Riding the Kuroshio Current: Stepping stone dispersal of the Okinawa tree lizard across the East Asian Island Arc
Authors: Yang Shang‐Fang , Komaki Shohei , Brown Rafe M. , Lin Si‐Min 
Published: October 2017

AbstractAimLocated hundreds of kilometres offshore of continental mainland Asia, the extremely high level of land vertebrate endemism in the East Asian Island Arc provides an excellent opportunity to test hypotheses regarding biogeographic processes and speciation. In this study, we aim to test alternative explanations for lineage diversification (vicariance versus dispersal models), and further develop a temporal framework for diversification in our focal taxon, which is consistent with the known age of these islands. We achieve these tests by investigating the historical biogeography of the Okinawa tree lizard (Japalura polygonata), one of the few widely‐distributed reptiles across this archipelago.LocationThe East Asian Island Arc: (1) Central Ryukyu (Amami and Okinawa groups); (2) Southern Ryukyu (Miyako and Yaeyama groups); (3) Taiwan and adjacent islands.MethodsA total of 246 tissues were sampled from 10 localities in the Ryukyu archipelago and 17 localities in Taiwan, covering the entire distributional range of this species, including all subspecies. DNA sequences of the mitochondrial cytochrome b, 16S ribosomal RNA, nuclear BACH‐1 and RAG‐1 genes (total: 4,684 bp) were obtained from these samples. We used maximum likelihood and Bayesian methods to infer phylogeny and divergence time, and used a model‐fitting method of biogeographical inference to estimate ancestral range evolution.ResultsMultiple lines of evidence combine to identify a general pattern of dispersal‐mediated diversification northward through the archipelago, following initial dispersal from Taiwan. These included (1) a phylogenetic estimate, revealing a sequential, south‐to‐north branching pattern; (2) ancestral range estimation, inferring multiple overseas dispersals and subsequent colonization of new landmasses; and (3) a reduction in genetic variation observed in successively‐diverging lineages, decreasing from Taiwan northward, towards more remote islands. These results provide strong statistical support for an interpretation of successive bouts of dispersal via the powerful, well‐documented, south‐to‐north Kuroshio Current. Estimation of divergence times suggests that most clades in southern Ryukyu and Taiwan diverged early, giving rise to lineages that have remained isolated, and that more recently‐diverged lineages then colonized northward to subsequently occupy the landmasses of the Central Ryukyu archipelago.Main conclusionsOur general inference of biogeographic history in Japalura polygonata suggested that this species originated on Taiwan and the Yaeyama group, and arrived at its current distribution in Miyako, Okinawa, Toku and Amami islands by a series of stepping‐stone dispersals, which we report for the first time for a terrestrial vertebrate endemic to this region.
What is an ‘extant’ type specimen? Problems arising from naming mammalian species‐group taxa without preserved types
Authors: Pine Ronald H. , Gutiérrez Eliécer E. 
Published: October 2017

Abstract

The International Code of Zoological Nomenclature allows the naming of new species without a type specimen ever having been preserved. This practice causes problems and is undesirable because if related, cryptic, sibling species are encountered later, it may not be possible either to allocate them with certainty to the earlier named species, or to determine them to be something different.

We hypothesised that examination of the instances in which mammalian species were named without preserved types would reveal certain problems that are not unique to them, but are encountered more frequently than when types are preserved. We also thought the Code's stipulation that preserved types are not required in the case of specimens that are no longer ‘extant’ would present special problems hitherto unremarked upon in the literature.

We conducted a review of cases involving putative new species of mammal named since 1900. These were analysed to see what special problems they present and the frequency of such problems.

We found that the Code's waiver of the requirement that a type specimen be deposited in a collection if the specimen is no longer extant presents numerous problems—in particular, that a living‐at‐large type specimen can still be ‘extant’ even if its whereabouts are unknown at certain times and/or it may no longer be alive. Illustrations alone being used to designate type specimens is especially problematic, owing to mammals’ lack of meristic and other obvious distinguishing external characters. Hoaxes, the difficulty in determining that they are hoaxes, and various errors of taxonomic allocation appear to be especially common with names without preserved types. The Code should be revised to require preserved specimens as types for new names. Tissue samples alone for DNA analysis are not ideal for serving this purpose, but should be allowed to meet the requirement.
On the Perception of Structure
Authors: Green E. J. 
Published: October 2017

AbstractMany of the objects that we perceive have an important characteristic: When they move, they change shape. For instance, when you watch a person walk across a room, her body constantly deforms. I suggest that we exercise a type of perceptual constancy in response to changes of this sort, which I call structure constancy. In this paper I offer an account of structure constancy. I introduce the notion of compositional structure, and propose that structure constancy involves perceptually representing an object as retaining its compositional structure over time. I argue that compositional structure is represented in visual phenomenology, and I also assemble empirical evidence in support of the claim that compositional structure is recovered by the visual system. Finally, I draw out consequences of this account. I argue that structure constancy has implications for the predictive capacities of perception, and that the phenomenon places important constraints on viable accounts of both the format and reference frame of visual experience.
The effect of blue‐light blocking spectacle lenses on visual performance, macular health and the sleep‐wake cycle: a systematic review of the literature
Authors: Lawrenson John G , Hull Christopher C , Downie Laura E 
Published: October 2017

AbstractPurposeBlue‐blocking (BB) spectacle lenses, which attenuate short‐wavelength light, are being marketed to alleviate eyestrain and discomfort when using digital devices, improve sleep quality and potentially confer protection from retinal phototoxicity. The aim of this review was to investigate the relative benefits and potential harms of these lenses.MethodsWe included randomised controlled trials (RCTs), recruiting adults from the general population, which investigated the effect of BB spectacle lenses on visual performance, symptoms of eyestrain or eye fatigue, changes to macular integrity and subjective sleep quality. We searched MEDLINE, EMBASE, the Cochrane Library and clinical trial registers, until 30 April 2017. Risk of bias was assessed using the Cochrane tool.ResultsThree studies (with 136 participants) met our inclusion criteria; these had limitations in study design and/or implementation. One study compared the effect of BB lenses with clear lenses on contrast sensitivity (CS) and colour vision (CV) using a pseudo‐RCT crossover design; there was no observed difference between lens types (log CS; Mean Difference (MD) = −0.01 [−0.03, 0.01], CV total error score on 100‐hue; MD = 1.30 [−7.84, 10.44]). Another study measured critical fusion frequency (CFF), as a proxy for eye fatigue, on wearers of low and high BB lenses, pre‐ and post‐ a two‐hour computer task. There was no observed difference between low BB and standard lens groups, but there was a less negative change in CFF between the high and low BB groups (MD = 1.81 [0.57, 3.05]). Both studies compared eyestrain symptoms with Likert scales. There was no evidence of inter‐group differences for either low BB (MD = 0.00 [−0.22, 0.22]) or high BB lenses (MD = −0.05 [−0.31, 0.21]), nor evidence of a difference in the proportion of participants showing an improvement in symptoms of eyestrain or eye fatigue. One study reported a small improvement in sleep quality in people with self‐reported insomnia after wearing high compared to low‐BB lenses (MD = 0.80 [0.17, 1.43]) using a 10‐point Likert scale. A study involving normal participants found no observed difference in sleep quality. We found no studies investigating effects on macular structure or function.ConclusionsWe find a lack of high quality evidence to support using BB spectacle lenses for the general population to improve visual performance or sleep quality, alleviate eye fatigue or conserve macular health.
The advantages of intermediate‐tier, inter‐optometric referral of low risk pigmented lesions

Published: October 2017

AbstractPurposePigmented ocular lesions are commonly encountered by eye‐care professionals, and range from benign to sight or life‐threatening. After identifying a lesion, the primary care professional must establish the likely diagnosis and decide either to reassure, to monitor or to refer. The increasing use of ocular imaging technologies has contributed to an increase in the detection rate of pigmented lesions and a higher number of referrals, which may challenge existing pathways of health‐care delivery. Specialist services may be over‐burdened by referring all patients with pigmented lesions for an opinion, while inter‐optometric referrals are underutilised. The aim of this study was to describe the referral patterns of pigmented lesions to an optometry led intermediate‐tier collaborative care clinic.MethodsWe performed a retrospective review of patient records using the list of patients examined at Centre for Eye Health (CFEH) for an initial or follow up pigmented lesion assessment between the 1/7/2013 and the 30/6/2016. Analysis was performed on: patient demographic characteristics, the referrer's tentative diagnosis, CFEH diagnosis and recommended management plan.ResultsAcross 182 patient records, the primary lesion prompting referral was usually located in the posterior segment: choroidal naevus (105/182, 58%), congenital hypertrophy of the retinal pigment epithelium (CHRPE; 11/182, 6%), chorioretinal scarring (10/182, 5%) or not specified (52/182, 29%). Referrals described a specific request for ocular imaging in 25 instances (14%). The number of cases with a non‐specific diagnosis was reduced after intermediate‐tier care assessment (from 29% to 10%), while the number of diagnoses with less common conditions rose (from 2% to 21%). There was a 2% false positive referral rate to intermediate‐tier care and a first visit discharge rate of 35%. A minority required on‐referral to an ophthalmologist (22/182, 12%), either for unrelated incidental ocular findings, or suspicious choroidal naevi. Conditions most amenable to optometric follow up included: 1) chorioretinal scarring, 2) choroidal naevus, and 3) CHRPE.ConclusionsIntermediate‐tier optometric eye‐care in pigmented lesions (following opportunistic primary care screening) has the potential to reduce the number of cases with non‐specific diagnoses and to increase those with less common diagnoses. The majority of cases seen under this intermediate‐tier model required only ongoing optometric surveillance.

AbstractJust like animals, plants also contain haemoglobins (known as phytoglobins in plants). Plant phytoglobins (Pgbs) have been categorized into 6 different classes, namely, Phytogb0 (Pgb0), Phytogb1 (Pgb1), Phytogb2 (Pgb2), SymPhytogb (sPgb), Leghaemoglobin (Lb), and Phytogb3 (Pgb3). Among the 6 Phytogbs, sPgb and Lb have been functionally characterized, whereas understanding of the roles of other Pgbs is still evolving. In our present study, we have explored the function of 2 rice Pgbs (OsPgb1.1 and OsPgb1.2). OsPgb1.1, OsPgb1.2, OsPgb1.3, and OsPgb1.4 displayed increased level of transcript upon salt, drought, cold, and ABA treatment. The overexpression (OX) lines of OsPgb1.2 in Arabidopsis showed a tolerant phenotype in terms of better root growth in low potassium (K+) conditions. The expression of the known K+ gene markers such as LOX2, HAK5, and CAX3 was much higher in the OsPgb1.2 OX as compared to wild type. Furthermore, the OsPgb1.2 OX lines showed a decrease in reactive oxygen species (ROS) production and conversely an increase in the K+ content, both in root and shoot, as compared to wild type in K+ limiting condition. Our results indicated the potential involvement of OsPgb1.2 in signalling networks triggered by the nutrient deficiency stresses.

AbstractThe phytohormone abscisic acid (ABA) plays an important role in regulating plant growth, development, and adaption to various environmental stresses. Regulatory components of ABA receptors (RCARs, also known as PYR/PYLs) sense ABA and initiate ABA signalling through inhibiting the activities of protein phosphatase 2C in Arabidopsis. However, the way in which ABA receptors are regulated is not well known. A DWD protein AtRAE1 (for RNA export factor 1 in Arabidopsis), which may act as a substrate receptor of CUL4–DDB1 E3 ligase, is an interacting partner of RCAR1/PYL9. The physical interaction between RCAR1 and AtRAE1 is confirmed in vitro and in vivo. Overexpression of AtRAE1 in Arabidopsis causes reduced sensitivity of plants to ABA, whereas suppression of AtRAE1 causes increased sensitivity to ABA. Analysis of protein stability demonstrates that RCAR1 is ubiquitinated and degraded in plant cells and AtRAE1 regulates the degradation speed of RCAR1. Our findings indicate that AtRAE1 likely participates in ABA signalling through regulating the degradation of ABA receptor RCAR1.

AbstractHigh temperature (HT) decreases seed set percentage in sorghum (Sorghum bicolor [L.] Moench). The relative sensitivity of pollen and particularly pistil and the mechanistic response that induces tolerance or susceptibility to HT are not well known and hence are the major objectives of this research. The male sterile (ATx399) and fertile (RTx430) lines were exposed to 30/20 °C (optimum temperature), 36/26 °C (HT1), and 39/29 °C (HT2) from the start of booting to seed set in a controlled environment. Similarly, in the field, HT stress was imposed using heat tents. HT stress decreased pollen germination. Relatively high levels of reactive oxygen species and decreased antioxidant enzyme activity and phospholipid unsaturation were observed in pollen compared to pistil under HT. The severe cell organelle damage was observed in pollen and pistil at 36/26 and 39/29 °C, respectively. The seed set percentage was higher in HT‐stressed pistil pollinated with optimum‐temperature pollen. Direct and reciprocal crosses indicate that pollen was more sensitive with larger decreases in seed set percentage than pistil under HT stress. The negative impact was greater in pollen than pistil at lower temperatures. Overall, pollen was more sensitive than pistil to HT stress because it is more susceptible to oxidative damage than pistil.

AbstractBlue light photoreceptors, cryptochromes (CRYs), regulate multiple aspects of plant growth and development. However, our knowledge of CRYs is predominantly based on model plant Arabidopsis at early growth stage. In this study, we elucidated functions of CRY1a gene in mature tomato (Solanum lycopersicum) plants by using cry1a mutants and CRY1a‐overexpressing lines (OE‐CRY1a‐1 and OE‐CRY1a‐2). In comparison with wild‐type plants, cry1a mutants are relatively tall, accumulate low biomass, and bear more fruits, whereas OE‐CRY1a plants are short stature, and they not only flower lately but also bear less fruits. RNA‐seq, qRT‐PCR, and LC‐MS/MS analysis revealed that biosynthesis of gibberellin, cytokinin, and jasmonic acid was down‐regulated by CRY1a. Furthermore, DNA replication was drastically inhibited in leaves of OE‐CRY1a lines, but promoted in cry1a mutants with concomitant changes in the expression of cell cycle genes. However, CRY1a positively regulated levels of soluble sugars, phytofluene, phytoene, lycopene, and ß‐carotene in the fruits. The results indicate the important role of CRY1a in plant growth and have implications for molecular interventions of CRY1a aimed at improving agronomic traits.
Fluctuation in on‐again/off‐again romantic relationships: Foreboding or functional?

Published: October 2017

AbstractThis study explored how fluctuations in satisfaction and perceived partner commitment were associated with stability measures (e.g., commitment, perceived stability, relational uncertainty, turbulence) in both on‐again/off‐again and noncyclical relationships. Participants completed an initial survey, 8 weekly surveys, and a final survey. Results suggest fluctuation in perceived partner commitment across the weekly surveys was associated with all measures of stability when moderated by relationship type; fluctuation was negatively associated with the stability measures for noncyclical relationships but positively for on–off relationships. For fluctuation in satisfaction, this same pattern was found for commitment only. Overall, fluctuation, particularly in perceived partner commitment, was not viewed as disruptive for on–off partners; rather, fluctuation appeared to foster more steady and viable views of the relationship.
Authoritarian but responsive:Local regulation of industrial energy efficiency inJiangsu,China
Authors: Zhu Junming , Chertow Marian R. 
Published: October 2017

AbstractRegulatory behavior and effectiveness in authoritarian settings are subject to alternative characterizations. By tracing enforcement processes through a variety of case studies, this article proposes and refines a new model, at least with respect to energy efficiency regulations in China:authoritarian but responsive.Local rulemaking and operationalization is authoritarian, with strong and coordinative bodies of regulation, strategic plans, and active involvement of local authorities. Local authorities, however, often find themselves facing a welter of laws imposed on companies that create competing priorities for these local officials who then must struggle to find pragmatic solutions. On numerous occasions, such satisficing behavior by local officials makes them responsive to the performance and demands of regulated firms. Embedded in the decentralized authoritarian context, theauthoritarian but responsiveapproach is found to be a rational choice of local governments and different from previous conceptualizations. It helps local governments coordinate across a diverse array of regulatory issues. Drawing on environmental enforcement in China, the model provides consistent explanations for the seemingly changing and discretionary enforcement incidents.
Experimentalism in transnational forest governance: Implementing European Union Forest Law Enforcement, Governance and Trade (FLEGT) Voluntary Partnership Agreements in Indonesia and Ghana
Authors: Overdevest Christine , Zeitlin Jonathan 
Published: October 2017

AbstractOver the past decade, the European Union (EU) has created a novel experimentalist architecture for transnational forest governance: the Forest Law Enforcement, Governance and Trade (FLEGT) initiative. This innovative architecture comprises extensive participation by civil society stakeholders in establishing and revising open‐ended framework goals (Voluntary Partnership Agreements [VPAs] with developing countries aimed at promoting sustainable forest governance and preventing illegal logging) and metrics for assessing progress toward them (legality standards and indicators) through monitoring and review of local implementation, underpinned by a penalty default mechanism to sanction non‐cooperation (the EU Timber Regulation that prohibits operators from placing illegally harvested wood on the European market). This paper analyzes the implementation of VPAs in Indonesia and Ghana, the two countries furthest advanced toward issuing FLEGT export licences. A central finding is the reciprocal relationship between the experimentalist architecture of the FLEGT initiative and transnational civil society activism, whereby the VPAs’ insistence on stakeholder participation, independent monitoring, and joint implementation review, underwritten by the EU, empowers domestic non‐governmental organizations with local knowledge to expose problems on the ground, hold public authorities accountable for addressing them, and contribute to developing provisional solutions.
DoWTO+ commitments in services trade agreements reflect a quest for optimal regulatory convergence? Evidence from Asia
Authors: Shingal Anirudh , Roy Martin , Sauvé Pierre 
Published: October 2017

AbstractLiterature examiningWTO+ commitments in services trade agreements (STAs) has not considered the role of services regulation. We bridge this gap using a sample of 15 South/South‐East Asian countries, given the burgeoning trend of Asian economies towards services preferentialism and the largelyWTO+ nature of their preferential services commitments. Our empirical findings suggest that Asian trading dyads with regulatory frameworks that are more similar and more trade restrictive tend to undertake higher levels ofWTO+ commitments in theirSTAs. There is also evidence in our results, including by modes of supply, forWTO+ commitments in AsianSTAs being driven by goods trade complementarities, alluding to supply chain dynamics in the region. Such results support the hypothesis that the heightened “servicification” of production generates a demand to lower services input costs arising from regulatory incidence and heterogeneity.
