Nuevos datos sobre algunas especies de Hemeróbidos de la península Ibérica e islas Canarias, incluyendo una nueva especie invasora de origen neotropical en Portugal (Insecta, Neuroptera, Hemerobiidae)

New data on the distribution, biology and phenology of 25 brown lacewings species (Insecta, Neuroptera: Hemerobiidae) of Iberian and Canaries fauna are given. The species Hemerobius bolivari Banks, 1910, widely distributed in the Neotropical Region, is recorded for the first time in Europe as a new invasive species, from specimens collected on Thaumastocoris peregrinus Carpintero & Dellapé, 2006 (Hemiptera: Thaumastocoridae) colonies on Eucalyptus in Lisbon (Portugal). This brown lacewing species, along with Sympherobius gayi Navás, 1910, also known from South America, is the second invasive species of neotropical origin, belonging to this family, that is recorded in the Iberian Peninsula, both from Portugal. We also mention several species that have been seldom recorded in the Iberian Peninsula, and among them Wesmaelius ravus (Withycombe, 1923) is recorded for the second time in the Iberian Peninsula, now from Sierra Nevada (Granada). From samplings made in southern Spain (Malaga, Granada) Micromus angulatus (Stephens, 1836) shows activity as imagoes during winter time (the entire year in the Iberian Peninsula, including this area), and these data seem also to confirm its link to grass vegetation.Se anotan nuevos datos sobre la distribución, biología y fenología de 25 especies de hemeróbidos (Insecta, Neuroptera: Hemerobiidae) de las Faunas Ibérica y Canaria. La especie Hemerobius bolivari Banks, 1910, ampliamente distribuida por la Región Neotropical, se cita por primera vez de Europa como una nueva especie invasora, a partir de ejemplares recolectados en colonias de Thaumastocoris peregrinus Carpintero y Dellapé, 2006 (Hemiptera: Thaumastocoridae:) sobre Eucalyptus en Lisboa (Portugal). Esta especie, junto a Sympherobius gayi Navás, 1910, también originaria de Sudamérica, es la segunda especie invasora de origen neotropical que de esta familia se cita en la Península Ibérica, en este caso también de Portugal. Se mencionan varias especies que han sido muy escasamente citadas en la Península Ibérica, y entre ellas destaca Wesmaelius ravus (Withycombe, 1923), que se cita por segunda vez en la Península Ibérica, en este caso de Sierra Nevada (Granada). A partir de muestreos realizados en el sur de España (Málaga, Granada), se desprende actividad en los imagos de Micromus angulatus (Stephens, 1836) en los meses de invierno (a lo largo de todo el año en la Península Ibérica, incluyendo esta zona ibérica), y estos datos también parecen corroborar su vinculación con la vegetación arvense

Starch enzymatic hydrolysis, structural, thermal and rheological properties of pigeon pea (Cajanus cajan) and dolichos bean (Dolichos lab-lab) legume starches

Producción CientíficaCajanus CajansandDolichos lab-lablegume starches from Argentine cultivars were investigated under atechnological and nutritional point of view. Their physico-chemical, structural, thermal and the rheologi-cal properties of their gels were evaluated. Rice (RS) and potato (PS) starches were included as references.In vitrodigestibility from Englyst method was also evaluated. Legume starches had the highest amylosecontent and the most stable chemical structure. Their rapidly digestible starch and starch digestibility rateindex were very low, similar to PS, and fivefold lower than RS. They had a much higher slowly digestiblestarch content than PS. Legume starches showed the highest gel stability versus heating and stirring andan intermedium pasting temperature between RS and PS. They formed viscoelastic gels at 6% concentra-tion with stronger elastic-like behaviour and higher yield stress than references. Our results indicate theselegumes represent an efficient starch source to provide tailor-made properties to food/industrial applica-tions.Ministerio de Economia y Competitividad and the European Regional Development Fund (FEDER) (AGL2015-63849-C2-2-R)Junta de Castilla y Leon/FEDER VA072P17Universidad Nacional del Nordeste, Argentina (PI: 16-F017

Solvothermal synthesis of lanthanide-functionalized graphene oxide nanocomposites

We propose a facile approach to the preparation of graphene oxide (GO) composites with lanthanide (Ln) oxide/hydroxide nanoparticles (Ln = La, Eu, Gd, Tb) under relatively mild conditions by two different procedures of solvothermal synthesis. The mechanism of GO-Ln nanocomposite formation is thought to involve the initial coordination of Ln3+ ions to the oxygen-containing groups of GO as nucleation sites, followed by f Ln2O3 and Ln(OH)3 nanoparticle growth. The nanocomposites obtained preserve the intrinsic planar honeycomb-like structures of graphene as proven by the typical G and D bands in the Raman spectra. Fourier-transform infrared and X-ray photoelectron spectroscopy confirm the interaction between oxygen-containing groups of GO and Ln ions. The size and distribution of Ln oxide/hydroxide nanoparticles on GO sheets, estimated from scanning and transmission electron microscopy images, vary broadly for the different lanthanides. The size can span from sub-nm dimensions for Eu oxide to more than 10 μm for Eu hydroxide nanoparticles. The most homogeneous distribution of Ln oxide/hydroxide nanoparticles was found in La-containing composites. Thermogravimetric analysis demonstrated that all the GO-Ln nanocomposites are thermally less stable, by up to 30 °C than pristine GO.</p

Proanthocyanidins inhibit Ascaris suum glutathione-S-transferase activity and increase susceptibility of larvae to levamisole and ivermectin in vitro

Proanthocyanidins (PAC) are a class of plant secondary metabolites commonly found in the diet that have shown potential to control gastrointestinal nematode infections. The anti-parasitic mechanism(s) of PAC remain obscure, however the protein-binding properties of PAC suggest that disturbance of key enzyme functions may be a potential mode of action. Glutathione-S-transferases (GSTs) are essential for parasite detoxification and have been investigated as drug and vaccine targets. Here, we show that purified PAC strongly inhibit the activity of both recombinant and native GSTs from the parasitic nematode Ascaris suum. As GSTs are involved in detoxifying xenobiotic substances within the parasite, we hypothesised that this inhibition may render parasites hyper-susceptible to anthelmintic drugs. Migration inhibition assays with A. suum larvae demonstrated that the potency of levamisole (LEV) and ivermectin (IVM) were significantly increased in the presence of PAC purified from pine bark (4.6-fold and 3.2-fold reduction in IC50 value for LEV and IVM, respectively). Synergy analysis revealed that the relationship between PAC and LEV appeared to be synergistic in nature, suggesting a specific enhancement of LEV activity, whilst the relationship between PAC and IVM was additive rather than synergistic, suggesting independent actions. Our results demonstrate that these common dietary compounds may increase the efficacy of synthetic anthelmintic drugs in vitro, and also suggest one possible mechanism for their well-known anti-parasitic activity

Statistics of the main purse seine fleets fishing in the Indian Ocean (1981-2008).

This document presents a summary of the statistics of French, Spanish, Italian, Seychelles and EU related NEI purse seine fleets fishing in the Indian Ocean since 1981: effort, catch by species and fishing type (log and free swimming schools), catch per unit of effort, sampling and mean weights for the main species. Since 2002, data from the European fleet (France and Spain) are collected within the framework of the EU “Data Collection Regulation” (DCR, Reg. 1543/2000 and 1639/2001), followed in 2008 by the “Community framework for the collection, management and use of data in the fisheries sector and support for scientific advice regarding the Common Fisheries Policy” (DCF, Reg 199/2008 and 665/2008). Data from other fleets are collected by SFA (Seychelles Fishing Authority). Data processing (species composition and size distribution) is done collectively for the whole fishery

Effects of environmental variables on the distribution of juvenile cubomedusae Carybdea marsupialis in the coastal Western Mediterranean

[EN] Relationships between environmental factors and oscillations in jellyfish abundance, especially in the early life stages, could help to interpret past increases and also predict scenarios in a changing future. For the first time, we present cubozoan spatial and temporal distributions in the earliest stages and their relationships with different factors. Abundances ofCarybdea marsupialismedusae showed high interannual variability from 2008 to 2014 along the Denia coast (SE Spain, W Mediterranean). During 2015, samples were collected from 11 beaches along 17 km of coastline, 8 times from January to November in order to determine the effects of environmental factors on the distribution of juvenileC.marsupialis. Juveniles (<= 15 mm diagonal bell width) were present from May to July, with more sampled near shore (0-15 m). Most of them occurred in June when their numbers were unequal among beaches (average 0.05 ind m(-3), maximum 6.71 ind m(-3)). We tested distributions of juveniles over time and space versus temperature, salinity, nutrients (N, P and Si), chlorophyll-a(Chl-a), and zooplankton abundance. Temperature and cladocerans (zooplankton group) were significantly positively correlated with juvenile distribution, whereas Chl-aconcentration was weakly negative. By contrast, in 2014, high productivity areas (Chl-aand zooplankton) overlapped the maximum adult abundance (5.2 ind m(-3)). The distribution of juveniles during 2015 did not spatially coincide with the areas where ripe adults were located the previous year, suggesting that juveniles drift with the currents upon release from the cubopolyps. Our results yield important insights into the complexity of cubozoan distributions.This study has received funding through European Commission's LIFE programme [LIFE08 NAT ES64 CUBOMED.eu to C.B. from the Alicante University and V.L.F. from the Institute of Marine Science, CSIC, Spain], and from the D.G Sostenibilidad de la Costa y el Mar from the Spanish Ministry of Agriculture, Food and the Environment, the Fundacion Biodiversidad, and the D.G.

Optical Light Curve of the Type Ia Supernova 1998bu in M96 and the Supernova Calibration of the Hubble Constant

We present the UBVRI light curves of the Type Ia supernova SN 1998bu which appeared in the nearby galaxy M96 (NGC 3368). M96 is a spiral galaxy in the Leo I group which has a Cepheid-based distance. Our photometry allows us to calculate the absolute magnitude and reddening of this supernova. These data, when combined with measurements of the four other well-observed supernovae with Cepheid based distances, allow us to calculate the Hubble constant with respect to the Hubble flow defined by the distant Calan/Tololo Type Ia sample. We find a Hubble constant of 64.0 +/- 2.2(internal) +/- 3.5(external) km/s/Mpc, consistent with most previous estimates based on Type Ia supernovae. We note that the two well-observed Type Ia supernovae in Fornax, if placed at the Cepheid distance to the possible Fornax spiral NGC 1365, are apparently too faint with respect to the Calan/Tololo sample calibrated with the five Type Ia supernovae with Cepheid distances to the host galaxies.Comment: AAS LaTeX, 20 pages, 4 figures, 6 tables, accepted for publication in the Astronomical Journal.
