    Sammanfattning : This thesis deals with the influence of the notion of climate in Sweden 1750-1800. The theory of climate played an important role in many contexts in eighteenth century Sweden. In different ways it came to be used in historiography, political economy and, in time, in the study of man in the emerging discipline of anthropology. LÄS MER

    Sammanfattning : The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. LÄS MER

  5. 5. Quantifying ecological resilience in lakes – bridging theory and management

    Detta är en avhandling från ; Department of Aquatic Sciences and Assessment, Swedish University of Agricultural Sciences

    Författare :Didier Ludovic Baho; Sveriges lantbruksuniversitet.; [2015]

    Sammanfattning : Ecological resilience, defined as the capacity of an ecosystem to withstand disturbances without losing original structures, processes and functions, has remained elusive and challenging to quantify. In this thesis, two methods were used to assess the resilience of aquatic communities to different stressors and management practices. LÄS MER
