Opis:
Seeds of ten cultivars of spring wheat from five different localized breeding stations were tested for seedhealth. The same seeds were sown in Radzików in field experiment and its seed health after harvest was evaluatedalso. The basic material of wheat was infected by numerous fungi: 36 fungal species belonging to 24genera and the most often occurred: Alternaria alternata, Epicoccum purpurascens, Fusarium spp.,Drechslera spp. and B. sorokiniana. It was found significant differences between cultivars for total fungioccurred on seeds, for seed infection by main pathogens (B. sorokiniana, Drechslera spp. and Fusariumspp.). Also seeds from breeders were strongly infected by these pathogens in comparison to seeds harvested infield experiment in Radzików.

Opis:
The aim of the present study was to collect data from Eastern Slovak Lowland, southern Slovakia, to assess risk of the spread of canine dirofilariosis. Climate and environmental conditions in the Eastern Slovak Lowland are ideally suitable for the occurrence of vector-borne diseases. In the past, an endemic locality of dangerous mosquito transmitted malaria was found in this area. Today, another zoonotic parasitic disease threatens – dirofilariosis. The results of the first detailed study revealed a 34.44% prevalence in dogs harbouring dirofilariae. D. repens was diagnosed in all infected specimen, with 2 individuals being co-infected also with D. immitis.

Opis:
Soybean (Glycine max (L.) Merrill.) yielding potential depends on environmental conditions (precipitation, temperature, soil). The aim of the work was to evaluate stability of yielding (and other traits) of three soybean cultivars (Abelina, SG Anser, Merlin) grown under the climatic conditions of central-eastern Poland. The studied material was obtain in a field experiment conducted at Łączka (52°15' N, 21°95' E) during the growing seasons of 2017-2019. Trait stability was determined based on Shukla’s genotype stability variance and Wricke’s ecovalence describing the genotype-by-environment interaction. For all the examined parameters, there were found significant differences between successive growing seasons, cultivars, and cultivars within study years. The greatest influence of environmental conditions (years) was determined for plant height (64%) and first pod height (54.2%). Stability parameters indicated that cv. Abelina was the most stable in terms of yielding, 1000 seed weight, seed number per pod and average seed number per pod, cv. SG Anser being the least stable in this respect.

Opis:
Przedmiotem niniejszego artykułu jest analiza i szczegółowa wykładnia przepisów ustawy z dnia 3 października 2008 r. o udostępnianiu informacji o środowisku i jego ochronie, udziale społeczeństwa w ochronie środowiska oraz o ocenach oddziaływania na środowisko (Dz.U. z 2020 r., poz. 283) dotyczących uzgadniania decyzji o środowiskowych uwarunkowaniach. Poruszana w artykule problematyka jest ważna zarówno z teoretycznego, jak i praktycznego punktu widzenia. Odnosi się bowiem do ciągłego tworzenia się szczególnej procedury administracyjnej, jaką jest „postępowanie w sprawach środowiskowych”. Istotna jest również praktyka stosowania wspomnianych przepisów. Oceny oddziaływania na środowisko odgrywają bowiem kluczową rolę w procesie inwestycyjnym.
The subject of this article is the analysis and detailed interpretation of the provisions of the Act of 3 October 2008 on the provision of information about the environment and its protection, public participation in environmental protection and environmental impact assessments (Journal of Laws of 2020, item 283) concerning reconcilation decisions on environmental conditions. The issues discussed in the article are important both from the theoretical and practical point of view. It refers to the continuous development of a specific administrative procedure, which is the “procedure in environmental matters”. The practice of applying the above-mentioned provisions is also important. Environmental impact assessments play a key role in the investment proces.

Opis:
The environmental characterization of the Lower Permian mesosaur−bearing strata of the Mangrullo Formation (Paraná Basin, northeastern Uruguay) has been controversial. Historically, marine conditions were suggested for this unit, despite the absence of any normal marine fossils. More recently, some authors have argued for freshwater to brackish settings, inferring fluctuating environmental conditions, which would have generated abrupt changes in the composition of the communities. Mesosaurs are the only tetrapods found in this unit, and they colonized the basin at the time of highest isolation, and apparently increased salinity, coincident with a gradual global rise in aridity. An assemblage of extremely low diversity (the “mesosaur community”) developed, with mesosaur reptiles, pygocephalomorph crustaceans, and the vermiform producers of the trace fossil Chondrites as the dominant components. This community may have existed under temporary hypersaline, lagoon−like conditions, as suggested by ecological, anatomical and physiological attributes of its member taxa. This interpretation is supported by sedimentological and mineralogical features of the enclosing rocks, also seen in the correlative Brazilian Iratí and South African Whitehill formations. In the Uruguayan deposits, as well as in their Brazilian correlatives, relatively close volcanic events affected the basin. This particular environment, where bottom waters were depleted of oxygen and hypersaline, retarded decay of the carcasses, and precluded the development of bioturbating organism, and together with bacterial sealing, favoured exquisite preservation of the fossils, including soft tissues. This leads us to consider the fossil−bearing strata of the Mangrullo Formation as a Konservat−Lagerstätte, the oldest known for South America.

Opis:
Bacterial production, primary production and a number of other environmental factors were measured during six cruises in the Gulf of Gdańsk conducted in various seasons from 1995 to 2001. Bacterial production (BP) in the epipelagic layer ranged from 1.5% (April) to 80% (July) of the gross primary production (PP). Significant differences were observed between the BP/PP ratios in estuarine and open-water areas. The highest values were recorded in the coastal area and near the mouth of the river Vistula. It suggests that allochthonous organic matter has a great influence on BP. The correlations between particular parameters and regression analyses indicated that BP in the Gulf of Gdańsk depended on temperature, organic nitrogen concentration, PP, chlorophyll a concentration, organic phosphorus concentration, salinity and biochemical oxygen demand. Of all the independent variables, the temperature had the greatest impact on BP (R2 = 0.62). There was an inverse parabolic relationship between bacterial production and temperature. It appears that above a temperature of 12◦C bacterial production depended on substrates to a higher degree than on temperature. The negative correlation between BP and concentrations of mineral nitrogen and phosphorus in the annual cycle were probably due to an indirect dependence. A multiple regression equation, which included temperature and organic phosphorus concentrations, explained 78% of the variation in BP. Increasing BP resulted in an increasing biomass of bacterivorous nanoflagellates and of bacterivorous ciliates, which is indicative of bottom-up control in this segment of the trophic chain.

Opis:
The research was carried out on the Experimental Farm in Uhrusk, which belongs to the University of Life Sciences in Lublin. Two-year experiment were conducted in order to assess the influence of environmental conditions on the selenium content in sheep. The investigations included meadows grazed by sheep, from which samples of soils and meadow herbage were obtained for analysis of selenium content. The animal material consisted of 64 lambs and their mothers, whose blood serum was taken for determinations of the selenium content in their organism. The research results showed that the analyzed soils and meadow grasses were characterized by low selenium content. Also, the selenium content in fodder fed to the sheep and lambs was below the animals’ standard demand for this element. The low selenium level found in the sheep’s blood serum distinctly proved a deficiency of this element in their organisms. The results show that environmental conditions have a significant influence on the supply of selenium to adult sheep and their offspring. Selenium deficiency in particular trophic chain links can present a serious threat to the health of animals fed with homegrown fodders.
Eksperyment przeprowadzono w Gospodarstwie Doświadczalnym w Uhrusku należącym do Uniwersytetu Przyrodniczego w Lublinie. W cyklu dwuletnim oceniano wpływ warunków środowiskowych na zawartość selenu w organizmie owiec. Z łąk przeznaczonych do wypasu owiec pozyskano próbki gleby i roślin łąkowych, a następnie poddano analizie na zawartość selenu. Materiał zwierzęcy stanowiły 64 jagnięta i ich matki, od których pobrano krew w celu pozyskania surowicy do oznaczania zawartości selenu. W badanych glebach i florze łąkowej wykazano niską zawartość selenu. Również zawartość selenu w paszy dla owiec i jagniąt była poniżej zapotrzebowania zwierząt na ten pierwiastek. Niska koncentracja selenu w surowicy krwi badanych zwierząt wyraźnie wskazuje na niedobór tego mikroelementu w ich organizmach. Z badań wynika, że uwarunkowania środowiskowe mają istotny wpływ na podaż selenu dla dorosłych owiec i ich potomstwa. Niedobór selenu w poszczególnych ogniwach łańcucha pokarmowego może stanowić poważne zagrożenie dla zdrowia zwierząt karmionych paszami produkowanymi lokalnie.

Opis:
Plant reinforced composites are more widely introduced in the automotive or construction industry. Due to good thermal and acoustic insulation, low weight, economical and ecological benefits and limitations resulting mostly from low mechanical strength, they are used primarily as elements, which do not carry heavy loads. Yet, they perform decorative and insulating functions. Expanding the spectrum of usage is connected with analysing properties of these materials in various application conditions. The following article presents results of static tensile tests of composites reinforced with jute, linen and cotton used in changeable environmental conditions. The significance of influence exerted by such factors as water, hydraulic oil, technical lubricant and conditions of moderate climate were evaluated. Taking into account the potential possibilities of using composites with natural reinforcement in aircraft construction, e.g. in helicopters, the influence exerted by direct impact of aviation fuel were tested. It was concluded that different application conditions subject to research do not exert an identical influence on tested composites. Statistically significant influence on the change of tensile strength is exerted while application of cotton composites in water. Composites with jute lose their properties during usage in autumn moderate climate and in hydraulic oil. Conversely, composites reinforced with linen react negatively to the environment of technical lubricant and aviation fuel.

Opis:
The Early Miocene lacustrine succession of the Ermenek Basin, an intramontane graben in southern Anatolia, consists of hemipelagic, variably calcareous mudstones and pelagic marlstones densely interspersed with tempestite sandstone sheets, subordinate turbidite sandstone sheets and sporadic layers of evaporitic limestone. The marly lake was hydrologically closed and mainly no deeper than 10 m, with the mean fairweather wave base at 1.5 m and storm wave base around 5 m. The deposits abound in trace fossils, including Vagorichnus cf. anyao (its second recognized occurrence), endichnial ferruginous ribbons, large tubular structures, oblique cylinders, small discontinuous ridges, undulating ridges, planar wall structures and a range of other bioturbational features. The tempestites and turbidites show both pre-and post-event trace fossils, with recognizable mixed and transitional layers similar as reported from marine tempestites and turbidites. The trace fossils constitute an impoverished Mermia ichnofacies indicating a considerable environmental stress. The lake salinity fluctuated, and the stress factor is attributed to the extreme environmental conditions (increased salinity and unusual water chemistry) caused by episodes of brackishness due to decreases in rainfall and increases in evaporation. Freshwater conditions are indicated by benthic ostracods and mollusc shells in offshore mudstones and by gastropod shells in coastal coal deposits, whereas marly layers contain only the ostracod species Miocyprideis glabra asulcata, implying mesohaline to polyhaline conditions.
