A new check-list of the mosses of Turkey

Abstract The check-list includes a list of genera, species, subspecies and varieties of Turkish mosses. It is composed of 726 species, subspecies and varieties representing 164 genera and 42 families. Accompanying the lists are a systematic arrangement of the genera, species and varieties and lists of synonyms, excluded species and of annotations. Three mosses, Pseudoleskeella rupestris (Berggr.) Hedenäs & L. Söderstr., Isothecium myosuroides Brid. var. brachythecioides (Dixon) C.E.O. Jensen, Eurhynchium hians (Hedw.) Sande. Lac. var. rigidum (Boulay) J.-P. Frahm are recorded as new for the moss flora of Turkey.

It has been proven, previously, that this problem of information system development order is in fact NP-complete, NP-hard, and APX-hard. To solve this problem on a general case we have previously developed Monte-Carlo randomized algorithm, calculated complexity of this algorithm, and so on. After previous research we were able to come into possession of digraphs that represent real-world information systems. Therefore, in this paper we will empirically analyze Monte-Carlo algorithm to determine how the algorithm works on real-world examples. Also, we will critically review the results and give some possible areas of future research as well.

Biomonitoring of Metal Deposition in the Vicinity of Eregli Steel Plant in Turkey

This article describes the first attempt to study the concentration of seven element (Fe, Pb, Ni, Cr, Cu, Co, and As) contaminations in the vicinity of the Eregli Iron and Steel Plant (ERDEMIR) by analysis of two pleurocarpic moss species (Hypnum cupressiforme and Scleropodium purum). Samples of H. cupressiforme were collected from May 2003 to October 2004. Unwashed, dried samples were digested with HNO3/HClO4, and the concentrations of heavy metals were determined by graphite–furnace atomic absorption spectrometry (GFAAS). In the region, general orders of heavy metal content in samples of mosses were determined as follows: Fe > Pb > Cr > Ni > Cu > Co > As. Comparisons were made between the two moss species for those elements presents at different concentrations and regression analysis were made to see interspecies relationship. H. cupressiforme and S. purum are significantly correlated for only Fe (P < 0.01) having Pearsons correlation coefficient as 0.93, indicating interspecies calibration for Fe. The ratios (Hc/Sp) were relatively better correlated with 1/Sp for As than for other metals, suggesting a saturation effect in H. cupressiforme for As. The deposition of metals due to the operation of the steel plant has been established and could be further monitored. Such information could be useful for forensic studies aiming to apportion between different possible sources of those metals.

Circumpolar boreal-montane moss Buxbaumia aphylla is a new species for Croatia. We have found 58 capsules and 12 setae at the three sites: the smallest population (10 specimens) was located at Sokolina ; at the two other sites B. aphylla was more abundant (Svinjarevac: 29 specimens, Konjska smrt: 31 specimens). Ricciocarpos natans is reported from several localities. It was discovered during extensive surveys of the macrophytic vegetation throughout Croatia. Based on our recent findings, the species occurs in northern and eastern Croatia, mostly in backwaters, or areas subject to inundation, of the large rivers Danube, Drava and Mura. According to our observations, the species in Croatia occupies relatively small and rather shallow eutrophic stagnant waters.

The Genus Pseudephemerum and Schistidium confusum Newly Reported from Turkey and Southwestern Asia

Abstract Pseudephemerum nitidum (Hedw.) Loeske (Ditrichaceae) and Schistidium confusum H.H.Blom (Grimmiaceae) were recorded for the first time in Turkey and Southwest Asia. Moreover, the genus Pseudephemerum (Lindb.) I.Hagen was recorded as new for this region, whereas Schistidium confusum was firstly reported from Mediterranean countries. Site descriptions, illustrations and diagnostic characters, ecology, geographic distribution of these species and brief comparisons with morphologically similar taxa were presented.
