Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
Gonystylus bancanus (Miquel) Kurz is one of the most valuable timber species in tropical peat swamp forest. Its timber is widely used for furniture, decorative cabinets and interior decoration. Due t...
New research published this week in the journal Nature Geoscience, co-authored by Adam Watts, a fire ecologist at Nevada’s Desert Research Institute (DRI) and deputy director of DRI’s Climate, Ecosyst...
Environmental concerns raised the demand for alternative growing media substituting Sphagnum peat. However growing media formulations still depend on peat and alternatives are limited. Biochar is carb...
A method that could be used to detect the change of the environment was used to determine the input of trace elements from the atmospheric fallouts into the biosphere near Tomsk city (West Siberia, Ru...
New burned area datasets and top-down constraints from atmospheric concentration measurements of pyrogenic gases have decreased the large uncertainty in fire emissions estimates. However, significant ...
Several processes may contribute to systematic downcore trends in δ13C of bulk Sphagnum peat. Whereas changes in water availability during C assimilation may change δ13C values in both a negative and ...
Peatlands play an important role in the global carbon cycle and represent both an important stock of soil carbon and a substantial natural source of relevant greenhouse gases like CO2 and CH4. While i...
Most studies of peat hydrology have concentrated on processes below the watertable where pore water pressures and hydraulic conductivity are measured using piezometers. While piezometer head recover...
Since peat soil differs from mineral soil in several respects, mineral-soil calibration functions for time domain reflectometry (TDR) are not necessarily applicable. This paper evaluates a number of...
Estonia is rich in peatlands, which cover 22.3% of its territory. About 1/4 of them are under protection, ~ 2% have been assigned for peat production, and ~ 1% is abandoned. Several peatlands are drai...
In a field experiment to investigate potential impacts of climatic change, a small area of flush wetland in Wales was subjected to three successive years of simulated summer drought/rewetting (autumn...
A simple method for the installation of groundwater lysimeters in peat soils was developed which reduces both time and financial effort significantly. The method was applied on several sites in the Rh...
Smoke-haze episodes caused by vegetation and peat fires affect parts of Indonesia every year with significant impacts on human health and climate. Particularly fires in degenerated peat areas release ...
A field manipulation study was established to demonstrate effects of simulated wet N and S deposition on a young (planted 1986) stand of Sitka spruce growing on a predominantly organic soil in an area...
