A study of forest ecosystem development
… taking place with time in a relatively simple ecosystem of Pinus radiata D. Don. on skeletal soils and integrades to Yellow-Brown Sands. Every endeavour was made to keep other soil forming factors (and the influence of other factors on the ecosystem) as constant as possible, thus satisfying the …

Belowground Fungal Community Change Associated with Ecosystem Development
… community change associated with long-term ecosystem development. To understand ecosystem development, the organisms responsible for shaping and driving these systems and their relationships with the vegetation and soil factors, it is critical to provide insight into aboveground and …

Chronosequence studies of ecosystem development of Leymus arenarius dunes in Iceland
Sandhólasvæði, sem hér á landi eru einkum melhólar eða mellönd, eru kvik vistkerfi með stöðugu áfoki sands. Sambærileg vistkerfi er að finna um allan heim, frá hásléttum meginlandanna, áraurum til fjörusanda. Þau eru umfangsmikil á Íslandi en hér er að finna yfir 22.000 km2 af sandauðnum, allt frá …

Community and ecosystem analysis of forests recovering from landslide disturbance: White Mountain National Forest, New Hampshire
… disturbance offer many opportunities to study ecosystem processes under extreme conditions. Landslides reset the topographic, microclimatic, parent material and vegetation state factors of ecosystem development. Water, and nutrient resources following landslides are more heterogenously …

Selective accrual and dynamics of proteinaceous compounds during pedogenesis: testing source and sink selection hypotheses
… in whole soil pool during the 4000 years of ecosystem development. Their interaction with soil minerals, therefore, may play a critical role in the long-term sink and selective accumulation of proteinaceous compounds with some degree of the displacement. This was further confirmed by another …

Technology Transfer in Higher Education
… unravel the quintessential role of research and development (R&D) in shaping university outcomes. Beyond the precincts of the university, the ecosystem development further encompasses stakeholders, individuals from higher education communities, and external partners. This extended ecosystem acts …
