Siedlungen der späten Bronze- und fru¨hen Eisenzeit in Südwestbulgarien.Vorbericht zu den deutsch-bulgarischen Forschungen 2012 im Struma- und Mestatal
-
After long-term surveys 2012 a German-Bulgarian team started excavations in the valleys of the rivers Struma and Mesta in south-western Bulgaria. The goal of our research is get a better understanding of the execution of power by the population of these mountain valleys as well as to reveal the processes of transfer and exchange of objects and technologies between the Aegean and the Danube regions. For this reason the excavations were conducted on the Late Bronze/Early Iron Age hillfort Kresna in the Mesta valley near Sandanski and on the Early Iron Age settlement Bresto near Raslog located close to the upper course of the Mesta river. Similar to the hillforts in the valley of Struma near Blagoevgrad, possible large-sized grain storages were exposed in Kresna. Bresto stands out for its massive fortified walls dated to the Early Iron Age as well as for the thousands secondary burnt daub fragments often supplied with plastic decorations. The comparison of various parts of the valleys of the rivers Struma and Mesta demonstrates the difference of interest for foreign objects and the acquisition of technologies on the micro-region level.

Significant loss of mitochondrial diversity within the last century due to extinction of peripheral populations in eastern gorillas
-
Species and populations are disappearing at an alarming rate as a direct result of human activities. Loss of genetic diversity associated with population decline directly impacts species’ long-term survival. Therefore, preserving genetic diversity is of considerable conservation importance. However, to assist in conservation efforts, it is important to understand how genetic diversity is spatially distributed and how it changes due to anthropogenic pressures. In this study, we use historical museum and modern faecal samples of two critically endangered eastern gorilla taxa, Grauer’s (Gorilla beringei graueri) and mountain gorillas (Gorilla beringei beringei), to directly infer temporal changes in genetic diversity within the last century. Using over 100 complete mitochondrial genomes, we observe a significant decline in haplotype and nucleotide diversity in Grauer’s gorillas. By including historical samples from now extinct populations we show that this decline can be attributed to the loss of peripheral populations rather than a decrease in genetic diversity within the core range of the species. By directly quantifying genetic changes in the recent past, our study shows that human activities have severely impacted eastern gorilla genetic diversity within only four to five generations. This rapid loss calls for dedicated conservation actions, which should include preservation of the remaining peripheral populations.

Sinopaninae and Arfianinae (Hyaenodontida, Mammalia) from the Early Eocene of Europe and Asia; evidence for dispersal in Laurasia around the Paleocene/ Eocene boundary and for an unnoticed faunal turnover in Europe
-
Hyaenodontida are represented in Europe by three subfamilies: Proviverrinae, Arfianinae and Sinopaninae. Here, we review all the specimens of Arfianinae and Sinopaninae known to date in Europe and Asia. A new Galecyon species is erected: Galecyon gallus nov. sp. We discuss the taxonomic position of the two Asian hyaenodontidans Anthracoxyaena palustris and Arfia langebadreae; the genus Anthracoxyaena is synonymized with Arfia. The analysis of the European and Asian arfianines and sinopanines provides new data concerning the dispersals and faunal events that occurred during the Early Eocene in Laurasia. The Arfianinae and Sinopaninae appeared in Europe around the Paleocene/Eocene boundary (reference-level MP7). The sinopanines are widespread in Europe; they are known in Dormaal (Belgium, reference-locality of the level MP7), Rians, Soissons, Pourcy, Try, Le Quesnoy (France), and Abbey Wood (England). The analysis of the paleogeographic distribution of all Oxyaenodonta and Hyaenodontida at and after the MP7 supports the existence of two European provinces: the North Province and Mesogean Province. We show that the Arfianinae and Sinopaninae rapidly disappeared from Europe; they are unknown in Avenay (reference-locality of the level MP8+9) and younger localities. Their disappearance from Europe is synchronous with that of the Oxyaenodonta. These observations support the existence of a faunal turnover, which occurred between the reference-levels MP7 (Dormaal) and MP8+9 (Avenay). The hypothesis of a dispersal from Europe to North America during the Paleocene-Eocene transition for the Arfianinae and Sinopaninae is supported. Moreover, the study of Arfianinae supports a dispersal from Europe to Asia around the P/E boundary, followed by a short period of endemic evolution. However, our study does not support a close relationship between Arfia and the ‘‘Arfia-like South Asian Proviverrinae’’ (Kyawdawia, Indohyaenodon, Paratritemnodon and Yarshea).

Sites with Holocene dung deposits in the Eastern Desert of Egypt: visited by herders?
-
The Tree Shelter and Sodmein Cave are two sites in the Egyptian Eastern Desert with stratified archaeological deposits. In Middle Holocene contexts of both sites, dated to the 7th millennium BP and later, animal dung has been found, in the shape of small concentrations of pellets at the Tree Shelter and of large accumulations at Sodmein Cave. The combination of several lines of evidence, including the size and weight of the excrements, the dimensions of the dung layers from Sodmein and the presence of hearths and artefacts inside them, and the species represented in the bone assemblages from Sodmein and the Tree Shelter, indicates that the dung was mostly deposited by herds of domestic ovicaprines. Sodmein Cave and the Tree Shelter belong to the oldest sites of the African continent where evidence for domestic small livestock has been attested. The importance and size of the herds seems to have been greater than would be suspected from the scant bone remains that were found. The visits to the caves were probably short but repeated over a long time period. Macrobotanical remains recovered from the dung suggest that these visits took place after seasonal winter rains.
