    The spermatogenetic process in Barbus longiceps, Capoeta damascina and their natural sterile hybrid (Teleostei, Cyprinidae) (1996)

    Notes: Testicular ultrastructure was studied in Barbus longiceps, Capoeta damascina and their natural hybrid. The testes of these teleosts belong to the unrestricted or lobular type. Germ cell morphology is similar in the parental males. In the hybrid, spermatogenesis does not extend beyond the pachytene of the first meiotic division, probably due to the unsuccessful pairing of the homologous chromosomes. Hybrid testes are occupied mainly by degenerating primary spermatocytes, at the leptotene and pachytene stages. In both parents and the hybrid, Sertoli and Leydig cells are characterized by the presence of granular endoplasmic reticulum and of mitochondria with tubular cristae. Due to the arrest of spermatogenesis, the male germ cell protective barrier is absent in the hybrid. Germ cell nuclear size was measured by a computerized analysis system, using light-microscopy images. In the parents and the hybrid, germ cells attain a uniform inter-individual nuclear size when they reach the first meiotic prophase. The nuclear size of primary spermatocytes is similar among the three groups of fish, possibly reflecting their close genetic relationship.

    Fusarium resistance in Gladiolus: Selection in seedling populations (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 116 (1997), S. 0 
    Details
    ISSN: 1439-0523
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: A test to select Fusarium resistant seedlings of Gladiolus is described. Seedlings of 37 populations, obtained from an incomplete diallel between eight parents with different levels of Fusarium resistance, were used. Significant differences in Fusarium infection between and within populations were detected. Most of the descendants selected had a resistant G. dalenii genotype as one of the parents. The resistance level of the parents was associated with the general combining ability for Fusarium resistance based on the seedling test. Implications for resistance breeding are discussed.

    Notes: Environmental data often have features that are distinct from data in other branches of science. These features include spatial and/or temporal auto-correlation, natural heterogeneity, measurement errors, small sample sizes, and simultaneous existence of different types and qualities of data. Realistic environmental modeling requires simulation procedures that account for all of these features. In this study, a model of uncertainty analysis, BUDA, is used to account for the noted features and provide a unified framework for quantification, propagation, and reduction of uncertainty. The BUDA model is used to analyze the development of a chloride plume around an old landfill to the year 2020. This article describes the different components of BUDA as they relate to the landfill application.

    Stomatal control by fed or endogenous xylem ABA in sunflower: interpretation of correlations between leaf water potential and stomatal conductance in anisohydric species (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 19 (1996), S. 0

    Notes: The stomatal conductance of several anisohydric plant species, including field-grown sunflower, frequently correlates with leaf water potential (φ1), suggesting that chemical messages travelling from roots to shoots may not play an important role in stomatal control. We have performed a series of experiments in which evaporative demand, soil water status and ABA origin (endogenous or artificial) were varied in order to analyse stomatal control. Sunflower plants were subjected to a range of soil water potentials under contrasting air vapour pressure deficits (VPD, from 0.5 to 2.5 kPa) in the field, in the glasshouse or in a humid chamber. Sunflower plants were also fed through the xylem with varying concentrations of artificial ABA, in the glasshouse and in the field. Finally, detached leaves were fed directly with varying concentrations of ABA under three contrasting VPDs. A unique relationship between stomatal conductance (gs) and the concentration of ABA in the xylem sap (xylem [ABA]) was observed in all cases. In contrast, the relationship between φ1 and gs varied substantially among experiments. Its slope was positive for droughted plants and negative for ABA-fed whole plants or detached leaves, and also varied appreciably with air VPD. All observed relationships could be modelled on the basis of the assumption that φ1 had no controlling effect on gs. We conclude that stomatal control depended only on the concentration of ABA in the xylem sap, and that φ1 was controlled by water flux through the plant (itself controlled by stomatal conductance). The possibility is also raised that differences in stomatal ‘strategy’ between isohydric plants (such as maize, where daytime φ1 does not vary appreciably with soil water status) and anisohydric plants (such as sunflower) may be accounted for by the degree of influence of φ1 on stomatal control, for a given level of xylem [ABA]. We propose that statistical relationships between φ1 and gs are only observed when φ1 has no controlling action on stomatal behaviour.

    Absolute and relative locations of similar events with application to microearthquakes in southern Iceland (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 123 (1995), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: It is well known that similar earthquakes, i.e. earthquakes having almost identical waveforms, allow extremely accurate relative timing of the seismic arrivals. This has traditionally been used for achieving accurate relative locations of clusters of similar earthquakes. The arrival time differences between similar events depend not only on their relative location but also on the absolute location of the group. Moving a pair of events 200 m while retaining their relative locations can cause a 1 ms change in the time difference between the first arrivals of the events at a station 6 km distant. A change in time difference of 1ms can easily be estimated by cross-correlating the waveforms of the two earthquakes. We use the accurate relative timings to improve absolute locations of groups of similar events, as well as to obtain extremely accurate relative locations. The absolute locations from relative timings are expected to have errors that are independent of the errors associated with locations based on absolute arrival time observations.We analyse data from five earthquake sequences, comprising a total of 96 earthquakes, recorded by a regional network in southern Iceland. One of the clusters is located within the on-land spreading ridge in south-western Iceland, and the other four are within the South Iceland seismic zone, a transform zone between overlapping branches of the spreading ridge. The events vary in magnitude between Ml−0.3 and 2.8. After determining the absolute and relative locations of each swarm, we estimate the orientation of a best-fitting plane through the hypocenters. The mean distance of events from a best-fitting plane varies between 4 and 15 m for the five swarms. This is comparable to the formal error estimates for the relative locations. Together with (non-unique) fault-plane solutions, the relative locations constrain the fault planes and the type of faulting. Faulting within the nascent transform zone in southern Iceland is predominantly strike slip on near-vertical N-S striking planes, in agreement with the orientation of mapped earthquake fractures in the area. The earthquakes within the spreading zone clearly define a fault plane striking parallel to the ridge and dipping 63°. Each group of similar events probably represents repeated slip on the same fault.

    Reinterpretation of the RRISP-77 Iceland shear-wave profiles (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 126 (1996), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005

    Notes: Two shear-wave profiles, E and G, collected during the 1977 Reykjanes Ridge Iceland Seismic Experiment have played an important role in models of the Icelandic crust. They were originally interpreted as indicating very low shear-wave velocities and abnormally low shear-wave quality factors in the 10–15 km depth range. These attributes, which are indicative of near-solidus temperatures, were used to support the hypothesis that the crust of Iceland is relatively thin (10–15 km) and underlain by partially molten material. More recent seismic data, however, contradict this hypothesis and suggest that the crust is thicker (20–30 km) and cooler. A re-examination of the RRISP-77 data indicates that the low shear-wave velocities are artefacts arising from source static anomalies (in the case of profile G) and misidentification of a secondary shear phase, SmS, as S (in the case of profile E). Furthermore, the attenuation occurs at ranges when rays from the shots pass near the Askja (profile E) and Katla and Oraefajokull (profile G) volcanoes. It may therefore have a localized source, and not be diagnostic of Icelandic crust as a whole. This new interpretation of the RRISP-77 shear-wave data is consistent with models having a thick, cold crust.

    Notes: The extended BBCH scale is a system for a uniform coding of phenologicaliy similar growth stages of all mono- and dicotyledonous plant species, based on the well known cereal code of Zadoks et al. (1974). The BBCH key is it decimal system, with 10 principal growth stages and up to 10 secondary ones, starting with seed germination, sprouting of perennials, progressing through leaf production and extension growth to flowering and senescence. Therefore, it can also be a suitable tool to define the growth stages of different weed species. To encourage further use of the BBCH scale in weed research, definitions of the codes have been more closely adapted to weeds. Possible problems are discussed and guidelines for correct use are given.

    Notes: It is proved that horizontally stratified media, the various materials of which do not differ in their Poisson number, can be considered as isotropic for reflections of a small dip when taking into account quasi-longitudinal waves which have to be reckoned with in practice. Approximating the surface of the wave by an ellipsoid would, however, result in considerable errors.Moreover, curves are presented allowing practical calculations for steeper dips to be made.
