As technology develops, sound has become an increasingly important way of measuring the health and biodiversity of ecosystems: our forests, soils and oceans all produce their own acoustic signatures. ...
Measuring forest soil carbon flux gives an insight into the health of forest ecosystems and provides feedback on the effects of global warming. ...
FutMon project Delta‐T Profile Probes have been installed at four sites across the U.K. to provide soil moisture data as part of FutMon, an EU Life+ project. The aim of FutMon is to create a Europe‐ wide long term forest monitoring system. ...
Tupek’s research specializes in greenhouse gases, including measuring and modelling of CO2, CH4, N2O (carbon dioxide, methane and nitrous oxide, commonly known as laughing gas) in forests and peat lands and their interface, and modelling carbon capture in European forests, testing widely used soil carbon models with extensive datasets in ...
Variation of canopy properties between different forest types is seldom taken into account in hydrological and climate models, and consideration of variation inside a forest is normally omitted. In this work, three data sets on near surface energy balance terms (incoming shortwave and longwave radiation; air and snow–soil interface ...
Its surrounding hilly landscape is covered with rich brown forest soil. This landscape is, however, prone to soil erosion -in particular, rills develop when soil is weakened by excessive tillage and exposed to intense rainstorms. If not carefully managed, runoff and soil erosion threaten not only the ...

Plot studies were conducted on a jack pine forest with sandy soil and aspen forests with sandy and loam soils to examine the controls of slope aspect, soil texture and fall soil moisture content on near-surface snowmelt runoff and infiltration. It was hypothesized that near-surface runoff would ...
We used a laboratory 15N tracer study with live and gamma irradiated soils to examine the role of land management in abiotic retention of NO3– in three agroecosytems and a forest soil. Nitrogen retention was defined as the quantity of 15N that remained in soil following salt extractions. Land management only affected N retention ...
In the years since, though, it has lost nearly all its forests and much of its topsoil, forcing the country to import more than half of its grain. ...
Rehabilitation and reforestation of disused forest roads and landings can be facilitated by the incorporation of organic matter. ...
Plant root simulator (PRS) probes, a resin membrane technology, are increasingly used to measure soil nutrient availability in agricultural and nonagricultural systems. Like other resin technologies, the charged surface is meant to sorb nutrients until saturation; however, there is evidence that it acts as a dynamic exchanger in soils with low nutrient ...
To study this, we measured net nitrification and ammonification rates and the 15N and 18O of NO3– in soils from a watershed in Camels Hump State Forest, Vermont, known to be sensitive to sampling disturbance. ...
We used repeated sampling of the forest floor to determine if there was a net loss of Ca from organic horizons of Adirondack forest soils between 1930 and 2004. ...
The impacts of plantation forest management on soil C stocks in New Zealand need to be better understood for the purposes of C accounting under the Kyoto Protocol. ...
Precise and accurate estimation of C and N in forest soils is important for monitoring long-term site productivity and C stock changes. Obtaining such estimates remains a major challenge, however, especially because of high natural variability in the forest floor. Although most researchers have used simple random sampling (SRS) for within-plot ...
Understanding the controls on interactions between soluble organic compounds and the solid soil matrix is important in understanding soil organic matter dynamics in general, including specific impacts on pedogenic processes, nutrient bioavailability, and C sequestration. This study investigated the pH-dependent relationship between low-molecular-weight organic ...
Decadal changes in soil exchangeable K+, Ca2+, and Mg2+ concentrations and contents from 1972 to 2004 in eight intensively monitored plots on Walker Branch Watershed were compared with estimates of increments or decrements in vegetation and detritus. The results from these eight plots compared favorably with those from a more extensive set from 24 soil sampling plots sampled in 1972 and 2004. ...
Extracting fungal mRNA from ectomycorrhizas (ECMs) and forest soil samples for monitoring in situ metabolic activities is a significant challenge when studying the role of ECMs in biogeochemical cycles. ...
Ceriporiopsis sp. strain MD-1, isolated from forest soil, produced several extracellular enzymes that decolorized human hair melanin. ...
Abstract In evergreen broad-leaved forests (EBLFs) in Tiantong National Forest Park, Eastern China, we studied the soil chemistry and plant leaf nutrient concentration along a chronosequence of secondary forest succession. Soil total N, P and leaf N, P concentration of the most abundant plant species increased ...
