    Notes: [Auszug] I HAVE read with interest Mr. Jones's letter on the results of the application of the logarithmic series and the index of diversity to his quadrat observations. I completely agree with him that the theoretical basis requires further study; as also does the field application to both animals and ...

    Notes: [Auszug] THERE have recently been two attempts to study the problem of random sampling from a mixed population in which all the constituent groups are not equally abundant. R. A. Fisher1 studied the problem of random samples of a population of insects in which the species were not equally ...

    Notes: [Auszug] THE problem of the relation of insect life to X climate and weather conditions has always attracted naturalists, both from its scientific and its practical importance; but most of the early work was qualitative rather than quantitative and, owing to the complexity of the problem, little real ...

    A Physiological Basis for the ‘Optimum’ Level of Energy Expenditure (1962)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] Neither of these criteria has a real physiological basis. An objective and sound physiological basis for the optimum level of work would be the level of oxygen consumption, compared with the maximum oxygen intake, at which the rate of supply of oxygen by cardio-respiratory mechanisms to working ...

Average growth-rates (11 seedlings) of the fast-growing (· ·) and slow-growing (·- - -·) sides of the Striga radicle during curvature and subsequent straight growth The initial curvature in one plane was used in studying quantitative aspects of the movement. For this purpose seedlings were ...

    Nocturnal Activity of Black Flies (Simuliidae) (1964)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] As previous observations had not suggested night activity in Simuliidae on such a scale, criticisms were made that the flies captured in the trap were merely late individuals in a dusk flight, and that real activity did not extend for any long period during darkness. Trapping in Inverness-shire ...

    Notes: [Auszug] IN the second week of March Cannes was visited by falls of snow and degrees of cold far exceeding any of which there is previous record. The preceding part of the winter was of average mildness; the minimum thermometer having fallen below freezing only three times, as follows: December 2, 32°; ...

    Notes: [Auszug] SINCE my last communication (see NATURE, vol. xxvii. p. 110) the weather and the presence of moonshine has been unfavourable for views of the comet; but I have seen it, more or less distinctly, on seven nights, from November 22 to December 21. I will not take up your space with details, but ...

    Notes: [Auszug] FOR several mornings past we have had fine views of the comet, first seen in England by Mr. A. Common. I inclose a sketch taken this morning, as accurate as I could make it with materials at hand. It is chiefly remarkable (1) for the crescentic end of the tail, the lower or eastern horn ...

    Notes: [Auszug] IN the morning here the sky was clear, and the sun remarkably free from spots. I noticed only 4 small ones on the disk: quite a contrast to the monstrous appearance a month ago. Being neither equipped nor qualified for technical astronomical observations, I did not attempt to do more than ...
