Interactive effects of losing key grazers and ecosystem engineers vary with environmental context
No full textLoss of biodiversity may cause significant changes to ecosystem structure and functioning. Evidence from long-term in situ removal experiments is rare but important in determining the effects of biodiversity loss against a background of environmental variation. Limpets and mussels are thought to be important in controlling community structure on wave-exposed shores in the UK: limpets as key grazers, mussels as ecosystem engineers. A long-term factorial removal experiment revealed interactive effects that varied between 2 shores in SW England. At one site (Harlyn), removing limpets caused a significant shift in community structure, but where limpets were lost, the presence or absence of mussels made little difference. Where limpets were present, however, the removal of mussels changed the structure and variability of the community. At the other site (Polzeath), the loss of mussels caused significant changes in community structure, and limpets played a less important role. At Harlyn, fucoid algae were abundant throughout the year. There were fewer algae at Polzeath, and cover was dominated by the summer bloom of ephemerals. At Harlyn, the limpets played a major role in controlling algae, but their effects were mediated by the presence of mussels. Other grazers were not able to fulfil their role. At Polzeath, mussels were far more important, and ephemeral algae grew on them regardless of the presence or loss of limpets. These findings emphasise the need to assess spatial and temporal variation in the effects of biodiversity loss and the importance of interactive effects of loss of multiple species from different functional groups

Temporal patterns of inflammatory gene expression in local tissues after banding or burdizzo castration in cattle
No full textpeer-reviewedBackground: Castration of male cattle has been shown to elicit inflammatory reactions and acute inflammation is initiated and sustained by the participation of cytokines. Methods: Sixty continental × beef bulls (Mean age 12 ± (s.e.) 0.2 months; Mean weight 341 ± (s.e.) 3.0 kg) were blocked by weight and randomly assigned to one of three treatments (n = 20 animals per treatment): 1) untreated control (Con); 2) banding castration at 0 min (Band); 3) Burdizzo castration at 0 min (Burd). Samples of the testis, epididymis and scrotal skin were collected surgically from 5 animals from each group at 12 h, 24 h, 7 d, and 14 d post-treatment, and analysed using real-time PCR. A repeated measurement analysis (Proc GLM) was performed using SAS. If there was no treatment and time interaction, main effects of treatment by time were tested by ANOVA. Results: Electrophoresis data showed that by 7 d post-castration RNA isolated from all the testicle samples of the Burd castrated animals, the epididymis and middle scrotum samples from Band castrates were degraded. Transitory effects were observed in the gene expression of IFN-γ, IL-6, IL-8 and TNF-α at 12 h and 24 h post treatment. Burd castrates had greater (P < 0.05) testicular IFN-γ mRNA levels compared with Band and Con animals, but lower (P < 0.05) testicular TNF-α mRNA levels compared with Con animals. Band castrates had greater (P < 0.05) testicular IL-6 mRNA levels than Burd castrates at 12 h post-castration. Burd castrates had greater (P < 0.05) testicular IL-8 mRNA levels than Band and Con animals at 24 h post-castration. In the epididymis, Burd castrates had greater (P < 0.05) IL-6 mRNA (both at 12 h and 24 h post treatment) and IL-8 mRNA (12 h post treatment) levels compared with Band and Con animals; Burd castrates had greater (P = 0.049) IL-10 mRNA levels than Band castrates at 12 h post-castration. Conclusion: Banding castration caused more inflammatory associated gene expression changes to the epididymis and scrotum than burdizzo. Burdizzo caused more severe acute inflammatory responses, in terms of pro-inflammatory cytokine gene expression, in the testis and epididymis than banding
Taxonomy, phylogenetic and biogeographical relationships of African grassland Francolins (Genus: Scleroptila)
No full textBibliography: leaves 23-28.The potential for using a combination of molecular and whole-organismal data has opened up new avenues for avian taxonomy, phylogenetics and biogeography. Such a multifaceted approach is used here to identify diagnosable taxa within the Orange River Francolin Scleroptila levaillanloides species complex and resolve evolutionary relationships between these taxa and other mono-and polytypic forms within the Red-winged Group of francolins (= genus Scleroplila sensli lalo). Mitochondrial cytochrome-b DNA sequence data (±250 b.p.) from 50 individuals and 19 morphological characters extracted from reports in published literature were employed to achieve these aims. These characters were analysed separately and also in combination using maximum parsimony (DNA sequences and organismal data), maximum likelihood (DNA sequences) and distance (DNA sequences) analyses. Monophyly of the Red-winged Group plus the Ring-necked Francolin Dendroperdix slreptophorus was supported by all the analyses (bootstrap support ranged from 50%-94%) except distance analysis. The Orange River Francolin complex was found to be non-monophyletic. Two distinct clades were identified, one comprising taxa from southwestern and the other from northeastern Africa. Morphological analysis yielded a distinct clade of the southwestern Orange River Francolin. The other polytypic species and assemblages thereof show poor resolution. The results of this study clearly demonstrate a need for further assessment of the taxonomic status of Scleroptila spp. and their phylogenetic relationships

No full textQuality practices, priorities and performance: An international study
No full textThis paper presents the results of a survey administered across seventeen countries that seeks to examine quality practices, priorities and performance. The participating countries were Argentina, Australia, Belgium, Brazil, China, Croatia, Denmark, Germany, Hungary, Ireland, Italy, Netherlands, Norway, Spain, Sweden, UK and USA. The methodology involved the use of a self-administered questionnaire to director/head of operations/manufacturing in best practice firms within the sector of firms classified by ISIC(rev.2) Division 38. There is evidence of both similarities and differences across the countries studied. Further analysis is required to explore the convergence versus “culture specific” argument

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
The obedient son: Deuteronomy and christology in the gospel of Matthew
No full textThis study argues that sonship and obedience are prominent and related themes
in the Gospel of Matthew, and the Evangelist's christological articulation of obedient
sonship is drawn from the calling of Israel to be Yahweh's obedient son in
Deuteronomy. Thus, it is argued that a consideration of Israel's scriptural traditions
is necessary to understand most fully Matthew's teaching of the sonship of Jesus.Chapter 1 explores Matthew's use of the OT and, building on the work of
Richard Hays, outlines a method for identifying subtle intertextual allusions, and
suggests a composition criticism approach to Matthew that focuses on the gospel as a
literary and redactional whole.Chapter 2 seeks to establish the historical plausibility for the claim that
Matthew was heavily indebted to Deuteronomy by tracing the circulation and use of
Deuteronomy in general in ancient Jewish and Christian literature. The purpose of
this chapter is to provide a foundation for the claim that Deuteronomy would likely
have been an important text for Matthew.Chapter 3 then focuses on Deuteronomy, tracing the covenantal context for the
themes of sonship and obedience. It is argued that the sonship of Israel is a key motif
in Deuteronomy, and this sonship was predicated on obedience. Key texts include
Deut 1; 8; 14; 21; 32, and the themes of love, election, and inheritance are also
considered.Chapter 4 traces the influence of Deuteronomy under the specific rubric of
obedient sonship through ancient Jewish and Christian literature, including texts
which Matthew may have known. Here it is argued that obedient sonship, in
association with Deuteronomic themes, is prominent in a wide range of texts.Chapters 5-7 focus specifically on Matthew. It is argued in chapter 5 that the
Temptation Narrative (Matt 4.1-11), the Sermon on the Mount (Matt 5-7), and the
accusation that Jesus was a glutton and a drunkard (Matt 11.16-19) all demonstrate
rather strong resonances with Deuteronomy and the Deuteronomic call to obedient
sonship. Chapter 6 proposes two significant possibilities: that the baptism of Jesus
(Matt 3.13-17) and the Transfiguration (Matt 17.1-21) may also be influenced by the
Deuteronomic perspective on sonship. Finally, chapter 7 suggests three additional
clusters of texts that may also indicate Deuteronomy's filial influence on Matthew:
Matt 1.20; 12.46-50; 21.28-22.14.1.20; 12.46-50; 21.28-22.14.
Chapter 8 offers a conclusion and synthesis, arguing that chapters 1-4 provide
the foundation for the claims in chapters 5-7. It is concluded that the Deuteronomic
teaching of obedient sonship was quite pervasive in the ancient world, and there is an
historically plausible case to be made that Matthew was influenced by this tradition.
However, it is also argued that Matthew has appropriated the Deuteronomic concept
of obedient sonship in unique ways, applying it messianically to the person of Jesus
as the New Israel, and consequently also to the disciples of Jesus, who are able to be
a part of God's family through Jesus, the preeminently obedient son
