SummaryInterMine is a data integration warehouse and analysis software system developed for large and complex biological data sets. Designed for integrative analysis, it can be accessed through a user‐friendly web interface. For bioinformaticians, extensive web services as well as programming interfaces for most common scripting languages support access to all features. The web interface includes a useful identifier look‐up system, and both simple and sophisticated search options. Interactive results tables enable exploration, and data can be filtered, summarized, and browsed. A set of graphical analysis tools provide a rich environment for data exploration including statistical enrichment of sets of genes or other entities. InterMine databases have been developed for the major model organisms, budding yeast, nematode worm, fruit fly, zebrafish, mouse, and rat together with a newly developed human database. Here, we describe how this has facilitated interoperation and development of cross‐organism analysis tools and reports. InterMine as a data exploration and analysis tool is also described. All the InterMine‐based systems described in this article are resources freely available to the scientific community. genesis 53:547–560, 2015. © 2015 Wiley Periodicals, Inc.
Differences in style length confer prezygotic isolation between two dioecious species ofSilenein sympatry
Authors: Nista Phil , Brothers Amanda N. , Delph Lynda F. 
Published: June 2015

AbstractOne fundamental signature of reinforcement is elevated prezygotic reproductive isolation between related species in sympatry relative to allopatry. However, this alone is inadequate evidence for reinforcement, as traits conferring reproductive isolation can occur as a by‐product of other forces. We conducted crosses betweenSilene latifoliaandS. diclinis, two closely related dioecious flowering plant species. Crosses withS. latifoliamothers from sympatry exhibited lower seed set than mothers from five allopatric populations whenS. dicliniswas the father. However, two other allopatric populations also exhibited low seed set. A significant interaction between style length and sire species revealed that seed set declined as style length increased when interspecific, but not intraspecific, fathers where used. Moreover, by varying the distance pollen tubes had to traverse, we found interspecific pollen placement close to the ovary resulted in seed set in both long‐ and short‐styledS. latifoliamothers. Our results reveal that the long styles ofS. latifoliain sympatry withS. dicliniscontribute to the prevention of hybrid formation. We argue that forces other than reinforcing selection are likely to be responsible for the differences in style length seen in sympatry.

AbstractWildfire is the largest disturbance affecting peatland ecosystems and can typically result in the combustion of 2–3 kg C m−2 of near‐surface peat. We hypothesized that organic soil burn severity, as well as the associated carbon emissions, varies significantly as a function of hydrogeological setting due to groundwater impacts on peat bulk density and moisture content. We measured depth of burn (DOB) in three peatlands located along a hydrogeological and topographic gradient in Alberta's Boreal Plains. Peatland margins across all hydrogeological settings burned significantly deeper (0.245 ± 0.018 m) than peatland middles (0.057 ± 0.002 m). Further, hydrogeological setting strongly impacted DOB. A bog with an ephemeral groundwater connection in a coarse‐textured glaciofluvial outwash experienced the greatest DOB at its margins (0.514 ± 0.018 m) due to large water table fluctuations, while a low‐lying oligotrophic groundwater flow‐through bog in a coarse‐textured glaciofluvial outwash experienced limited water table fluctuations and had the lowest margin burn severity (0.072 ± 0.002 m). In an expansive peatland in a lacustrine clay plain, DOB at the margins bordering an isolated domed bog portion (0.186 ± 0.003 m, range: 0.0–0.748 m) was considerably greater than the DOB observed at fen margins with a longer groundwater flow path (<0.05 m). Our research indicates that groundwater connectivity can have a dominant control on soil carbon combustion across and within hydrogeological settings. We suggest that hydrogeological setting be used to identify potential deep burning ‘hotspots’ on the landscape to increase the efficacy of wildfire management and mitigation strategies.

Published: June 2015

AbstractHow rainfall infiltration rate and soil hydrological characteristics develop over time under forests of different ages in temperate regions is poorly understood. In this study, infiltration rate and soil hydrological characteristics were investigated under forests of different ages and under grassland. Soil hydraulic characteristics were measured at different scales under a 250‐year‐old grazed grassland (GL), 6‐year‐old (6yr) and 48‐year‐old (48yr) Scots pine (Pinus sylvestris) plantations, remnant 300‐year‐old individual Scots pine (OT) and a 4000‐year‐old Caledonian Forest (AF). In situ field‐saturated hydraulic conductivity (Kfs) was measured, and visible root:soil area was estimated from soil pits. Macroporosity, pore structure and macropore connectivity were estimated from X‐ray tomography of soil cores, and from water‐release characteristics.At all scales, the median values for Kfs, root fraction, macroporosity and connectivity values tended to AF > OT > 48yr > GL > 6yr, indicating that infiltration rates and water storage increased with forest age. The remnant Caledonian Forest had a huge range of Kfs (12 to >4922 mm h−1), with maximum Kfs values 7 to 15 times larger than those of 48‐year‐old Scots pine plantation, suggesting that undisturbed old forests, with high rainfall and minimal evapotranspiration in winter, may act as important areas for water storage and sinks for storm rainfall to infiltrate and transport to deeper soil layers via preferential flow. The importance of the development of soil hydrological characteristics under different aged forests is discussed. Copyright 2015 British Geological Survey. Ecohydrology © 2015 John Wiley & Sons, Ltd.
Flow‐disturbance considered simulation for algae growth in a river–lake system

Published: June 2015

AbstractA 1‐D–2‐D coupled numerical model embedded with the impact of hydrodynamic conditions on algae growth was developed to simulate the algae concentration for a river–lake system. Based on the laboratory experiment and field investigation, the ‘flow‐disturbance parameter α’ was presented to improve the algae growth formula. By numerical simulation, the algae growth processes in a river–lake system were simulated, and the temporal and spatial distributions of Chl‐a concentration in the area were analysed. Our results show the following: (1) Hydrodynamic conditions play an apparent effect on algae growth. A suitable turbulence is more beneficial for algal proliferation than the static or intense mixing. (2) In the studied area, the flow disturbances in the east–west rivers are generally stronger than that in the north–south rivers, while the Chl‐a concentration is oppositely distributed in the river networks. (3) As a result of the different flow disturbance intensities during periods, the algae cell density in all investigated sections also alters evidently along with the seasons. The average Chl‐a concentration in the dry seasons (November–April) increased by 9.22% than that in the flood seasons (May–October). (4) From the point of the whole river–lake system, the dynamic conditions in the lake inlet areas are more suitable for algae growth than that in the river networks. The Chl‐a concentrations of S2 and S4 are averagely increased by 18.5% than that in the river networks. Copyright © 2015 John Wiley & Sons, Ltd.

AbstractThe reactions of CuSO4·5H2O and Ba(R2mal) [R2mal2– is the dianion of 1,1‐cyclopropanedicarboxylic acid (H2Cpdc), 1,1‐cyclobutanedicarboxylic acid (H2Cbdc), or butylmalonic (H2Bumal) acid] in water give crystals of the 3D coordination polymers [BaCu(Cpdc)2]n (1), [BaCu(Cbdc)2(H2O)]n (2) and [Ba3Cu3(Bumal)6(H2O)11]n·2n(H2O) (3). The heating of 2 in air to 200 °C for 60 min results in the removal of the coordinated water molecules to give anhydrous [BaCu(Cbdc)2]n (4). The structures of 1–3 were determined by single‐crystal XRD, and that of 4 was derived from powder XRD (XPRD) data. It was assumed that the crystal structures of the polymer complexes that we isolated were determined, to a considerable extent, by the nature of the substituent of the dicarboxylic acid. For 2, the dicarboxylic acid contains closed cyclic moieties, which are retained during dehydration to give 4. A comparative study of the thermal decomposition processes and thermal kinetics of 1–3 showed that the dehydration proceeds by a single scheme, and the bonds between the structural moieties in the anhydrous intermediates become stronger. The thermal destruction of the anhydrous compounds 1, 4 and {3} [the dehydrated intermediate of the thermal decomposition of 3, as proved by thermogravimetric analysis (TGA) data] occurs above 170 °C. The phase compositions of their solid products are determined by the thermolysis conditions, and the formation of BaCuO2 from 3 can be realized under milder conditions than those for the formation from 1 and 2.

AbstractA series of pyridine linker containing bis(benz)imidazolium salts serving as precursors to CNC pincer‐type N‐heterocyclic carbene (NHC) ligands were prepared by successive N‐alkylation of the azole core. Binuclear NHC complexes of silver(I) were synthesized by in situ deprotonation of the corresponding (benz)imidazolium salt with silver(I) oxide in acetonitrile at elevated temperature in the dark. Subsequently, pincer‐type palladium(II)–NHC complexes were prepared by transmetalation using silver(I)–NHC complexes in acetonitrile at elevated temperatures. All compounds were fully characterized by elemental analysis, FTIR spectroscopy, and 1H and 13C NMR spectroscopy. X‐ray diffraction studies on single crystals of three compounds confirmed the distorted square‐planar geometry around the palladium(II) center. All complexes are monomeric in nature, and the bis‐NHC ligand chelates in the CNC mode. The effective catalytic potentials of the palladium complexes were demonstrated by their high activities in aqueous‐phase Suzuki–Miyaura and Heck–Mizoroki cross‐coupling reactions of phenylboronic acid and n‐butyl acrylate with a range of functionalized bromobenzene derivatives. The former coupling reaction afforded biphenyls in yields of 71–99 %, whereas the latter reaction evidenced low yields of the n‐butyl cinnamates. Further, all the palladium complexes were studied for their potential in a catalytic hydrosilylation reaction.

AbstractIonic and neutral half‐sandwich guanidinatoruthenium(II) complexes [(η6‐C10H14)RuL(κ2(N,N′){(ArN)2C‐N(H)Ar})][OTf] [Ar = 4‐MeC6H4, L = 2‐methylimidazole (1); Ar = 2‐MeC6H4, L = 1,3,5‐triaza‐7‐phosphaadamantane (PTA; 2)], [(ArNH)3C][(η6‐C10H14)RuCl3] [Ar = 2‐ClC6H4 (3)] and [(η6‐C10H14)RuCl(κ2(N,N′){(ArN)2C‐N(H)Ar})] [Ar = 2‐ClC6H4 (4), 2‐FC6H4 (5), 4‐ClC6H4 (6), and 4‐(NO2)C6H4 (7)] have been isolated and the molecular structures of all but 6 were determined by single‐crystal X‐ray diffraction. VT 31P{1H} NMR spectroscopy of complex 2 revealed the presence of a mixture of four isomers in a ratio of appproximately 1.4:11.0:1.6:0.1. Theoretical calculations were performed on the syn‐syn, syn‐anti, anti‐syn, and anti‐anti conformers of 2, which revealed syn‐anti to be the most stable conformer, both in the gas phase and in solution. Furthermore, the energies relating to the interactions between the lone pairs of the nitrogen atoms of the CN3 unit and the antibonding orbital of the central carbon atom in the syn‐anti conformer of 2 were investigated by NBO analysis. The 1H NMR spectrum of 3 reveals the presence of two species and their ratio is dependent upon the concentration of 3 in CDCl3 and on the amount of D2O in CD3CN. The two species have been ascribed to the presence of a monomer and a water‐bridged dimer. The new complexes 1–7 were screened as pre‐catalysts in the transfer hydrogenation of acetophenone and complex 3 was tested as a pre‐catalyst in the transfer hydrogenation of a variety of ketones to explore the scope of the reaction.

Published: June 2015

AbstractThe reactions of M(NCS)2 (M = Mn, Fe, and Ni) with 4‐acetylpyridine (4‐Acpy) in water lead to the formation of discrete complexes of composition M(NCS)2(4‐Acpy)2(H2O)2, in which the metal cations are coordinated only N‐terminally to the thiocyanato anions. When heated, these precursors dehydrate, and some of them transform into compounds of composition [M(NCS)2(4‐Acpy)2]n, in which the metal cations are linked by pairs of μ‐1,3‐bridging anionic ligands into chains (1D isomer). In contrast, the thermal decomposition of Ni(NCS)2(4‐Acpy)4 or crystallization from solution leads to the formation of an isomeric 2D network of the same composition, which is thermodynamically more stable than the 1D isomer. Temperature‐dependent magnetic measurements of the 1D isomer [Fe(NCS)2(4‐Acpy)2]n at 200 Oe reveal antiferromagnetic ordering at TN = 4.5 K. Field‐dependent measurements show a metamagnetic transition into a saturated paramagnetic phase at a critical field of ca. 700 Oe. In contrast, magnetic measurements of the 2D isomer [Ni(NCS)2(4‐Acpy)2]n at 1000 Oe show a ferromagnetic transition at TC = 8.6 K, whereas only paramagnetic behavior is observed for the Ni 1D isomer.

AbstractA new family of dinuclear iron(II) spin‐crossover (SCO) compounds with the formula [Fe2(μ‐L)2]X4, with three different counteranions [X = BF4– (1), ClO4– (2) and F3CSO3– (3)], was prepared and characterized by single‐crystal X‐ray diffraction, variable‐temperature magnetic susceptibility and Mössbauer measurements. These are the first dinuclear iron(II) SCO complexes with a 1,3,4‐thiadiazole bridging ligand L {with L = 2,5‐bis[(2‐pyridylmethyl)amino]methyl‐1,3,4‐thiadiazole}. The magnetic measurements reveal a gradual and incomplete SCO of the three compounds around room temperature, starting from a diamagnetic [LS–LS] state. The diamagnetic ground state is in agreement with the single‐crystal X‐ray diffraction and Mössbauer data.
A ground motion selection procedure for enforcing hazard consistency and estimating seismic demand hazard curves
Authors: Kwong N. Simon , Chopra Anil K. , McGuire Robin K. 
Published: June 2015

SummaryThis paper develops a procedure to select unscaled ground motions for estimating seismic demand hazard curves (SDHCs) in performance‐based earthquake engineering. Currently, SDHCs are estimated from a probabilistic seismic demand analysis, where several ensembles of ground motions are selected and scaled to a user‐specified scalar conditioning intensity measure (IM). In contrast, the procedure developed herein provides a way to select a single ensemble of unscaled ground motions for estimating the SDHC. In the context of unscaled motions, the proposed procedure requires three inputs: (i) database of unscaled ground motions, (ii) IM, the vector of IMs for selecting ground motions, and (iii) sample size, n; in the context of scaled motions, two additional inputs are needed: (i) a maximum acceptable scale factor, SFmax, and (ii) a target fraction of scaled ground motions, γ. Using a recently developed approach for evaluating ground motion selection and modification procedures, the proposed procedure is evaluated for a variety of inputs and is demonstrated to provide accurate estimates of the SDHC when the vector of IMs chosen to select ground motions is sufficient for the response quantity of interest.

Published: June 2015

AbstractObjectiveFirst studies revealed overgeneral autobiographical memories in anorexia nervosa (AN) patients. The aim of the present study was to investigate frequency, generalization and valence of autobiographical memories in AN patients in response to eating disorder‐related cue words.MethodAutobiographical memory was examined in 21 AN patients and 21 healthy controls (HC) using a modified version of the Autobiographical Memory Test, incorporating body‐related, food‐related, perfectionism‐related, depression‐related and neutral cues.ResultsAnorexia nervosa patients recalled fewer and more general autobiographical memories compared with HC. For eating disorder‐related cues as against neutral ones, AN patients compared with HC showed fewer memories for food‐related and body‐related cues, an elevated overgeneralization for food‐related cues, while the valence of the retrieved memories was more negative in response to body‐related cues.DiscussionThis study detects disorder‐related autobiographical memory alterations in AN, which are intensified in response to symptom‐related cues. The findings are discussed with regard to their maladaptive function in emotion regulation. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.
Immediate Effects of Body Checking Behaviour on Negative and Positive Emotions in Women with Eating Disorders: An Ecological Momentary Assessment Approach
Authors: Kraus Nicole , Lindenberg Julia , Zeeck Almut , Kosfelder Joachim , Vocks Silja 
Published: June 2015

AbstractObjectivesCognitive‐behavioural models of eating disorders state that body checking arises in response to negative emotions in order to reduce the aversive emotional state and is therefore negatively reinforced. This study empirically tests this assumption.MethodsFor a seven‐day period, women with eating disorders (n = 26) and healthy controls (n = 29) were provided with a handheld computer for assessing occurring body checking strategies as well as negative and positive emotions. Serving as control condition, randomized computer‐emitted acoustic signals prompted reports on body checking and emotions.ResultsThere was no difference in the intensity of negative emotions before body checking and in control situations across groups. However, from pre‐ to post‐body checking, an increase in negative emotions was found. This effect was more pronounced in women with eating disorders compared with healthy controls.DiscussionResults are contradictory to the assumptions of the cognitive‐behavioural model, as body checking does not seem to reduce negative emotions.

Weakening of gneiss surfaces colonized by endolithic lichens in the temperate climate area of northwest Italy

Published: June 2015

AbstractA role of lithobionts in geomorphological processes is increasingly argued, but the spatio‐temporal scale of their impact is largely unexplored in many ecosystems. This study first characterizes in the temperate zone (northwest Italy) the relationships between lithobiontic communities including endolithic lichens and the hardness of their siliceous rock substrate (Villarfocchiardo Gneiss). The communities are characterized, on humid and xeric quarry surfaces exposed for decades and natural outcrops exposed for centuries, in terms of lichen and microbial constituents, using a combined morphological and molecular approach, and with regard to their development on and within the gneiss.A lichen species belonging to Acarosporaceae (Polysporina‐Sarcogyne‐Acarospora group, needing taxonomic revision) chasmoendolithically colonizes both the humid and xeric quarry surfaces, on which epilithic cyanobacterial biofilms and epilithic pioneer lichens respectively occur. Light and electron microscopic observations show the development of the endolithic thalli within rock microcracks and the hyphal penetration along crystal boundaries down to depths of 1 to 3 mm, more pronounced within the humid surfaces. Such colonization patterns are likely related to biogeophysical deterioration, while no chemical alteration characterizes minerals contacted by the endolithic lichen. By contrast, on natural outcrops, where the endolithic colonization is negligible, a reddish rind below epilithic lichens indicates chemical weathering processes.Schmidt Hammer measurements highlight that the endolithic lichens deeply affect the hardness of the gneiss (down to −60% with respect to fresh controls and surfaces only colonized by cyanobacteria), exerting a significantly higher weakening effect with respect to the associated epilithic lithobionts. The phenomenon is more remarkable on humid than on xeric quarry surfaces and natural outcrops, where epilithic lichens are likely involved in long‐term hardening processes supporting surface stabilization.Endolithic lichens are thus active biogeomorphological agents at the upper millimetric layer of siliceous rocks in temperate areas, exerting their weakening action during the early decade‐scaled stages of surface exposure.
