Fish are good indicators of long-term changes of fluvial ecosystems therefore, assessment of fish assemblages is frequently used in evaluation of the ecological status of surface waters, especially since the implementation of the EU Water Framework Directive. Long-term changes of fish fauna and old-time abundance of fish populations in the Danube can be documented by historical data of fisheries. Direct detection of long-term changes of fish populations in large rivers is a difficult task due to...

In recent years, many studies investigated how density-dependent factors, such as shortages in microhabitat and food availability influence the structure of reef fish assemblages. Most of what is currently known, however, comes from comparisons of isolated patch reefs and from correlations between fish abundance and one or few microhabitat variables. In addition, most studies were done in the Caribbean and Indo-Pacific regions, whereas the South Atlantic region has been, to date, understudied. T...

An indispensable component of ensuring safe control of railway and sea transport in conditions of hot climate is maintenance of comfortable temperature of air in control cabins and living spaces. Now the interest is restored to use the Air Refrigerating Plants (ARP) as they have a wide potential of low-temperature cooling without use of ozone-destructive cooling agents prohibited by decision of the Montreal meeting. At the same time, air conditioning installations on the basis of turbo-expanders...

The present study concerns the 3-D distribution of pollutants emitted from a coastal outfall in the presence of strong sea currents. The problem is solved using the nonlinear Reynolds-averaged Navier–Stokes equations in the framework of the <i>k</I>-<i>ε</i> model. The constants of the logarithmic law for the vertical velocity profile in the bottom boundary layer are obtained by processing experimental data from acoustic Doppler current profilers (ADCPs). The near-field distribution of pollutant...

Shelves have been estimated to account for more than one-fifth of the global marine primary production. It has been also conjectured that shelves strongly influence the oceanic absorption of anthropogenic CO<sub>2</sub> (carbon shelf pump). Owing to their coarse resolution, currently applied global climate models are inappropriate to investigate the impact of climate change on shelves and regional models do not account for the complex interaction with the adjacent open ocean. In this stud...

This paper proposes a statistical model for mapping global landslide susceptibility based on logistic regression. After investigating explanatory factors for landslides in the existing literature, five factors were selected for model landslide susceptibility: relative relief, extreme precipitation, lithology, ground motion and soil moisture. When building the model, 70 % of landslide and nonlandslide points were randomly selected for logistic regression, and the others were used for model ...

Most studies of coral reproductive biology to date have focused on oocyte numbers and sizes. Only one (ex situ) study has enumerated sperm numbers, even though these data have multiple potential applications. We quantified total coral sperm and eggs per gamete bundle collected from six species in situ during a synchronous spawning event in Singapore. Egg-sperm bundles were captured midwater as they floated towards the surface after being released by the colony. For each sample, a semi-transparen...

Coastal environments are trampled by humans worldwide; however, there are few studies that evaluate the effect of trampling on the meiofauna of hard substrates, and none on meiofauna of reef environments. We investigated the effects of trampling due to tourism on the meiofauna of reef formations on the northeastern coast of Brazil. Samples were taken from five paired stations located in two areas on the reef: an area protected since 2004, and an area open to tourist visits. Trampling caused impo...

Object recognition is a very interesting task with multiple applications and for that reason it has been dealt with very intensively in the last years. In particular, the application to naval ship pictures may facilitate the work of the coastguards or the navy. However, this type of images entails some difficulties due to their specific environment. Water reflects the light and as a consequence, some areas may presumably show different brightness and color. Waves from wind or moving ships pose a...

In previous field studies the B1 and B12 demand of this species was suggested but not experimentally verified. When the axenic vitamin un-supplemented culture (B-ns) of L. polyedrum was inoculated with a coastal bacteria community, the dinoflagellate's vitamin growth limitation was overcome, reaching the same growth rates as t...

Lymph nodes and spleen are major organs where mammalian APCs initiate and orchestrate Ag-specific immune responses. Unlike mammals, teleosts lack lymph nodes and an interesting question is whether alternative organs may serve as sites for antigen presentation in teleosts.

The relationship between the annual wind records from a weather station and annual mean sea level in an inter-tidal basin, the Dutch Wadden Sea, is examined. Recent, homogeneous wind records are used, covering the past 2 decades. It is demonstrated that even such a relatively short record is sufficient for finding a convincing relationship. The interannual variability of mean sea level is largely explained by the west–east component of the net wind energy, with some further improvement if...

The Lena River integrates biogeochemical signals from its vast drainage basin, and the integrated signal reaches far out over the Arctic Ocean. Transformation of riverine organic carbon (OC) into mineral carbon, and mineral carbon into the organic form in the Lena River watershed, can be considered to be quasi-steady-state processes. An increase in Lena discharge exerts opposite effects on total organic (TOC) and total inorganic (TCO<sub>2</sub>) carbon: TOC concentration increases, while TCO<su...

Padrões na diversidade de peixes ao longo de quatro unidades geográficas (superior, médio-superior, médio-inferior e inferior) no rio Paraíba do Sul foram estudados com a finalidade de avaliar tendências de variações espaciais (unidades geográficas) e temporais (períodos de cheia e seca). Vinte e cinco locais foram amostrados entre Dezembro de 2002 e Março de 2003 (verão/cheia) e, entre Agosto e Novembro de 2003 (inverno/seca). Os peixes foram capturados com um esforço padronizado, utilizando re...

The last deglaciation is one of the best constrained global-scale climate changes documented by climate archives. Nevertheless, understanding of the underlying dynamics is still limited, especially with respect to abrupt climate shifts and associated changes in the Atlantic meridional overturning circulation (AMOC) during glacial and deglacial periods. A fundamental issue is how to obtain an appropriate climate state at the Last Glacial Maximum (LGM, 21 000 yr before present, 21 ka BP) that can ...

Statistical analysis of natural hazards needs particular attention, as most of these phenomena are rare events. This study shows that the ordinary rare event logistic regression, as it is now commonly used in geomorphologic studies, does not always lead to a robust detection of controlling factors, as the results can be strongly sample-dependent. In this paper, we introduce some concepts of Monte Carlo simulations in rare event logistic regression. This technique, so-called rare event logistic r...

The research was conducted in the mangrove coastal water in Peniti, West Kalimantan. Peniti mangrove coastal water has high species richness and diversity of polychaetes. We have collected 43 species of polychaetes. Most of them are deposit feeders with Dodecaceria sp. and Sternaspis scutata showed highest abundance among all species. The substrate characteristic was muddy-clay and the high carbon organic content.

This paper discusses existing models of long-wave radiation exchange between the sea surface and the atmosphere, and compares them with experimental data. The latter were based on empirical data collected in the southern Baltic during cruises of r/v `Oceania'. To a greater or lesser extent, all the models were encumbered with significant systematic and statistical errors. The probable reasons for these discrepancies are given.

Mirror therapy (MT) has been recommended as a simple, inexpensive approach to treat motor dysfunction. The use of a mesh glove (MG) was suggested to normalize muscle tone that ameliorates motor impairment. Combining two efficient treatment protocols might maximize the benefits from training. This study investigated the effects of MT combined with MG (MG + MT) versus MT alone on motor performance and daily function after stroke. Methods: Sixteen patients with chronic unilateral stroke were recrui...

For the design and optimisation of offshore wind turbines, the knowledge of realistic environmental conditions and utilisation of well-founded simulation constraints is very important, as both influence the structural behaviour and power output in numerical simulations. However, real high-quality data, especially for research purposes, are scarcely available. This is why, in this work, a comprehensive database of 13 environmental conditions at wind turbine locations in the North and Baltic...

Coastal ecosystems produce and store carbonate particles, which play a significant role in the carbonate dynamics of coastal areas and may contribute to the sediment budget of adjacent beaches. In the nearshore seabed of temperate zones (e.g. Mediterranean Sea and South Australia), marine biogenic carbonates are mainly produced inside seagrass meadows. This study quantifies the contribution of biogenic sediments, mainly produced in <i>Posidonia oceanica</i> seagrass meadows and secondarily...
