Spatio-temporal feeding selection of red deer in a mountainous landscape

Understanding the dietary consumption and selection of wild populations of generalist herbivores is hampered by the complex array of factors. Here, we determine the influence of habitat, season, and animal density, sex, and age on the diet consumption and selection of 426 red deer (Cervus elaphus scoticus) culled in Fiordland National Park, New Zealand. Our site differs from studies elsewhere both in habitat (evergreen angiosperm-dominated forests) and the intensity of hunting pressures. We predicted that deer would not consume forage in proportion to its relative availability, and that dietary consumption would change among and within years in response to hunting pressures that would also limit opportunities for age and sex segregation. Using canonical correspondence analysis, we evaluated the relative importance of different drivers of variation in diet consumption assessed from gut content and related these to available forage in the environment. We found that altitude explained the largest proportion of variation in diet consumption, reflecting the ability of deer to alter their consumption and selection in relation to their foraging grounds. Grasses formed a high proportion of the diet consumption, even for deer culled several kilometres from the alpine grasslands. In the winter months, when the alpine grasslands were largely inaccessible, less grass was eaten and deer resorted to woody plants that were avoided in the summer months. Surprisingly, there were no significant dietary differences between adults and juveniles and only subtle differences between the sexes. Sex-based differences in diet consumption are commonly observed in ungulate species and we suggest that they may have been reduced in our study area owing to decreased heterogeneity in available forage as the diversity of palatable species decreased under high deer browsing pressures, or by intense hunting pressure. © 2009 The Authors.

Emotional response to images of wind turbines: A psychophysiological study of their visual impact on the landscape

Social acceptance for wind turbines is variable, providing a challenge to the implementation of this energy source. Psychological research could contribute to the science of climate change. Here we focus on the emotional responses to the visual impact of wind turbines on the landscape, a factor which dominates attitudes towards this technology. Participants in the laboratory viewed images of turbines and other constructions (churches, pylons and power-plants) against rural scenes, and provided psychophysiological and self-report measures of their emotional reactions. We hypothesised that the emotional response to wind turbines would be more negative and intense than to control objects, and that this difference would be accentuated for turbine opponents. As predicted, the psychophysiological response to turbines was stronger than the response to churches, but did not differ from that of other industrial constructions. In contrast with predictions, turbines were rated as less aversive and more calming compared with other industrial constructions, and equivalent to churches. Supporters and non-supporters did not differ significantly from each other. We discuss how a methodology using photo manipulations and emotional self-assessments can help estimate the emotional reaction to the visual impact on the landscape at the planning stage for new wind turbine applications.

Navigating the Borderlands: Brian McGilloway as Contemporary Cartographer of the Liminal in the Ulster Landscape

Set in the borderlands between Letterkenny and Derry-Londonderry, a landscape scarred by geological fold, river and cartographer’s pen, the Ulster crime novelist Brian McGilloway chronicles the hopes and fears of a contemporary society unable to escape a complicated history, redolent and entwined with the voices of its ‘ghosts of its past.’ Through his choice of chief protagonist, An Garda Síochána officer Benedict Devlin, McGilloway turns detective to critically investigate the both the seemingly straightforward and the unseen dwelling in the rural Ulster landscape. Following in the footsteps of Nordic and Tartan Noir in making commentary on current societ,y McGilloway recognises the importance of the past in trying to reach an understanding of the present. His critique however goes beyond criminal behaviour motivated primarily by politics or religion, allowing a deeper and more meaningful diagnosis of the ‘state of the nation’. Place, name and event become especially important in contextualising the liminality of McGilloway’s real rural border settings. In doing so, McGilloway continues in the rich tradition of Ulster poet such as Heaney, MacNiece, Muldoon and Hewitt in trying to rationalise the man-made amidst the elemental in the land of both the ‘Planter & The Gael.’ History, language, tradition and the sacral are all instruments of investigation in helping McGilloway present a revealing pathology and atlas of our times to his readers. Turning literary investigator, the author contends that there is much to learn from this physiography, not just for the borderlands region, but for the wider countryside and society beyond.

Navigating and exploring the ASD-friendly landscape

As a society we have a responsibility to provide an inclusive built environment. For those with Autistic Spectrum Disorder (ASD) however, the world can be a frightening, difficult and confusing place. The challenge of integrating more fully into society can be distanced by an alienating built environment. This is particularly debilitating for younger children who can find themselves detached from learning and interaction with their peers by uncomfortable surroundings. Subsequently there has been a growing interest in promoting ASD-friendly environments, especially in a school setting. Strategies to date have generally followed a widely accepted reductionist or generalist approach. However, the authors now contend that there needs to be a greater discussion of what truly constitutes an ASD-friendly environment, in conjunction with investigating what strategies best articulate a progressive approach to supporting those, and especially the young, with ASD in our built environment. Hence this paper first introduces some of the challenges faced by those with ASD in trying to cope with their surroundings. It then outlines a triad of challenges to overcome when considering what truly constitutes an ASD-friendly environment. The authors then highlight the need and advantage of supporting change and adaption in our shared inhabited landscape through providing both choice and reassurance for the child with ASD. It is hoped that by increasing awareness and then questioning what genuinely constitutes an ASD-friendly environment, it might ultimately help facilitate greater inclusion of the ASD child into mainstream education and society at large.

A stacked Late Quaternary fluvio-periglacial sequence from the Axe valley, southern England with implications for landscape evolution and Palaeolithic archaeology

The current model of mid-latitude late Quaternary terrace sequences, is that they are uplift-driven but climatically controlled terrace staircases, relating to both regional-scale crustal and tectonic factors, and palaeohydrological variations forced by quasi-cyclic climatic conditions in the 100 K world (post Mid Pleistocene Transition). This model appears to hold for the majority of the river valleys draining into the English Channel which exhibit 8–15 terrace levels over approximately 60–100 m of altitudinal elevation. However, one valley, the Axe, has only one major morphological terrace and has long-been regarded as anomalous. This paper uses both conventional and novel stratigraphical methods (digital granulometry and terrestrial laser scanning) to show that this terrace is a stacked sedimentary sequence of 20–30 m thickness with a quasi-continuous (i.e. with hiatuses) pulsed, record of fluvial and periglacial sedimentation over at least the last 300–400 K yrs as determined principally by OSL dating of the upper two thirds of the sequence. Since uplift has been regional, there is no evidence of anomalous neotectonics, and climatic history must be comparable to the adjacent catchments (both of which have staircase sequences) a catchment-specific mechanism is required. The Axe is the only valley in North West Europe incised entirely into the near-horizontally bedded chert (crypto-crystalline quartz) and sand-rich Lower Cretaceous rocks creating a buried valley. Mapping of the valley slopes has identified many large landslide scars associated with past and present springs. It is proposed that these are thaw-slump scars and represent large hill-slope failures caused by Vauclausian water pressures and hydraulic fracturing of the chert during rapid permafrost melting. A simple 1D model of this thermokarstic process is used to explore this mechanism, and it is proposed that the resultant anomalously high input of chert and sand into the valley during terminations caused pulsed aggradation until the last termination. It is also proposed that interglacial and interstadial incision may have been prevented by the over-sized and interlocking nature of the sub-angular chert clasts until the Lateglacial when confinement of the river overcame this immobility threshold. One result of this hydrogeologically mediated valley evolution was to provide a sequence of proximal Palaeolithic archaeology over two MIS cycles. This study demonstrates that uplift tectonics and climate alone do not fully determine Quaternary valley evolution and that lithological and hydrogeological conditions are a fundamental cause of variation in terrestrial Quaternary records and landform evolution.

Stated preference methods and landscape ecology indicators: an example of transdisciplinarity in landscape economic valuation

This paper addresses the representation of landscape complexity in stated preferences research. It integrates landscape ecology and landscape economics and conducts the landscape analysis in a three-dimensional space to provide ecologically meaningful quantitative landscape indicators that are used as variables for the monetary valuation of landscape in a stated preferences study. Expected heterogeneity in taste intensity across respondents is addressed with a mixed logit model in Willingness to Pay space. Our methodology is applied to value, in monetary terms, the landscape of the Sorrento Peninsula in Italy, an area that has faced increasing pressure from urbanization affecting its traditional horticultural, herbaceous, and arboreal structure, with loss of biodiversity, and an increasing risk of landslides. We find that residents of the Sorrento Peninsula would prefer landscapes characterized by large open views and natural features. Residents also appear to dislike heterogeneous landscapes and the presence of lemon orchards and farmers' stewardship, which are associated with the current failure of protecting the traditional landscape. The outcomes suggest that the use of landscape ecology metrics in a stated preferences model may be an effective way to move forward integrated methodologies to better understand and represent landscape and its complexity.
