Published: July 2010

SUMMARYIt is predicted that climate change will increase not only seasonal air and soil temperatures in northern Europe but also the variability of rainfall patterns. This may influence temporal soil moisture regimes and the growth and yield of winter wheat. A lysimeter experiment was carried out in 2008/09 with three factors: rainfall amount, rainfall frequency and soil warming (two levels in each factor), on sandy loam soil in Denmark. The soil warming treatment included non-heated as the control and an increase in soil temperature by 5°C at 100 mm depth as heated. The rainfall treatment included the site mean for 1961–90 as the control and the projected monthly mean change for 2071–2100 under the International Panel on Climate Change (IPCC) A2 scenario for the climate change treatment. Projected monthly mean changes in rainfall compared to the reference period 1961–90 show, on average, 31% increase during winter (November–March) and 24% decrease during summer (July–September) with no changes during spring (April–June). The rainfall frequency treatment included mean monthly rainy days for 1961–90 as the control and a reduced frequency treatment with only half the number of rainy days of the control treatment, without altering the monthly mean rainfall amount. Mobile rain-out shelters, automated irrigation system and insulated heating cables were used to impose the treatments.Soil warming hastened crop development during early stages (until stem elongation) and shortened the total crop growing season by 12 days without reducing the period taken for later development stages. Soil warming increased green leaf area index (GLAI) and above-ground biomass during early growth, which was accompanied by an increased amount of nitrogen (N) in plants. However, the plant N concentration and its dilution pattern during later developmental stages followed the same pattern in both heated and control plots. Increased soil moisture deficit was observed only during the period when crop growth was significantly enhanced by soil warming. However, soil warming reduced N concentration in above-ground biomass during the entire growing period, except at harvest, by advancing crop development. Soil warming had no effect on the number of tillers, but reduced ear number and increased 1000 grain weight. This did not affect grain yield and total above-ground biomass compared with control. This suggests that genotypes with a longer vegetative period would probably be better adapted to future warmer conditions. The rainfall pattern treatments imposed in the present study did not influence either soil moisture regimes or performance of winter wheat, though the crop receiving future rainfall amount tended to retain more green leaf area. There was no significant interaction between the soil warming and rainfall treatments on crop growth.

BackgroundNicotine dependence has been shown to represent a heritable condition, and several research groups have performed linkage analysis to identify genomic regions influencing this disorder though only a limited number of the findings have been replicated.MethodIn the present study, a genome-wide linkage scan for nicotine dependence was conducted in a community sample of 950 probands and 1204 relatives recruited through the University of California, San Francisco (UCSF) Family Alcoholism Study. A modified version of the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) with additional questions that probe nicotine use was used to derive DSM-IV nicotine dependence diagnoses.ResultsA locus on chromosome 2q31.1 at 184 centiMorgans nearest to marker D2S2188 yielded a logarithm (base 10) of odds (LOD) score of 3.54 (point-wise empirical p=0.000012). Additional peaks of interest were identified on chromosomes 2q13, 4p15.33-31, 11q25 and 12p11.23-21. Follow-up analyses were conducted examining the contributions of individual nicotine dependence symptoms to the chromosome 2q31.1 linkage peak as well as examining the relationship of this chromosomal region to alcohol dependence.ConclusionsThe present report suggests that chromosome 2q31.1 confers risk to the development of nicotine dependence and that this region influences a broad range of nicotine dependence symptoms rather than a specific facet of the disorder. Further, the results show that this region is not linked to alcohol dependence in this population, and thus may influence nicotine dependence specifically.
The death(s) of close friends and family moderate genetic influences on symptoms of major depressive disorder in adolescents

Published: July 2010

BackgroundPrior work has suggested that genetic influences on major depressive disorder (MDD) may be activated by the experience of negative life events. However, it is unclear whether these results persist when controlling for the possibility of confounding active gene–environment correlations (rGE).MethodWe examined a sample of 1230 adopted and biological siblings between the ages of 10 and 20 years from the Sibling Interaction and Behavior Study. MDD was measured via a lifetime DSM-IV symptom count. Number of deaths experienced served as our environmental risk experience. Because this variable is largely independent of the individual's choices/behaviors, we were able to examine gene–environment interactions while circumventing possible rGE confounds.ResultsBiometric analyses revealed pronounced linear increases in the magnitude of genetic influences on symptoms of MDD with the number of deaths experienced, such that genetic influences were estimated to be near-zero for those who had experienced no deaths but were quite large in those who had experienced two or more deaths (i.e. accounting for roughly two-thirds of the phenotypic variance). By contrast, shared and non-shared environmental influences on symptoms of MDD were not meaningfully moderated by the number of deaths experienced.ConclusionsSuch results constructively replicate prior findings of genetic moderation of depressive symptoms by negative life events, thereby suggesting that this effect is not a function of active rGE confounds. Our findings are thus consistent with the notion that exposure to specific negative life events may serve to activate genetic risk for depression during adolescence.
Sola scriptura and the regula fidei: the Reformation scripture principle and early oral tradition in Martin Chemnitz' Examination of the Council of Trent
Authors: Merrick James R. A. 
Published: July 2010

AbstractHow could a sixteenth-century Protestant reformer who championed sola scriptura defend against the charge of novelty? In particular, how did a reformer understand the post-apostolic church's regula fidei as a possible early counter-precedent to the scripture principle? And what does the answer to these questions tell us about the Reformation scripture principle? These are the principal questions with which this article is concerned. By looking at Martin Chemnitz's Examination of the Council of Trent, I show that Chemnitz rebutted the charge of novelty by returning the favour, that is, he rhetorically situated the Catholics alongside the early Gnostics since both believed in an oral tradition that differed substantially from scripture. Furthermore, I find that Chemnitz contended that Irenaeus’ and Tertullian's use of the regula fidei actually supported sola scriptura since these fathers never posited a substantial distinction between scripture and tradition and, in fact, held that the content of the rule was recorded in scripture. Chemnitz concluded that Protestants holding the scripture principle are the ones who are truly faithful to early church tradition in general and the rule in particular.
The Righteousness of God in Psalms and Romans
Authors: Turner Geoffrey 
Published: July 2010

AbstractPaul quoted extensively from scripture, especially in Romans. Many of these citations are from the Psalms, using the Septuagint. Paul could have found all his vocabulary and concepts for ‘justification by faith’ in the Psalms. The Psalms contain a doctrine of ‘righteousness through faithfulness’: God is righteous by forming a covenant with Israel, and proves his righteousness by remaining faithful to that covenant despite Israel's failings. He will remain faithful to the end by vindicating his righteous ones when they are oppressed by the ungodly. Israelites are righteous by having been elected to the covenant and will remain righteous through faithfulness to God, the marks of which are the avoidance of idolatry and keeping the law. Far from rejecting this Old Testament inheritance, Paul takes over this doctrine of ‘righteousness through faithfulness’ as it stands in the Psalms (Romans 1:18–3:20) and then christologises it (from 3:21). The mark of faithfulness to God now is no longer the law, however, but faithfulness to Christ, who is himself the model of faithfulness and what it is to be righteous. This understanding of how one becomes righteous is located by Paul himself within his fivefold scheme of salvation at Romans 8:30: foreknown, predestined, called, made righteous and glorified.
The Pacific zonal asymmetry and its influence on Southern Hemisphere sea ice variability
Authors: Hobbs W.R. , Raphael M.N. 
Published: July 2010

AbstractAt monthly and annual timescales, the zonally asymmetric circulation over the Southern Ocean is dominated by two quasi-stationary anticyclones: a western anticyclone approximately located south of New Zealand, and an eastern anticyclone located over the Drake Passage region. In this research their influence on late 20th century Antarctic sea ice is explored. During early winter, sea ice in the Weddell, Amundsen and Bellingshausen seas is influenced by the location of the east anticyclone. During late winter, the strength and location of the west anticyclone influences sea ice primarily in the Ross and Amundsen seas. The anticyclones have some effect on wind-driven sea ice motion, but the primary mechanism explaining their link to sea ice appears to be meridional atmospheric thermal advection. A western shift in the west anticyclone may be partly responsible for observed increases in ice cover in the Ross Sea over the late 20th century, but there is little evidence in existing data to support a link between the east anticyclone and observed sea ice trends.
Perspectives on influenza evolution and the role of research
Authors: Forrest Heather L. , Webster Robert G. 
Published: July 2010

AbstractInfluenza is a highly contagious respiratory pathogen that continues to evolve and threaten both veterinary and human public health. Influenza A viruses are continually undergoing molecular changes through mutations, reassortment, and, in rare instances, recombination. While they generally cause benign enteric infection in their natural reservoir of wild aquatic birds, they can cause catastrophic and potentially lethal disease outbreaks in humans, domestic poultry, and pigs when they cross the host species barrier. The continuing circulation of highly pathogenic (HP) H5N1 influenza viruses in domestic poultry in parts of Eurasia and the emergence and global spread of pandemic H1N1 2009 are current examples of influenza evolution. The spread of both HP H5N1 and pandemic H1N1 to multiple hosts emphasizes the potential for continued evolution. In this review, we discuss the current understanding of influenza A virus structure and strategies of variation, with a specific focus on the HP H5N1 and pandemic H1N1 influenza viruses. Additionally, we attempt to identify the gaps in our knowledge of H5N1 and pandemic H1N1 influenza viruses. These gaps include (i) an understanding of the molecular determinants of influenza virus and the host that permit efficient transmissibility and pandemic potential, (ii) the urgent need for prospective surveillance in apparently healthy swine, (iii) the molecular determinants of high pathogenicity in poultry, pigs, and people, (iv) the genetic basis of host susceptibility, (v) antigenic variability, (vi) the use of vaccine to control influenza, (vii) the role of wild birds as the reservoir of highly pathogenic avian influenza, (viii) the problems with vaccines, (ix) seasonality, (x) co-infections, and (xi) anti-influenza drug resistance. Our failure to eradicate HP H5N1 globally and to explain why H5N1 does not transmit efficiently in humans while an H1N1 pandemic virus of swine origin spread globally in months are key examples that emphasize the critical need to bridge these knowledge gaps. Future directions in influenza research that will help us resolve each of the above-mentioned knowledge gaps include complete genomic and proteomic analysis of both the virus and the host with the prospect of designing new control strategies and the development of genetically resistant hosts.
Avian influenza: our current understanding
Authors: Suarez David L. 
Published: July 2010

AbstractAvian influenza (AI) virus is one of the most important diseases of the poultry industry around the world. The virus has a broad host range in birds and mammals, although the natural reservoir is wild birds where it typically causes an asymptomatic to mild infection. The virus in poultry can cause a range of clinical diseases and is defined either as low pathogenic AI (LPAI) or highly pathogenic AI (HPAI) depending on the type of disease it causes in chickens. Viruses that replicate primarily on mucosal surfaces and cause mild disease with low mortality are termed LPAI. Viruses that replicate on mucosal surfaces and systemically and cause severe disease with a mortality rate of 75% or greater in experimentally infected chickens are referred to as HPAI. A virus that is highly pathogenic in chickens may infect but result in a completely different disease and replication pattern in other host species. Outbreaks of HPAI have been relatively uncommon around the world in the last 50 years and have had limited spread within a country or region with one major exception, Asian lineage H5N1 that was first identified in 1996. This lineage of virus has spread to over 60 countries and has become endemic in poultry in at least four countries. AI virus also represents a public health threat, with some infected humans having severe disease and with a high case fatality rate. AI remains a difficult disease to control because of the highly infectious nature of the virus and the interface of domestic and wild animals. A better understanding of the disease and its transmission is important for control.
Interspecies and intraspecies transmission of influenza A viruses: viral, host and environmental factors

Published: July 2010

AbstractInfluenza A viruses are enveloped viruses belonging to the familyOrthomyxoviridaethat encompasses four more genera: Influenza B, Influenza C, Isavirus and Thogotovirus. Type A viruses belong to the only genus that is highly infectious to a variety of mammalian and avian species. They are divided into subtypes based on two surface glycoproteins, the hemagglutinin (HA) and neuraminidase (NA). So far, 16 HA and 9 NA subtypes have been identified worldwide, making a possible combination of 144 subtypes between both proteins. Generally, individual viruses are host-specific, however, interspecies transmission of influenza A viruses is not uncommon. All of the HA and NA subtypes have been isolated from wild birds; however, infections in humans and other mammalian species are limited to a few subtypes. The replication of individual influenza A virus in a specific host is dependent on many factors including, viral proteins, host system and environmental conditions. In this review, the key findings that contribute to the transmission of influenza A viruses amongst different species are summarized.
New class of SiGe reduced-size loaded slow wave 60 GHz CPW series/shunt stubs and its applications to the design of slow wave bandpass filters
Authors: Hettak Khelifa , Morin Gilbert A. , Stubbs Malcolm G. 
Published: July 2010

This paper proposes a practical approach for developing a new class of compact slow-wave coplanar waveguide (CPW) series/shunt stubs, which offer 40% reduction in size relative to a conventional design. It demonstrates that the technique using interdigitated capacitive loading can provide size and cost reductions, while also providing performance enhancements such as better return loss. The experimental prototypes presented in this paper demonstrate the validity of the design method and the ability to print interdigitated capacitors inside the center conductor of the series/shunt stubs. The principle of achieving such high-quality circuits is detailed and is also confirmed by theoretical and experimental results, which are in reasonable agreement up to at least 70 GHz. The paper also presents a family of novel topologies of slow wave bandpass filters based on the proposed capacitively loaded CPW series/shunt stubs.
Biological knowledge bases using Wikis: combining the flexibility of Wikis with the structure of databases

Published: July 2010

Abstract
Summary: In recent years, the number of knowledge bases developed using Wiki technology has exploded. Unfortunately, next to their numerous advantages, classical Wikis present a critical limitation: the invaluable knowledge they gather is represented as free text, which hinders their computational exploitation. This is in sharp contrast with the current practice for biological databases where the data is made available in a structured way. Here, we present WikiOpener an extension for the classical MediaWiki engine that augments Wiki pages by allowing on-the-fly querying and formatting resources external to the Wiki. Those resources may provide data extracted from databases or DAS tracks, or even results returned by local or remote bioinformatics analysis tools. This also implies that structured data can be edited via dedicated forms. Hence, this generic resource combines the structure of biological databases with the flexibility of collaborative Wikis.

Abstract
Priede, I. G., Godbold, J. A., Niedzielski, T., Collins, M. A., Bailey, D. M., Gordon, J. D. M., and Zuur, A. F. 2011. A review of the spatial extent of fishery effects and species vulnerability of the deep-sea demersal fish assemblage of the Porcupine Seabight, Northeast Atlantic Ocean (ICES Subarea VII). – ICES Journal of Marine Science, 68: 281–289. We review information from scientific trawl surveys carried out between 1977 and 2002 in the Porcupine Seabight and Abyssal Plain area of the Northeast Atlantic (240–4865 m water depth). Since the late 1980s, commercial bottom-trawl fisheries targeting mainly roundnose grenadier (Coryphaenoides rupestris), black scabbardfish (Aphanopus carbo), and orange roughy (Hoplostethus atlanticus) have been operating at depths of 500–1500 m, intersecting the depth ranges of 77 demersal fish species that would therefore be vulnerable to fishery effects. Comparisons of trawls pre-1989 and post-1997 indicate a significant decrease in total abundance of demersal fish down to 2500 m. Detailed analyses of the 15 most-abundant species showed that nine species with depth ranges within the commercial fishing depth have decreased in abundance. Other species were either not affected (Bathypterois dubius) or only affected at the shallow end of their range (Coryphaenoides guentheri). Species with a minimum depth of occurrence &gt;1500 m (Coryphaenoides armatus and Coryphaenoides leptolepis) increased in abundance over part of their depth range. Decreases in abundance are probably caused by commercial fishing activities, an effect that is transmitted downslope by removal of fish at the shallow end of their depth range, resulting in declines at the deeper end of the depth range. The estimated fishery area is ca. 52 000 km2, but the potential impact probably extends to ca. 142 000 km2 and to many non-target species.
Mining seafloor massive sulphides and biodiversity: what is at risk?

Abstract
Van Dover, C. L. 2011. Mining seafloor massive sulphides and biodiversity: what is at risk? – ICES Journal of Marine Science, 68: 341–348. Scientific exploration of the deep sea in the late 1970s led to the discovery of seafloor massive sulphides at hydrothermal vents. More recently, sulphide deposits containing high grades of ore have been discovered in the southwest Pacific. In addition to metal-rich ores, hydrothermal vents host ecosystems based on microbial chemoautotrophic primary production, with endemic invertebrate species adapted in special ways to the vent environment. Although there has been considerable effort to study the biology and ecology of vent systems in the decades since these systems were first discovered, there has been limited attention paid to conservation issues. Three priority recommendations for conservation science at hydrothermal vent settings are identified here: (i) determine the natural conservation units for key species with differing life histories; (ii) identify a set of first principles for the design of preservation reference areas and conservation areas; (iii) develop and test methods for effective mitigation and restoration to enhance the recovery of biodiversity in sulphide systems that may be subject to open-cut mining.
