Abstract:
Five new species of the genus Trechus Clairville, 1806 are described from the eastern part of the Tien Shan mountains (China, Xinjiang-Uygur Autonomous Region): T. tsanmensis sp. n. from the Narat Mountain Range, left bank of the Zanma River; T. torgaut sp. n. from the upper course of the Kunges River and Narat Mountain Range (both species belong to the uygur species group, which is defined here); T. aghiazicus sp. n. from the Aghiaz River and Koeksu Basin, T. cratocephalus sp. n. from the Narat Mountain Range (both belong to the micrangulus species group); and T. saluki sp. n. from the mountains S of the Kunges River (belonging to the kashensis species group, also defined in the present paper). Some new data on the distribution of T.uygur Deuve, 1993 and T. kashensis Belousov & Kabak, 2001 are given. The distribution of all known species of the uygur and kashensis groups is mapped. An identification key is provided to known species of the uygur group.

Abstract:
A water sample was taken once a day for 15 months at a site near an estuary of the Kako River, Japan, to estimate nutrient loads from rivers to the sea. Total phosphorus (T-P), total nitrogen (T-N), suspended solids (SS) and electronic conductivity (EC) were measured. T-P and SS concentrations varied in proportion to the discharge, and T-P concentrations increased with those of SS, too. EC varied inversely with the discharge, but the fluctuations of T-N concentrations were less than those of T-P and SS concentrations. Water quality remained, for the most part, constant throughout the day. T-P, T-N and SS load were 181t/year, 2320t/year and 51000t/year in 1992, respectively, 54% of T-P load, 47% of T-N load and 80% of SS loads outflowed in those cases where the discharge was more than 100 m3/s, which were 36 days in 1992. 79% of T-P load, 69% of T-N load and 92% of SS load outflowed in periods of high water discharge, which were 88 in 1992. T-P and T-N loads calculated by using one day's data in every month were 151t/year and 2450t/year. But nutrient loads calculated by using the average value of data from an ordinary discharge were two or three times lower than calculated yearly loads. These results showed the importance of estimating the yearly load considering the discharge condition and sampling at a time of high water discharge.

Abstract:
The main goal of the present paper is to define the kozlovi-species group of the genus Trechus Clairville, 1806, one of the most species-rich groups of Chinese Trechus and to describe new species of this group from two neighboring areas in Sichuan Province. Description of species groups for Chinese Trechus is a way to get a more consistent view of the taxonomy of this extremely diverse genus. The kozlovi group includes many described species, which are widespread in Qinghai, Gansu and Sichuan provinces. In turn, the group can be split into several subgroups each embracing close allopatric relatives but much more material from various areas of China is required for such detailed classification. In the present work, we describe 9 new Trechus species belonging to this group, all collected in central and southern Sichuan, China: T. suopoensis sp. n. and T. gemaensis sp. n., both from the northern slopes of Mount Gema, E of Danba City, T. bianericus sp. n. and T. maoniu sp. n., both from the nortwestern slopes of the mountain massif located south of Bianer Village, WNW of Danba City, T. shangensis sp. n., T. mengensis sp. n., both from the upper valley of the small river located WSW of the village of Shangmeng, NW of Lixian City, T. cuspis sp. n. from the southern slope of Mount “5200” NW of Lixian City, three latter species from the left bank of the Zagunao River, T. qunlaishanicus sp. n. from the Qunlaishan mountains on the right bank of the Zagunao River and T. chiguguanensis sp.n. from the Chiguguan Pass.

Abstract:
Twenty-four rivers in different parts of Lithuania were selected for the study. The aim of the research was to evaluate the impact of anthropogenic load on the ecological status of rivers. Anthropogenic loads were assessed according to the pollution sources in individual river catchment basins. The total nitrogen (TN) values did not correspond to the “good” and “very good” ecological status classes in 51% of the tested water bodies; 19% had a “bad” to “moderate” BOD7, 50% had “bad” to “moderate” NH4-N, 37% had “bad” to “moderate” NO3-N, and 4% had “bad” to “moderate” PO4-P. The total phosphorus (TP) values did not correspond to the “good” and “very good” ecological status classes in 4% of the tested water bodies. The largest amounts of pollution in river basins were generated from the following sources: transit pollution, with 87,599 t/year of total nitrogen and 5020 t/year of total phosphorus; agricultural pollution, with 56,031 t/year of total nitrogen and 2474 t/year of total phosphorus. The highest total nitrogen load in river basins per year, on average, was from transit pollution, accounting for 53.89%, and agricultural pollution, accounting for 34.47%. The highest total phosphorus load was also from transit pollution, totaling 58.78%, and agricultural pollution, totaling 28.97%. Multiple regression analysis showed the agricultural activity had the biggest negative influence on the ecological status of rivers according to all studied indicators.

Abstract:
Land-based total nitrogen (N) loadings to Danish coastal waters have been markedly reduced since 2000. This has been achieved by general measures reducing discharges from all point sources and N leaching from farmed land supplemented with more local and targeted mitigation measures such as restoration of wetlands to increase the catchment-specific N retention. In the catchment of River Odense, restoration of wetlands has been extensive. Thus, in the major gauged catchment (485 km2) eleven wetlands (860 ha) have been restored since 2000. A comparison of data on N concentrations and loss from a gauging station in the River Odense with data from a control catchment (772 km2), in which a significantly less intensive wetland restoration programme has been undertaken, showed an excess downward trend in N, amounting to 124 t N yr−1, which can be ascribed to the intensive wetland restoration programme carried out in the River Odense catchment. In total, the N load in the River Odense has been reduced by 377 t N yr−1 (39%) since 2000. The observed downward trend is supported by monitoring data from two wetlands restored in 2001 and 2004 in the River Odense catchment.

Descriptions and illustrations of Terschellingia longisoma sp. n. and Sphaerotheristus parvus sp. n. are given. T. longisoma sp. n. is close to T. siphonolaimoides (Wieser, 1956) and T. capitata Vitiello, 1969. It differs from T. siphonolaimoides in the shorter and thinner body, shorter cephalic setae, absence of cervical setae, position of vulva, and from T. capitata in the longer and thinner body, shorter and thicker tail and larger amphidial fovea. S. parvus sp. n. is close to S. supoti Timm, 1968, but differs from it in the shorter stoma and shorter and differently shaped spicules.

Abstract:
Abstract. We present data from a comprehensive investigation carried out from 2007 to 2010, focussing on nitrogen pollution in the lower Oglio River basin (3800 km2, Po plain, Northern Italy). Nitrogen mass balances, computed for the whole basin with 2000 and 2008 data, suggest a large N surplus in this area, over 40 000 t N yr−1, and increasing between 2000 and 2008. Calculations indicate a very large impact of animal husbandry and agricultural activities in this watershed, with livestock manure and synthetic fertilizers contributing 85 % of total N inputs (about 100 000 t N yr−1) and largely exceeding crop uptake and other N losses (about 60 000 t N yr−1). Nitrogen from domestic and industrial origin is estimated as about 5800 and 7200 t N yr−1, respectively, although these loads are overestimated, as denitrification in treatment plants is not considered; nonetheless, they represent a minor term of the N budget. Annual export of nitrogen from the basin, calculated from flow data and water chemistry at the mouth of the Oglio River, is estimated at 13 000 t N yr−1, and represents a relatively small fraction of N inputs and surplus (~12 % and 34 %, respectively). After considering N sinks in crop uptake, soil denitrification and volatilization, a large excess remains unaccounted (~26 000 t N yr−1) in unknown temporary or permanent N sinks. Nitrogen removal via denitrification was evaluated in the Oglio riverbed with stable isotope techniques (δ15N and δ18O in nitrate). The downstream final segment of the river displays an enriched nitrate stable isotope composition but calculations suggest a N removal corresponding to at most 12 % of the unaccounted for N amount. Denitrification was also evaluated in riverine wetlands with the isotope pairing technique. Areal rates are elevated but overall N removal is low (about 1 % of the missing N amount), due to small wetland surfaces and limited lateral connectivity. The secondary drainage channel network has a much higher potential for nitrogen removal via denitrification, due to its great linear development, estimated in over 12 500 km, and its capillary distribution in the watershed. In particular, we estimated a maximum N loss up to 8500 t N yr−1, which represents up to 33 % of the unaccounted for N amount in the basin. Overall, denitrification in surface aquatic habitats within this basin can be responsible for the permanent removal of about 12 000 t of N per year; but the fate of some 14 000 t remains unknown. We provide evidences that an important N sink in this basin could be represented by groundwater. In the short term, the aquifers can store nitrogen and available data on nitrate concentration in wells support this hypothesis. In the mid-long term, part of the accumulated nitrate can be substantially recycled via springs and can pollute surface waters via river-groundwater interactions. This probably explains the ten fold increase of nitrate concentration in a reach of the lower Oglio River where no point pollutions sources are present.

Abstract. In this paper, we estimate the surface water retention of nitrogen (N) in all the 117 drainage basins to the Baltic Sea with the use of a statistical model (MESAW) for source apportionment of riverine loads of pollutants. Our results show that the MESAW model was able to estimate the N load at the river mouth of 88 Baltic Sea rivers, for which we had observed data, with a sufficient degree of precision and accuracy. The estimated retention parameters were also statistically significant. Our results show that around 380 000 t of N are annually retained in surface waters draining to the Baltic Sea. The total annual riverine load from the 117 basins to the Baltic Sea was estimated at 570 000 t of N, giving a total surface water N retention of around 40%. In terms of absolute retention values, three major river basins account for 50% of the total retention in the 117 basins; i.e. around 104 000 t of N are retained in Neva, 55 000 t in Vistula and 32 000 t in Oder. The largest retention was found in river basins with a high percentage of lakes as indicated by a strong relationship between N retention (%) and share of lake area in the river drainage areas. For example in Göta älv, we estimated a total N retention of 72%, whereof 67% of the retention occurred in the lakes of that drainage area (Lake Vänern primarily). The obtained results will hopefully enable the Helsinki Commission (HELCOM) to refine the nutrient load targets in the Baltic Sea Action Plan (BSAP), as well as to better identify cost-efficient measures to reduce nutrient loadings to the Baltic Sea.

<em>Abstract</em>.—The largest native population of Shoal Bass <em>Micropterus cataractae</em> inhabits the Flint River, Georgia and remains relatively unstudied. We examined demographic characteristics of the population in the lower Flint River that is bounded by reservoirs during 2009–2011. We anchor tagged 741 Shoal Bass to evaluate the percentage of caught fish that were harvested. Shoal bass (<em>n</em> = 187) were sacrificed for age and growth analysis. Ages of sampled fish ranged from age 1 to 11. Von Bertalanffy growth parameter estimates were <EM>L</EM><sub>∞</sub> = 564 mm, <EM>K</EM> = 0.312, and<em> t</em><sub>0</sub> = –0.089. Male and female growth rates were similar, with the mean Shoal Bass requiring 2.4 years to reach 305 mm and 5.1 years to reach 457 mm. Growth rates of Shoal Bass were greater than those of previously studied populations and Largemouth Bass <em>M. salmoides</em> in the Flint River and an impoundment bounding the upper end of the study site. Annual total pooled mortality was 49%. Forty-one percent of caught Shoal Bass were harvested by anglers (range 31–60%). Our results suggest that with current population characteristics, an increase in the minimum length limit would not increase yield to the recreational fishery.

Abstract:
ABSTRACT We report the results of 167 calcite twinning strain analyses (131 limestones and 36 calcite veins, n = 7368 twin measurements)t from the Teton–Gros Ventre (west; n = 21), Wind River (n = 43), Beartooth (n = 32), Bighorn (n = 32), and Black Hills (east; n = 11) Laramide uplifts. Country rock limestones record only a layer-parallel shortening (LPS) strain fabric in many orientations across the region. Synorogenic veins record both vein-parallel shortening (VPS) and vein-normal shortening (VNS) fabrics in many orientations. Twinning strain overprints were not observed in the limestone or vein samples in the supracrustal sedimentary veneer (i.e., drape folds), thereby suggesting that the deformation and uplift of Archean crystalline rocks that form Laramide structures were dominated by offset on faults in the Archean crystalline basement and associated shortening in the midcrust. The twinning strains in the pre-Sevier Jurassic Sundance Formation, in the frontal Prospect thrust of the Sevier belt, and in the distal (eastern) foreland preserve an LPS oriented approximately E-W. This LPS fabric is rotated in unique orientations in Laramide uplifts, suggesting that all but the Bighorn Mountains were uplifted by oblique-slip faults. Detailed field and twinning strain studies of drape folds identified second-order complexities, including: layer-parallel slip through the fold axis (Clarks Fork anticline), attenuation of the sedimentary section and fold axis rotation (Rattlesnake Mountain), rotation of the fold axis and LPS fabric (Derby Dome), and vertical rotations of the LPS fabric about a horizontal axis with 35% attenuation of the sedimentary section (eastern Bighorns). Regional cross sections (E-W) across the Laramide province have an excess of sedimentary veneer rocks that balance with displacement on a detachment at 30 km depth and perhaps along the Moho discontinuity at 40 km depth. Crustal volumes in the Wyoming Province balance when deformation in the western hinterland is included.

Abstract.<em>—</em>Our objectives were to study habitat use of different life stages of the burbot <em>Lota lota </em>L. in lowland rivers and to develop habitat models to assess possible reintroduction sites in Flanders, Belgium. Summer habitat use of subadult and adult burbot was studied in lowland rivers in northeast France in the Meuse basin. Highest burbot densities were found in the upper river parts over several watersheds. Adult and subadult burbot showed a strong preference for microhabitats characterized by undercut banks and cover by tree roots. Habitat use of larvae and fingerlings was studied in spring. Both larvae and fingerlings were exclusively found in small tributaries (width < 2 m). Fingerlings mainly occupied tributaries with low to moderate flow velocity (0.05–0.15 m/s) and high densities of vegetation (>25%). Winter spawning migration was studied using fyke nets. Adult burbot migrated into the deepest tributaries and upstream migration was highest at increased water levels or flows. Analysis of water quality requirements revealed that both nitrate (NO<sub>3</sub><sup>–</sup>) and total nitrogen (N<sub><em>t</sub></em>) content negatively influenced burbot densities. With these results, two models to evaluate habitat suitability of lowland rivers for burbot were developed and tested. The use of these models to evaluate potential reintroduction sites for burbot in Belgium is discussed.

Abstract:
The target of our present research is to develop a river monitoring instrument equipped with electricity power generator to supply for its own demand by utilizing energy of flow of the river. To apply this instrument to natural river, its generator should be simple, small and durable with wide flow velocity range of operation. In this paper, the vibration induced by the trailing vortex (T-VIV) on a cruciform circular-cylinder/strip-plate system is firstly introduced compared with the well-known Ka´rma´n vortex excitation (K-VIV). Secondly, a design for a generator utilizing the T-VIV is presented. Thirdly, an estimation technique for electricity power extracted from the vortex induced vibration (VIV) and a design guide for power generation module obtaining the maximum power are proposed. Finally, using the estimation technique to the T-VIV in air, an estimation of oscillation behavior and power generation performance of an T-VIV generator module applied to water flow are presented.

Abstract:
Elena Logunova1Master of Urban Planning, Post-graduate student, 1Department of Urban Design and Planning, School of Architecture and Design, Siberian Federal University Address: 79 Svobodny pr., 660041 Krasnoyarsk, Russian Federation E-mail: ikukina@inbox.ru , el.lgnv@yandex.ruScientific adviser: Pd.D., Professor - I. V. Kukina Keywords: fringe-belt, Siberia, urban morphology, fixation lineConference topics and scale: Tools of analysis in urban morphologyThe fringe-belt concept is one of the most important concepts in urban morphology which provides a possibility to analyze existing urban layout. Urban fringe-belt phenomenon in cities of Siberia hitherto was poorly investigated. Thus, it constitutes an extremely broad research area.Phases and processes of formation, transformation and alienation in urban fringe-belts examines at the case of Krasnoyarsk from the 17th to mid 20th centuries. Krasnoyarsk was founded as a military stockaded town in 1628 during the first period of Siberia development and experienced several historical stages in the process of urban growth.Relation of changes in fringe-belts structure and political and socio-economic contexts is evidently at all periods of their physical formation. Natural fixation lines (topographic features, body of big river, and development of small river valley) and man-made fixation lines (city walls, railway corridor) influenced to the formation and evolution processes of fringe-belts and urban fabric generally. Railway was a turning point in the city expansion and contributed to overcoming of the power natural fixation line as the Yenisei river. Unlike the urban core, right bank of Krasnoyarsk formed as a linear city with specific fringe belts.Detailed analysis of Krasnoyarsk city plan indentifies several morphological units separated by fringe-belts. These fringe-belts are characterized by distinctive road network, variety of land-use units and heterogeneous forms in plan. It presents difficulties for reconstruction projects of modern city. An approach for renovation of these territories needs to depend on urban morphology methodology. ReferencesConzen M. P., Kai Gu, Whitehand J. W. R.
