    In:  Supplement to: Emiliani, Cesare (1954): Pleistocene temperature variations in the Mediterranean. Quarternaria, 2, 87-97
    Publication Date: 2024-06-26
    Description: For temperature investigations, a core in the Mediterranean Sea (No 189 of the Swedish Deep-Sea Expedition 1947-1948) was sampled at approximately 10 m intervals. Globigerina dubia, G. inflata and Globigerinoides rubra were seperated from each sample and their test were investigated for stable oxygen isotopic measurement. Oxygen isotopic analysis showed the following: 1) Ten stages are indicated. 2) The temperature minimum of stage 2 corresponds to a racliocarbon age of 17,200 years. 3) Temperature maxima of odd stages are about equal to the modern August mean, except that of stage 5 which is considerably higher and, probably reflects the influx of ice melt water. 4) Temperature minima of even stages are all very low, especially that of stage 2, and reflect conditions similar to those now prevailing around Newfoundland. 5) The temperature record indicates that during most of the time covered by the core, the Mediterranean was cooler than at present and that conditions similar to the present occurred only during comparatively short intervals. 6) Minor temperature fluctuations occur, especially in the warmer stages, which are of doubtful significance. 7) An average rate of sedimentation of 4.3 cm/1000 years is indicated for the whole core.

    In:  Supplement to: Kröll, Victor (1953): Vertical Distribution of Radium in Deep-Sea Sediments. Nature, 171(4356), 742-742, https://doi.org/10.1038/171742a0
    Publication Date: 2024-06-26
    Description: The surprisingly high content of radium in certain deep-sea sediments discovered nearly fifty years ago by J. Joly remained unexplained until 1937, when H. Pettersson suggested an ocean-wide precipitation of ionium from sea water on to the ocean bottom as its origin. Extensive radium measurements on deep-sea cores raised by the Swedish Deep-Sea Expedition carried out in this institute by Pettersson, T. Bernert and me did not confirm the regular vertical distribution of radium reported by other workers. An expected rise in radium content from moderate values in the uppermost surface layers to a maximum corresponding to a radioactive equilibrium between precipitated ionium and ionium-supported radium generally occurred; but the maximum was not followed by the theoretical exponential decline downwards governed by the rate of decay of ionium, to 50 per cent in 83,000 years, to 25 per cent in 166,000 years, etc. Instead, a number of secondary maxima of radium content separated by equally pronounced minima were observed (see graph), which could not well be explained as due to intervening changes in the rate of total sedimentation. Another explanation offered was that ionium and radium are not in radioactive equilibrium; that is, the assumption underlying the use of measurements of radium as indicating the concentration in the same layer of its mother element is unjustified.

    Description: Compared with their New World relatives of the subfamily Cyprinodontinae, the Old World Cyprinodonts are but little known. However, some interesting accounts on Turkish species, discovered by Kosswig, S\xc3\xb6zer and Aksiray, have recently been published. Besides the species known, several new forms and species are described.\nWhile compiling an account on these fishes suitable for the home aquarium (Hoedeman & Bronner, 1950\xe2\x80\x941951), we felt some characters need reexamination, not only of Aphanius, but also of the North African genus Tellia which is said to differ from Aphanius only in the absence of ventral fins.

    Description: Corophium arenarium was first described by CRAWFORD in his excellent review of the entire genus, in 1937. In the description, the author expressed his doubt already whether it might be a distinct species or merely a variety of C. volutator. CRAWFORD\xe2\x80\x99S observations on the variation of the number of spines on antenna II, segment 4 and 5, suggest that it is only a variety.\nCHEVAIS, 1937, does not give a definite opinion, whether he considers the species distinct from each other or not. For biometrical reasons, as well for reasons of variation observed by other authors, he suggests, however, that C. volutator and C. arenarium are only local races of one species.

    Description: The distribution of fresh-water fishes like that of other groups, has been widely utilized by zoogeographers, but with widely divergent acumen and success. At one extreme are those non-ichthyologists who have uncritically utilized for evidence certain groups whose distribution happens to support whatever theory they may be espousing. At the other extreme is the work of careful ichthyologists like DE BEAUFORT (1913) and REGAN (1922) whose thorough knowledge of the groups with which they are working demands the most careful consideration of their conclusions.\nHowever, no zoogeographer who utilizes the evidence of diverse groups can be familiar at first hand with all of them, and the difficulty facing such workers is that of seeking out the really dependable evidence in those groups he does not know well. Aside from the difficulty of selecting dependable authorities or systematic works, the zoogeographer desiring to use the evidence of fresh-water fishes has another troublesome matter to contend with. This is the differing tolerance of salt-water exhibited by different groups of fresh-water fishes. As one example, and one which has frequently troubled zoogeographers, we may mention the Galaxiidae, fresh-water fishes of Southern South America, Africa, Australia, and New Zealand, whose distribution has been held by some to be evidence for continental drift or southern intercontinental land-bridges. Ichthyologists now know that these fishes are, as a group, salt-tolerant and possibly either anadromous or catadromous, and that they are not really strong evidence for continental connections simply because it seems possible that they may cross ocean barriers.

    Description: For certain reasons I wished to train a young chimpanzee to choose from two similar boxes the one characterised by the ticking of a metronome inside it.\nMy subject was a young male chimpanzee (Pan leucoprymnus Lesson), approximately three years old, Tommy by name. He was a good-natured chap, quite tame, and already for some years in captivity. When we knew each other a little better, he would welcome me every morning with a hearty \xe2\x80\x9cuhuh\xe2\x80\x9d, as soon as he heard my steps, and after the experiments of the day we would take leave by shaking hands as old friends. Tommy was rather lazy and not so playful as most young chimpanzees, but this quality made working with him easier and more regular. With a few exceptions it did not give much trouble to make 50\xe2\x80\x9460 trials with him each day.
