Opal phytoliths (microscopic silica bodies produced in and between the cells of many plants) are a very resilient, often preserved type plant microfossil. With exponentially growing number phytolith studies, standardization morphotype names description is essential. As first effort standardization, International Code for Phytolith Nomenclature 1.0 was published by ICPN Working Group Annals Botany 2005. A decade use code has prompted need to revise, update, expand improve it.
Abstract The third millennium BP crisis of the central African rainforest is not sufficiently understood. low resolution most pollen profiles and a large plateau calibration curve aggravate exact dating event, its causal climatic parameters are debated. We present high-resolution profile from swamp site Nyabessan in southern Cameroonian rainforest, covering period 3100-2300 cal yr BP. Between 3100 2500 BP, climate was favourable for regional evergreen forest with Caesalpiniaceae Lophira...
Because the genus Musa is not indigenous to Africa, remains of bananas in African archaeological or geological contexts indicate cultivation domesticated forms. During past 10 years, at least two claims have been made for discovery banana phytoliths middle late Holocene (Lejju et al. 2005, 2006, Mbida 2000, 2001, 2006). These finds met with universal acceptance (cf. Vansina 2003), part because application phytolith studies archaeology just beginning. In this paper, we examine current...
Many societal and environmental changes occurred between the 2nd millennium BC middle of AD in western Africa. Key amongst these were land use due to spread development agricultural strategies, which may have had widespread consequences for climate, hydrology, biodiversity, ecosystem services region. Quantification land-use influences potential feedbacks human natural systems is controversial, however, part because archaeological historical record highly fragmented time space. To improve our...
While a plethora of previous studies have described extremist propaganda content that seeks to radicalize individuals, there has been lack research on how individuals who become Islamists perceive and describe the they used. To address this issue explore personal drivers circumstances usage, we conducted in-depth interviews (n = 44) with radicalized Muslim prisoners former in Germany Austria. Our results found several types are used sequence as undergo cognitive behavioral radicalization....
The Bantu expansion, a major topic in African archaeology and history, is widely assumed to correlate with the spread of farming, but archaeological data on subsistence these putative early speakers are very sparse. However, finds domesticated pearl millet (Pennisetum glaucum) southern Cameroonian sites, dated between 400 200 BC, open new perspectives history agriculture Central rain forest. Linguistic evidence suggests that was part agricultural traditions speakers, has great extent been...
In semi-arid ecosystems where lacustrine sediments are rare, bio-proxies preserved in fluvial deposits needed to understand environmental changes. this study, we evaluate the potential of phytoliths as a bio-proxy Yamé River’s at Ounjougou (Mali, West Africa) covering middle late Holocene (7790–4000 cal. BP). soils, phytolith assemblages result mainly from decomposition local vegetation but alluvial deposits, taphonomy is more complex, depending on type transport and deposition. order define...
Since 2003, a joint research project of the universities Frankfurt and Tübingen (Germany) has explored changing interrelationship environment culture in forest-savanna regions West Central Africa. This paper provides first archaeological archaeobotanical results three field seasons rainforest southern Cameroun. Excavations were carried out at Bwambé Hill vicinity Kribi Atlantic coast as well Akonétye, Minyin Abang Minko’o, all located hinterland near Ambam. At sites number pit structures,...
We investigate how right-wing extremists use, perceive, and try to provoke news media coverage. Findings from qualitative interviews with former leaders of extremist groups in Germany, who served as key informants, show that reports on extremism are used trigger feelings being personally affected. Consequently, hostile-media third-person perceptions. These perceptions influence both emotions behaviors among extremists, for example, they cause strategically monitor exploit them political...
This study is the first to explore twin influences of online propaganda and news media on Islamists. We conducted 44 in-depth interviews with cognitively behaviorally radicalized Islamist prisoners in Austria as well former Islamists Germany Austria. found that had interdependent Islamists’ rejections non-Muslims Western politics, their willingness use violence commit suicide. Cognitively individuals were influenced by blamed for opposing Islam; this was reinforced mainstream reports...
Abstract Honey and other bee products were likely a sought-after foodstuff for much of human history, with direct chemical evidence beeswax identified in prehistoric ceramic vessels from Europe, the Near East Mediterranean North Africa, 7 th millennium BC. Historical ethnographic literature across Africa suggests products, honey larvae, had considerable importance both as food source making honey-based drinks. Here, to investigate this, we carry out lipid residue analysis 458 pottery Nok...
