The terrestrial larger fungi in the evergreen broad-leaved forest (Alliance Shiion Sieboldi) was observed plant-sociologically for five years (from 1967 to 1971). As the result, it was concluded that it is most suitable to divide the fungi according to the substratum into two groups of horizon H and A. 1) The total number of fungi species found in the forest is 107. The majority of the H-horizon species are saprophytic, while those of the A-horizon are for the most part mycorrhizal. 2) Fourteen fairy ring forming species were ascertained from the A-horizon group of which Russula nigricans, R. densifolia and R. lepida were the fungous dominants in this forest association. 3) These rings are observed to be closely associated with the dominant tree species : Shiia cuspidata or Cyclobalanopsis gilva. 4) The ring formation is almost restricted to gentle slopes (less than 30°). 5) Judging from the occurrence of the three dominants of Russula, the less steep is the slope, the more luxuriant becomes their occurrence. 6) The dominant three species of Russulae, belonging to the autumnal fungus flora have large and fleshy fruit bodies and occur in the season with highest soil temperature.

Der Monsuneffekt ist die wichtigsto von den ursachlichen Faktoren, die hauptsachlich uber die Japanische Vegetationsverteilung entscheidend verfugen. Das merkwurdigste Exemplar von diesen Beeinfluβungen ist die alpine Vegetationsverteilung im Winter. Der Monsun, der das Japanische Meer uberschreitet, bringt nicht nur gewaltige Schneemasse, sondern auch mechanische Umgestaltung der stehenden Baume. Die Schneemasse bestimmt auf anderer Seite die vegetative Wachstumsperiode. Also kann man aus Formumwandlungen von den isoliert stehenden Tannenbaumen (Abies mariesii) im Zwergkieferngestrauche, das uber die alpine Waldgrenze dominert, im Vergleich mit jedem Relief die Kausalitat der Vegetationsverteilung zuruckfolgen. In der subalpinen Region des Hakusan Gebirges sind die Standorte von Abies mariesii verkleinert, dagegen kommen diejenigen von Betula ermani praponderant und weiter vor. Dieses wird ein schlagender Anhaltspunkt dafur, daβ der Monsuneffekt als eine ursachliche Faktor auf die Vegetationsverteilung einwirkt. In der alpinen Region des Hakusan Gebirges sind die Areale von Moorgesellschaften im hochsten Grad verkleinert, dagegen verbreiten sich die Hochstaudenwiesen sehr weit. Dieses wurde bedeuten, daβ im tatigen Vulkan Hakusan Mineralsalze, welche die vulkanischen Auswurfe enthalten, jedem Relief und jeder Schmelzwassersmenge nach im verschiedenen Grad dem Pflanzenreich geliefert sind.

The relationship of the food habits to the habitat of nigorobuna larvae was investigated at Yamanoshita. Bay in the south basin of Lake Biwa from 1964 to 1968. Quantitative analyses of feeding of the larvae were for consideration on the significance of the aquatic plant belt as the habitat of the larvae. Though the larvae are more or less distributed throughout the aquatic plant belt, they are very abundant in the submerged plant belt. The more abundant floating plant materials present, the higher the density of the larvae is observed. It is commonly observed that there is a fairly good quantity of plankters available for the nigorobuna larvae in the aquatic plant belt, and their amount increases corresponding to that of the floating plant materials. The nigorobuna larvae devoured small Crustacea and chironomid larvae which are commonly found in the aquatic plant belts, above all they eat Chydorus intensively. The bulk of the gut contents of the larvae increase in accordance with the increase of the amount of the plankters. The food habits of the nigorobuna larvae is discussed in relation to their habitat preference. It is suggested that a submerged plant belt with abundant floating plant materials where numerous small cladocerans flourish, is the most favourable as a nursery ground for the nigorobuna larvae.
