earthworms and ecological processes

Dr. Yahya Kooch is currently an Associate Professor of soil ecology at Tarbiat Modares University (TMU), Tehran, Iran.
His scientific activities concern soil ecology as well as biogeochemical cycles of carbon and nutients in ecosystems. His main research interests are i) pedodiversity in different land uses/covers, ii) linking soil biota communities with nutrient cycling processes, iii) Influence of soil properties and plant species on N availability, iv) evolution of organic matter in soils and sediments in relation to climate changes (sinks or sources of C?), and v) diversity of humus forms in terrestrial ecosystems.

Prof. Dr. Yakov Kuzyakov is currently a Professor of soil sciences at Georg-August-University of Göttingen, Germany.
His main research interests are in the fields of soil biogeochemistry, C and N turnover in the rhizosphere and other hotspots including drilosphere, and application of isotopes in ecosystem sciences. His expertise is soil ecology, biogeochemistry, rhizosphere ecology, soil degradation, C and N cycles, C sequestration, priming effects, nutrient mobilization, rhizodeposition, pedogenic carbonates, partitioning of CO2 fluxes, land use, low molecular weight organic substances, agroecology. stable and radioactive isotopes ’applications: labeling, natural abundance, isotope dilution, imaging.
