Abstract: Land-use and land-cover changes pose major challenges to local communities in many parts of the world. In the case of East Pokot in the Rift Valley of north-western Kenya, land-cover changes have a huge impact on livelihoods. While until the 1980s cattle husbandry was the prominent livelihood in the area, the socio-ecological dynamics of the past decades brought about major landscape changes. In this study, we present the land-cover changes over a period of 30 years (1985-2015), focusing on two processes in particular: the increasing bush encroachment in East Pokot (1), and the expansion of maize cultivation (2). The first process is identified as the land-cover change with the largest extent over the period of 30 years. The grass vegetation, which is essential for pastoral livelihoods and the successful rearing of cattle, has strongly declined and acacia bushes have encroached large areas all over East Pokot. The second process is a locally restricted process in the escarpment regions where precipitation is higher and conditions for farming are better, compared to the semi-arid lowland areas. Both processes, the slow bush encroachment of the region and the increasing cultivation of maize, describe different types of land-use and land-cover changes in East Pokot, which also relate to each other, as cattle husbandry is under pressure and agricultural practices are adopted over time. The land-cover changes described here, therefore, also entail social transformations of pastoral Pokot.

Abstract: The Atacama Desert, located on the western side of the Andes in northern Chile, harbours a range of endemic species adapted to hyperarid conditions. Vegetationis largely restricted to coastal fog oases and the Andean foothills, which are separated by a largely vegetation-free zone. Diversifications have been shown to be surprisingly recent in some Atacama clades, which is at odds with the extremely long history of aridity documented for this region. Here, we report the results of a molecular dating analysis of the Atacama genus Cristaria (Malvaceae) and its East Andean sister genus Lecanophora based on plastid sequence data.

Abstract: Bladelets are suggested as the hallmark of Early Upper Palaeolithic (EUP) industries. Bladelet-making is central in defining EUP technocomplexes and the debate is still ongoing. Here, new data on a significant sample of the stratified Early Ahmarian site of Al-Ansab 1 (Jordan) are presented. It is shown that bladelets constitute the majority of the blanks and the goal of the lithic production at the site. They are obtained through unipolar knapping of single platform cores, constraining a central area by means of embedded maintenance blade blanks and flank flakes. Bladelets are defined as the laminar blanks less than 12 mm wide. They are overwhelmingly represented in target products, i.e. straighter and more regular, while blades perform maintenance roles. Bladelet negatives are represented on laminar blanks and cores of all sizes. The presented analysis is part of a PhD project focusing on a comparison between bladelet-makings in different EUP sites along the putative “Eastern Trajectory”.

Abstract: The TR32DB Metadata Schema is a structured list of metadata properties chosen to describe all data in the TR32DB with accurate metadata properties and thus to improve their searchability. The entire data provided to the TR32DB can be described with a number of descriptive metadata properties (e.g. creator, title, abstract, keywords, etc.) and administrative or technical properties (e.g. file format, file type, rights statement, etc.). The stored data are organized in six main data type categories: Data, Geodata, Report, Picture, Presentation, and Publication. The TR32DB Metadata Schema is set up in two levels to describe the various types of data collected by the CRC/TR32 participants. The first level is the General level. This level includes metadata properties classified in seven categories: Identification, Responsible Party, Topic, File Details, Constraints, Geographic, and automatic generated Metadata Details. The second level is the Specific level and contains the data type specific metadata properties. Currently, six data types are included: Data, Geodata, Report, Picture, Presentation, and Publication. Publication takes a special position and is once again sub-divided into the sub-categories: Article, Book, Book Section, and Event Paper.

Abstract: Training Manual to use Terrestrial Systems Modeling Platform (TerrSysMP) as a numerical tool to develop a quantitative understanding of the complex soil-vegetation-atmosphere (SVA) interaction. The idealized setups in this manual, focus on the impact of root-zone soil moisture fluctuation on the diurnal energy partitioning and its feedback to the atmospheric boundary layer (ABL) dynamics. The interplay between subsurface hydrodynamics (e.g., (ψ-θ_vol ) relationship) and plant physiological properties (e.g., roughness, stomata conductance, root depth) is addressed using different plant functional types (PFTs) and soil textures (i.e., percentage of clay and sand).

Abstract: R-SWMS is a numerical model for simulating solute transport and water flow in and between the soil and the plant systems. The acronym stands for Modeling “Root-Soil Water Movement and Solute transport”. Based on the flow and transport equations in the 3D soil matrix and within the 3D root xylem network, it simulates the uptake of solute and water by plant roots for a growing plant. Three-dimensional root growth is function of environmental conditions (soil strength, temperature) and plant parameters (gravitropism, sensitivity to strength, etc.). The code has been used in several projects and labs around the world. An updated list of publications dealing with R-SWMS can be found at https://www.zotero.org/groups/r-swms. The handbook includes theory, numerics, input files, output files, installation, and some example calculations.

Abstract: Im Verlauf dieser Arbeit werden auf eine geographische und archäologische Einordnung folgend, die zur Analyse angewandten Methoden und die daraus resultierenden Erkenntnisse dargestellt und diskutiert. Um die Ergebnisse, die unter anderem paläoklimatische Aspekte bereithalten chronologisch einzuordnen und einen Kontext mit der Paläoumwelt herzustellen werden die heutigen Klimabedingungen und mögliche Ausprägungen der Paläoumwelt des Untersuchungsgebietes vorgestellt (Kapitel 4) und mit verschiedenen Paläoumweltarchiven des südosteuropäischen Raumes verglichen. Dies bezieht sich besonders auf den Zeitraum um 18 ka BP, was der Datierung der Fundschicht 3A entspricht (vgl. Kapitel 3.2) und das LGM. Die Ergebnisse der mikromorphologischen Analyse sollen die generellen Charakteristika des Westprofiles des Grabungsschnittes V (vgl. Kapitel 3.2) in der Blazi Cave herausstellen. Dies beinhaltet die Sedimentzusammensetzung, Dichte, Lagerung sowie die Verteilung der Komponenten und des enthaltenen archäologischen Materials, in den aus den Proben präparierten Dünnschliffen (vgl. Kapitel 7). Dies impliziert auch die Darstellung der Verhältnisse und Grenzen der Schichten, insbesondere der Schichten 2 und 3. Zudem soll die Trennung mehrerer potenzieller Besiedlungsphasen der Schichten 3A und 3B erfolgen. Ein besonderes Augenmerk gilt im Zuge der regionalen Forschungsgeschichte (vgl. Kapitel 1.1) der Detektion von Diskordanzen, Erosionsereignisse, die sich unter anderem in anthropogen oder biogen verlagerten Schichten zeigen können, für die allerdings auch fluviale oder kryoturbate Prozesse (vgl. Kapitel 5.3.4) in Betracht gezogen werden.

Abstract: By analysing satellite images of the area around Sodmein Cave numerous well-preserved surface remnants (terraces) could be documented. Surveys on these old terraces, showing mainly a dark desert pavement, yielded preferentially Pleistocene artefact concentrations. Hence, it became clear that these terraces represent parts of the former Pleistocene surface of the area. During surveying activities on such terraces a new archaeological site – preliminary named as “Sodmein Playa” 14/01 – was discovered around 3 km south-west of Sodmein Cave. On the surface a concentration of Middle Stone Age (MSA) artefacts, which seem to weather out of the sediments was observed. It was immediately clear that it did not occur in association with the gravel terraces but indicate a different geomorphological context. The artefacts did not exhibit the typical desert varnish of the terrace surfaces and they occurred at the surface of a sandy plain, seemingly lacustrine sediments (playa).
