Population Numbers

This research, carried out in the years 2011–2013, aimed to evaluate <em>Salix lapponum</em> stands in the peat bogs of Polesie Lubelskie Region as well as to determine the condition of the population and the changes that have taken place since the 1950’s. An inventory carried out in 25 stands of <em>S. lapponum </em>known from the literature shows that the number of its stands has decreased by 80% in Polesie Lubelskie Region. In all the confirmed locations, a decrease in population numbers was also found in relation to the data known from the literature since the 1950’s. In the majority of the population locations that were considered to be extinct, there were no significant changes in habitat conditions, and ecological succession and changes in hydrological conditions could have been the cause of habitat changes only at a few sites. In the light of the study, the preservation of the <em>S. lapponum </em>population in Polesie Lubelskie seems to be impossible if appropriate active conservation measures are not taken immediately. Because area-based conservation, which covers most of the habitats of the studied species, does not bring the expected results, the possibility of <em>ex situ</em> conservation and enlargement of the populations existing in the natural environment in peat bog ecosystems in Polesie should be explored.

Salix Lapponum

Studies carried out in 2001-2003 were aimed at evaluation of the current structure and conditions of the population along with the recording of biometric traits of downy willow specimens at their natural stand on Lake Bikcze. It has been found that the population of downy willow on the peat bog near Lake Bikcze has much increased since the 1950's. The character of phytocoenoses, where <i>Salix lapponum</i> occurred most abundantly, may prove its wide requirements in terms of habitat conditions. <i>S. lapponum</i> specimens were in good condition. Furthermore, blooming of male and female specimens as well as great viability of pollen grains was recorded. High variability of selected biometric traits for studied species' specimens was found.

This paper presents the results of a pilot field study, conducted in July 2007, designed to make floristic evaluation of the peat bog area adjacent to the western shore of Lake Bikcze (Łęczyńsko-Włodawskie Lakeland). The main aim of the study was to confirm the occurrence of populations of rare and legally protected plant species in this area and to identify, on a preliminary basis, habitat conditions in their stands. The occurrence of populations of the following strictly protected plant species: <i>Betula humilis</i>, <i>Salix lapponum</i>, <i>Salix myrtilloides</i>, <i>Carex limosa</i>, <i>Drosera intermedia</i>, <i>Drosera rotundifolia</i>, <i>Dactylorhiza incarnata</i>; and partially protected species: <i>Menyanthes trifoliata</i>, has been confirmed in the studied peat bog. Both an investigation of abiotic factors, conducted <i>in situ</i>, and an analysis of the species composition of the flora in terms of habitat preferences of particular groups of taxa have shown that the described rare plant species find suitable conditions for their growth and development in the studied peat bog.

The metal content was determined using the WD-XRF method in the peat from the Wąpiersk bog and the Las Nadwelski bog (Welski Landscape Park, Poland). The results of the study show that the concentration of metals, especially heavy metals in peat bogs in Welski Landscape Park is low in general. In both bogs, the concentration of heavy metals was lower in the center than on the border. This shows that heavy metals are absorbed by the peat at the border and their further migration is limited. There are more elements such as iron, calcium and magnesium in the Las Nadwelski bog. There is more light on the border of the forest, which also plays an important role in decomposing plant debris, releasing metals. Heavy metals content was higher in Wąpiersk bog – a bog with higher anthropopressure. To sum up, the peat bog actively captures heavy metals, immobilizing them, and acts as a kind of “filter”. Peat is a good agent for retrospective monitoring of metals migration and accumulation in the environment.

Transformation of Lake Ecosystem into Peat Bog and Vegetation History Based on Durne Bagno Mire (Lublin Polesie, E Poland)In this paper, the history of Durne Bagno, i.e. the largest peat bog in the Lublin Polesie, is shown. Peat bogs are a unique element of the Polesie landscape. They occur mostly in the subregion of the Łęczna-Włodawa Lake District occupying 1.07% of its area. They fill basin-shaped depressions without outflow, often in the immediate vicinity of dystrophic lakes. Based on interdisciplinary research, the changes of vegetation cover and the Durne Bagno lake-mire ecosystem in the Late Glacial and Holocene are presented. The environmental conditions are reconstructed from pollen analysis, detailed identification of algae ofPediastrumgenus and chemical composition of deposits, together with the results of Cladocera analysis. The distribution of archaeological artefacts in the surroundings of Durne Bagno peat bog gives the view on the intensity of settlement in this area. The duration of the limnic and mire stages during the development of the ecosystem was different in different parts of the examined depression. In its central part the limnic stage lasted about 8000 years and included the period from the Late Glacial to the middle Holocene (to about 6000 BP). It is represented by 7 pollen zones and 6 chemical zones. The mire stage contained a part the Atlantic period and on the Subboreal and Subatlantic periods. It is represented by 4 pollen zones and 5 chemical zones. Limnic and mire deposits differ widely in the concentrations of chemical elements. The contents of mineral material and almost all analyzed elements in limnic deposits are high. These deposits are characterized by positive correlation between the contents of Zn and Cr and the frequency of Cladocera fauna. Peat contains very low amount of mineral material. The contents of Ca, Sr and Ba are rather high in sedgemoss peat. The concentrations of these elements decrease upwards due to oligotrophic processes and sedentation of sedge-Eriophorum-Sphagnumpeat. Peat succession was modified by pastoral economy of prehistoric man.

We used moss increment counting to obtain well-defined samples of the topmost peat layers of two Sphagnum fuscum hummocks. The two ombrotrophic bogs, Lakkasuo in central Finland and Korvinsuo in eastern Finland, are of different ages, covering 3 and 9 ka, respectively. Using AMS dating, we traced bomb-produced 14C through the topmost parts of the two peat profiles. A well-defined 14C activity peak was found in both sequences dating the corresponding layer to ad 1965. A comparison between the maximum peat activities and the corresponding atmospheric values for the period of interest provides an opportunity to evaluate the amount of CO2 emanating from the decaying peat bog, and taken up by the living sphagnum plants.Considerable variations in δ13C values were also observed. These variations indicate, at least partly, annual variations in the emission rate of CO2 from decomposition of older peat in the bog, and are connected with climatic factors such as temperature and precipitation.

ABSTRACT Semi aquatic Heteroptera species from some mountainous tributaries of the Vişeu River were collected and their relations with habitat variables were investigated. Only two species, Gerris lacustris and Gerris costae were found, either one or both species, in almost half of the investigated sampling stations. Correlation analysis between samplings and habitat conditions showed that Gerris lacustris prefers small deep ponds or river banks with steep slopes and is easily adaptable to habitat changes, while Gerris costae is mostly found in large marshes with low, stagnant water and high amounts of vegetation. Both species are relatively tolerant to human impact in their habitat, Gerris lacustris more so. The two species are negatively correlated to each other, as an expression of competition between them. Principal Component Analysis resulted in two dominant factors explaining almost 60% of the habitat variation, and their graphic representation proved the observed correlations.
