Change in propagule banks during prescribed burning: A tale of two contrasting moorlands2013 •
Moorlands on blanket bog are high-priority ecosystems from a conservation viewpoint in the British Isles; they are often managed through using prescribed burning to increase their productivity for sheep and Red grouse. However, there is an increasing demand to conserve these moorlands for other environmental services, e.g. carbon sequestration and water supplies. There is, therefore, a need for experimental evidence on the role that fire and fire rotation intervals have on these moorlands ecosystems for the development of ecologically-sound management plans. Here, the impact of prescribed burning on the propagule banks was evaluated at two contrasting geographical moorland locations differing in productivity, climate and past pollution history. Two different approaches were used; chronosequences of elapsed time since burning and a long-term replicated grazing and burning experiment (1954–2010) where different burning rotations were applied. The propagule banks in both moorlands were very species-poor and the species present were mainly common ones. The chronosequences showed that few species had significant effects with elapsed time since burning; the dominant Calluna vulgaris increased in the above-ground litter fraction which acted as a barrier to seed transfer to the underlying peat. Within the experiment, the seed bank of C. vulgaris and the frequency of occurrence of Sphagnum species increased as rotation-interval increased. It is suggested that prescribed burning rotations simultaneously at two temporal scales within a moorland landscape may be needed to conserve Sphagnum species, short rotation burns (every 10-years) to enhance its abundance in the vegetation and long-rotations (>55 years) to maintain Sphagnum propagules in the surface peat.

The Excavation of an Early Bronze Age Burnt Mound at Arisaig, Lochaber, HighlandDuring the upgrading of the A830(T), the 'Road to the Isles', the remains of a disturbed burnt mound deposit were discovered and later excavated during September and October 2005 by CFA Archaeology Ltd. This is the first such feature to have been excavated in this part of the Highlands.The burnt mound was discovered lying partly below a modern field bank on the edge of Arisaig during a trial trenching evaluation. Excavation demonstrated that the feature was formed in an active fluvial environment and that, despite the rural and boggy location, it had suffered considerable damage since its formation, caused by both the fluvial action of the adjacent stream and by a field drain. No evidence was found for either a hearth or a formal trough. The implication of a small assemblage of local quartz from within the burnt material is discussed. The charcoal assemblage is compared to spectra of pollen from contemporary deposits of peat in the area. Studies of the nature and origin of t...
This paper presents the results of a palaeoenvironmental investigation of riverine deposits containing charred heathland plant material, recovered during an archaeological survey of Gleann Mor Barabhais, Lewis, Western Isles of Scotland. This survey was conducted to identify Mesolithic occupation in the interior of the island and was undertaken as part of a wider project investigating the Mesolithic of the Western Isles. The recovery of carbonised material of Mesolithic date is discussed in light of the long-standing debate on detecting hunter-gatherer impact on environments using palaeoenvironmental records. The findings are compared to regional pollen sequences, where peaks in micro-charcoal levels and associated reductions in arboreal pollen are interpreted as evidence for anthropogenic fire ecology. These have been identified in areas where archaeological evidence for human occupation is absent. It is argued that this site reflects deliberate burning of vegetation by humans, most likely a small hearth, and therefore represents the first direct inferred evidence for the Mesolithic in the interior of the Western Isles.

Neolithic pits and Late Bronze Age roundhouses in the Upper Ury Valley, Aberdeenshire2019 •
Archaeological monitoring of works on a gas pipeline route in Aberdeenshire, north-west of Inverurie, resulted in the discovery and excavation of several groups of Neolithic pits and four Bronze Age roundhouses. The Neolithic pits were concentrated around the Shevock Burn, a small tributary of the Ury, and in the East and North Lediken areas to the north. They produced significant assemblages of Early Neolithic Impressed Ware and of Modified Carinated Bowl. The Bronze Age roundhouses included the heavily truncated remains of a post-built structure near Pitmachie, the remains of a pair of ring ditch structures near Little Lediken Farm, and another ring ditch structure close to Wrangham village.
Nowadays, corporations are moving towards sustainable management, and the social responsibility reports released by corporations show their sustainable behaviors. Aviation is a highpolluting industry with high carbon emissions, which makes it even more important for airlines to have a sustainable management plan. Consumers are also becoming more aware of the need to go green in order to minimize environmental damage and enhance human well-being. The purpose of this study is to examine the impact of corporate sustainability behaviors on airline ridership, the role of corporate image as a mediator, and the moderating effect of brand loyalty on ridership. A total of 412 questionnaires were collected from consumers who have traveled on airplanes. After deducting 50 invalid questionnaires, 362 valid questionnaires were collected, with a usability rate of 87.8%. Empirical factor analysis, reliability analysis, correlation analysis and hierarchical regression model were applied. The results of this study show that corporate sustainability behavior and corporate image have a significant positive effect on purchase intention, corporate image plays a part in mediating the effect of corporate sustainability behavior on purchase intention, and consumers' brand loyalty strengthens the effect of corporate image on purchase intention. Finally, this study proposes some recommendations for airlines to make sustainable behavior decisions.
