  Title: Effects of repeated exposure with strong static magnetic fields of MRI on reproduction and development in an animal model
  Description: The COEVOLVE project asks the question: How did the Earth's system co-evolve with human activities over the Holocene? During the 12,000 years preceding the Industrial Revolution, melting ice sheets, stabilizing sea level, and changes in temperature and precipitation patterns influenced global vegetation and soil properties. Over the same time period, humans adopted agriculture, domesticated animals, developed metallurgy and other technologies, and evolved in their social and cultural systems. These changes led to exponential growth in human populations, urbanization, and migration. Human and natural environmental change over the Holocene resulted in the transformation of the Earth's system by modifying land cover and through emissions of greenhouse gases and aerosols. A growing body of research has attempted to evaluate the importance of past human-environment interactions for the present and future behavior of the Earth system, including climate change and sustainability of ecosystems. Many of these studies draw starkly differing conclusions about the role of human activities before industrial times, mainly because they make very different assumptions regarding the timing and spatial pattern of human land use in the past. All research performed to-date has been limited by the lack of spatially and temporally resolved datasets of past land cover that are corroborated with the observational record. In order to quantify the way in which humans interacted with their environment over the Holocene, the COEVOLVE project will 1) synthesize observations from paleoecological, archaeological, and historical records, 2) model human population and developments in technology, culture, and societal systems to map land cover change, and 3) quantify the emissions of greenhouse gases and aerosols as a result of anthropogenic deforestation, biomass burning, and soil erosion. We will accomplish these goals by combining archaeological and paleoecological data to reconstruct land cover change and by applying models of vegetation and human activities to simulate biogeochemical cycling. COEVOLVE is organized around four activities, 1) synthesis of observations of past land cover change from paleoecological and archaeological archives, 2) land cover modeling using state-of-the-art vegetation models, 3) building on first two activities, integrated human land use and biogeochemistry modeling in a case study for Europe, and 4) global modeling of human-environment interactions over the Holocene. With a new perspective on these subjects, the results of COEVOLVE will be a major contribution to our understanding of the recent history and present state of the Earth System. https://ufordat.uba.de/UFORDAT/pages/PublicRedirect.aspx?TYP=PR&DSNR=1028960
