Przedstawiono problem zróżnicowania gatunkowego na obszarze o różnej intensywności antro-pogenicznej w czasie i przestrzeni. Główne źródła antropopresji pochodzą z obszarów przyległych do analizowanego. Zmiany antropogeniczne obejmują tu głównie stosunki wodne, wydeptywanie i utwardzenie gleby oraz zanieczyszcze-nie środowiska. W takich warunkach formowały się różne typy siedlisk, które zostały skolonizowanie przez różne eko-logicznie i geograficznie grupy roślin o zróżnicowanych wymaganiach siedliskowych. Na obszarze tym stwierdzono wy-stępowanie 149 gatunków roślin naczyniowych. Badana flora składa się z gatunków leśnych, muraw kserotermicznych, apofitów, antropofitów oraz z gatunków o szerokiej amplitudzie ekologicznej. Większość gatunków jest związana ze zbiorowiskami muraw kserotermicznych. Wyniki badań wskazują, iż w niektórych przypadkach wpływ antropopresji doprowadził do wzbogacenia gatunkowego na terenach o wyższej intensywności ludzkich działań

The study presents results of investigations on relations between associations of carpological remains of aquatic plants preserved in the roof layer (2 cm) of deposits and the contemporary vegetation of small shallow reservoir. Carried out analy-ses of 40 samples of capacity of about 100 cm3 proved that associations of macrofossils generally well reflect the species com-position of parent phytocenoses. In deposits 60% of presently occurring species were represented. It was also stated that among many factors influencing the distribution of diaspores of aquatic plants in the environment investigated both distribution of patches of emerged vegetation and shape of its bowl are of crucial importance

Presented in this paper are the results of studies on the species of fauna (amphibians and birds) of two groups of aquatic reservoirs which have formed in subsidence depressions. The studied reservoirs are located in one of those areas in Europe which were most transformed by mining, an area located in southern Poland. Studies have shown that groups of water reservoirs in subsidence depressions are, on a regional scale, important places where amphibians and birds reproduce; for birds, this is also where they feed and rest. On land where there were previously no natural lakes, such reservoirs may also function as important centres of biodiversity and refugees for rare species of animals. The results of this paper indicate that reservoirs which came into existence as a result of underground mining can have great importance for the improvement of the environment on lands disfigured by mining and should be a subject of interest for environmental engineering.

The analysis of n-alkanes in palaeoenvironmental studies of peatlands is mainly limited to ombrogenous peatlands which are a rare feature in the environment. Using n-alkane and plant macrofossil analysis, we have tracked changes in the environment in the valley of a large Central European river. We tested the possibilities for applying such studies to low-moor bogs which are the most commonly occurring type of bog in the world. Representative peat samples were taken from two profiles in a peatland located in the Vistula Valley (southern Poland), and they were analysed for the occurrence and distribution of biomarkers. The distribution of n-alkanes was determined using gas chromatography-mass spectrometry (GC–MS). The botanical composition of the samples was determined by analysis of plant macrofossil remains, and the degree of peat decomposition was also determined. Samples of low-moor peat were characterised by a prevalence of medium- and long-chain n-alkane homologues, which is ty...

Банашек Я., Шимчик А. Влияние антропогенной деятельности на дифференциацию растительных видов на примере территории охраняемого ландшафта. Представлена проблема видового разнообразия на территории, отличающейся разной нитенсивностью антропогенного прессинга в пространстве и во времени. Основной источник данного прессинга связан с территорией, прилегающей к анализируемой. Антропогенные изменения проявляются здесь, в основном, в водных отношениях, в виде вытаптывания и уплотнения почвы, а также в загрязнении среды. В данных условиях формировались разные типы биотопов, в дальнейшем освоенных экологически и географически разными группами растений с дифференцированными биотопными требованиями. Нa данной территории выявлено наличие 149 видов сосудистых растений. Исследуемая флора состоит из видов: лесных, травянистых ксеротермических, aпофитов, антропофитов, а также видов с широкой экологической амплитудой. Большинство видов связаны с ксеротермическими травянистыми сообществами. Выявлено,...

Summary. The objective of this paper was an attempt at defining the plant diversity and present-ing the participation of protected, rare and endangered species in associations or communitieswhich are formed in the explored quarries (Pogoria I, Siemonia, Ku źnica War ezynska and MaczkiBor). In the parts of quarries which were not reclaimed, unique biocenotic systems are created dur-ing succession. These systems are biotopes of numerous rare and protected plant species, includingthose described in Polish Plant Red Data Book: Pinguicula vulgaris, Liparis loeselii and Malaxismonophyllos. The most abundant in populations of rare species are communities from Cariciondavallianae and Caricion nigrae compound . The conducted research has shown that quarries maybe a suitable place for survival and development of a wide range of rare and critically endangeredPolish plant species.Key words: sand quarry, rare and protected species, biodiversity, Silesian Upland INTRODUCTION Relatively shallow lo...

On the basis of the analysis and interpretation of maps, published literature, and environmental reconnaissance, this article discusses environmental transformations in the area of the Kuźnica Warężyńska sand mine in southern Poland over the years 1944–2015. A comprehensive ecological analysis was carried out concerning spatial development, mining activity, hydrogeological and hydrological conditions as well as the biotic environment. Among the unfavourable changes found were a drastic reduction in the agricultural function of the area (from 7.03 to 0.47 km2), mainly due to periodic activity of sand mine in 1967–2002, covering an area of about 5.80 km2, the destruction of the original biocenoses, the depletion and deterioration in quality of the groundwater resources, and man-made transformations of the hydrographic network (during the mine’s activity its length reached over 103 km). Vegetation changes during the 70-year period examined were closely related to human mining activity....

Peat sediments represent important environmental and climatic archives, as well as recording information on the processes affecting the formation of these deposits; combined these data can be used for paleoreconstruction of peat-bogs. In this paper we characterize heavy mineral-rich sandy layers from two peat-bog sites in Mizerów and Strumień (Poland). In both cases, the most common identified mineral suite is: epidote, staurolite, tourmaline (dravite and schörl), garnet, spinel, Al2SiO5 polymorphs (sillimanite, kyanite, andalusite), amphibole (mainly hornblende), pyroxene (e.g., richterite, diopside), perovskite, topaz, cordierite, apatite, monazite, chromite, ilmenite, chlorite, iron oxides, rutile and siderite. This mineral suite is characteristic of a metamorphic aureole surrounding a magmatic body. Pyrite is likely authigenic in origin. Apatite and monazite were employed for U-Pb and CHIME dating, respectively. Based on the U-Pb age information composition and textural features...

The environmental variability during the Mazovian/Holsteinian interglacial is better understood thanks to the results of multidisciplinary palaeobotanical studies. The perfectly preserved and abundant material from Nowiny Żukowskie in SE Poland has been the subject of numerous palaeobotanical analyses. The results both of initial pollen analysis and of the examination of plant macroremains provide a detailed view of changes in the palaeoenvironment of this area during the Mazovian/Holsteinian interglacial. Originally, the water basin was mostly the habitat of plants indicative of low trophy. The frequent occurence of swamp plants evidences a change in hydrological and climatic conditions consistent with the intra-interglacial climatic oscillation. In the subsequent part of the optimum, an expansion of swamps with Aracites interglacialis and Dulichium arundinaceum was recorded. The development of a peat bog overgrown by i.a. Sphagnum sp., Eriophorum vaginatum, and Andromeda polifolia...

This paper describes specimens of Pediastrum argentinense-type in Late Quaternary sediments, focusing on their morphological variability and stressing their value for palaeobotanical studies. Although the taxon strongly resembles P. argentinense Bourrelly et Tell in Tell, known only from South America, some morphological differences between P. argentinense and P. argentinense-type lead to the conclusion that we are dealing with a separate taxon provisionally named P. argentinense-type. To make its taxonomic position clear, there is a need for detailed morphological observations of living specimens and molecular analyses. This taxon was found in sections spanning the entire Late Glacial and Holocene periods across Central Europe. Its affinity to sediments originating in shallow and strongly overgrown water bodies makes it a good indicator of such conditions in past environments.

Ekologia (Bratislava), Vol. 32, No. 4, p. 388-395, 2013.The aim of study is a presentation of main vegetation landscape diversity and biodiversity in case of endemic species in the Fann Mountains area, in horizontal and vertical approach. In terms of biodiversity, the high-mountain ecosystems of Central Asia include the most valuable areas in the world called as hotspot, and also are exposed to intense human pressure causing the destruction of habitats. Vegetation landscapes of Fann Mountains are very diverse because of high-mountain character of this area, local climatic conditions, topography and habitats. That differentiation leads up to biodiversity and formation of unique plant landscapes and endemic species. The vegetation landscapes in altitude order are represented by forbs meadow steppe, thymes, swamp, broad-leaf fore...
