    Notes: Abstract— The characteristics of male upland bullies (Gobiomorphus breviceps) and their nest sites were examined in two New Zealand streams as possible determinants of male reproductive success. There was no association between male size, nest site characteristics (depth, distance to shore, river velocity, nest rock size), and male reproductive success. Similarly, the male's parasite load had no detectable influence on reproductive success. Multiple regression analysis revealed that no combination of factors could explain the wide variation in male reproductive success. It may be that the unpredictable nature of the stream habitats of bullies has favored reduced choosiness in females, which could lead to an absence of correlations between male and nest characteristics and reproductive success.

    Notes: [Auszug] The keeper at Woburn Park informs us that mating occurs in July; but the stags begin the 'rounding up' of the hinds in June. Mating usually occurs at night. Parturition has been reported in early April, but the usual date is mid-April to May; the latest date recorded was in September, the latter ...

    Parasites, aggression and dominance in male upland bullies (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 47 (1995), S. 0

    Notes: The effects of the digenean trematode parasite Telogaster opisthorchis on aggression and competitive ability in male upland bullies (Gobiomorphus breviceps) were examined using mirror-image stimulation (MIS) techniques and dyadic contests for nest sites between pairs of males. Parasite load had no significant effect on male aggression or success in dyadic contests, nor was aggression a predictor of the likely winner of these contests. The results are discussed with relation to the role of parasites in male-male competition and to possible problems in using MIS techniques for studies on dominance and aggression in fish.

    The effect of sward height on the liveweight gain of farmed yearling red deer (Cervus elaphus) stags (1995)

    Notes: The effect of sward height on the liveweight gain of yearling farmed red deer stags grazing permanent upland pastures in the UK in two successive years is described. The swards received nitrogen fertilizer at a rate of 218 kg ha−1. Red deer stag calves, which had been weaned in September and housed over winter on a hay and concentrate diet to gain on average 57 g d−1 in year 1 and 75 gd−1 in year 2, grazed at one of fourmean sward heights of 4, 6, 8 and 10cm from the beginning of June until September. Liveweight gains were recorded over a period of 15 weeks. All animals were slaughtered and carcass weights were recorded after the end of the grazing period. Liveweight gains and final live weights and carcass weights were significantly (P〈0·05) lower on the 4-cm sward than on the other swards, but there were no differences between the performance of animals on the 6-, 8- and 10-cm swards.

    A system for rapid freezing of pasture samples in the field (1984)

    Notes: A system for rapid freezing and containment of pasture and forage samples in the field is described. Core temperatures of pasture samples of 2–5 kg mass can be reduced to below 0°C in a few minutes using liquified carbon dioxide in the ratio of 1 to 2 kg carbon dioxide to 1 kg of green plant material. Changes in the pH of the plant extract were very small (ca. 0 1 pH unit). The system is especially suitable for use in areas remote from normal laboratory facilities, where rapid freezing of herbage samples is essential.

    High structural quality Ga1−xInxSb/InAs strained-layer superlattices grown on GaSb substrates (1992)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Strained Ga1−xInxSb/InAs superlattices exhibiting a high degree of structural perfection have been grown on GaSb substrates. The superlattices display ideal, defect-free structure, to within the resolution limits of transmission electron microscopy (TEM) and high-resolution x-ray diffraction. Cross-sectional micrographs reveal the layers to be highly planar, regular, and coherently strained to the GaSb substrates. No crystalline defects were observable by TEM, despite an internal lattice mismatch of almost 2%. Planarity of the layers is confirmed by the presence of Pendellösung fringes in high-resolution x-ray diffraction, while the observation of numerous sharp satellite peaks indicates little or no interdiffusion within the superlattices. Observed x-ray diffraction is closely fit by simulations based on a kinematical model which accounts properly for the highly strained interfaces and absence of strict translational symmetry in the superlattice growth direction. Based on this fit, an InSb-rich character is assigned to the interfaces, yielding superlattice layer thicknesses and compositions that are in quantitative agreement with those derived from independent growth rate calibrations.

    The formation of a continuous amorphous layer by room-temperature implantation of boron into silicon (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Ion implantation of 60 keV boron into {100} silicon at medium beam currents (150 μA) was performed at 300–315 K over the dose range from 1 to 8×1016/cm2. Diffraction contrast and high-resolution phase contrast transmission electron microscopy (TEM) were used on plan-view and 90° cross-section samples to study the formation of a continuous amorphous layer as a function of increasing dose. Our TEM results show that, unlike implantation of Si with heavier ions where amorphization initially occurs at or around the projected range, the amorphization by high dose (〉5×1016/cm2) B+-implanted Si first occurs at and/or near the surface. It is proposed that the buildup of a high concentration of vacancies which inevitably occurs near the surface during high-dose B+ implantation is primarily responsible for the observed near-surface amorphization. Based on the results of this investigation and those available in the published literature, it appears that low temperature (slow recombination rate for point defects) and high beam current (high generation rate for point defects) implantation may result in the optimum conditions for amorphous layer formation with boron.
