Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Small‐Scale Topographic Variability Shapes Molecular Diversity of Organic Matter in Coastal Dune Soils

Journal of Plant Nutrition and Soil Science, EarlyView.
Topography shapes ecosystem controls, driving microclimate, hydrology, and vegetation, which, in turn, influence topsoil traits and DOM composition in coastal dune soils. Distinct molecular patterns emerge across north‐facing and south‐facing slopes and dune valleys.

Effects of shading on relative competitive advantage of three species of Sphagnum [PDF]

Mires and Peat, 2015
(1) Sphagnum is an important genus of bryophytes holding 10–15 % of the terrestrial carbon stock. With climate change a drier surface may increase the abundance of vascular plants on peatlands, so shading of Sphagnum may increase. Here we describe growth

Estimation of water erosion threat of the Smuga stream basin in the Beskid Wyspowy / Ocena zagrożenia erozją wodną zlewni potoku Smuga w Beskidzie Wyspowym

Environmental Protection and Natural Resources, 2013
In this work, results of evaluation of potential water erosion threat of the Smuga stream basin in Beskid Wyspowy were presented according to the USLE model and the GIS techniques. The basin area is 5.40 km2; mean height is 636.4 m a.s.l.

The Existence Value of Peat Swamp Forest in Peninsular Malaysia [PDF]

Forests form the dominant natural ecosystem in Malaysia. About 55% of Malaysian land area is forested and endows a rich diversity of flora and fauna. Peat swamp forests constitute a significant component of forest and account for about 75% of the country’

Temporal Dynamics of Soil Organic Carbon Contents in Long‐Term Monitored Arable Sites in Lower Saxony, Germany

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Temporal changes in soil organic carbon (SOC) contents in agricultural soils are variable, and underlying drivers are not sufficiently understood. Aim The objectives were to describe the long‐term dynamics of SOC contents at 41 sites in Lower Saxony, Germany, and to analyze the relationships between estimated long‐term changes of ...

Valuation of natural assets of some raised peat bogs against a background of Bieszczady Mts. landscape of the Lutowiska district

Environmental Protection and Natural Resources, 2014
Na terenie „Krainy dolin” w Bieszczadach Zachodnich zachodzą obecnie niekorzystne zmiany sukcesyjne polegające między innymi na wymieraniu cennych gatunków roślin, a niekiedy nawet całych zespołów roślinnych oraz zanik mozaikowego układu biocenotycznego.

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.
