Published: December 2017

AbstractBody mass is a key trait constraining interspecific interactions in food webs through changes in metabolic requirements. Because climate warming affects metabolic rates, it creates direct selective effects on body mass. Many empirical studies suggest that body mass decreases under warming, although important exceptions have been noted. We first analyze the evolution of body mass in a simple consumer-resource model to provide conditions under which a body mass increase or decrease may be expected. We then extend our model to a multi-trophic food web context that allows for the coevolution of body mass and of feeding preferences. We focus here on how the trophic position of a consumer influences its evolutionary response to warming under different scenarios for the temperature dependence of attack rates. We observe that body masses can remain constant or increase with temperature when attack rates are constant or increasing with temperature, while body mass reductions in response to warming are only expected when attack rates have a thermal optimum and populations are initially locally adapted. We also found that body masses at lower trophic levels vary less under warming than body masses at higher trophic levels, which may be explained by decreasing levels of stabilizing selection along food chains.

AbstractIn breast cancer cells, topologically associating domains (TADs) behave as units of hormonal gene regulation with transcripts within hormone responsive TADs changing coordinately their expression in response to steroid hormones. Here we further described that responsive TADs contain 20-100 kb-long clusters of intermingled estrogen receptor (ER) and progesterone receptor (PR) binding sites, hereafter called Hormone-Control Regions (HCRs). We identified more than 200 HCRs, which are frequently bound by ER and PR even in the absence of hormones. These HCRs establish steady long-distance inter-TAD interactions between them and organize characteristic looping structures with promoters even in the absence of hormones. This organization is dependent on the expression of the receptors and is further dynamically modulated in response to steroid hormones. HCRs function as platforms integrating different signals resulting in some cases in opposite transcriptional responses to estrogens or progestins. Altogether, these results suggest that steroid hormone receptors act not only as hormone-regulated sequence-specific transcription factors, but also as local and global genome organizers.HighlightsHormone responsive TADs are organized around conserved large regulatory
regions (HCRs) enriched in ER and PR.HCR contact promoters within their TADs and engaged long-range inter-TADs
contacts between them.Binding of the receptors in absence of hormones maintains global HCR-HCR
interactions and intra-TADs regulatory loops.HCRs can integrate the hormone signals in divergent ways leading to opposite
restructuration of TADs in response to Estrogens or Progestins.
A temperature dependent trophic cascade modifies temperature dependence of ecosystem function

Published: December 2017

AbstractEcological communities and their ecosystem functions are sensitive to temperature, and aquatic habitats worldwide continue to experience unprecedented warming. Understanding ecological effects of warming requires linking empirical evidence to theories that allow projection to unobserved conditions. Metabolic scaling theory and its tests suggest that warming accelerates ecosystem functions (e.g., oxygen flux), yet this prediction apparently contradicts community-level studies suggesting warming is a stressor that can reduce ecosystem function. We sought to reconcile these predictions with an experimental test of the hypothesis that cascading trophic interactions modify the temperature-dependence of community structure and ecosystem fluxes. In a series of independent freshwater ecosystems exposed to a thermal gradient, we found that warmer temperatures strengthened the trophic cascade increased and indirectly changed community structure by altering grazer species composition and phytoplankton biomass. Temperature-driven community shifts only modestly affected the temperature dependence of net ecosystem oxygen fluxes. Over the 10 °C thermal gradient, NPP and ER increased ∼2.7-fold among ecosystems, while standing phytoplankton biomass declined by 85-95%. The exponential increase in oxygen flux over the thermal gradient, as well as monotonic declines in phytoplankton standing stock, suggested no threshold effects of warming across systems. We also observed temperature variation over time, within ecosystems. For phytoplankton biomass, temporal variation had the opposite effect to spatial variation, suggesting that within-community temporal change in community structure was not predicted by space-for-time substitution. We conclude that food chain length can modify effects of temperature on ecosystem fluxes, but that temperature can still have continuous and positive effects on ecosystem fluxes, consistent with patterns based on large-scale, macroecological comparisons. Changes in community structure, including temperature dependent trophic cascades, may be compatible with prevailing and predictable effects of temperature on ecosystem functions related to fundamental effects of temperature on metabolism.Statement of authorshipJG & MIO designed the study, MIO & US provided materials, JG & SJC performed research and collected data, JG performed zooplankton analysis, SJC performed phytoplankton analysis, JG & MIO performed modeling work, analyzed data output, and wrote the first draft, and all authors contributed substantially to reviews
A new method to isolate algal species from mix algal culture
Authors: Ali Ehsan , Mirza Saima S. 
Published: December 2017

AbstractTo meet the issues of energy and environment, algae cultivation for biofuel and CO2sequestration is getting popular at the global level. Specific algal strains have been identified for production of biofuel, biomolecules and biomass. To start algae cultivation at lab or industrial scale, it is requirement to have isolated and identified algal culture for targeted products. Water sample for algae from aquatic system is usually consist of mix culture of algae and need to be processed for targeted isolated algal strains using reported techniques like streaking, spraying, serial dilution, and single-cell isolations. But none of these techniques is considered as efficient or popular except streaking on agar plate which involves a set of microbial techniques and may take months to make isolation properly. Here, a new method is proposed to make alginic acid solution using aquatic sample followed by pouring it in calcium chloride solution drop by drop which makes the beads with single or more algal species trapped in each bead. The trapped algal species in the beads are grown in 96 wells plate having single bead in each well with standard medium leading to microscopic verification of the isolated algal species to process further. A mix culture from a lake was subjected to isolation using proposed method and excellent results were obtained in one week duration.
Gene networks underlying faster flowering induction in response to far-red light

Published: December 2017

ABSTRACTLight is one of the main signals that regulates flowering. Low red to far-red ratios accelerate flowering in a wide range of species. The central gene pathways controlling flowering time in Arabidopsis, appear to be largely conserved in legumes. However, numerous examples exist of gene duplication and loss. The role ofCONSTANS-LIKEgenes as integrators of the photoperiod response has been questioned in several dicot species, including legumes. In this study on subterranean clover, using RNA-seq and controlled light spectra, we identified 13 differentially expressed genes related to light signalling, meristem identity and flowering promotion. Of these, we pinpointed genes which seem to link photoperiod and far-red light signalling coding for a With no lysine kinase, a CCT motif related toCONSTANS, aFLOWERING LOCUS T b2like protein, and their active downstream cascade. The earlier down-regulation of these genes under blue compared to far-red-enriched light may explain their role in floral induction. A second independent approach (qPCR analysis) confirmed our findings. Contrasting responses to light quality related to reproduction and defence mechanisms were also found. These results will contribute to a better understanding of the molecular basis of flowering in response to light quality in long-day plants.

AbstractMenopause is associated with cognitive decline, and hormone therapies (HT) can improve cognition dependent on time since menopause. Previous parity also influences cognition in later life. The present study investigated how primiparity and long-term ovariectomy influence cognition, hippocampal neurogenesis, and neuronal activation in middle-aged rats in response to the HT, Premarin. Nulliparous and primiparous rats were sham-ovariectomized or ovariectomized, administered vehicle or Premarin six months later, and trained in the Morris water maze. Premarin improved spatial learning and memory in nulliparous rats, but impaired spatial and reversal learning in primiparous rats. Primiparity increased hippocampal neurogenesis, whereas Premarin treatment decreased immature neurons in both primiparous and nulliparous middle-aged rats in a region-specific manner. Moreover, Premarin increased serum TNFα and KC/GRO in nulliparous, but not primiparous, rats, whereas Premarin increased zif268 expression in the CA3 region of the hippocampus in primiparous rats. Thus, primiparity alters how Premarin affects spatial learning, neuronal activation, serum cytokines, and adrenal mass. These findings have implications for the tailored treatment of age-associated cognitive decline in women.
Host_microbe_mapper allows to analyse and interpret the expression of dual RNA-seq measurements and reveals potential microbial contaminations in the data
Authors: Nussbaumer Thomas 
Published: December 2017

AbstractNext-generation sequencing technologies provide a wealth of sequencing data. To handle these data amounts, various tools were developed over the last years for mapping, normalisation and functional analyses. To support researchers in the interpretation of expression measurements originating from dual RNA-seq studies and from host-microbe systems in particular, the computational pipeline host_microbe_mapper can be applied to quantify and interpret dual RNA-seq datasets in host-microbe experiments. The pipeline with all the required scripts is stored at the Github repository (https://github.com/nthomasCUBE/hostmicrobemapper).
Genetic dissection of cyclic pyranopterin monophosphate biosynthesis in plant mitochondria
Authors: Kruse Inga , Maclean Andrew , Hill Lionel , Balk Janneke 
Published: December 2017

AbstractMitochondria play a key role in the biosynthesis of two metal cofactors, iron-sulfur (FeS) clusters and molybdenum cofactor (Moco). The two pathways intersect at several points, but a scarcity of mutants has hindered studies to better understand these links. We screened a collection of sirtinol-resistant Arabidopsis thaliana mutants for lines with decreased activities of cytosolic FeS enzymes and Moco enzymes. We identified a new mutant allele of ATM3, encoding the ATP-binding cassette Transporter of the Mitochondria 3 (systematic name ABCB25), confirming the previously reported role of ATM3 in both FeS cluster and Moco biosynthesis. We also identified a mutant allele in CNX2, Cofactor of Nitrate reductase and Xanthine dehydrogenase 2, encoding GTP 3′,8-cyclase, the first step in Moco biosynthesis which is localized in the mitochondria. A single nucleotide polymorphism in cnx2-2 leads to substitution of Arg88 with Gln in the N-terminal FeS cluster-binding motif. cnx2-2 plants are small and chlorotic, with severely decreased Moco enzyme activities, but they performed better than a cnx2-1 knockout mutant, which could only survive with ammonia as nitrogen source. Measurement of cyclic pyranopterin monophosphate (cPMP) levels by LC-MS/MS showed that this Moco intermediate was below the limit of detection in both cnx2-1 and cnx2-2, and accumulated more than 10-fold in seedlings mutated in the downstream gene CNX5. Interestingly, atm3-1 mutants had less cPMP than wild type, correlating with previous reports of a similar decrease in nitrate reductase activity. Taken together, our data functionally characterise CNX2 and suggest that ATM3 is indirectly required for cPMP synthesis.
40-year reform of farmland institution in China: target, effort and the future
Authors: Luo Biliang 
Published: December 2017

Purpose
Based on the brief historical review, the purpose of this paper is to expound the target and bottom line for the farmland institutional reform of in China, analyze the “Chinese scenes” and historical heritage of farmland institutional arrangement, evaluate the policies and their effects over the last four decades and outline the keynotes and possible direction of the future reform.

Design/methodology/approach
The paper builds the analytical clue of “institutional target – institutional heritage – policy effort – realistic dilemma – future direction” and review and forecast the Chinese farmland institutional reform.

Findings
The farmland institution is an important issue with Chinese characteristics. Over the last four decades, the farmland institutional reform in China has focused on “stabilizing the land property rights” and “promote the farmland transfer.” As the study indicates, the promotion of farmland transfer has not effectively improved the scale economy of agriculture and stabilizing land property rights by titling may restrain the development of farmland transfer market because farmland transfer is of special market logic.

Originality/value
It depends on the revitalization of farmland management rights to resolve the transaction constraint of personal property and its endowment effect in farmland transfer. And, classifying the land management property to involve farmers into the economy of division can be reference for the reform of traditional agriculture worldwide.
Corporate governance and management incentives: evidence from the Scandinavian countries
Authors: Xia Belle Selene , De Beelde Ignace 
Published: December 2017

Purpose
The Scandinavian boards are known for their “best practices” for corporate governance. This paper aims to examine the management incentives behind corporate disclosure via an empirical study.

Design/methodology/approach
Many of the previous empirical work have focused on the US data, but the generalizability of such findings is geographically bounded. The set of management incentives in this paper is examined using a total sample of 123 local annual reports via some of the largest publicly listed firms in the Scandinavian countries between the years 2008-2012.

Findings
The findings of this study reveal that a firm’s financial success originates from the different attributes of corporate governance. Correlation and regression analyses reveal that in terms of firm size, leverage ratio, the existence of audit committee and the independence of CEO, there is a correlation between firm-specific factors and the level of disclosure. In contrast to the previous literature, a positive relationship between corporate disclosure and information asymmetry was not found.

Originality/value
The results of this study are valuable to the policymakers when implementing regulations on corporate governance control. The strategic implications of the findings on business decisions and future research are also discussed.
Barriers to use open government data in private sector and NGOs in Pakistan
Authors: Saxena Stuti , Muhammad Irfan 
Published: December 2017

Purpose
Open government data (OGD) is making available data freely to all by the government with the aim to ensure accountability and transparency in government besides generating public value by its usage. OGD is an emerging government initiative in Pakistan, and there is a lot of potential for harnessing OGD for spearheading innovation and improvising services in different economic sectors. This paper aims to seek to investigate the usage of OGD in private sector and non-governmental organizations (NGOs) in Pakistan.

Design/methodology/approach
Documentary analysis is conducted to review the national OGD portal of Pakistan. Besides, structured interviews were conducted with 49 senior management representatives from private sector and NGOs to solicit their perspectives regarding the usage of OGD for professional purposes. Also, questions were posed regarding the challenges in harnessing OGD for professional purposes.

Findings
OGD has immense usage for private sector and NGOs; however, more initiatives are required on the part of the government to open their data sets. Further, involvement of stakeholders from the private sector and NGOs and other interested partners is required for an optimum usage of OGD in different economic sectors of Pakistan.

Research limitations/implications
As the research focuses on private sector and NGOs in Pakistan, the study requires a more broad-based approach to take into account the perspectives of different users. Further research is required to appreciate the role of contextual factors in determining the usage of OGD in Pakistan.

Practical implications
Government should be more forthcoming in its OGD initiatives and encourage collaboration from citizens, businesses, voluntary organizations and the like.

Social implications
Working professionals from different economic sectors should tap OGD for generating value by improvising their services.

Originality/value
The study is the first one to be conducted in Pakistan about the OGD initiatives of the country. Soliciting views from the key management representatives in the private sector and NGOs, the paper contributed to the extant OGD literature which is more supply-focused and not demand-driven. While conceding that there are ample usages of OGD for the different economic sectors, the paper underlines the need for refining the OGD initiatives of Pakistan.
Guidelines for authors in Croatian scholarly journals
Authors: Hebrang Grgić Ivana , Čačković Lorena 
Published: December 2017

Purpose
This paper aims to compare guidelines for authors in Croatian scholarly journals regarding six scientific fields (according to Croatian classification) and to show the representation of technical and ethical issues that are explained in guidelines for authors.

Design/methodology/approach
The aim of the research is to identify elements that are included in guidelines for authors in Croatian scholarly journals from all scientific fields. Fourteen parameters for 200 journals were analyzed (all the journals that had published at least one 2016 issue by the end of February 2017).

Findings
The parameter that is explained in the most journals is the length of the manuscript (91.5 per cent). The lowest number of journals explains Open Researcher and Contributor ID (1.5 per cent). The highest percentage of journals that explain plagiarism is in the field of natural sciences (44 per cent). As compared to the results of previous researches, there is an increase in the number of ethical questions mentioned in the guidelines for authors of Croatian scholarly journals.

Practical implications
This paper provides recommendations and suggestions that could help journal editors make guidelines for authors more informative. That could help in advancing editorial process (e.g. peer review process) and in avoiding misconducts (e.g. plagiarism or false attribution of authorship).

Originality/value
This paper is the first detailed content analysis of guidelines for authors in all Croatian scholarly journals.

Authors: Croucher Stephen Michael , Kelly Stephanie , Condon Shawn Michael , Campbell Elsa , Galy-Badenas Flora , Rahmani Diyako , Zeng Cheng , Nshom Elvis 
Published: December 2017

Purpose
This study aims to first explore the extent to which argumentativeness changed during the adaptation process among Muslim immigrants to France from 2006 to 2015 and, second, to examine the cultural fusion process. The study investigates the influence of intercultural contact on communication traits by exploring the extent to which members of the dominant cultural group adapt their argumentativeness over time.

Design/methodology/approach
Through a longitudinal panel study, the paper investigates the influence of intercultural contact on communication traits by exploring the extent to which members of the dominant cultural group adapt their argumentativeness over time. Confirmatory factor analysis and structural equation modeling are used to assess the hypotheses and research question.

Findings
Results revealed a curvilinear relationship between argumentativeness and time. Argumentativeness increased from 2006 to 2009, remained constant from 2009 to 2012 and then decreased after 2012. Furthermore, data analysis revealed argumentativeness levels among members of the dominant culture did not change.

Research limitations/implications
The results are potentially limited by the sample being a convenience sample and the presence of extenuating factors.

Originality/value
Argumentativeness is viewed by many researchers as a functional form of communication. However, few studies have longitudinally studied how this trait can change over time.
Predicting conflict acts using behavior and style measures
Authors: Davis Mark H. , Schoenfeld Michael B. , Flores Elizabeth J. 
Published: December 2017

PurposeThis paper aims to compare style and behavior-focused individual difference measures in their ability to uniquely predict naturally occurring conflict acts.Design/methodology/approachPrimary participants (and a friend of their choosing) completed a style measure and a behavior-focused measure about the primary participants and reported on the occurrence of a variety of conflict actions over a 60-day period.FindingsFor self-ratings and friend ratings, both the style measure and the behavior-focused measure were significantly related to the occurrence of conflict acts. However, the unique effect of the behavior-focused measure was stronger than that of the style measure.Research limitations/implicationsThe data were collected from college students, thus limiting the generalizability of the findings. The measure of conflict acts was based on recall, which may also be subject to error and bias. In terms of implications, the findings strongly suggest that behavior-focused instruments are superior to style measures in predicting everyday conflict acts.Practical implicationsBecause the behavior-focused individual difference measure was a better predictor of actual behavior than the style measure, investigators interested in such prediction may want to seriously consider using such measures.Originality/valueLittle research exists regarding the relative predictive abilities of style measures and behavior-focused measures; this paper provides some of the first such evidence.
