Fate of natural and anthropogenic particles in peat bogs
… fate of anthropogenic and natural particles in peat bogs, to see which geochemical processes can affect the suitability and accuracy of peat bogs as archives of atmospheric deposition, and also the effects of these inputs on the bog ecosystem. To test whether peat bogs are accurate archives of …

Determination of Arsenic and Arsenic Species in Ombrotrophic Peat Bogs from Finland
… arsenic (As) has been preserved in ombrotrophic peat bogs from Finland. The changing rates of atmospheric As deposition have been reconstructed using peat cores from three Finnish bogs: Harjavalta (Har), nearby a Copper (Cu) - Nickel (Ni) smelter, Outokumpu (Out), near a famous Cu-Ni mine, and a …

Disturbance in Small, Fragmented Peat Bogs and its Contribution to Iris pseudacorus Colonisation
Peat bogs are of global importance as carbon sinks and hotspots of biodiversity. In British Columbia, some peat bogs such as the Galiano Island Ecological Reserve are fragmented by the construction of roadways (Cook Road). This construction impacts the dynamic of the bog, which is also affected by …

Stormy records from peat bogs in south-west Sweden : implications for regional climatic variability and vegetation changes during the past 6500 years
… during the past 6500 years. Two ombrotrophic bogs, Store Mosse and Undarsmosse, situated on the coastal plain of Halland, were selected for this purpose. The coastal plain of Halland is positioned in the cyclone path and is therefore particularly sensitive to changing cyclone frequencies and …

Holocene vegetation and palaeoenvironments of the Southern Cederberg mountains of South Africa : palynological evidence from fossil hyrax (Procavia) dung middens
… in humid regions as polled traps (swamps and peat bogs) there are usually abundant. However arid and semi-arid regions (such as southern Africa) lack fossil pollen because of the scarcity of pollen preserving bodies. This attribute results in difficulties in palynological studies regarding the …

Application of the peat archive as tool in environmental chemistry
Ombrotrophic peat bogs are natural archives of atmospheric deposition of pollutants. Therefore, peat profiles can be used to study the chronology of environmental contamination with harmful pollutants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and per- and …

Hochmoore im Erzgebirge - Untersuchungen zum Zustand und Stoffaustragsverhalten unterschiedlich degradierter Flächen
Die Hochmoore des Erzgebirges sind auf Grund ihrer jahrhunderte langen Nutzung und der ökosystemaren Wandelprozesse der vergangenen 10 - 15 Jahre unterschiedlich stark degradiert. Gleichzeitig sind sie durch den Austrag vergleichsweise hoher Austräge von DOC (Dissoloved Organic Carbon) …

Mineralogical, Chemical, and Isotopic (Sr, Pb) Composition of Atmospheric Mineral Dusts in an Ombrotrophic Peat Bog, Southern South America
Peat bogs are excellent environmental archives of atmospheric deposition of many major and trace elements and of mineral dusts. Geochemical studies of major and trace elements, mineralogy of atmospheric dust and their radiogenic isotope compositions in the peat, provide important information about …

Etude de la colonisation des milieux tourbeux du Plateau de Saint-Hubert (Belgique) par les macroinvertébrés aquatiques
Les milieux tourbeux sont des habitats semi-naturels qui ont été fortement affectés par la fragmentation. Actuellement, de larges projets de restauration visent à recréer ces milieux. Des indicateurs de suivi sont dès lors nécessaires pour évaluer la réponse post-restauration des espèces à ces …
