Article Reference The Late Neolithic Michelsberg culture – just ramparts and ditches? A supraregional comparison of agricultural and environmental data
The archaeobotanical state of research from sites of the Michelsberg and the Bischheim culture (5th/4th millenium BC) in France, Belgium, southern Netherlands and Germany has been compiled and discussed in the context of archaeological, climatological and biological data. Compared with Bischheim and the Middle Neolithic the farmers of the Michelsberg culture had a reduced crop spectrum with emphasis on cereal growing. It is still under debate, from where the tetraploid wheat has been introduced. Possibly the growing of oil/fibre plants was abandoned by the Michelsberg farmers. Interestingly the same reduced crop spectrum is found somewhat later in the distribution area of the Funnelbeaker culture as well as in the Neolithic sites of Great Britain and Ireland. Climatic causes are not likely for this phenomenon. Instead, zoologial and botanical results point to an agricultural system with more emphasis on stock farming, which might have been based on a cultural decision.

Article Reference chemical/x-molconn-Z The link between microbial diversity and nitrogen cycling in marine sediments is modulated by macrofaunal bioturbation
Objectives : The marine benthic nitrogen cycle is affected by both the presence and activity of macrofauna and the diversity of N-cycling microbes. However, integrated research simultaneously investigating macrofauna, microbes and N-cycling is lacking. We investigated spatio-temporal patterns in microbial community composition and diversity, macrofaunal abundance and their sediment reworking activity, and N-cycling in seven subtidal stations in the Southern North Sea. Spatio-Temporal Patterns of the Microbial Communities : Our results indicated that bacteria (total and beta-AOB) showed more spatio-temporal variation than archaea (total and AOA) as sedimentation of organic matter and the subsequent changes in the environment had a stronger impact on their community composition and diversity indices in our study area. However, spatio-temporal patterns of total bacterial and beta-AOB communities were different and related to the availability of ammonium for the autotrophic beta-AOB. Highest bacterial richness and diversity were observed in June at the timing of the phytoplankton bloom deposition, while richness of beta-AOB as well as AOA peaked in September. Total archaeal community showed no temporal variation in diversity indices. Macrofauna, Microbes and the Benthic N-Cycle : Distance based linear models revealed that, independent from the effect of grain size and the quality and quantity of sediment organic matter, nitrification and N-mineralization were affected by respectively the diversity of metabolically active beta-AOB and AOA, and the total bacteria, near the sediment-water interface. Separate models demonstrated a significant and independent effect of macrofaunal activities on community composition and richness of total bacteria, and diversity indices of metabolically active AOA. Diversity of beta-AOB was significantly affected by macrofaunal abundance. Our results support the link between microbial biodiversity and ecosystem functioning in marine sediments, and provided broad correlative support for the hypothesis that this relationship is modulated by macrofaunal activity. We hypothesized that the latter effect can be explained by their bioturbating and bio-irrigating activities, increasing the spatial complexity of the biogeochemical environment.
