ジャーナル フリーExamining some equations presented by several authors for describing the distancedispersal rate relationship of insects and plant diseases, the present authors concluded that the following equations are most appropriate to represent the distance-dispersal rate relationships : [numerical formula] Here, y means number of individuals recaptured per sample unit taken from a point with distance r from the release point, S means πr^2 and A, B and B' are constants. It was demonstrated that, the linear relationship between log y and S (or r^2) reflects the result of random dispersal which was well described by the bivariate normal distribution. These simple equations are, therefore, useful to judge whether the dispersal of an insect population in question occurred at random.抄録全体を表示PDF形式でダウンロード (505K) -

ジャーナル フリーThe larvae of an unstable multivoltine strain in silkworms (Bombyx mori L.) are reared intermingled with those of a bivoltine strain in such a ratio as 1 : 1 or 1 : 2 in number almost under a constant condition. All the offsprings of the bivoltine strain (Kuroshima) in every breeding section are provided with the diapause character without exception. In the unstable mutivoltine strain (Daizo), however, the voltinism of the offsprings is greatly influenced by the mixed breeding. The ratio of the number of the moths which oviposit more diapause eggs than non-diapause ones to the number of the rest becomes conspicuously larger in Daizo in the case of the mixed breeding than in Daizo of the non-mixed breeding. The ratio of the total number of the diapause eggs to the non-diapause eggs shows itself to be of the same tendency. Diapause of insects is known to be controlled by day-length, temperature, food or population density, etc. The induction of the present diapause does not seem to be dependent upon any one of these factors, though the real causal factor remains unsolved.抄録全体を表示PDF形式でダウンロード (1368K) -

ジャーナル フリーWhen Ayu-fries which were motored far from Lake Biwa to Ueda under a long and heavy confinement are set free in a culture pond, they begin to exhibit a type of jumping movement-we call it "Released jumping"-towards the cascade of the water entrance. This jumping behavior is seen from about 45 minutes before sunrise to about 35 minutes after sunset on a fine day, when four modal peaks of the activity are recognizable. The present activity compared with that of feeding which was observed by ISHIDA (1964) in a pond, the former seems to be in a regular reverse relation to the latter in each peak. The height of jumping is 62cm to 68cm on an average and the optimum current velocity for the activity is assumed to exist below 80cm/sec. Of the environmental factors, the sunlight intensity appears to be most influential, though it is considered that the activity is controlled primarily by some endogenous mechanism of the fish.抄録全体を表示PDF形式でダウンロード (840K) -

ジャーナル フリーIn the experimental populations of the three races of the Japanese crucian carp (Kin-, Gin- and Gengoro-buna) started with the larvae just hatched from one batch of eggs and fed with different kinds of food, the growth of the component fry was studied during four or five months in relation to feeding and schooling behaviour. 1. The order of increase in body size of Kin- to Gin- to Gengoro-buna was seen in the first two months. In this period the decrease in growth rate of Kin-buna exceeded that of other two races. The same order in body height was caused through a remarkable decrease in the ratio of height to length of the body at the developmental etap G in Kin-buna, which was not observed in the other two races. 2. All three races fed with Cladocera, trout pellets and slimeworms showed more or less good growth, but the growth rate of those fed with Cholrella was far less than when fed with other kinds of food. 3. Respiration rate of Kin- and Gin-buna was larger than that of Gengoro-buna, but Kin-buna showed far greater tolerance to low oxygen concentration than the others. 4. Schooling tendency of Kin- and Gin-buna became more indistinct as they became older, but the school of Gengoro-buna was observed still in the later course of growth. 5. In the mixed population of the three races, Gin-buna showed the largest growth rate of the three when food supply was limited.抄録全体を表示PDF形式でダウンロード (1742K) -

ジャーナル フリーIn den Gebieten vom inneren Kurobe, Tateyama-und Hakusan-Gebirge, gedeihen Zwergkieferngestrauche, das Vaccinieto-Pinetum pumilae, oberhalb der Waldgrenze ganz uppig. Alpine Heiden, das Arcterio-Loiseleurietum OHBA, befinden sich hier auch als eine Dauergesellschaft am Standorte, wo der Windsto B das Vorkommen der ersten Gesellschaft verhindert. Von der ersten kann man zwei Subassoziationen, cetrarietosum und rubetosum pedati, und von der zweiten Subassoziation noch vier Varianten kennzeichnen. Diese Assoziation gehort zum Verband Pinion pumilae, der Ordnung Pinetalia pumilae und der Klasse Vaccinio-Piceetea japonica. Das Arcterio-Loiseleurietum soll sich mit dem Loiseleurieto-Cetrarietum von den Schweizer Alpen in die neue Klasse der Loiseleurio-Cetrarietea ordnen lassen. Das Verband Arcterion wird sonst das Caricetoum Doenitzii im Berg Gassan umfassen. Das Vaccinio-Pinetum ist eine Pflanzengesellschaft, worin immergrune Nadelstrauche mit Bryochamaephyten vergesellschaftet sind : dagegen liefert das Arcterio-Loiseleurietum einen Platz zum Zusammenleben von Zwergstrauchen mit Strauchflechten. Floristisch erhalt das erstere die typische Verbindung von Pinaceen und Erikaceen von der Vaccinio-Piceetea, aber fur das letztere spielen Erikaceen und Cypteraceen eine Hauptrolle. Beide Assoziationen sind sonnenliebend und gegen die Schneedauen empfindlich, aber die letztere ertragt einen starkeren WindstoB. Das Vaccinieto-Pinetum pumilae ist durch den Eisenpodsol unterlegt, dagegen ist der Boden unter dem Arcterio-Loiseleurietum noch unreif. Die Xeroserie entspringt zuerst aus der Ryrophora-Rhizocarpon-Flechten-Gesellschaft auf den Felsen und dann tritt durch das Arcterio-Loiseleurietum und die Subassoziation cetrarietosum bis auf rubetosum pedati vom Vaccinieto-Pinetum pumilae ein. Die Sasa kurilensis Variante entsteht von der Torfserie aus dem Faurieto-Caricetum blepharicarpae. Die Sukzession ist tatsachlich kaum weiter fort zu erwagen.抄録全体を表示PDF形式でダウンロード (2045K) -
