    Notes: The desi and kabuli chickpeas are characterized, among other things, by their seed coats being thicker in the desi than in the kabuli type. The inheritance of seed coat thickness, and its relation to flower colour and seed size, was studied. Seed coat thickness exhibits monogenic inheritance, the thin kabuli seed coat being the recessive character. Linkage was found between seed coat thickness and flower colour, the recombinant fraction being 0.19. No relationship was found between seed coat thickness and seed size. The role of these characters in the evolution of the chickpea is discussed.

    Notes: The inheritance of resistance to fusarium wilt race 0 of chickpea and linked random amplified polymorphic DNA (RAPD) markers were studied in two F6:7 recombinant inbred line (RIL) populations. These RILs were developed from the crosses CA2156 × JG62 (susceptible × resistant) and CA2139 × JG62 (resistant × resistant), and were sown in a field infected with fusarium wilt race 0 in Beja (Tunisia) over 2 years. A1:1 resistant to susceptible ratio was found in the RIL population from the CA2156 × JG62 cross, indicating that a single gene with two alleles controlled resistance. In the second RIL population (CA2139 × JG62) a 3:1 resistant to susceptible ratio indicated that two genes were present and that either gene was sufficient to confer resistance. Linkage analysis showed a RAPD marker, OPJ20600, linked to resistance in both RIL populations, which is present in the resistant parent JG62.

    Notes: Five pairs of near isogenic lines (NILs) for the gene for single vs. double pod were used to study the effect of this character on yield and its components (seeds per plant, yield per plant and seed weight). The NILs were sown in 2 years at five locations in ihe first year and four locations in the second. Combined analysis of variance was applied to t he data and no significant differences between isolines were found, but there were significant genotype– location interaction effects for yield and seeds per plant. For both characters the double–podded lines were more stable than the single–podded lines. Although there were significant differences between the five genotypes lor yield per planl and seed weight, the differentes between single– and double–podded lines were almost nil. The results indicate that the double–pod gene has a positive effect on the stability of yield and is not linked to any other gene responsible Tor seed size in chickpea

    Notes: The genetics of resistance of common vetch (Vicia sativa L.) to broomrape (Orobanche crenata Forsk.) was studied for two years by using the P1, P2, F1, BC1, BC2, F2 F3, and F4 generations obtained from crosses between resistant and susceptible lines. Resistant lines were selected by screening a world collection m a naturally infested plot. Resistance was tested both under field and greenhouse conditions. The best index to measure resistance was the number of emerged broomrapes per host plant. The results fit the additive-dominance model. The main component of the variation was additivity; dominance and interaction effects seemed to depend on the environment. When dominance is expressed, a low number is dominant over a high number of broomrapes per host plant.

    Notes: A collection of 51 accessions of Phaseolus vulgaris L. from N.W. of the Iberian Peninsula was evaluated for phenological, morphological, and agronomic characters for two years to study patterns of variation. Data were subjected to cluster analysis by variables choice, and six groups could be identified. These in turn corresponded to each previously described races ‘Nueva Granada’ and ‘Chile’ of South American origin, and races ‘Durango’ and ‘Mesoamerica’ of Middle American domestication center. Accessions falling in race ‘Nueva Granada’ had two distinct gene pools.

    High effusion rates of the Cordón Caulle 2011-12 eruption (Southern Andes) and their relation with the quasi-harmonic tremor (2015)
    Wiley
    Details
    Publication Date: 2015-08-24
    Description: High effusion rates of intermediate-to-high-silica lavas seem to be less uncommon than previously thought, in particular during their initial eruptive stages. In this study, we report satellite-based time-averaged discharge rates for the 2011-2012 effusive phase at Cordón Caulle, which are well correlated with the evolution of the quasi-harmonic tremor, the most significant seismic signal after the initial explosive stage. Such a correspondence could become a key method for detection of the onset of effusive phases, especially in remote and/or very cloudy areas, supplying an additional tool for effective warnings and near real-time hazards appraisal.

    Histological alterations in the structure of the testis in tench (Tinca tinca) after exposure to 17 alpha-ethynylestradiol (2013)
    Wiley
    Details
    Publication Date: 2013-02-20
    Description: Environmental pollution with synthetic estrogens may pose a serious threat to reproduction of aquatic wildlife species. The current study describes the effects of 17α-ethynylestradiol (EE 2 ) on the structure of the testis in tench ( Tinca tinca ). Adult male tench were exposed to sublethal doses of EE 2 (50, 100, and 500 μg/Kg t.w.) under semistatic conditions for a period of 30 days. The condition factor (CF), testicular somatic index (TSI), and histology (including a morphometric analysis) of the testis were examined. No consistent differences were observed in the CF of EE 2 -exposed tench when compared with nonexposed fish. A significant decrease in TSI could only be observed at a 50 μg/Kg t.w. EE 2 dose (p 〈 0.05) when compared with the control group. The histopathology of the testis was associated with loss of normal tubular structure with increased doses of exposure, decrease of tubule number, degeneration in Sertoli and Leydig cells, increase in necrotic testicular cells including formation of syncytia structures and, finally, a high incidence of fish with early primary oocytes at 100 and 500 μg/Kg t.w. EE 2 . These results indicate that long-term exposure to EE 2 may produce clear negative effects on testicular structure in tench. © 2013 Wiley Periodicals, Inc. Environ Toxicol, 2013.

    Evaluation of the aerosol forcing efficiency in the UV erythemal range at Granada, Spain (2011)
    Wiley
    Details
    Publication Date: 2011-10-28
    Description: Atmospheric aerosols represent one of the most important components that attenuate solar radiation reaching the Earth's surface. The aerosol radiative forcing (ARF) at the surface is usually determined in the visible range of the solar spectrum. In contrast, there are few experimental works in the literature about the ARF in the ultraviolet (UV) region. Therefore, this paper focuses on quantifying the aerosol forcing efficiency in the UV erythemal range (AFEery), ARF per unit of aerosol optical depth (AOD). Simultaneous UV erythemal irradiance (UVER) and AOD measurements recorded between January 2006 and December 2008 in Granada (Spain) were used. In addition, an empirical model is utilized to estimate the UVER values for an atmosphere with very low aerosol loads (clean conditions). The AFEery varies from −62 to −26 mW/m2 per unit of AOD at 380 nm when the solar zenith angle (SZA) changes from 20° to 55°, showing a strong influence of the SZA on AFEery. The variations of the aerosol size and absorption properties also cause significant changes of this variable. Thus, 1 μm aerosols (related to desert dust particles) produce significantly higher AFEery (in absolute values) than submicrometer particles (associated with urban or industrial aerosols). For instance, AFEery varies from −52 mW/m2 per unit of AOD for Angström exponents smaller than 0.5 to −29 mW/m2 per unit of AOD for Angström exponents higher than 1.5. In addition, the AFEery values are −59 mW/m2 per AOD unit for single-scattering albedos (SSAs) smaller than 0.85 and −28 mW/m2 per AOD unit for SSAs larger than 0.85, showing that stronger aerosol absorption (low SSA) leads to a larger surface forcing efficiency (in absolute values). All these results highlight the outstanding role that atmospheric aerosol plays in the modifying levels of UV radiation reaching the surface.

    Iodine chemistry in the Eastern Pacific marine boundary layer (2013)
    Wiley
    Details
    Publication Date: 2013-01-05
    Description: [1]  Observations of gas-phase iodine species were made during a field campaign in the Eastern Pacific marine boundary layer (MBL). The Climate and HAlogen Reactivity tropicaL EXperiment (CHARLEX) in the Galápagos Islands, running from September 2010 to present, is the first long-term ground-based study of trace gases in this region. Observations of gas-phase iodine species were made using Long Path Differential Optical Absorption Spectroscopy (LP-DOAS), Multi-axis DOAS (MAX-DOAS) and Resonance and Off-resonance Fluorescence by Lamp Excitation (ROFLEX). These measurements were supported by ancillary measurements of ozone, nitrogen oxides and meteorological variables. Selective halocarbon and ultrafine aerosol concentration measurements were also made. [2]  MAX-DOAS observations of iodine monoxide (IO) display a weak seasonal variation. The maximum differential slant column density was 3.8 × 10 13 molecule cm -2 (detection limit ~7 × 10 12 molecule cm -2 , or ~0.8 pptv). The seasonal variation of reactive iodine IO x (= I + IO) is stronger, peaking at 1.6 pptv during the warm season (February-April). This suggests a dependence of the iodine sources on the annual cycle in sea surface temperature, although perturbations by changes in ocean surface iodide concentration and solar radiation are also possible. An observed negative correlation of IO x with Chlorophyll indicates a predominance of abiotic sources. The low IO mixing ratios measured are not consistent with satellite observations, if IO is confined to the MBL. The IO x loading is consistent with the observed absence of strong ozone depletion and nucleation events, indicating a small impact of iodine chemistry on these climatically relevant factors in the Eastern Pacific MBL.
