Skeletal and Dentoalveolar Structures

Aim:To compare the skeletal and dentoalveolar changes after Herbst and Twin-block treatment in Class II division 1 patients.Subjects and Methods:Cephalomet-ric radiographs of 20 patients treated with Herbst and Twin-block appliance and 10 untreated subjects are used. Totally 29 maxillary, mandibular, maxillomandibu-lar and dentoalveolar measurements were achieved. Paired sample t-test was used to determine intra-group differences and one way analysis was used to determine inter-group differences.Results:After Herbst appliance therapy, an increase in mandibular corpus length and mandibular incisor protrusion and decrease in ANB, overjet and overbite were observed. In Twin-block group, significant increases were observed in all mandibular measurements except nasion perpendicular to pogonion. A point moved anteriorly and effective middle face length increased. Increases were observed in effective mandibular length and in all measurements that show mandibular sagittal (Go-Gn) and vertical (Co-Go, S-Go) dimension. Only maxillary nasal plane to upper first molar length that shows maxillary molar eruption increased in dental measurements. Comparison of groups showed that both appliances decreased ANB angle and overjet. In Herbst group, significant differences were observed in effective middle face dimension and distance of Nasion perpendicular to A point, compared with the Control group. No significant difference was observed in other mandibular and dentoalveoler measurements between the groups.Conclusions:Twin-block appliance showed more skeletal changes and the Herbst appliance showed skeletal and dental changes in our study. The appliances exhibited similar effects compared with the Control group
