Use of chemical markers in Antarctic ecosystem studies of Demaria Mount
Український антарктичний журнал, 2020 Research is devoted to using chemical markers for studying and description of ecosystems. Photosynthetic pigments – carotenoids and chlorophylls, and soil polymers – humic, fulvic acids and their salts, were used as chemical markers. Correlations between

Physiological Effects of Five Different Marine Natural Organic Matters (NOMs) and Three Different Metals (Cu, Pb, Zn) on Early Life Stages of the Blue Mussel (Mytilus galloprovincialis) [PDF]
, 2017 Metals are present in aquatic environments as a result of natural and anthropogenic inputs, and may induce toxicity to organisms. One of the main factors that influence this toxicity in fresh water is natural organic matter (NOM) but all NOMs are not the

Water-Stable Aggregates and Associated Carbon in a Subtropical Rice Soil Under Variable Tillage
Revista Brasileira de Ciência do Solo, 2016 Tillage systems can influence C sequestration by changing aggregate formation and C distribution within the aggregate. This study was undertaken to explore the impact of no-tillage without straw (NT-S) and with straw (NT+S), and moldboard plow without ...
