Figueroa-Sandoval, B. ., . Flores-Magdaleno, . Dissolved organic matter (DOM) is an important property of lake ecosystems, resulting from the decomposition of organic matter stored in soils and of plankton in the water column. Colored dissolved organic matter (CDOM), the fraction that absorbs ultraviolet (UV) and visible light, is the controlling factor for the optical properties of many surface waters. Little is known about the mechanisms by which DOM and CDOM evolve in lakes formed during glacial retreat. As part of a larger study of the ecosystems in glacial lakes, the present project examined the quality of DOM and CDOM in lakes in SW Greenland. Nine lakes in . Glomus. sp.)

Soil organic matter plays important role in the maintenance and improvement of soil properties. It is a dynamic material and is one of the major sources of nutrient elements for plants. . Abstract: Human health is an integral component of the Arctic ecosystem. Life expectancy in arctic populations has greatly improved over the last 50 years due to a reduction in morbidity and mortalit Objectives. Define: soil organic matter. Explain the role of inherent factors affecting soil organic matter. Explain the five soil organic matter management practices. Explain how soil organic matter relates to soil function.
