SCIENTIFIC RESEARCH AND ESSAYS

Morphological and palynological features were examined in the closely related Turkish endemic taxa Asperula serotina and A. purpurea subsp. apiculata. Their morphological features showed very minor difference such as internodes length and the vein thickness of leaf, however, the seed and pollen characteristics clearly appear to have taxonomic value. The clavate-reticulate seed surface suture of A. serotina clearly differs from that lineate-sulcate of A. purpurea subsp. apiculata. Similarly, the pollen perforations and number of spines differ in each taxon. Moreover, the two taxa are geographically isolated from each other. Ecological features are also briefly discussed. The seed and pollen micromorphological properties could be used for intra/interspecific classification of Asperula which is taxonomically critical

ANNALES BOTANICI FENNICI

Aspen, la pseudochlorantha Ehrend. and Asperula antalyensis Ehrend. from Turkey were described in 1958. General characteristics, seed structure and micromorphology, pollen measurements and other pollen characteristics were examined to determine the taxonomic status of these taxa. Morphologically, the two taxa cannot be easily distinguished, and the seeds and pollen grains are similar. The chromosome number is 2n = 22 for both taxa. Based on morphological, palynological and cytological similarities, and the fact that both taxa are found in the same habitats, we propose that A. antalyensis should be recognized as A. pseudochlorantha Ehrend. var. antalyensis (Ehrend.)

JOURNAL OF ANIMAL AND PLANT SCIENCES

Consolida samia P.H.Davis (Ranunculaceae) is one of the Top 50 Plants of IUCN Species Survival Commission. C. samia, as a new record for the Flora of Turkey is described and illustrated from West Anatolia in this study. The specimens were collected from a gravel-like substrate with the largest pebbles in the Balikesir border of Manisa. The description of the species has also been expanded, following collection of specific plant materials. In this study, the detailed morphological characteristics and palynological properties were determined and compared with the closely related taxon C. hellespontica (Boiss.) Chater. Also, line drawing, photographs and a distribution map of C. samia species of Turkey were presented. Our studies led us to recommend it as CR Blab (iii,v)+2ab(iii,v), according to the 2001 IUCN categories

NORDIC JOURNAL OF BOTANY

Rosularia globulariifolia (Fenzl) A. Berger and R. pallidiflora (Holmboe) Meikle were originally described as species in Umbilicus DC. in 1842 and 1914, respectively. In the present study, morphological and palynological features were examined in detail to determine the status of these taxa. The general characteristics, seed structure and micromorphology, pollen measurements and pollen characteristics were established. Morphologically, the two taxa cannot easily be distinguished. Pollen grains of both species are tricolporate, subspheroidal and eutectate, ornamentation is psilate and exine structures are similar. Based on morphological and palynological similarities, and the fact that both taxa are found in the same habitats, we propose that R. pallidiflora should be reduced to the rank of variety as Rosularia globulariifolia (Fenzl) A. Berger var. pallidiflora (Meikle) Minareci & K. Yildiz comb. et stat. nov

ARCHIVES OF BIOLOGICAL SCIENCES

In this study, the proximate chemical composition, total flavonoid and a-tocopherol amounts and antioxidant activities of five endemic Asperula taxa (Rubiaceae) (A. brevifolia, A. pseudochlorantha var. antalyensis, A. pseudochlorantha var. pseudochlorantha, A. purpurea subsp. apiculata and A. serotina) were determined. Antioxidant properties of methanol extracts were studied by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. Among the all Asperula extracts A. brevifolia showed the most potent radical scavenging activities

The study of surface water quality in Buyuk Menderes River (Turkey): Determination of anionic detergent, phosphate, boron and some heavy metal contents

The Buyuk Menderes basin is very wide and the people living here deal with farming, which increases the importance of the river to the region. The pollution of the river increases because the industry, urbanization and agricultural activities are very intense in the river basin. For this reason, the aim of this study is to map the extent of pollution of Buyuk Menderes River, to detect sources causing pollution in the river and also to suggest solutions for taking necessary precautions. Anionic detergent, phosphate, boron and heavy metal concentrations were determined in water samples taken from Buyuk Menderes River in this study. Mean concentrations of anionic detergent, phosphate, boron, copper, chrome, nickel and lead were found 0.2345 mg l-1, 0.0181 mg l-1, 0.8352 mg l-1, 0.0035 mg l-1, 0.0045 mg l-1, 0.0247 mg l-1, 0.0002 mg l-1, respectively. © 2018, ALÖKI Kft., Budapest, Hungary

CYTOLOGIA

Karyology of the 6 Silene species from Turkey was investigated. Diploid chromosome numbers and the basic chromosome number of the studied taxa were obtained as 2n=24 and x=12 respectively. The karyotype analysis of S. viscosa, S. eremitica, S. skorpilii and S. confertiftora were carried out for the first time. Also the chromosome numbers of S. eremitica and S. confertiflora were determined for the first time. The largest chromosomes were observed in S. otites and the smallest ones were observed in S. viscosa. S. otites shows the highest A(1) index. S. skorpilii represents the highest interchromosomal asymmetry coefficient (A(2)). The karyologic results oh the study and the analysis of chromosomal morphology of each taxon were shown as tables

INDIAN JOURNAL OF GENETICS AND PLANT BREEDING

Karyotype studies were performed in five taxas of Asperula viz., Asperula brevifolia, A. pseudochlorantha var. pseudochlorantha, A. pseudochlorantha var. antalyensis, A. serotina and A. purpurea subsp. apiculata from the section Thlipthisa, and their diploid (2n), and the basic (x) chromosome numbers were determined as 2n=22 and x=11, respectively. Chromosome length varied from 0.80 gm (A. serotina) to 2.40 mu m (A. brevifolia). Chromosomes are principally metacentric except for A serotina, which has submetacentric chromosomes. A. serotina showed the highest intrachromosomal assymetry coefficient (A(1)) index and A. pseudochlorantha var. antalyensis represented the highest interchromosomal asymmetry coefficient (A(2)). The chromosome numbers of A. brevifolia, A. serotina and A. purpurea subsp. apiculata were reported for the first time

Determination Of Heavy Metals In Fish, Water And Sediments Of Avsar Dam Lake In Turkey

In the present study, some heavy metals (Cd, Cr, Cu, Fe, Ni and Pb) were seasonally determined in water, sediment and some tissues of Cyprinus carpio from Avsar Dam Lake, which is an important water source for irrigation and drinking in Turkey. Heavy metal levels in water, sediment and fish samples were analyzed by inductively coupled plasma spectroscopy (ICP/AES). The obtained results showed that the average values of Fe in water samples were higher than the respective reference values for fresh water. Results for levels in water were compared with national and international water quality guidelines, as well as literature data reported for the lakes. The analysis of heavy metals in sediments indicated that among the six heavy metals tested, Fe was maximally accumulated, followed by Ni, Cu, Cr, Pb and Cd. Heavy metal concentrations were found to decrease in sequence of the Cyprinus carpio samples, in the muscle and stomach-intestine as Fe > Cu > Pb> Ni > Cr > Cd; in the gill, heart and liver as Fe > Cu > Ni > Pb > Cr > Cd and in the air sac as Fe > Cu > Ni > Pb > Cd >Cr. In the fish samples, cadmium, chromium, nickel and lead concentrations exceeded the tolerable values provided by international institutions
