The Gravettian from a palaeodemographic point of view","maintainer":"Isabell Schmidt","maintainer_email":"isabell.schmidt@uni-koeln.de","notes":"The Gravettian is known for its technological innovations and artisanal craftwork. At the same time, continued climatic deterioration led to the coldest and driest conditions since the arrival of Homo sapiens sapiens in Europe. This article examines the palaeodemographic development and provides regionally differentiated estimates for both the densities and the absolute numbers of people. A dramatic population decline characterises the later part of the Gravettian, while the following Last Glacial Maximum experienced consolidation and renewed growth. The results suggest that the abandonment of the northern areas was not a result of migration processes, but of local population extinctions, coinciding with a loss of typological and technological complexity. Extensive networks probably assured the maintenance of a viable population.\r\n\r\nKeywords: Western Europe, Central Europe, Gravettian, palaeodemography, migration/local extinction, cultural complexity, minimum viable population","type":"literature","resources":[{"description":"","format":"PDF","url":"http://data/sfb806db/E/E1/Maier_Zimmermann_2017.pdf","created":"2021-09-29T11:09:19.017024","state":"active","package_id":"750a9c9f-196c-4f75-9d0b-318b742181dc","last_modified":"2021-10-25T07:10:51","id":"faefe8ea-291b-4a4d-b5de-e43d704e28bb","name":"Maier_Zimmermann_2017.pdf"}],"tags":[],"extras":[{"key":"bibtex:address","value":""},{"key":"bibtex:author","value":"Maier, Andreas and Zimmermann, Andreas"},{"key":"bibtex:booktitle","value":""},{"key":"bibtex:citation","value":""},{"key":"bibtex:doi","value":"org/10.15184/aqy.2017.37"},{"key":"bibtex:editor","value":""},{"key":"bibtex:howpublished","value":""},{"key":"bibtex:isbn","value":""},{"key":"bibtex:journal","value":"Antiquity"},{"key":"bibtex:month","value":""},{"key":"bibtex:number","value":"357"},{"key":"bibtex:organization","value":""},{"key":"bibtex:pages","value":"573\u2013588"},{"key":"bibtex:publisher","value":""},{"key":"bibtex:school","value":""},{"key":"bibtex:series","value":null},{"key":"bibtex:type","value":"article"},{"key":"bibtex:key","value":""},{"key":"bibtex:url","value":""},{"key":"bibtex:volume","value":"91"},{"key":"bibtex:year","value":"2017"}],"groups":[{"image_url":"http://crc806db.uni-koeln.de/fileadmin/template/images/projects/imageE1.png","name":"e1"}],"author":"","author_email":false}{"help":"Update a dataset (package).\n\n You must be authorized to edit the dataset and the groups that it belongs\n to.\n\n Plugins may change the parameters of this function depending on the value\n of the dataset's ``type`` attribute, see the ``IDatasetForm`` plugin\n interface.\n\n For further parameters see ``package_create()``.\n\n :param id: the name or id of the dataset to update\n :type id: string\n\n :returns: the updated dataset (if 'return_package_dict' is True in the\n context, which is the default.
