Opis:
The Lower Jurassic Ciechocinek Formation from the Czestochowa-Wielun region of SW Poland comprises greenish-grey muds and silts as well as poorly consolidated mudstones and siltstones with lenticular intercalations of fine-grained sands, sandstones and siderites. Analysis of a mineral composition indicates that the detrital material was derived mainly from the weathering of metamorphic and sedimentary rocks of the eastern Sudetes with their foreland and of the Upper Silesia area, and that this material underwent repeated redeposition. The Fe-rich chlorites which give the green colour to the mudstones of the Ciechocinek Formation are most probably early diagenetic minerals, genetically linked with the deposition in a brackish sedimentary basin.

Opis:
The paper presents a list of the rarest endangered segetal weeds recorded in the Silesian Upland during the previous two decades (1989-2009) with threat categories as well as their distribution concentration map. In the area researched, fifty red-listed taxa (i.e. species, subspecies, and forma) considered to be endangered on a regional and/or national scale were recorded. Thirty-five of them constitute the group of the rarest species (up to 20 localities in the studied area). Lythrum hyssopifolia (included in the Polish Red Data Book of Plants), Adonis aestivalis, Anagallis foemina, A. arvensis fo. azurea, Filago arvensis, Fumaria parviflora, F. rostellata, F. schleicheri, Kickxia elatine, Misopates orontium, Saxifraga tridacylites are among the most interesting segetal weed species noted in the study area. Archaeophytes are the most dominant; however, there is also a remarkable group of apophytes. One species, i.e. Portulaca oleracea is a_kenophyte, while Fumaria parviflora has the status of an ephemerophyte in Polish flora. In the northern part of the Silesian Upland (mesoregions the Tarnowskie Góry Ridge and the Chełm) and in the north-eastern part (the Jaworzno Hills) the concentration of the analyzed species localities corresponds to the presence of calcium-rich rendzina soils as well as to the traditional agricultural methods still commonly applied in that area. A decrease in the number of stands of a vast majority of calcicolous weeds including the character species of the Caucalidion lappulae alliance was observed. Moreover, the analysis of relationship between some environmental factors and the endangered species by using CCA was tested...

Opis:
Sideritic rocks, which are characteristic constituents of muddy-silty deposits of the Lower Jurassic Ciechocinek Formation, occur commonly as layers, lenses and small irregular concretions composed of siderite mudstone and siltstone as well as less common lenses of sideritic sandstones. Three types of siderite cement were observed in thin sections: fine-crystalline variety (SF), coarse-crystalline rhombohedra (SR) and fine-crystalline biogenic aggre gates (SA). In all these types BSE analysis revealed compositional zonation of crystals, with in ternal parts enriched in Mg, Mn and Ca and outer zones almost pure siderite. d13C values and chemical composition of siderites combined with the presence of early diagenetic pyrite indicate that siderite crystallized from brackish marine-derived solutions; only in the case of two samples from the lower part of the Ciechocinek Formation the fresh water origin cannotbe excluded. Mn and Fe were supplied by rivers and released by Fe- and Mn-reduction in suboxic zone, whereas Mg and Ca were derived from sea water, which infiltrated into the sediment. Crystal zonation resulted from the diagenetic evolution of pore water as the sediment was buried. Similar composition and development of siderite crystals from different parts of one layer indicate that siderite precipitated simultaneously throughout the whole horizon. Precipitation began from the formation of numerous nuclei and continued by growth of crystals onto them. It could begin already in the iron reduction subzone and continued in the sulphate reduction and methanogenesis zones.

Opis:
The purpose of this paper is to present the role of the selected species (i.e. associations character species, endangered as well as the most expansive weeds) in arable field communities in the area_of the Tarnowskie Góry Ridge and the Chełm, two mesoregions of the Silesian Upland (southern Poland). On the basis of 750 phytosociological relevés taken using the method of Braun-Blanquet (Braun-Blanquet 1964) between 1995 and 2009, eight weed associations as well as numerous rump communities were distinguished. Phytocoenoses without a significant contribution of the association character species comprised about 68% of the patches analysed in the cereal crop and about 12% of the communities established in the root plant crop. Very often the character species of cereal weed associations occurred sporadically or in small numbers. Some expansive weeds (e.g. Apera_spica-venti (L.) P. Beauv., Avena_fatua_L., A. vilis Wallr., Chenopodium album L., Echinochloa_crus-galli (L.) P. Beauv., Elymus repens L., Galinsoga_ciliata_(Raf.) S. F. Blake, G. parviflora_Cav.) played an important role in the communities analysed. The vanishing of some weed species and the spread of others has resulted in the transformation of the composition and structure of the segetal communities. a_vast majority of rare and endangered weed species in the studied area_are considered to be very sensitive to modern agriculture methods, e.g. chemicalization, introduction of new crop cultivars, effective cleaning of seed materials, drainage etc. (Siciński 1998; Warcholińska_1998)...

Opis:
The investigation of Ambrosia pollen counts in the air of Sosnowiec was carried out from 1998 to 2010 by means of the volumetric method. The pollen season which was determined by means of the 98% method started at the end of July and the beginning of August and lasted until the end of October. The highest Ambrosia pollen count was recorded in 1999 (222 grains x m-3) and the lowest in 2001 (18 grains x m-3). It was stated that the daily count of pollen grains depended on the wind direction and maximum air temperature. The strongest correlations were found with maximum temperature and with a wind direction from the south east. A high negative correlation coefficient was found between the frequency of inflows of air masses from the west and the annual total of pollen grains and the value of the maximum daily count. The closest sites of Ambrosia L. are at a distance of 25–40 kilometres from the sampling point. Significant correlations with the frequency of inflow of air masses can support the conclusion that Ambrosia pollen grains recorded in Sosnowiec were most probably carried not only from local sources but also, at least in part, from distant places.
Badania koncentracji pyłku Ambrosia w powietrzu Sosnowca prowadzono w latach 1998-2010 metodą wolumetryczną. Początek sezonu pyłkowego Ambrosia, wyznaczony metodą 98%, rozpoczynał się na przełomie lipca i sierpnia i trwał do końca października. Wysokie koncentracje pyłku notowano najczęściej w trzeciej dekadzie sierpnia lub w pierwszej połowie września. Najwyższe stężenie pyłku Ambrosia odnotowano w 1999 roku (222 ziarn x m-3), najniższe w 2001 roku (18 ziarn x m-3). Wykazano, iż stężenie dobowe ziarn pyłku zależało od kierunku wiatru i temperatury maksymalnej powietrza. Najsilniejszą korelację stwierdzono dla temperatury maksymalnej i dla kierunku wiatru z południowego wschodu. Znaleziono wysoki ujemny współczynnik korelacji między częstością napływu mas powietrza z zachodu a wartością sumy rocznej ziarn pyłku oraz z wartością maksymalnego stężenia. Stwierdzono również oddziaływanie masy powietrza polarno-morskiego na długość sezonów pyłkowych i na wartości maksymalnego stężenia Ambrosia. Przy napływie tego typu powietrza notowano dłuższe sezony pyłkowe oraz niższe maksima sezonowe. Stanowiska z Ambrosia zostały stwierdzone w odległości 25-40 km na SW i NW od punktu pomiarowego. Istotne korelacje z częstością napływu mas powietrza mogą potwierdzać fakt, iż ziarna pyłku Ambrosia rejestrowane w Sosnowcu pochodzą nie tylko z lokalnych źródeł ale również z dalekiego transportu.

Opis:
The Błędów Desert is situated in the south of Poland. In this area, sand-gravel sediments predominate. The origin of the Błędów Desert is not associated with climatic conditions but with a strong development of excavation industry which started in the region in the Middle Ages. The surrounding forests became the main fuel source for the development of mining and metallurgical industry. Therefore, the area of the Błędów Desert was completely deforested. The paper presents reasons for the acceleration of biocenotical systems in the investigation area. For this purpose, transects representative for the following stages of plants successions: stage of encroachment plants, stage of sodding, stage of bushes (shrubs), stage of biogroup and stage of afforestation were made. Plant succession in the investigated transects developed in a multidirectional way. The ground for plants settling in the Błędów Desert represents fluvoiglacial, fluvial and aeolian sand with various grain sizes. Locally, in the old deflation fields, relict horizons of older podzolic and rust-coloured soil are the ground for the invading plants. The process of plant and soil succession takes place at the same time. Content of the available mineral elements in the initial horizons is different; it depends on the plant species in the places where these horizons developed.
