Seaweed fertilisation impacts the chemical and isotopic composition of barley : Implications for analyses of archaeological skeletal remains

This research was partially funded by the European Social Fund and Scottish Funding Council as part of Developing Scotland's Workforce in the Scotland 2014–2020 European Structural and Investment Fund Programme. The contribution of staff from the University of the Highlands and Islands' Agronomy Institute and the James Hutton Institute to the field trial was supported by Rural and Environment Science and Analytical Services (RESAS) funding from the Scottish Government. GPS geolocation was performed by archaeologists of the Orkney Research Centre for Archaeology (ORCA). Stable isotope ratio measurements were performed at the Scottish Universities Environmental Research Centre (SUERC), East Kilbride, and elemental composition analysis was performed at the Trace Element Speciation Laboratory, Aberdeen (TESLA). MB would like to thank IM's family for their help collecting and storing the decomposing seaweed.Peer reviewedPostprintPostprin

The diet and management of domestic sheep and goats at Neolithic Makriyalos.

NoUntil recently, osteological studies into ancient diet and health have primarily focused upon human remains. As a result, these areas of research are still in their infancy in the field zoo-archaeology. Animals have paid a heavy price for many major human advances, such as those in agriculture and transport. This use (and often abuse) of animals has left many tell-tale signs in their teeth and bones. Along with the many advantages in animal exploitation have also come major problems for humans. Thus, infectious diseases passed from animals to humans must have long played a significant evolutionary role in the development of society. The zooarchaeological record could provide an extremely important temporal framework for exploring and understanding past and current issues of human health and animal welfare. This volume provides one of the first contributions to the field, and may stimulate many more

The Economies of Sheep and Goat Husbandry in Norse Greenland.

NoInsight into the relative importance of sheep and goat herding and of the economic significance of each species (i.e., milk vs. meat vs. wool) in Medieval Greenland is obtained through the application of Halstead et al.¿s (2002) criteria for the identification of adult ovicaprine mandibles to faunal assemblages from three Norse farmsteads: Sandnes, V52a, and Ø71S. The economic strategies identified are broadly comparable between the two species and the Eastern and Western Settlement sites examined, and are suggestive of the subsistence production of meat and milk. Comparison with farmsteads elsewhere in Greenland indicates that socio-economic status and/or farmstead size interacted with geographical location in determining the economic strategies employed by the Norse farmers. A broader use of resources and a more varied diet are evident at larger farmsteads in Greenland and this paper suggests that such sites would have been better able than their smaller counterparts to withstand environmental deterioration during the early Middle Ages. These analyses have also confirmed that goats were relatively more common in Norse sites in Greenland than in Norse sites in Iceland, Orkney, or Shetland

Dental Microwear in Grazing and Browsing Gotland Sheep (Ovis Aries) and its Implications for Dietary Reconstruction

NoMicrowear patterns and formation processes are examined in modern browsing and grazing Gotland sheep from Denmark. Clear differences in microwear patterning are identified between Gotland sheep, which included a high proportion of leaves, bark and twigs of deciduous trees and shrubs in their diet, and those which primarily had access to graze species, with the browsing group exhibiting enamel surfaces dominated by pitted microwear features, the grazers a predominance of striations. Analysis of abrasives in dung suggests that these trends can be attributed to higher levels of soil ingestion in the grazing population and are a consequence both of grassland management practices and height of feeding within the vegetation canopy. These findings question previous interpretations of microwear patterning in browsing and grazing ungulates, which have equated striated enamel features with the ingestion of high levels of opal phytoliths, and thus have significant implications for palaeodietary reconstruction in such species, both within archaeological and palaeontological contexts. To address further the implications of these results, comparison is made between the Gotland sheep and modern grazing and fodder-fed sheep and goats from elsewhere in Europe. It is concluded that dental microwear analysis has the potential to address questions relating to grassland management practices and the use of certain fodders, such as leafy-hay, but that it may ultimately prove more difficult to distinguish `fresh¿ browsing sheep from some grazing populations, specifically those in which levels of soil ingestion are reduced
