Abstract

International audience; Despite the growing interest for boron nitride nanotubes (BNNT) due to their unique properties, data on the evaluation of the environmental risk potential of this emerging engineered nanomaterial are currently lacking. Therefore, the ecotoxicity of a commercial form of BNNT (containing tubes, hexagonal-boron nitride, and boron) was assessed in vivo toward larvae of the amphibian Xenopus laevis. Following the exposure, multiple endpoints were measured in the tadpoles as well as in bacterial communities associated to the host gut. Exposure to BNNT led to boron accumulation in host tissues and was not associated to genotoxic effects. However, the growth of the tadpoles increased due to BNNT exposure. This parameter was associated to remodeling of gut microbiome, benefiting to taxa from the phylum Bacteroidetes. Changes in relative abundance of this phylum were positively correlated to larval growth. The obtained results support the finding that BNNT are biocompatible as indicated by the absence of toxic effect from the tested nanomaterials. In addition, byproducts, especially free boron present in the tested product, were overall beneficial for the metabolism of the tadpoles.

Abstract

International audience; Geosynphytosociology deals with the study of combinations of vegetation series – or geosigmeta – within landscape. Its main advantage is to assess conservation status based on vegetation dynamics. However, this field-based approach has not been widely applied, because local surveys are not representative of spatio-temporal landscape complexity, which leads to uncertainties and errors for geosigmeta structural and functional mapping. In this context, satellite time series appear as relevant data for monitoring vegetation dynamics. This article aims to assess the contribution of an annual satellite time series for geosigmeta structural and functional mapping. The study area, which focuses on the French Atlantic coast (4630 km²), includes salt, brackish, sub-brackish and fresh marshes. A structural vegetation map was derived from the classification of an annual time series of 38 MODIS images validated with field surveys. The functional vegetation map was derived from the annual Integral of Normalized Difference Vegetation Index (NDVI-I), as an indicator of above-ground net primary production. Results show that geosigmeta were successfully mapped at a scale of 1:250,000 with an overall accuracy of 82.9%. The geosigmeta functional map highlights a strong gradient from the lowest NDVI-I values in salt marshes to the highest values in fresh marshes.

Abstract

Andreaea rothii has been recorded for the first time in Croatia. It is a boreo-temperate suboceanic species (Hill et al., 2007) relatively rare in SE Europe, since it is known only from Romania (Ellis et al., 2014d), Slovenia and Serbia (Sabovljevic´ et al., 2008 ; Hodgetts, 2015). The species was found in the Papuk Mountains, situated in the mainly lowland area of NE Croatia. In this region Papuk is the largest and highest mountain range, with peaks between 800 and 900 m a.s.l. They are characterized by high geological diversity dominated by metamorphic rocks, such as different types of schists, as well as granites. The climate is temperate, moderately warm without an explicit dry period. About 60% of the almost totally forested area is covered by different communities of beech forests. The well-developed black patches of A. rothii cover an area ca 2 m× 0.5 m on a steep north-facing cliff on the edge of an acidothermophilic sessile oak (Quercus petraea agg.) forest. The specimens of A. rothii grew on the bare rock with the following bryophyte species: Cynodontium polycarpon (Hedw.) Schimp., Dicranella heteromalla (Hedw.) Schimp., Dicranum scoparium Hedw., Polytrichum piliferum Schreb. ex Hedw. and Rhabdoweisia (cf.) fugax (Hedw.) Bruch & Schimp. The population is very small with an extremely high risk of extinction, therefore we propose CR as Red List status for the taxon in Croatia. According to the last checklist of the moss flora of Croatia (Sabovljevic´, 2006), only Andreaea rupestris Hedw., collected from just one locality in 1927 (Horvat, 1932 and ZA), was reported for the genus. The locality is very interesting from the point of view of the vegetation of Croatia, because it is within 100 m of the second stand of Fagus sylvatica L.-Sphagnum quinquefarium (Braithw.) Warnst. forest (Alegro et al., 2015). The second occurrence of Dicranum spurium Hedw. (Ellis et al., 2014d) and Rhabdoweisia fugax (Papp et al., 2013) in Croatia are also found here. Another interesting moss is S. capillifolium (Ehrh.) Hedw., that forms small red patches within the thick carpets of S. quinquefarium under the open oulder scree forest in the neighbourhood.

Abstract

The decline of bees is a major concern due to their vital role inpollinating many crops and wild plants. Some regions in SouthAmerica, and especially the Pampas, are amongst those parts ofthe world where stressors of bee populations have been littlestudied. The Pampas has been intensively transformed for agriculture,being presently one of the most productive areas of agriculturalcommodities in the world. Here, we aim to provide firstinsights on the taxonomic and functional composition of beeassemblages in the Rolling Pampa, the most intensively managedpart of the Pampas. Soybean (herbicide-tolerant genetically modifiedvarieties) is the predominant crop in this region. Bees weresampled with coloured pan traps. Sampling points were locatedon field margins in either the cropped or the semi-natural grasslandarea of a farmland site devoted to annual cropping. A total of2384 individuals were caught, representing 33 taxa [mainly (morpho)species]. The subgenus Lasioglossum (Dialictus) largely dominatedcaptures (78% of the total abundance) and was relativelyabundant in the entire study area, suggesting that some speciesare likely to reach their ecological requirements in cropped areas.No-till fields and field margins may provide large areas for thesebelow-ground nesting species, while their polylectic food preferencesallow them to collect pollen on a wide range of plantspecies, among them possibly soybean. On the contrary, the richnessand the abundance of other taxa were higher in the seminaturalarea than in the cropped area. Among them, abovegroundnesting or oil-collecting species, which have more specialisednesting and floral requirements, were highly associated withthe semi-natural area. Our findings highlight the large dominanceof L. (Dialictus) species in this highly intensively managed landscape,and the urgent need of preserving semi-natural habitats tomaintain species-rich and functionally diverse bee communities inthe Pampas.

Abstract

International audience; A new species of Hypaeus Simon 1900 is described from French Guiana based on both sexes, Hypaeus olympeae sp. nov. We employed morphological evidence, field observation, as well as the mitochondrial COI rapidly evolving loci to confirm that both males and females belong to the same species. Finally, nine species are newly recorded for the salticid fauna of French Guiana, Cyllodania fasciata (Caporicaco, 1954) syn. nov. is considered junior synonym of Gypogyna forceps Simon, 1900 and 12 COI sequences corresponding to four previously unsequenced Hypaeus species are added to GenBank.

Abstract

International audience; Since the 1970s, rainfall has declined along the North African coast, while the demographic pressure has increased. Supplementing the rainfall data and water level of the Béni Bahdel dam, water isotopic signature and tree ring analyses were used to better understand the effects of climate change (lower rainfall, higher summer temperature) and the water circulation in the Tafna River basin in north-west Algeria. Changes are recommended in water storage and afforestation policies and irrigation techniques.

Abstract

The evaluation of the impact of gradual environmental changes, such as the salinization of freshwaters, requires measures that are sensitive enough to detect the subtle changes that may be occurring within a population. Fluctuating asymmetry (FA) has been used widely to investigate questions regarding fitness and behavior, and to study the effects of environmental pollution. Asymmetries in the femur lengths of Calopteryx splendens (Odonata) larvae, and in the femur lengths, the tibia lengths and the pygopod widths of Hydropsyche exocellata and H. contubernalis (Trichoptera) larvae were studied at three sites along a salinity gradient of the Meurthe River (France). The difference in salinity between the sites (ranging from 0.21 to 2.60 g.L−1) was the only parameter varying to a degree significant enough to potentially affect damselfly or caddisfly development and their population densities. While no directional asymmetry or anti-symmetry was found, fluctuating asymmetry was observed for each species, each anatomic piece and for each site. Although C. splendens densities decreased along the salinity gradient, C. splendens FA did not differ significantly between traits and between sites. The same analysis on H. contubernalis showed that FA differed significantly between traits but not between sites in spite of a decrease of densities. H. exocellata FA differed significantly between traits and between sites but FA reached the lowest value for the intermediate salinity level. Finally, no relationships were observed between FA and the salinity gradient or between FA and the population density pattern observed for each species. Thus, according to our results, the FA of natural population of these insects seems to be a poor bioindicator of the salinity stress.

Abstract

About 25 m3 of a poplar bark-poultry dung mixture were composted in a covered place with natural ventilation, air entering the lower part and going out through four shafts in the upper part. The gaseous emissions were measured and analyzed. The first heap (initial C/N of 28) was monitored for one month, then turned and more dung added. The second heap (initial C/N of 8) was monitored for seven months with two intermediate turnings. For the whole experiment, N losses were estimated at 61-74% of initial N, of which 62% was lost as NH3 (38-46% of initial N) and 1% as N2O (0.6-0.7% of initial N). N-NOx losses were 1000 times lower than N-N3 H3 losses. N2O and NOx were found only at the end of the periods before the piles were turned. As for carbon, C-CO2 emissions were estimated at 45-55% of initial C content, the ratio of CH4 to CO2 in the effluent air was 1 to 100 on average, with significant variations. The global warming potential of CH and N O was estimated at respectively 25% and 50% of total CO2 emissi...

Abstract

The association chitosan/linoleic acid/lactobionic acid in aqueous solution spontaneously led to the formation of stable microparticles with a liquid hydrophobic core consisting of linoleic acid surrounded by a shell of chitosan/lactobionic acid. The originality of the microparticles arises from the fact that they are formed by the association of three ingredients of cosmetic interest, including a skin penetration enhancer (linoleic acid). Dynamic light scattering (DLS) measurements showed microparticles with a mean diameter of 1–2 μm. The presence of a hydrophobic liquid core was observed by transmission electron microscopy (TEM). The ability of these microparticles to encapsulate phenylethyl resorcinol, a hydrophobic skin lightener, was evaluated and its encapsulation was confirmed thanks to T2 measurements and nuclear Overhauser effects (nOe) signs.

Abstract

The low-density lipoprotein receptor-related protein-1 (LRP-1) is a member of Low Density Lipoprotein Receptor (LDLR) family, which is ubiquitously expressed and which is described as a multifunctional endocytic receptor which mediates the clearance of various extracellular matrix molecules including serine proteinases, proteinase-inhibitor complexes, and matricellular proteins. Several studies showed that high LRP-1 expression promotes breast cancer cell invasiveness, and LRP-1 invalidation leads to cell motility abrogation in both tumor and non-tumor cells. Furthermore, our group has reported that LRP-1 silencing prevents the invasion of a follicular thyroid carcinoma despite increased pericellular proteolytic activities from MMP2 and uPA using a 2D-cell culture model. As the use of 3D culture systems is becoming more and more popular due to their promise as enhanced models of tissue physiology, the aim of the present work is to characterize for the first time how the 3D collagen type I matrix may impact the ability of LRP-1 to regulate the migratory properties of thyroid carcinoma using as a model FTC-133 cells. Our results show that inhibition of LRP-1 activity or expression leads to morphological changes affecting cell-matrix interactions, reorganizations of the actin-cytoskeleton especially by inhibiting FAK activation and increasing RhoA activity and MLC-2 phosphorylation, thus preventing cell migration. Taken together, our results suggest that LRP-1 silencing leads to a decrease of cell migratory capacity in a 3D configuration.

Abstract

International audience; In this work, aqueous dispersions of PolyEtherKetoneKetone (PEKK) oligomers were obtained by an emulsion/dispersion solvent evaporation technique. The PEKK oligomers were synthesized by a Friedel–Crafts acylation with a number average degree of polymerization of 4. The synthesized PEKK oligomers had very good thermal stability and spontaneously formed a stable dispersion of swollen micrometric fibers in chloroform. After sonication of the chloroform dispersion in water in the presence of sodium dodecyl sulfate (SDS) and evaporation, we obtained aggregated particles with a mean diameter between 120 and 160 nm, decreasing linearly with the PEKK concentration. The most stable dispersions were obtained with 0.5% wt of surfactant and, at a fixed concentration of SDS, the stability decreased when the PEKK concentration was increased. The different dispersions of PEKK in water were very stable and, after water evaporation, formed homogeneous films for high-performance coating.

Abstract

International audience; The aquatic herbivorous and capital-breeding moth Acentria ephemerella Denis andSchifferm€uller, 1775 feeds on submerged pondweeds, Potamogeton spp., and is highlypreyed upon by fish in the littoral zone. We studied the spatiotemporal within-lakevariability of length, sexual size dimorphism (SSD) and sex ratio of A. ephemerellapupae and of larval population densities. Population densities at three sampling sitesstrongly increased from July to August and were significantly higher at the Reichenausite in July. Acentria ephemerella sex ratio was male-biased at the G€uttingen andHagnau sites, but showed unbiased or slightly biased sex ratios at Reichenau. TheSSD was strongly female-biased. Female size and SSD declined during summer,possibly due to reduced food quantity/quality. The SSD was highest at Reichenau,with little to no differences between Hagnau and G€uttingen. At Reichenau, the highpopulation size in July coincided with an unbiased sex ratio, and large SSD/femalesize due to multiple, possibly interacting factors, including fish predation.

Taylor & francis inc Philadelphia; The influence of vetiver grass (Vetiveria zizanioides) on the fate of endosulfan was studied using a vertisol and a lixisol soils from cotton-growing areas of Burkina Faso. Endosulfan adsorption isotherms were prepared for planted and unplanted soils. Pot experiments were then conducted for six months. For both soils, endosulfan adsorption was higher on planted soils (K-f= 6.53-9.73mg(1-n)L(n)kg(-1)) than on unplanted soils (6.27-7.24mg(1-n)L(n)kg(-1)). In unplanted soils, vertisol adsorbed more endosulfan than lixisol. From the pot experiments, the estimated half-lives of endosulfan in unplanted soils (40.6 to 43.1days) were higher than in planted soils (34.5 to 40.6days) containing a greater number of endosulfan-degrading microorganisms. Six months after treatment, endosulfan was not detected in soils. The effectiveness of vetiver in promoting adsorption and the disappearance of endosulfan in both studied soils should be validated on the cotton plot scale in Burkina Faso.

Abstract

International audience; Lowland rice fields of West Africa (Ivory Coast) and South Asia (Thailand) are affected by ferrous toxicity or salinity, respectively, and their soil waters contain large amounts of ferrous iron, depending on reducing irrigation condition and suggesting occurrence of bacterial reducing processes. To determine the involvement, dynamic and activities of bacterial communities in Fe(III) reduction and mobilization during anaerobic degradation and mineralization of soil organic matter (SOM), different experiments and analyses have been performed. Results demonstrated that the utilization of SOM as sole carbon, nutrient and energy sources favored the presence of large bacterial communities: facultative anaerobic and anaerobic bacteria, Fe(III)-reducing bacteria (FeRB) (fermentative and Fe respiring), sulfate reducing bacteria (SRB) which are involved in carbon, nitrogen, iron and sulfur cycling. The larger functional diversity is observed in the Ivory Coast paddy soils containing larger amounts of organic matter and sulfur compounds. These communities contained complementary populations (chemoorganotrophic, chemolitotrophic, aerobic, facultative anaerobic and anaerobic) that can be active at different steps of iron solubilization with simultaneous organic matter mineralization. Our results indicate that the pH controlled by bacterial activity, the nature much more than the content of organic matter, and consequently the structure and activity of bacterial communities influence significantly the availability and dynamic of iron in paddy fields which affect the soil quality.

Abstract

International audience; The chemical compositions of the essential oils of Ocimum canum Sims (Lamiaceae) areal part cultivated in Togo were investigated by GC-MS and tested for possible insecticidal activity against the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytinae) under laboratory. Eighteen constituents (98.5 % of the total oil) were identified in the volatile oil of O. canum leaf. The main constituents found in the oil were terpineol-4 (34.7 %), linalool (22.7 %), gamma-terpinene (7.3 %), trans-thujan-4-ol (5.9 %), trans-alpha-bergamotene (4.9 %) and caryophyllene (4.6 %). Other components were also identified by at minor concentrations ranging from 0.12 % (Thymol) to 2.7 % (Limonene). In the insecticidal activity test, crude essential oil of O. canum emulsions of exhibited adulticidal activity against coffee berry borer and response was being dose-related. The LD50 were 320 ppm for O. canum essential oil and 450 ppm for endosulfan and the conventional insecticide used as standard, respectively. The results indicate that the O. canum essential oil has a potential insecticidal activity and can be used as active ingredient in natural and sustainable pesticide within an Integrated Pest Management approach to combat the coffee berry borer.

Abstract

International audience; In laboratory experiments, lepidocrocite reduction by the dissimilatory iron reducing bacteria, Shewanella putrefaciens, is known to generate extra-cellular iron (II-III) minerals as green rust (GR) or magnetite. However, the parameters controlling the formation of these minerals remain unclear. In order to identify these parameters, reduction experiments were designed to obtain either GR or magnetite with methanoate as electron source and lepidocrocite (γ-FeOOH) as the electron acceptor. The mineral products were monitored by XRD analyses, and the rate of reduction and Eh/pH evolution were assessed during GR and magnetite formation. The only difference between the two conditions lies with the inoculum size: magnetite is systematically produced by the treatments containing the lowest cell density (5 × 10 CFU mL) and GR1(CO3 ) precipitated in the highest cell density (2 × 10 CFU mL). We showed that 100 μ M of anthraquinone 2,6 disulfonate (AQDS) did not influence the nature of the biogenic minerals. In addition, based on thermodynamic calculations, we observed that the Eh/pH paths in the Pourbaix diagram depend on the nature of the minerals formed, i.e. GR1(CO3 ) or Fe3O4. However, the Pourbaix diagram cannot be used to forecast unambiguously the nature of these minerals. We propose that a close association of bacterial cells and γ-FeOOH particles occurs during the Fe(III) mineral reduction. We hypothesis that this aggregation influences the bio-reduction rate and is related to the nature of the biogenic mineral precipitated in the reduction media.

Abstract

Dithienylethylene unit have been incorporated in a molecular wire. Incorporated in a Self Assembled Monolayer and tested by Scanning Tunnelling Microscopy, the molecule has been shown to have a blinking contrast. Redox properties of model compounds have been explored in order to explain this feature: all molecules can be oxidized and the resulting radical cations may undergo ring closure or opening depending on its substituents.

Abstract

Results are given of a comparison of catches of adult Trichoptera in a light trap with collections of larvae on artificial substrates in the Upper Rhone near Lyons. Except for Hydropsychidae and some Polycentropodidae, the light trap is more effective than artificial substrates. However, results obtained from a light trap do not give informations on the distribution of Trichoptera within the habitat and so other techniques must be used in addition.
