Far from being a simple annual round determined by the calendar, seasonality in human societies is a complex system of interdependence between humans and non-humans. It requires close attentiveness to the variability of soils, weather, topography, plants, and animals across both time and space. In this article, the author investigates mobile systems of interdependence that take advantage of topographical and seasonal variation. He uses a range of case studies from early modern Scotland and Cyprus, focusing on summer grazing in the uplands and lowland agriculture carried out by mountain communities. After a comparative discussion of seasonality, the article examines the role of topography and movement, and then puts the ‘margins at the centre’ in order to highlight the central role played by seasonal activity and movement in rural society.

Palisaded enclosures were huge enclosed spaces with timber boundaries found across Britain, Ireland, and Scandinavia in the Neolithic. Five such sites have been identified in Scotland dating to the later Neolithic, four of which have been excavated to varying degrees. These sites form the main focus of this paper, which draws in particular on interim results from the authors' excavations at Forteviot, Perth and Kinross, during 2007–2009. The palisaded enclosures of Scotland are part of a wider British and Irish tradition and there are a number of European parallels, the closest of which lie in southern Scandinavia. The palisaded enclosures in Scotland are tightly clustered geographically and chronologically, constructed in the centuries after 2800 cal BC. This paper explores the function, role, and meaning of palisaded enclosures in Scotland and more generally, drawing not just on the architecture of the monuments, but also the individual posts that were used to create the enclosures. The role of these monuments in reconstituting nature is also considered.

Stable isotope measurements and radiocarbon dates on 54 burials from northern Scotland document trends in marine protein consumption from the late Iron Age to the end of the Middle Ages. They illuminate how local environmental and cultural contingencies interrelated with a pan-European trend towards more intensive fishing around the end of the first millennium AD. Little use was made of marine foods in late Iron Age Orkney despite its maritime setting. Significant fish consumption appeared in the Viking Age (ninth to eleventh centuries AD), first in the case of some men buried with grave-goods of Scandinavian style but soon among both sexes in ‘Christian’ burials. There was then a peak in marine protein consumption from approximately the eleventh to the fourteenth centuries AD, particularly among men, after which the importance of fish-eating returned to Viking Age levels. The causes of these developments probably entailed a complex relationship between ethnicity, gender, Christian fasting practices, population growth, long-range fish trade and environmental change.

Models of the Mesolithic–Neolithic transition in Britain in recent years have tended to downplay the role of changes in the subsistence economy, emphasizing a very gradual adoption of new domesticated resources. This view has been particularly pervasive for the west coast of Scotland, which in the context of Britain presents a relatively marginal environment for farming. In this article, we challenge this too-quickly emerging orthodoxy through the presentation and discussion of both new and previously published stable isotope data and AMS dates. The palaeodietary information, while limited, strongly suggests a very rapid and complete change in the subsistence economy coincident with the earliest manifestations of the Neolithic on the west coast of Scotland early in the fourth millennium cal. BC. Whatever explanation is invoked to account for the transition needs to engage with the isotopic data. The possibility of colonization at some level needs to be seriously reconsidered.

The zooplankton taxa and their seasonal distribution are describeb for Loch Rusky, a shallow oligotrophic lake inthe central region of Scotland. 15 species were indentified: 11 Rotifera, 2 Cladocera and 2 Copepoda. Only 5 speciesPolyarthra remata, Keratella cochlearis, Filinia terminalis, Trichocerca sp. and Eudiaptomus gracilis occurred in sufficient numbers to facilitate a description of their seasonal pattern. The annual zooplankton variation was dominatedby rotifers for most of the year, but copepods (E. gracilis, Cyclops sp.) only were dominant in the epilimnion duringsummer. It is presumed that this pattern was the result of the rotifers faster rate of reproduction and higher grazingefficiency under oligotrophic conditions, as well as the decrease of larger zooplankton by the continuous programme of fish stocking in the lake.
