The study uses ozone concentrations from stations in Warsaw Agglomeration and its vicinity. Diversity of localizations of considered station, in terms of type of emissivity, allows on comparison of air pollution conditions by ozone in Warsaw area. Concentration of ozone in summer and spring were above twice greater than the concentration in autumn and winter. The greatest differences between weekend days concentration and work days concentration occur during autumn and winter, but in the same time the differences during the day are the least, especially in urban site stations. Statistics analysis shows strong relationship between ozone concentration and nitrogen dioxide concentration and meteorological elements especially for days with high level of ozone concentration. For these days regression equations were statistically signifi cant (α = 1%) and correlation coeffi cients were greater than 0.81. Polynomial of IV power is the best fitted function of one-hourly values of ozone concentration course in particular seasons.

The aim of our study was to investigate the changes of metal concentrations in stream sediments depending on station and sampling period variation. Sediment samples were collected seasonally from six separate stations selected along Kilicozu Creek (Kirsehir, Turkey), and the Pb, Cr, Cu, Ni, Zn, and Cd concentrations were determined. Stations were selected on the basis of pollution gradient. It was observed that the metal concentration means per annum were Zn> Cr> Ni> Cu> Pb> Cd. Seasonal highest values of heavy metals were observed as follows; Pb (14.4 µg·g⁻¹), Ni (43 µg·g⁻¹), and Cd (6.2 µg·g⁻¹) in autumn, Cr (55.7 µg·g⁻¹) and Zn (71.9 µg·g⁻¹) in summer, and Cu (42.5 µg·g⁻¹) in spring. One-way ANOVA results also showed that there were significant metal concentration changes between stations. Potential metal contamination risk was determined for studied sediment samples. It was observed that Cd contamination exceeded the limit values in this stream sediment. According to the reference values, Zn or Pb contamination in the creek sediment has not reached the effective level. The findings of this study may be useful for further biomonitoring studies.

We make an attempt to consolidate results from a number of recent studies into spatial patterns of temporal variations in Baltic Sea wave properties. The analysis is based on historically measured and visually observed wave data, which are compared with the results of numerical hindcasts using both simple fetch-based one-point models and contemporary spectral wave models forced with different wind data sets. The focus is on the eastern regions of the Baltic Sea and the Gulf of Finland for which long-term wave data sets are available. We demonstrate that a large part of the mismatches between long-term changes to wave properties at selected sites can be explained by the rich spatial patterns in changes to the Baltic Sea wave fields that are not resolved by the existing wave observation network. The spatial scales of such patterns in the open sea vary from >500 km for short-term interannual variations down to about 100 km for long-term changes.

The trematode Echinostephilla patellae is an abundant but scarcely investigated parasite found in coastal ecosystems of the British Isles. Redial and cercarial stages of the digenean occur in the digestive gland and gonads of common limpets Patella vulgata. Here, we present data on the temporal distribution of E. patellae infections in P. vulgata from an intertidal site on the Irish south coast as well as on the intramolluscan development of the cercariae over a period of one year. Prevalence of infection showed temporal variation with a distinct peak in September, possibly related to an increase in the abundance of bird final hosts coinciding with comparatively high temperatures at the study locality during the summer months. Maturation of cercarial stages was strongly correlated with water temperature. Whilst fully developed cercariae were present in the rediae from May to November, large numbers of infective stages occurred in the limpets’ mantle blood vessels — where they accumulate prior to release — between June and September, suggesting this period of time to be the main transmission window for E. patellae cercariae.

A detailed ecological study was conducted for three years (2001–03) on a 5 km stretch of well-developed coral reef facing an industrial site in the southernmost section of the Jordanian coast of the Gulf of Aqaba, Red Sea. The degree of modification associated with the prevailing ecological factors was assessed with respect to species diversity and abundance of the major groups of the macrobenthic community: corals, bivalves, hydrozoans, echinoderms, sponges and macroalgae. Three locations of two depths each – 6 and 12 m – were selected and surveyed using the visual census point-intercept method. The actual area of the survey covered about 2250 m2. Macrobenthic communities occurring close to the industrial jetty were characterized by low diversity and the obvious dominance of soft coral (16–30% cover). In the deep transects (12 m) hard coral cover was higher than that in the shallow transects (30–55%). Correlation analyses indicated that species richness increased with increasing distance from the industrial jetty. Species richness of other macrobenthos was also higher as depth increased. The results revealed that the distribution and abundance of coral, echinoderms, hydrozoans and macroalgae were correlated with the relative importance of bottom modification within the various locations in the entire study area. However, no distinct influence of location or depth on the identities of most macrobenthic species was indicated.

Temporal variations (1994–98) in nutrient distribution were analysed in the Polish sector of the Baltic Sea with reference to long-term (1979–98) fluctuations of hydrological and chemical factors. Between 1994 and 1998 the winter accumulation of phosphate declined noticeably in most of the regions with the exception of the Gulf of Gdańsk. The winter peaks of silicate were also reduced in the offshore region and in the waters along the central Polish coast, but continued to accumulate in the bays owing to riverine input. In the offshore region a decrease in the winter accumulation of nitrate was noted in the surface water layer whereas in the bays nitrate concentrations continued to increase. Large quantities of nitrate continue to accumulate in the Gulf of Gdańsk, although at a slower rate than in 1979–93.

Natural populations of many species are increasingly impacted by human activities. Perturbations are particularly pronunced for large ungulates due in part to sport and commercial harvest, to reductions and fragmentation of native habitat, and as the result of reintroductions. These perturbations affect population size, sex and age composition, and population breeding structure, and as a consequence affect the levels and partitioning of genetic variation. Three case histories highlighting long-term ecological genetic research on mule deer Odocoileus hemionus (Rafinesque, 1817), white-tailed deer O. virginianus (Zimmermann, 1780), and Alpine ibex Capra i. ibex Linnaeus, 1758 are presented. Joint examinations of population ecological and genetic data from several populations of each species reveal: (1) that populations are not in genetic equilibrium, but that allele frequencies and heterozygosity change dramatically over time and among cohorts produced in successive years, (2) populations are genetically structured over short and large geographic distances reflecting local breeding structure and patterns of gene flow, respectively; however, this structure is quite dynamic over time, due in part to population exploitation, and (3) restocking programs are often undertaken with small numbers of founding individuals resulting in dramatic declines in levels of genetic variability and increasing levels of genetic differentiation among populations due to genetic drift. Genetic characteristics have and will continue to provide valuable indirect sources of information relating enviromental and human perturbations to changes in population processes.

To test the role of riparian ecotones in fish community dynamics three different sites along the Sorraia system, were selected. Each station has been under distinct anthropogenic pressure, and characterized by a mosaic of habitat conditions. Fish were collected by electrofishing from October 1991 to October 1993 using two distinct sampling scales, (50 m and small sectors defined according to discontinuities in the dominant vegetation). The variation in species abundance and distribution was correlated with physical factors. The results showed the preference of barbel and nase for riparian vegetation and greater depth and of roach for zones with macrophytic vegetation and high current velocity. Fish community of the Sorraia system does not exhibit a consistent pattern of temporal variation, what is usually observed in Southern streams of the Iberian Peninsula. This fact is probably related to the landscape disturbance.
