Opis:
The aim of this paper was to compare the species composition of mites in dust samples collected at different compartments of human dwellings of north-western (NW) Poland. In 30 urban apartments (Szczecin, Police, Pyrzyce and Łobez) and rural quarters (Przelewice, Brzesko Szczecińskie, Bylice, Krasne, Kąkolewice, Wierzchowo, Przeradz, Kłodzino) from NW Poland, 150 samples of dust were collected at 5 locations: bed area, bedroom carpet, sitting area in the living room, hall carpet, and kitchen floor. Mites were isolated using Berlese-Tüllgren extractors. The isolated dust mites belonged to the order Astigmata, families Pyroglyphidae: Dermatophagoides farinae Hughes, 1961, Dermatophagoides pteronyssinus (Trouessart, 1987), Euroglyphus maynei (Cooreman, 1950) and Hirstia Hull, 1931; Chortoglyphidae: Chortoglyphus arcuatus (Troupeau, 1879) and Glycyphagidae: Gohieria fusca (Oudemans, 1902), Lepidoglyphus destructor (Schrank, 1781), and the order Prostigmata, family Cheyletidae: Cheyletus (Latreille, 1796). The most frequently observed were the species D. farinae (58.9%) and the representatives of the genus Cheyletus (30.6%). Statistically significant differences were found between: the number and concentration of D. farinae in the dust collected from beds in the bedroom and dust from the carpet in the bedroom, living room, hall and kitchen; the number of D. farinae in samples from the carpet in the bedroom and from the kitchen floor; the number and concentration of D. farinae in the dust from the living room and the dust in the hall and kitchen; the number of Cheyletus sp. in samples of dust from bed areas in the bedroom and the samples from the carpet in the bedroom, hall and kitchen; the number and concentration of Cheyletus sp. in dust samples collected from the carpet in the bedroom and samples from the kitchen; the concentration of Cheyletus sp. in dust collected from bed areas and samples from the floor in the hall and kitchen; the number of D. pteronyssinus in dust samples collected from bed areas in the bedroom and samples from the carpet in the bedroom. In conclusion, the number of mites D. farinae, D. pteronyssinus and Cheyletus sp. depended on the place where the mites were sampled. The greatest numbers of these species were observed in the bed areas in bedrooms. The tests confirmed the high occurrence of house dust mites in the apartments in north-western Poland, especially in the bed areas in the bedroom.

Opis:
Bilansowanie popytu z podażą kruszyw żwirowo-piaskowych ze względu na niewielką cenę surowca i wysokie koszty jego transportu jest istotnym elementem regionalnej gospodarki kruszywami. Produkcja kruszyw żwirowo-piaskowych w skali regionu zależy w głównej mierze od wielkości posiadanych zasobów, które mogą być eksploatowane oraz od jakości złóż. Odbiorcy kruszyw zlokalizowani są w miejscach, gdzie jest na nie zapotrzebowanie, zależne od prowadzonych inwestycji. Popyt jest rozproszony i zmienny w czasie. W pracy analizie poddano wzajemne relacje między podażą kruszyw żwirowo-piaskowych w północno-zachodniej części kraju a popytem na ten surowiec. Mimo, że w analizowanym regionie występuje wiele złóż, to ich rozmieszczenie jest nierównomierne, a rejony zapotrzebowania nie pokrywają się z rejonami wydobycia. Powstają więc obszary o nadwyżkach podaży nad popytem oraz obszary deficytowe, w których zapotrzebowanie musi być zaspokajane dodatkowymi dostawami. W artykule omówiono metodę bilansowania produkcji i zużycia kruszyw żwirowo-piaskowych dla północno-zachodniej części Polski. Analizę dla trzech województw (zachodniopomorskie, pomorskie, kujawsko-pomorskie) wykonano w skali mniejszych jednostek terytorialnych — powiatów, przedstawiając możliwe kierunki dostaw kruszyw w skali regionalnej.
Balancing of demand and supply of gravel-sand aggregates is an important component of regional economy of aggregates due to low price of such raw materials and high costs of transportation. Production of gravel-sand aggregates in the regional scale depends largely on quantity of resources that can be exploited and quality of deposits. Recipients of aggregates are located in areas where aggregates are required, depending on current level of investments. The demand is dispersed and variable in time. In this paper the relationships between supply of gravel-sand aggregates in the north-western part of Poland and demand for this raw materials were analysed. Although there are many deposits in the region, their distribution is uneven, and the areas of demand do not coincide with areas of production. Thus, the areas of surplus of supply over demand can be noticed as well as deficit areas, where demand has to be met with supplies from other regions. This paper describes a method for balancing of production and consumption of gravel-sand aggregates for the north-western part of Poland. The analysis of the three provinces of the region (Zachodniopomorskie, Pomorskie, Kujawsko-Pomorskie) were made for smaller territorial units — counties, outlining possible options for supply of aggregates on the regional scale.

Opis:
Infections caused by the spirochete Borrelia burgdorferi sensu lato may be accompanied by other microorganisms, such as Anaplasma, Ehrlichia and Babesia. These pathogens are transmitted by the ticks and are a risk to humans and animals. Ixodes ricinus ticks collected from recreational areas of Szczecin and northwestern Poland contained DNA of the pathogens mentioned above and cases of double and triple coinfection have been documented. The aim of this paper was to determine if dogs suspect to tick infestation in the area of study are a reservoir for these pathogens and to examine the possibility of coinfection. Canine blood was sampled, part of the material originated from dogs exhibiting symptoms of borreliosis. In an earlier study, the samples were screened for DNA from B. burgdorferi sensu lato. In order to screen for A. phagocytophila and Babesia sp. DNA, a PCR-based method was used with the following primers: EHR521/EHR747 for Anaplasma and FOR1/REV1 for Babesia. In 192 samples only two contained A. phagocytophila DNA. One of these samples originated from a healthy canine, the other from an individual with symptoms of borreliosis. The examined samples were not positive for Babesia sp. DNA. Coinfection was not discovered. The low level of A. phagocytophila infection may indicate that the domestic dog is not a reservoir for Anaplasma and Babesia in Szczecin and northwestern Poland. Moreover, this area does not have populations of the brown dog tick (Rhipicephalus sanguineus) or Dermacentor reticulates — both of which are vectors of E. canis and B. canis and commonly induce ehrlichiosis and babesiosis in canines.

Opis:
The study involved a total of 250 wild ducks representing 17 species of three ecologically different tribes: the Anatini (113 individuals), the Aythyini (71), and the Mergini (66). The ducks, obtained mainly from fishermen and hunters, were examined for the presence of parasites, using the generally accepted methods. Analyses of nematode assemblage structure were conducted with methods described in the literature. In addition, significance of differences in intensity of infestation was determined in relation to the hosts’ age and sex as grouping variables. Significance of differences in infestation prevalence was tested with the Pearson Chi2 test or its modifications (V−square test, Chi2 test with Yates’ correction, and the exact Fisher’s test), while the Mann−Whitney U test was applied to infestation intensity and relative density. Similarity coefficients were ordered using the cluster analysis module of the STATISTICA 6.0® computer software; Ward’s algorithm was used for grouping, Euclidean distance being applied as the similarity measure. The ducks examined were found to host a highly diverse nematode assemblage, consisting of a total of 22 species representing the following 7 families: Amidostomatidae, Anisakidae, Ascarididae, Tetrameridae, Acuariidae, Dioctophymatidae, and Capillariidae, the core of the assemblage being formed by the following 7 species: Amidostomoides acutum, A. monodon, A. petrovi, Tetrameres fissispina, Echinuria uncinata, Eucoleus contortus, and Capillaria anatis. The assemblage of parasitic nematodes in the ducks examined was found to be characterized by a high organ specificity, as the parasites selected mainly the gizzard and proventriculus as their microhabitats (10 and 8 typical species, respectively) and firmly avoided the duodenum and cloaca. Individual parasite species were observed to show a clear preference with respect to location in the host’s alimentary tract, which means that, for a distinct majority of the parasitic species, typical sites could be identified. No significant effects of host’s age and sex on nematode infestation parameters could be revealed, although – in certain species – those variables proved of a key importance for their specificity. The nematodes showing a distinct preference towards young birds include E. uncinata and Ingliseria cirrohamata, a still higher specificity being displayed by T. fissispina and A. petrovi (selectively parasitising young females) and C. anatis (selective with respect to young males). The species which were more frequently recorded in the ducks aged two years and more, particularly in the adult males, included A. monodon and A. acutum. A clear relationship between the ecology of a host and the structure of its parasitic nematode assemblage was observed. Each of the tribes was distinct in the specific nematofauna of its members, each nematofauna possessing its own well-expressed core. The nematofauna of swimming ducks (Anatini) consisted of 11 species, the core being formed by A. acutum, E. uncinata, T. fissispina, and E. contortus. The diving ducks (Aythyini) were found to host 8 nematode species, the core being formed by A. petrovi, T. fissispina, and C. anatis. The nematofauna of the predacious Mergini was found to consist of as many as 17 species, although one of them (A. monodon) was a distinct dominant. The nematode fauna of those birds showed also a relatively high proportion of T. fissispina, the most polyxenic nematode, recorded in 10 host species of all the tribes studied. Although the problem of habitat partitioning between various components of a nematode assemblage could not be unambiguously resolved, it was evident that cases of co−occurrence involved mainly co−invasions at different sections of the alimentary tract of the same host, the strongest relations being found for those species that formed the core of a nematode assemblage. Co−invasions affecting a host’s organ concerned almost exclusively representatives of the families Amidostomatidae and Acuariidae in the gizzard and those of the Tetrameridae and Acuariidae in the proventriculus. The similarities between nematofaunas of the ducks studied are only weakly related to the systematic position of the respective ducks; much stronger relationships with ecological characteristics (mainly food type and feeding habits) were revealed. It seems that this is why the nematofauna of Common Goldeneye is much more similar to that of the Aythyini than to that of the Mergini to which the species is taxonomically assigned.

The aim of the research was to analyse land use changes and to develop a coherent base on the basis of available cartographic source materials - archival and contemporary topographic maps and spatial databases. The presented research is a continuation of works related to the cartographic visualization of changes in the distribution of the settlement network in the Noteć Forest - one of the largest forest complexes in Poland. The analysis was performed for nine villages together with their immediate surroundings, located in this area. The total surface area of lands covered by the study was 32,468 km2. Cartographic source materials were collected for selected areas. The archival maps were georeferenced and then digitized. In this way, the data has been transformed into a homogeneous system enabling further comparisons and analyses in an automated manner. Geodetic software (C-Geo), GIS (MapInfo, QGIS) and GNSS technology were used in the work. Cartographic sources can be successfully used for spatial analyses and environmental studies, providing reliable and available quantitative data. This type of research is important because it shows the changes taking place in the natural environment and can be used in works related to spatial planning, landscape ecology and social research.

Opis:
The study was aimed at investigations of the relationships growth-climate at two oak species growing in forests of north-western Poland; the red oak, the most abundant deciduous tree species of foreign origin, in terms of the appearance sites and surface, and the common oak, the most abundant domestic oak species. The research material were samples taken with a Pressler increment borer from 51 oak trees from two research plots. Within the surfaces selected, trees grow in a fresh forest habitat, in the floral association of the lowland fertile beech forest, also called the Pomerania beech forest, with plants characteristic for the association of the lowland humid beech forest with mercuries, encountered only in the Puszcza Bukowa (Beech Forest). The trees investigated were in good and very good health conditions, only scarce branch and bough deadwood could be observed in the canopies. On the basis of measurements of the annual growth widths, three local chronologies were constructed; two for the red oak and one for the common oak. After the indexation, they were used for dendroclimatical analyses; signature years, correlation and response function. The red oaks forming the shortest chronology (79-year-long pattern representing ca. 90-year-old trees) exhibited the narrowest mean annual increments (1.27 mm), in comparison to the longer chronologies (156 and 151 years in length, the increment widths 1.55 and 1.59 mm, respectively). This could be due to relatively high density of the tree stand, formation of the second stage, beneath the main canopies, as well as lack sufficient amount of the sunlight for the red oaks from that research plot. At both the species analysed, the predominating factor affecting the annual growth widths proved to be the amount of precipitation in the growth season, particularly in June and July, as well and thermal conditions of October of the year preceding the vegetation season in question. In the time of present climatic changes, as well as shifting ranges of the species of plants and animals (including insect pests of the forest trees), knowledge of the relation growth-climate for one of the foreign trees, most often introduced in Poland, characterized by fast growth, resistance on insect pests, and high quality of wood, becomes highly important for the forest management, particularly at planning seedlings, of which effects would be possible to evaluate in over 100 years.

This paper presents the dependence of air pollution with sulphur dioxide and nitrogen dioxide on wind direction in Szczecin, Łeba, Elbląg and Zielona Góra in the period 19931999. It has been shown that the most disadvantageous air quality conditions in the cities listed above are on the days with air inflow from south-east, and the most advantageous on the days with advection from north-west. This dependence is particularly evident in the case of pollution with sulphur dioxide, especially in the cold half-year.
