Karlıoǧlu Kılıç, Nurgül; Paksoy, Mehmet Yavuz; Özdemir, Emrah
The pollen morphology of three species of the genus Chrysophthalmum Schultz Bip. (Asteraceae) found in Turkey were studied with light microscope (LM) and scanning electron microscope (SEM). The three species were C. dichotomum Boiss. & Heldr., C. gueneri Aytac & Anderb., and C. montanum (DC.) Boiss. Pollen grains of the Chrysophthalmum species were identified as spheroidal and their apertures were shown to be tricolporate. The polar and equatorial axes, distance between colpus apices, length/width of colpus, length/width of porus, exine thickness, and length/base of spine were measured on the pollen grains. Pollen ornamentation of the three species was identified as echinate in LM and echinate-microperforate in SEM. These studied species were distinguished from each other using Kruskal–Wallis and Dunn’s test. The results indicate that pollen characteristics could be useful for distinguishing the examined species.

Dirmenci, Tuncay; Özcan, Taner; Açar, Mikail; Arabacı, Turan; Yazıcı, Türker; Martin, Esra
Origanum munzurense Kit Tan & Sorger (Sect. Brevifilamentum Ietsw.) was described by Kit Tan & Sorger in 1984, and it is an accepted species related to O. acutidens (Hand.-Mazz.) Ietsw. belonging to sect. Brevifilamentum. It is morphologically intermediate between O. acutidens and O. vulgare L. subsp. gracile (K.Koch) Ietsw., and its type locality lies in the overlap zone between the geographic distributions of these two taxa. We hypothesized that O. munzurense is in fact a hybrid between the two aforementioned taxa and we tested this hypothesis with the general morphology, chromosome features, and nuclear (ITS1–ITS2) and chloroplast (rpl32) DNA sequences of specimens of O. munzurense and its putative parental species, O. vulgare subsp. gracile and O. acutidens. The somatic chromosome number of O. munzurense, O. vulgare subsp. gracile and O. acutidens were counted as 2n = 30. Origanum munzurense presented polymorphic sites in the nuclear ITS region, but the chloroplast markers did not allow us to identify the putative maternal of O. munzurense. Our results suggest that O. munzurense is indeed a hybrid, and its rearrangement as a new homoploid hybrid (O. ×munzurense) would be more accurate. These present results support previous reports for the speciation of Origanum members via hybridization.

Işık, Erdem; İnallı, Mustafa; Celik, Erkan
Energy analysis plays a vital role in developing an optimum and cost-effective design for the heating, ventilating and air conditioning system of a building. The values of heating degree days (HDD) and cooling degree days (CDD) are used to analyze the demand for energy for buildings. In this study, the HDD and CDD values for Turkey were calculated using estimated temperature values. An artificial neural network (ANN) and an adaptive network-based fuzzy inference system (ANFIS) were applied for the estimation of temperature values. The Levenberg–Marquardt training algorithm was used for the feedforward backpropagation of the ANN, whereas the Sugeno-type fuzzy inference system was used for the ANFIS. Meteorological data from the last 11 years were used for the proposed approaches, and these were applied to different stations (n = 50) of the Turkish State Meteorological Service. In relation to the insulated building design, base temperatures have been considered as 16 °C and 18 °C for the HDD and 22 °C and 24 °C for the CDD based on a literature review. Two novel maps were prepared for the CDD and HDD. The calculated degree days and the maps are consistent with those from the Turkish State Meteorological Service.

In this study, the vegetation of epiphytic bryophytes in the Kamilet Valley and its surroundings (Arhavi, Artvin) was investigated. The study area is located within the borders of the Eastern Black Sea Mountains and is one of the 122 important plant areas in Turkey. The investigation of epiphytic bryophyte communities was carried out in 2016 during different vegetation periods according to Braun-Blanquet’s phytosociological methodology. Phytosociological data obtained from 65 relevés were ordinated using detrended correspondence analysis (DECORANA) and classified using two-way indicator species analysis (TWINSPAN). Consequently, six epiphytic bryophyte communities new to Turkey were determined with TWINSPAN and DECORANA: Leucobryo-Tetraphidetum pellucidae, Anomodonto attenuati-Neckeretum crispae, Frullanio tamarisci-Exsertothecetum crispae, Ulotetum crispae, Anomodonto attenuati-Neckeretum crispae-leucodontetosum sciuroidis, and Ulotetum crispae-isothecietosum alopecuroidis. All syntaxa are presented by analyzing them in terms of their ecological and floristic classifications.

Topal, M.; Arslan Topal, E.I.
In this study, the concentrations of Zn and Cr in downstream waters from Uzunçayir Dam (Tunceli, Turkey) were monitored during spring (March, April, May) and summer (June, July, August) season. Zinc and Cr concentrations in surface water samples were detected using the ICP-MS device. According to the data obtained the lowest Zn and Cr concentrations in the spring season were 65.43±3.2 μg/L in March at 10th day for Zn and 0.28±0.02 μg/L in March at 10th and 20th day for Cr, the highest Zn and Cr concentrations were determined to be 83.12±4.1 μg/L in May at day 30 for Zn and 0.48±0.02 μg/L in May at day 30 for Cr. The lowest Zn and Cr concentrations in summer season were 55.48±2.7 μg/L at 30th day in August for Zn and 0.54±0.03 μg/L at 10th day in June for Cr. The highest Zn and Cr concentration in summer season were found as 69.48±3.5 μg/L in June at day 10 for Zn and 1.23±0.06 μg/L in August at day 30 for Cr. The Zn and Cr concentrations in the downstream of Uzunçayir Dam were found to be smaller than the Zn and Cr concentrations given by the Surface Water Quality Regulation (SWQR). As a result, it was determined that there was no harm in using water from the Uzunçayir Dam as irrigation water or drinking water in terms of Zn and Cr concentrations.

This study identified not only the wild plants collected for food purposes by local people of Karaisalı County in the Mediterranean Region, but also the uses and local names of these plants. Field study was carried out over a period of approximately 2 years (2008–2010). During this period, 76 vascular plant specimens were collected. Demographic characteristics of participants, vernacular plant names, edible parts and utilization methods of the plants were investigated and recorded. In the scope of the study, the plant species were collected; herbarium materials were prepared; and the specimens were entitled. In addition, the use-value of the species was determined and was calculated for the food plants included in the study. A total of 76 food plants belonging to 30 families were identified in the region. The most common families are: Asteraceae (12 plants), Lamiaceae (10 plants), Rosaceae (9 plants), Polygonaceae (5 plants), Apiaceae (4 plants). The study showed that the plants used are either eaten raw or ripe, cooked as vegetable dish, consumed as jam, consumed as coffee, as spice, frying in oil or baked to be served as dishes such as stew, pie made by roasting the leaves, prepared sour souce is added to food. During this ethnobotanical research, it was verified that wild edible plants play an important role in diet in Karaisalı. We examined whether the plants used had literature records or not. Varied usages of a number of plants have been recorded for the first time by us. Tree of those plant are endemic. The plant flora of Karaisalı is threatened by such factors as grazing, expansion of new agricultural lands, and unsustainable picking of plants to generate income. Steps should be taken immediately to ensure the inclusion of relevant flora within conservation designations.

Işık, Erdem; Inallı, Mustafa
Limited energy resources and increasing need for energy due to population growth seem to lead researchers to focus on these issues. Forecast of meteorological data has significant importance in design of thermal systems. In this study, forecasting of meteorological data used in thermal system design was performed for fifty cities to represent the entire Turkey. Data obtained from General Directorate of Meteorology (MGM) were modelled by artificial neural networks and adaptive-network based fuzzy inference systems. Matlab software was used for modeling and forecasting of prospective data with high sensitivity in thermal systems. Surfer and ArcGIS software were used to create humidity, temperature, solar radiation maps for Turkey. Root mean square error (RMSE), mean absolute error and (MAE), coefficient of variation (COV) and the coefficient of determination (R2) were used to validate the result of the proposed approaches. The results were satisfactory with respect to RMSE, MAE, COV and R2 to forecast the meteorological data. Annual solar power potential maps for Turkey were also proposed and compared with MGM results. The results of the proposed approaches are compatible with the result of the MGM. The Turkey policy maker(s) from MGM can easily use these approaches if a software is constructed.

Çimen, Okay; Önal, Ayten Öztüfekçi
The İzmir-Ankara-Erzincan-Sevan-Akera Suture Belt (IAESASB) stretches from the Aegean Sea to the Lesser Caucasus and includes the remnants of the Northern Neotethys. The Ovacık and Pülümür Ophiolite Zone (OPOZ) to the north of Tunceli is less-known members of this belt. In this study, preliminary geochemical data from the basaltic and gabbroic rocks from this zone are presented to provide the first insights into their geochemistry. The studied mafic samples exhibit geochemical characteristics of an intra-oceanic subduction system. Three types of samples were differentiated on the basis of their major, trace and rare earth element (REE) geochemistry. The first one is boninitic and displays highly depleted elemental pattern (relative to N-MORB) and concave REE profile. The second type is akin to back-arc basin basalts (BABB) and generally reflects normal-MORB (NMORB)-like high field strength element (HFSE) patterns coupled with negative Nb anomalies. The last type is relatively similar to the BABB-type, but it lacks the marked negative anomaly in Nb and can be ascribed to the mid-ocean ridge basalt (MORB). The overall geochemical features suggest that these mafic rocks were predominantly generated in a supra-subduction setting from a subduction-modified mantle source. It is further suggested that the Ovacık and Pülümür Ophiolite Zone was formed in an oceanic arc-basin system within the northward subducting Northern Neotethys.

We studied the presence of possible Aphanomyces astaci infections in eight Turkish narrow-clawed crayfish (Astacus leptodactylus) populations by analyzing the prevalence and genotypes of the disease agent A. astaci. The qPCR analyses revealed A. astaci infection in seven of the studied eight populations, with the agent level A2 or higher. The agent levels among the infected populations varied from A0 to A5, i.e., from negative to high level of infection, based on qPCR ranking. Based on the sequencing of the chitinase gene and the mitochondrial ribosomal rnnS and rnnL subunits, we detected both A (As) and B (PsI) haplogroups of A. astaci in our samples, with each of the studied populations being carriers of only one haplotype. The results confirm previous detections of A. astaci in Turkish narrow-clawed crayfish populations and reveal, that both A and B haplogroup A. astaci carriers exist widely in A. leptodactylus populations of Turkey.

The micromorphological and anatomical characteristics of three species of Chrysochamela genus have been comparatively presented by using light microscopy (LM) and scanning electron microscopy (SEM). The micromorphological studies are related to the epidermal and seed surface. In anatomical studies, cross sections of the stems and leaves were examined and biometric measurement of cell and tissues were made. The stem and leaf anatomy of the genus were described. In addition, the stomatal index rate and stomatal index of these species were calculated. The leaf is dorsiventral in mesophyll-type. Except its C. noeana taxon, stellate trichomas are coincided in other taxon. Stoma can be observed on both sides of the leaf. Whereas stoma index rates of this genus were found in the range of 0.7 - 1.2, stoma types were observed as aniocytic and anomocytic. Seed surface of the genus can be found in reticulate, verrucae or in verrucaerugose types. In conclusion, the presence/absence of trichome over stem and leaves, the presence/absence of collenchyma in middle the vascular region, the seed shape, epidermal cell shape, and the characteristics of anticlinal boundaries and periclinal cell walls were found to be the important characters for identification of the Chrysochamela genus.

The environmental factors that affect the seasonal change of the phytoplankton community and composition in Karkamis Dam Lake were investigated on samples taken from five stations between January 2015 and December 2015. It was found that the phytoplankton of Karkamis Dam Lake consisted of 85 taxa belonging to Bacillariophyta (56 taxa), Chlorophyta (15 taxa), Chrysophyta (1 taxon), Cyanophyta (10 taxa), Dinophyta (2 taxa) and Euglenophyta (1 taxon). Members of Bacillariophyta and Chrysophyta increased well during spring, summer and also at the end of fall whilst Chlorophyta grew well only in summer and fall. Cyanophyta became dominant at the end of spring and in summer. However Dinophyta was remarkably conspicuous in winter as well as in spring and fall in terms of prevalence. Excessive reproduction of Cyanobacteria, which is a characteristic aspect of mesotrophic lakes, was observed in Karkamis Dam Lake in both May and July. Results of physical and chemical measurements and analysis indicated that the lake was mesotrophic based on PCA and Carlson trophic state index. Phytoplankton composition was found to be affected by environmental factors such as temperature, pH, dissolved oxygen, phosphate and nitrate through the year. Using these data, a strong model was developed for sustainable management in Karkamis Dam Lake.
