Abstract:
... Scotland has one of the most uneven land ownership patterns in the world. In a country of 5.2 million people, about 969 people control 60% of the land. Over 20% of privately owned land in Scotland is held in some form of offshore or beneficial ownership (Committee on the Inquiry of Crofting, 2008). This land ownership pattern has a unique expression in the northern and western parts of the Scottis ...
anthropogenic activities; buildings; energy efficiency; environmental impact; experts; fuel cells; guidelines; hydrogen; industry; renewable energy sources; wind; Scotland
Abstract:
... Energy-efficient buildings can reduce human impact on the environment. Energy efficiency is not only concerned with generating more energy using fewer resources, nor reducing energy usage, but also it is about harnessing natural resources, such as wind and sun, to produce energy. The UK government is thus promoting the adoption of renewable energy in buildings. The Fuel-Cell Energy Systems (FCES), ...
Formica rufa; animals; ant nests; body size; nondestructive methods; physiology; social insects; spring; Scotland
Abstract:
... Colony size can be considered the analogue of the body size of a superorganism. Just as body size is important to the physiology of an individual animal, colony size correlates with the life-history and ecology of social insects. Although nest excavation and counting all individuals is the most accurate method for estimating colony size (or nest size), it has the major drawback of being destructiv ...
... Scotland is the largest Atlantic salmon (Salmo salar) producer in the EU with an output of over 150,000t, contributing over £500 million annually towards the economy. Production continues to increase, predominantly due to the increase in output per farm and reduction in losses due to infectious diseases. Farms are grouped within disease management areas whose boundaries are defined by where the cl ...
... Methods of assessment that depend upon commercial catch data can be undermined by misreporting or where parts of the catch, such as discards, are not accounted for. An age-structured model that makes use of survey data alone, and avoids this problem, is developed within a Bayesian framework so that routine stock summary statistics such as fishing mortality, recruitment and spawning stock biomass c ...
... RTG-P1 is a transgenic fish cell line producing luciferase under the control of the IFN-induced Mx rainbow trout gene promoter. This cell line was used to measure viraemia of Salmonid alphavirus (SAV), the cause of Salmon Pancreas Disease (SPD), a serious disease in farmed Atlantic salmon. Two SAV genotype 1 (SAV1) isolates were used in this study, F93-125 (tissue-culture adapted, from Ireland) an ...
... There is currently a deficiency of annually-resolved temperature series from the marine environment. We present a multiproxy reconstruction of Hebridean shelf sea (Tiree Passage; NW Scotland) spring sea surface temperatures (SSTs) for the period AD 1805–2010. The reconstruction is based on the growth increment series from the first absolutely dated annually-resolved multi-centennial Glycymeris gly ...
... A method of dating the marine growth circuli on Atlantic salmon (Salmo salar L.) scales is presented. Data were available for 54 salmon, intercepted as smolts at the completion of their downstream migration in the River North Esk, Scotland. Smolts were tagged, released, and recaptured as return adults after either one (1SW) or two (2SW) winters at sea. Dating of circuli was achieved by fitting a s ...

Abstract:
... In the past there have been several reasons for not fuelling large scale power plants with biomass instead of fossil fuels. For example, fossil fuels have higher energy density, their costs had been relatively low until recently, the required (large) amounts of biomass have not been readily available and the cost and environmental impact of road transportation of large quantities of biomass were c ...
Arabidopsis lyrata; altitude; evolutionary adaptation; gene flow; genetic variation; perennials; phenotype; reproductive performance; Iceland; Northern European region; Scotland; Sweden
Abstract:
... Widely distributed species, such as the perennial plant Arabidopsis lyrata, face a range of environmental conditions across space, creating selective pressures for local evolutionary adaptation. The species' fragmented distribution may reduce gene flow, which could either reduce or increase adaptive potential. The substantial variation in phenotypic traits observed across this species' northwester ...
... Sustainable control of nematode parasites in small ruminant production is a worldwide ambition. Development of anthelmintic resistance can severely impair small ruminant production. A practical approach to reduce selection pressure for anthelmintic resistance is to treat only a proportion of the flock (Targeted Selective Treatment), leaving a proportion of the nematode population untreated. The ai ...

Abstract:
... In the Scottish Highlands, Scots pine is at the north-western extreme of its wide natural distribution. Here, the remaining native populations are patchily distributed in highly variable environments, from the more continental, drier eastern Highlands to the milder, wetter Atlantic Ocean coast. As these pinewoods are the remnants of a naturally established forest, they form a valuable system for a ...
... This paper proposes a two-stage geophysical approach to map the vertical cracking and the structural integrity of flood embankments made up of clay geomaterials susceptible to fissuring. The first stage is based on a ‘coarse-resolution’ investigation using conventional electrical resistivity tomography (ERT) equipment to identify the fissured zones in the embankment. This step is complemented by a ...
... Although climate change is a major challenge facing the world today, a considerable proportion of the general public in the UK and other Western countries have been found to be sceptical of the issue. Given that livestock farming is a major contributor to climate change, this study explored the extent to which climate change scepticism prevailed among Scottish dairy farmers, the factors that affec ...
... We reported previously on a highly discriminatory pulsed field gel electrophoresis-based (PFGE) subtyping scheme for Salmonella enterica serovar Enteritidis (SE) and Salmonella Typhimurium (ST) that relies on combined cluster analysis of up to six restriction enzymes. This approach allowed for the high-resolution separation of numerous poultry-derived SE and ST isolates into several distinct clust ...

Abstract:
... Catchment scale nitrogen models are valuable tools for exploring how stream water quality is likely to be influenced by future changes in climate and land use. Many nitrogen modelling systems are highly complex and include too many calibration parameters to be confident in how these would be affected by changes in the catchment structure or meteorological drivers. This paper examines how successfu ...
... BACKGROUND: The red squirrel population in Great Britain has declined dramatically in recent decades, principally due to squirrelpox. Concern exists that red squirrels may become extinct nationally and, as there has been limited research in to diseases other than squirrelpox, this study aimed to identify additional causes of mortality. RESULTS: Post-mortem examinations on 163 red squirrels found d ...
... Invasive species can increase the susceptibility of ecosystems to disease by acting as reservoir hosts for pathogens. Invasive hosts are often sparsely recorded and not in equilibrium, so predicting their spatial distributions and overlap with other hosts is problematic. We applied newly developed methods for modelling the distribution of invasive species to the invasive shrub Rhododendron ponticu ...

Abstract:
... This study concludes that declines in growth rates of young-of-the-year European plaice (Pleuronectes platessa) (YOY plaice) during summer vary spatially and between years and that these dynamics are not driven by temperature, body size, or competition. RNA-predicted growth rates of YOY plaice on the west coast of Scotland declined linearly between mid-July and mid-September, with faster declines ...
... Trends in the incidence of multi-trunking at 21 sites in Glenbranter Forest in western Scotland are reported. Monitoring began in 1978 and continued for 30 years except at five sites that were felled. Incidence varied greatly between sites, from 9% up to 67% of trees multi-trunked at age 15–16 years, but rates declined slowly at nearly all sites after this peak. Decline was partly due to trunk sin ...
... Management intensification in agricultural grasslands is a major conservation concern. During the last 50 years, meadows have been drained, re-seeded with high-yielding grasses, treated with chemicals to remove pests and promote rapid growth, and mowing has become earlier and more frequent. This has severely reduced the reproductive success of several meadow-nesting bird species across large areas ...
