Editorial: Peatlands - Paleoenvironments and carbon dynamics

Power laws governing hydrology and carbon dynamics in northern peatlands

Environmental and biological variables fluctuate over different time scales. On the basis of power spectral analysis of 14 time series at four sites from northern peatlands (fens and raised bogs), the temporal variability of physical environment (temperatures, water tables) and biological variables (CO2 flux) shows power-law behaviour, with a scaling exponent ranging from about 0.5 to 1.5. The ...

Africa from MIS 6–2: Population Dynamics and Paleoenvironments

T volume includes papers from a conference held at the McDonald Institute for Archaeological Research in 2010. The aim of the conference was to examine the histories of populations on the African continent through the use of a variety of data sets—archaeology, genetics, paleoenvironments, and paleontology—to reach a more nuanced understanding of hominin skeletal and behavioral evolution, how po...

Impacts of restoration of forestry-drained peatlands on nutrient and organic carbon exports and methane dynamics

PEATBOG: a biogeochemical model for analyzing coupled carbon and nitrogen dynamics in northern peatlands

Elevated nitrogen deposition and climate change alter the vegetation communities and carbon (C) and nitrogen (N) cycling in peatlands. To address this issue we developed a new process-oriented biogeochemical model (PEATBOG) for analyzing coupled carbon and nitrogen dynamics in northern peatlands. The model consists of four submodels, which simulate: (1) daily water table depth and depth profile...
