Mating Frequency and Fecundity in Agrilus anxius (Coleoptera: Buprestidae)
Authors: Rutledge Claire E , Keena Melody A 
Published: November 2012

Abstract
Bronze birch borers (Agrilus anxius Gory) (Coleoptera: Buprestidae), a key pest of birches in North America, have the potential to be a major threat to Eurasian birch forests. Therefore, the consequences of single versus multiple mating on the longevity, fecundity and fertility of female A. anxius were examined. There were three treatments: females observed mating one time and 1 ) then housed alone, 2) kept with their mate, and 3) females paired and housed with a randomly chosen male. Another group of females were observed mating once, and then dissected, 47 of 48 of them had received spermatophores. Weight and longevity of females did not differ among mating treatments. Fecundity, but not fertility, was positively correlated with longevity in all treatments. A high percentage of females in all three mating treatments laid eggs, and there was not a significant difference among treatments. The fecundity of females that laid eggs also did not differ among treatments. These results suggest that a single successful mating may be sufficient to ensure maximal fecundity for females, and that potential for failure of any mating is low. However, there is no apparent cost to multiple mating. Thus, multiple mating may increase fecundity for female bronze birch borers. Our results suggest that laboratory rearing protocols need not ensure females mate multiple times. At the population level, our results suggest that a mate-finding Allee effect at low population densities is unlikely. We also compare the results to an earlier study with the emerald ash borer, Agrilus planipennis Fairmaire.

Abstract
Structural analyses of eggs from Reduviidae may provide important data to establish relationships among the representatives of this family. This study described the eggshell morphology of Harpactor angulosus (Lepeletier and Serville 1825) (Reduviidae: Harpactorinae). Eggs of H. angulosus were analyzed using a stereoscopic microscope and a scanning electron microscope. Eggs of H. angulosus are oval-shaped and slightly flattened laterally, with an eggshell surface with several pores and a rounded posterior pole. The anterior pole has a poorly pronounced neck region, without formation of the collar and a small chorionic rim and with an incomplete anterior appendage without connection between the veil and opercular projections. Aeropyles have a tube-like aspect, arising in the middle region of the veil and extending until the sealing bar. Eggs of H. angulosus were similar to those of other Harpactorinae, but with differences in length, width, anterior appendage characteristics, and eggshell invaginations.
A 3-D genetic approach to high-resolution geological modelling of the volcanic infill of a paleovalley system. Application to the Volvic catchment (Chaîne des Puys, France)
Authors: Rouquet Simon , Boivin Pierre , Lachassagne Patrick , Ledoux Emmanuel 
Published: November 2012

Abstract
The Volvic natural mineral water is catched in a complex volcanic aquifer located in the northern part of the “Chaîne des Puys” volcanic system (Auvergne, France). In the watershed, water transits through scoria cones and basaltic to trachybasaltic lava flows. These aa lava flows, emitted by strombolian cones between 75,000 and 10,000 years ago, are emplaced in deep paleovalleys incised within the variscan crystalline bedrock. The volcanic infill is highly heterogeneous. In order to build a hydrogeological model of the watershed, a simple but robust methodology was developed to reconstruct the bedrock morphology and the volcanic infill in this paleovalley context. This methodology, based on the combination of genetic and geometric approaches, appears to be rather efficient to define both the substratum and the lava flows geometry. A 3D geological model is then proposed. It synthesizes the data from 99 boreholes logs, 2D geoelectric profiles, morphologic clues, datings and petrographic data. A genetic approach, integrating aa lava flow morphology and emplacement behaviour, was used to reconstruct the chronology of the volcanic events and lava flow emplacement from the upper part of the Dômes plateau to the Limagne plain. The precision of the volcanic reconstruction is discussed: the main limitation of the methodology are related to the homogeneity of the petrographic and geochemical composition of the lava flows succession (except for the trachyandesitic Nugere lava), the spatially variable borehole density, the lack of a real petrographical and geological description on most of the available geological logs. Nevertheless, the developed methodology combining spatial and genetic approaches appears to be well adapted to constrain complex lava flow infill geometries in paleovalley context.
Mise en évidence par le paléomagnétisme de rotations régionales dans la virgation des Corbières (France)
Authors: Rouvier Henri , Henry Bernard , Le Goff Maxime 
Published: November 2012

AbstractUne réaimantation “syntectonique” éocène a été mise en évidence dans toute la virgation des Corbières, des Fenouillèdes à l’arc de Saint-Chinian. Son analyse montre que le synclinorium de Saint-Paul de Fenouillet a conservé son orientation E-W originelle, alors que son extrémité orientale a subi une torsion anti-horaire importante à l’amorce de la virgation. La branche méridienne de la virgation est composée de blocs plurikilométriques qui présentent une rotation senestre homogène sur toute leur surface, mais différente d’un bloc à l’autre. Le paléomagnétisme a permis de mettre l’accent sur le caractère majeur de l’accident de Vingrau, orienté NE-SW comme le réseau de failles des Cévennes, qui limite des blocs ayant subi, de part et d’autre, des rotations de valeurs différentes. En outre, il a été démontré que localement le socle avait subi la même rotation au même titre que la nappe des Corbières qui le surmonte. La comparaison des données paléomagnétiques avec la réaimantation, déterminée dans les Cévennes et ayant permis de dater de l’Eocène les minéralisations sulfurées liées aux strates (MVT), montre que la même réaimantation est présente dans l’avant-pays pyrénéen.
Marine karstic infillings: evidence of extreme base level changes and geodynamic consequences (Paleocene of Languedoc, south of France)

Published: November 2012

Abstract
Late Jurassic platform carbonates of Languedoc (southern France) are deeply incised by Late Miocene canyons, allowing the observation of karst systems filled with sediments containing evidences of marine origin. Field and structural relationships as well as new biostratigraphic data (planktonic foraminifera and calcareous nannofossils) provide a Latest Cretaceous-Earliest Paleocene age for the major karstification and a Paleocene (Danian-Selandian) age for the sedimentary filling. The ≥ 350 m vertical extent of this karst system and its subsequent marine filling gives a minimum amplitude for the base-level variation responsible for the karstification and then the marine flooding events. The observations suggest that at least, two marine successive events occurred in the Late Danian then in Selandian time. The large amplitude of base level is not in agreement with eustatic sea-level change, and the rate of base-level change is too fast for tectonic uplift and subsidence within the tabular, poorly deformed studied area. We propose a model of a silled endoreic basin, which was dessiccated and karstified over hundreds of meters, when it was disconnected from the World Ocean, and later suddently transgressed by the Paleocene sea and the karst flooded, when the bounding sill was submerged. Such a model is similar, although with significant differences, with the later Messinian-Zanclean event that affected the Mediterranean realm.
Exhumation of subcontinental mantle rocks: evidence from ultramafic-bearing clastic deposits nearby the Lherz peridotite body, French Pyrenees

Published: November 2012

Abstract
In the eastern Pyrenees, the lherzolites always outcrop as restricted bodies scattered across Mesozoic sedimentary units along the North Pyrenean fault. In this article, we focus on the sedimentary processes associated with the tectonic exhumation of the mantle rocks during the Lower Cretaceous and we provide a new detailed analysis of the ultramafic-bearing sedimentary sequences associated with the Lherz body. The Lherz body, 1.5 km long only, belongs to a series of ultramafic bodies of restricted size (a few m to some hundred of m), occurring within sedimentary formations composed mostly of carbonate breccias originating from the reworking of Mesozoic platform limestones and dolomites. The carbonate clasts include marbles displaying different evolutions in relation with the Cretaceous thermal metamorphic event. The clastic formations also include numerous layers of polymictic breccias reworking ultramafic clasts. These layers are found far from any peridotitic body, implying that ultramafic clasts have been transported far away from their sources by sedimentary processes after their disaggregation on the seafloor. In addition, clasts of ultramafic-rich breccias and sandstones are also observed which indicates rapid sedimentation and diagenesis within a tectonically active environment. We discuss the significance of these deposits and their bearing on our understanding of the tectono-sedimentary processes associated with mantle exhumation in a context of development of narrow intracontinental basins suffering extreme crustal thinning.

Published: November 2012

Objective: To evaluate patient and physician characteristics associated with the type of psychotropic medications (anti-anxiety, antidepressant, or both) purchased. Methods: The Clalit Health Care Services is the largest managed care health fund in Israel, a country that employs a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 as of January, 2006. Results: Overall, 2,217 purchased either antidepressant or antianxiety medications at least once during the year 2006 and had no prior purchases during the last quarter of 2005. The majority (1,518; 68.4%) purchased only anti-anxiety medications and as many as 264 (12%) purchased both anti-anxiety and antidepressant medications. The remaining 435 (19.6%) patients purchased only antidepressant medications. Physician level characteristics explained only a small portion of the variance and, thus, were not included in further analysis. Several patient level characteristics, including age, somatic, and psychiatric diagnosis were associated with the purchase of different types of medications. Conclusions: Contrary to clinical guidelines, the purchase of anti-anxiety medications is more prevalent than the purchase of antidepressant medications. In a managed care setting, patient characteristics have a greater role in determining purchasing patterns than provider characteristics; potentially, because of the managed care characteristics that actively guide the care provided to patients.
The Ghost of the Unnameable
Authors: Sellars Roy 
Published: November 2012

According to Jacques Derrida, there is a différance – his infamous mis-spelling of the French différence – that ‘has no name in our language’ (‘Différance’, in Margins of Philosophy); its name is not différance, and it is not just nameless but ‘unnameable’. ‘The a of différance’, he also tells us, ‘remains silent, secret and discreet as a tomb’. My essay, which is haunted throughout by Derrida, seeks to address the following question: if the a of différance is like a tomb, then who or what died?To Kzomil
Germination failure is not a critical stage of reproductive isolation between three congeneric orchid species
Authors: De hert Koen , Honnay Olivier , Jacquemyn Hans 
Published: November 2012

• Premise of the study: In food‐deceptive orchid species, postmating reproductive barriers (fruit set and embryo mortality) have been shown to be more important for reproductive isolation than premating barriers (pollinator isolation). However, currently there is very little knowledge about whether germination failure acts as a reproductive barrier in hybridizing orchid species.• Methods: In this study, we investigated germination and protocorm development of pure and hybrid seeds of three species of the orchid genus Dactylorhiza. To test the hypothesis that germination failure contributed to total reproductive isolation, reproductive barriers based on germination were combined with already available data on early acting barriers (fruit set and embryo mortality) to calculate the relative and absolute contributions of these barriers to reproductive isolation.• Key Results: Protocorms were formed in all crosses, indicating that both hybrid and pure seeds were able to germinate and grow into protocorms. Also, the number of protocorms per seed packet was not significantly different between hybrid and pure seeds. High fruit set, high seed viability, and substantial seed germination resulted in very low reproductive isolation (average RI = 0.05). In two of six interspecific crosses, hybrids performed even better than the intraspecific crosses.• Conclusions: Very weak postmating reproductive barriers were observed between our study species and may explain the frequent occurrence of first‐generation hybrids in mixed Dactylorhiza populations. Germination failure, which is regarded as one of the most important bottlenecks in the orchid life cycle, was not important for reproductive isolation.

Published: November 2012

Purpose We investigated the effects of alumina addition on microstructure and compressive strength of a porous silicate substituted hydroxyapatite (Si-HA). Methods Hydroxyapatite (HA) was synthesized under precipitation conditions and 10 %Wt. of sol–gel derived CaO. P2O5.SiO2 based bioglass (BG) powder was added to HA. Polyurethane foam was used to form a high porous structure with integral porosity of 70%. Phase analysis was performed using XRD and FTIR and the microstructure was studied using SEM. Results The results confirmed that the Si-HA was the only formed phase before Al2O3 addition while after addition the presence of silicon-incorporated HA and alumina without any other phases was proved using these analyses. Conclusions The porous structures of Si-HA and Al2O3 were synthesized using the replication technique. The compressive strength of porous bioceramics increased with increasing Al2O3 content up to 30 wt % (ANOVA, p<.05).
Glenn Gould : les stratégies du compositeur et la musique de son temps d’après sa correspondance
Authors: Guertin Ghyslaine 
Published: November 2012

Si le Gould virtuose du piano est bien connu, le Gould compositeur l’est beaucoup moins. Pourtant sa démarche se manifeste très tôt dans ses projets d’écriture ambitieux – musiques de chambre, opéras, symphonies – et dans son attitude négative à l’égard de sa vie de concertiste l’empêchant de se réaliser. Sa demi-retraite de la scène en 1962 – soit deux ans avant de mettre fin définitivement à sa carrière de concertiste – constitue une première étape dans l’accomplissement du rêve de sa vie : devenir compositeur et pouvoir se consacrer entièrement à l’évolution de l’écriture déjà amorcée dans le passé. Cet article propose une visite dans ce vaste atelier de création regroupant les activités compositionnelles de Gould et ses idées sur la musique de son temps, telles que représentées surtout dans sa correspondance.
Permanent deficits in handgrip strength and running speed performance in low birth weight children

Published: November 2012

AbstractObjective:The main goal of this study was to verify the influence of low birth weight (LBW) on the physical fitness of children aged 7–10 years. The comparisons were subsequently adjusted for chronological age, gender, physical activity (PA), and body composition.Methods:A total of 356 children of both genders born in Vitoria de Santo Antão (Northeast of Brazil) were divided into two groups according to their birth weight (LBW < 2.500 g, n = 100, and normal birth weight, NBW ≥ 3.000 g and ≤ 3.999 g, n = 256). Body composition measurements included body weight, height, body mass index, triceps, and subscapular skinfolds, and body fat percentage (%BF). PA was assessed by a questionnaire. Physical fitness was assessed by handgrip strength, muscle endurance, explosive power, flexibility, agility, maximal oxygen consumption (VO2max), and running speed.Results:LBW children were shorter, lighter, had lower fat‐free mass, muscle strength, and running speed but a higher VO2max than the NBW group. The differences in body weight (P = 0.507), height (P = 0.177), fat‐free mass (P = 0.374), and VO2max (P = 0.312) disappeared when adjusted for covariates. The differences in right and left handgrip strength (P < 0.01) and running speed (P < 0.01) remained significant even when controlled for age, gender, height, fat‐free mass, and PA.Conclusion:This combined analysis suggests that LBW alone can be not considered as a biological determinant of growth, body composition, or physical fitness in children, but is a predictor of muscle strength and running speed.

Published: November 2012

AbstractObjectives: This study aimed to assess the accuracy and concordance of anthropometrically derived prediction equations for the estimation of regional fat mass (FM) distribution.Methods: Sixty‐two white males and 50 females with a large range of age (20−55 years) and BMI (16.6−33.4 kg/m2) were included. Whole body dual energy X‐ray absorptiometry (DXA) scans were acquired and anthropometric prediction equations for regional FM were developed and cross‐validated. On the basis of the total sample two anthropometrically derived indices of FM distribution
$\Big({{{\rm FM}_{{\rm trunk}} } \over {{\rm FM}_{{\rm limbs}} }}$
ratio and ${{{\rm \%FM}_{{\rm trunk}} } \over {{\rm \%FM}_{{\rm legs}} }} \ {\rm ratio}\Big)$
were compared with their DXA analogues.Results: In both sexes multiple linear regression models predicted the regional DXA fat masses with good accuracy (P < 0.001). In men mean bias (limits of agreement) were: −6.8 g (−535,364) for FMarms, 65 g (−1921,2052) for FMtrunk, −21 g (−1374,1332) for FMlegs, −0.2% (−5.0,4.7) for %FMtrunk and −0.5% (−6.8,5.8) for %FMlegs. In women mean difference (limits of agreement) were: −86 g (−463,450) for FMarms, 30 g (−1784,1844) for FMtrunk, −278 g (−1782,1227) for FMlegs, 0.4% (−5.5,6.3) for %FMtrunk, and 0.3% (−8.3,8.9) for %FMlegs. No systematic (constant and proportional) differences between methods for the determination of FM distribution ratios were found, suggesting method interchangeability. The concordance for subject classification based on t‐scores according to the National Health and Nutrition Examination Survey (NHANES) was significant (P < 0.001), with substantial agreement for
${{{\rm FM}_{{\rm trunk}} } \over {{\rm FM}_{{\rm limbs}} }}$
ratio (κw = 0.80) and ${{{\rm \%FM}_{{\rm trunk}} } \over {{\rm \%FM}_{{\rm legs}} }}$
ratio (κw = 0.75).Conclusion: Anthropometric variables offer promise to the development of simple, noninvasive, and inexpensive screening to identify individuals with abnormal FM distribution. The anthropometrically derived indices of FM distribution demonstrate sufficient accuracy for clinical use. Am. J. Hum. Biol., 2013. © 2012 Wiley Periodicals, Inc.
Relationship of 2D:4D finger ratio with androgen receptor CAG and GGN repeat polymorphism
Authors: Zhang Chuan , Dang Jie , Pei Liguo , Guo Mengjing , Zhu Hao , Qu Lei , Jia Fei , Lu Hong , Huo Zhenghao 
Published: November 2012

AbstractObjectives:The relative length of the second‐to‐fourth digits (2D:4D) has been linked with prenatal androgen in humans. A recent study shows that the 2D:4D ratio in mice is controlled by the balance of androgen to estrogen signaling during a narrow window of digit development. Androgen receptor (AR) activity is higher in digit 4 than in digit 2, and inactivation of AR decreases growth of digit 4, which causes a higher 2D:4D ratio. At the molecular level, the effect of androgens is mediated through the activation of AR. The CAG/GGN repeat polymorphisms of the AR gene are associated with AR activity. Here, we investigate the effect of CAG/GGN repeat polymorphisms in AR on 2D:4D in Chinese.Methods:Digit lengths of the second and fourth fingers were measured from photocopies of the ventral surface of the hand and by actual finger measurements. We genotyped AR polymorphisms by ABI 3730 DNA analyzer.Results:We found that left hand 2D:4D ratio was longer than that of the right hand both in males and in females. We failed to find any relationship between CAG / GGN alleles and the left hand, right hand, right minus left‐hand or mean hand 2D:4D ratios (all, r < 0.20, P > 0.05).Conclusions:In this study, we first found that the left hand 2D:4D ratio was longer than that of the right hand in both males and females. However, we found that both CAG and GGN alleles were not associated with the left hand, right hand, right minus left‐hand or mean hand 2D:4D ratios. Am. J. Hum.
