Native shrubs facilitate the establishment of oak seedlings in opencast coal mines rehabilitated to pastures Northern Spain, under a Mediterranean sub-humid climate. We evaluate soil changes as one possible facilitative effects nurse shrubs. hypothesize that on mining soils can improve edaphic properties directly and indirectly by reducing negative trampling grazing ungulates. Thus, we assessed...

Experiments based on the premise of uniformitarism are an effective tool to establish patterns taphonomic processes acting either before, or after, burial. One process that has been extensively investigated experimentally is impact trampling large mammal bones. Since marks caused by sedimentary friction strongly mimic cut made humans using stone tools during butchery, distinguishing origin such...

Several trials have been carried out by various authors concerning autonomous mowers, which are battery-powered machines. The effects of these machines on turfgrass quality and energy consumption thoroughly investigated. However, there still some aspects that not studied. Among these, random trajectory overlapping is one the most important. To investigate aspects, two RTK-GPS devices along with...

This paper deals with the ethnoarchaeological analysis of the spatial pattern of artefacts and ecofacts within two traditional pastoral huts (a dwelling and a seasonal dairy) in the uplands of Val Maudagna (Cuneo province, Italian western Alps). The composition of the ethnoarchaeological assemblages of the two huts was studied and compared; point pattern analysis was applied to identify spatial...
