Abstract: The here documented GIS map and dataset contains a collection of Last Glacial Maximum (LGM, ~21k yBP) paleoenvironmental data. It is the first result of a project that aims to acquire, produce and publish GIS datasets from non-GIS based sources such as analogous maps, textual informations or figures of scientific publications for prehistoric time slices. In combination with modelling results and already available GIS-datasets related to the mentioned time frame, it should enable other researchers and members from other projects to use the maps in their work, properly cited and referenced. The map shows LGM land ice sheets, paleo-stream networks and inland water in Europe, a sea-level adapted (-120m) land mass and a Köppen-Geiger climate classification derived from climate model data.

Abstract: This is a plugin for QGIS to interface the openModeller software package. OpenModeller is a software framework for species’ potential distribution modelling. The package includes (among other program files) the om_console.exe executable which is used for the modelling process. The program file is controlled by a configuration file and needs several files as input data. The configuration file contains the paths to the input data, configuration parameters for the output data and the selected modelling algorithm (GARP, Bioclim, Maxent, etc.). Further input data is the occurrence file which contains the occurrence data for a species with a label and geographic coordinates in longitude/latitude notation. The last part is the environmental data that contains environmental variables such as climate or topographic data. The plugin enables the user to select point and raster layers and a modelling algorithm in QGIS which are then converted (in case of the occurrence data) and copied to a new folder structure and written into the configuration file accordingly, depending on the selection and assignment. Subsequently, the generated files and project folder can be directly used by the om_console executable.

Abstract: This keynote speech was held at the 11th Conference on Hunting and Gathering Societies (CHAGS 11) in Vienna, Austria, in September 2015. It comments on the establishment of the International Society for Hunter-Gatherer Research and the new Journal “Hunter Gatherer Research” and it presents ideas about the future orientation of this interdisciplinary field of study. Drawing on examples from first-hand ethnography with the Batek of Malaysia, with Australian Aborigines and with Hai//om San from southern Africa the contribution outlines a new approach in hunter-gatherer studies that explores the notion of “hunter-gatherer situations”.

Abstract: Our research interests in palaeo-studies in East Africa remain high, partly because of the Out-of-Africa hypotheses predicting Homo sapiens origin to be situated in East Africa. Since several decades archaeologists and geoscientists explore suitable sites to answer related questions. Simultaneously, analytical methods applied to the archives improved in their sensibility or resolution over the given time. The amount of published scientific data is enormous, but has to be carefully checked on their robustness compared to modern standards. Therefore, it is necessary to compile datasets and excerpt the given data that are source of scientific interpretations (e.g., palaeoenvironment, palaeoclimate, evolution patterns, time models etc.). In addition, the names of the study sitesin East Africa are often transcribed from different languages or hold several synonyms for various reasons. Thus, we decided to use a semantic wiki to have the advantage of queryable structured data combined with the ability of web based frontend for collaborative editing of the content. The presented application is based on Semantic Mediawiki (SMW), an extension of the famous Mediawiki software, the widely used wiki system mostly developed and maintained by the Wikimedia foundation as the software base of Wikipedia. The SMW extension allows to enter structured semantic data on wiki pages. This data can then be queried through several interfaces within the wiki and the Mediawiki API as well as an SPARQL endpoint for access from external applications. Query results can be exported in several well known formats, such as CSV, XML, JSON, and more. It is also possible to display query results directly in the wiki, using a number of provided display formats, like tables, data graphs or maps. The presented system allows to collaboratively develop and maintain a data basis and thus implements a collaborative research environment (CRE). The data can be exported for use in scientific software packages for e.g. statistical or GIS analysis. A further outcome of the approach is a domain data model of the structured information stored in the system, which can be formalised and mapped to existing data bases to allow data integration between applications. Details of published and unpublished archaeological and geological sites/localities in East Africa are collected in the presented wiki including their bibliographical reference. For example from sediment records, results from available sedimentological/chemical/biological proxy data (e.g., grain size, total organic carbon, stable isotopes, diatoms, ostracods, magnetic susceptibility) are copied into the database including their spatial resolution. Related dating samples (i.e., 14C, OSL, TSL) are also included with their metadata and lab-codes.

Abstract: In the recent past data base systems providing information on early humans and their environment are becoming more and more important and increase rapidly in number. However, this increase in different DB systems is concomitant with an increasing redundancy in the digital information stored in these database systems. Therefore, in this study we explore ways to reduce redundancies due to multiple storage of data and, hence, we show solutions to minimize the requirements to store and manage digital information in the prehistory and paleoenvironment domains. The example is based on the database systems of the DFG financed SFB 806: “Our Way to Europe” and the Heidelberg Academy of Sciences and Humanities project entitled: “The Role Of Culture in Early Expansion of Humans (ROCEEH). We focus especially on the spatial data available in both systems as well as on the environmental information. Therefore, we examine and test exchange interfaces based on Spatial Data Infrastructure technology (OGC Standards) and metadata/schema mappings. The poster presents currently implemented interfaces of both data base systems in terms of their main commonalities and differences. Based on this overview, we discuss ways of direct links between the DB systems. Moreover, we identify procedures that need to be developed in the future to integrate and exchange data between both systems. We show that DB-linking activities based on the OGC standards yield valuable results and lead to a more efficient, sustainable management of these DB systems providing added values for the related research groups.

Abstract: Sodmein Cave can be interpreted as one of the rare living sites in the time frame between 120 ka and 7 ka before today in northeast Africa. Nowadays, a hyperarid climate is dominant in the area, but the excavated sequence - with more than 4 m of stratified occupation debris of mainly Middle Stone Age (MSA) deposits - indicate for the Pleistocene regional wetter conditions.Main objective of the PhD is to understand the site formation and sediment accumulation within the cave and to derive environmental changes outside the cave from these results. Altogether, with geomorphological investigation of different archives in the area around Sodmein Cave, we get an idea of the palaeoenvironment and landscape evolution during the last 120 ka. One focus of research is directed to old wadi terraces with strongly developed desert pavement formation and MSA artefact concentrations, which are most likely in-situ located. With attention of the archaeological results, the PhD will present a integrated geoarchaeological work and a better understanding of the palaeoenvironment and landscape evolution in the Egyptian Eastern desert.

Abstract: The mountainous Eastern Desert of Egypt is an extremely eroded environment where the conditions to encounter Pleistocene palaeoenvironmental geoarchives are very rare. Dominated by outcrops of Precambrian basement, the drainage system is characterized by relatively short wadis with small catchment areas (figure 1). The limestone hogback of Djebel Duwi is one of the exceptional regions within the Eastern Desert which provides a significant amount of quaternary deposits, mainly wadi terraces at the eastern and western side of Djebel Duwi, caused by the existing tectonic basin (figure 2). It also serves the location of the archaeological site of Sodmein Cave, where latest dating results of heated chert evidence human presence at the site during MIS 5 (Schmidt et al. 2015). Nowadays, a hyperarid climate is dominant in the area, but the cave deposits have indicate for the Pleistocene regional wetter conditions. In case of a lack of natural sediment sinks beside the cave, no sedimentological investigations are possible to achieve the landscape evolution and therefore, the morphometric analysis of the wadi system is one key feature for the reconstruction of the former terrain and geomorphic processes.

Abstract: Hassi Berkane (“Wellspring Berkane”) is an Iberomarusian site in the Nador Province in Northeastern Morocco. A thick escargotière visible in construction trenches and underneath the rockshelter on the outskirts of the town was investigated by the team from the CRC 806 in 2014. Profiles in the trench were documented and two boreholes were drilled underneath the rockshelter. The team found lithics and faunal remains in the cores alongside terrestrial snail shell fragments, as well as multiple charcoals taken for radiocarbon dating. From the profiles and the drillings, a settlement layer of ca. 2000 square meters could be reconstructed. Not only the sheltered space beneath the rockshelter was used, but also a large open air space to the north.
