Next began the muskegs, which almost entirely stood under water; these we had to cross for miles; think with what misery, every step up to our knees. . . . The whole of this land of the Lapps was mostly muskeg, here called stygx. A priest could never so describe hell, because it is no more horrible. Never have poets been able to picture the Styx so foul, since that is no fouler.—CAROLUS LINNAEU...

abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...

this experiment was designed to characterize the effects of size and concentration of an iranian clinoptilolite zeolite on the growth officus benjamina (starlight) in peat base media. ficus benjamina was stock rooted and grown in a peat consisting perlite (2: 1 v/v) (p: pe), zeolite (10, 20, 30 and 40 v/v %, two sizes 0.5-3 mm and 3-8 mm) instead of peat in p: pe (2: 1 v/v) media. ficus benjami...

Studies of the properties of soil organic matter are essential for understanding the humification reactions and soil diagenesis processes. The aim of this study is to analyse properties of peat and peat humic acids as well as factors influencing their variability. Humic acids isolated from an ombrotrophic bog peat profile were used as study objects. Relations among peat age, decomposition and h...

Vegetation analysis in ten central Florida cypress (Taxodium distichurn) swamps was undertaken to determ•ne the response of woody species composition to clearcutting. Line transects hrough swamps that had been harvested by clearcutting within the last 5 years demonstrated that all but one of these swamps are likely to recover their original species composition and a normal stem density. Cypress...

Experimental research involving Arabidopsis thaliana often involves the quantification of phenotypic traits during cultivation on compost or other growing media. Many commercially-available growing media contain peat, but peat extraction is not sustainable due to its very slow rate of formation. Moreover, peat extraction reduces peatland biodiversity and releases stored carbon and methane into ...

The sensitivity of Earth’s wetlands to observed shifts in global precipitation and temperature patterns and their ability to produce large quantities of methane gas are key global change questions. We present a microwave satellite-based approach for mapping fractional surface water (FW) globally at 25-km resolution. The approach employs a land cover-supported, atmospherically-corrected dynamic ...

Although the environmental mycobacteria are slow growing relative to other microorganisms in water and soil which would suggest that they are poor competitors, compensating factors permit survival, growth and persistence in natural and human-engineered environments. Factors such as the hydrophobic, lipidrich impermeable envelope, biofilm formation, acid resistance, anaerobic survival and metabo...

hydrocarbons (PAHs) in coastal marine sediments: case studies in Cotonou (Benin) and Aquitaine (France) areas. Marine Pollution Bulletin 40, 387–396. Steinhauer, M.S., Boehm, P.D., 1992. The composition and distribution of saturated and aromatic hydrocarbons in near shore sediments, river sediments, and coastal peat of Alaskan Beaufort Sea: implications for detecting anthropogenic hydrocarbon i...

The Poço das Antas National Biological Reserve is located in Rio de Janeiro State, southeast Brazil. This paper presents information on past environmental characteristics of the area through pollen analysis. Two sedimentary columns were collected and five samples were selected for radiocarbon dating. The following ages of the columns from bottom to top were detected: column 1 - 1.20-1.16 m: 608...
