    Studies on the submerged plant community in Lake Biwa. I. Distribution and productivity of Egeria densa. A submerged plant invader in the south basin [Translation from: Physiol.Ecol.Japan 17, 283-290, 1976] (2021)

    Description: Egeria densa (PLANCH.) ST. JOHN, a submerged plant invader, forms a wide submerged plant zone, particularly along the west coast of the south basin, Lake Biwa. The macrophyte occupies over 82% of the plant zone in the basin and its biomass reaches 93% of the total. The estimated annual net production was approximately 1 kg dry wt./m2 in a dense area, which is about 4.5 times as much as the net production by phytoplankton in an offshore area of the basin. Although the area covered by the macrophyte is only 5.8% of the total of the basin, it produced about one-tenth of the total annual primary production. In the most productive season Egeria produced 46% of the total primary productivity. Thus, the macrophyte never be neglected when one considers the energy flow or material circulation in the basin. This study was initiated in order to clarify the role of submerged macrophytes, particularly E. densa, in Lake Biwa. The following points are reported in this paper: the distribution of macrophytes in the south basin; seasonal change in standing crop of E. densa; seasonal change in values related to production, utilizing a model proposed by Ikushima with its parameters experimentally determined.

    Avoided temperatures by young fish [Translation from: Informatsionnyi Byulleten Biologiya Vnutrennikh Vod No.50, 45-47, 1981] (2021)

    Description: Directed local changes of water temperature for the purpose of controlling the behaviour of fish are based on the knowledge of the characteristics of seasonal-age dynamics of their thermoadaptation possibilities. These possibilities are still inadequately studied especially in relation to avoided temperatures. By the authors the attempt was made to determine zones of avoided temperatures for the young of five species of fish (bream, roach, blue bream, perch, peled) in the summer period of the year, and also to assess the influence on them of additional factors, in particular mechanical driving. In parallel in two-fold repetition were conducted experiments on the determination of selected, shock and lethal temperatures of these fish. Experiments were conducted with fish, caught in the littoral of the Rybinsk reservoir.

    Foraging organization of the open-air processional lichenfeeding termite Hospitalitermes (Isoptera, Termitidae) in Borneo (1998)

    Notes: Summary: The temporal dynamics and social interaction in the foraging activities of the open-air processional termite Hospitalitermes (Termitidae, Nasutitermitinae) were studied in Borneo, Southeast Asia. H. medioflavus and H. sp. A tended to forage from evening to the next morning. On average foraging activity occurred every 3.2 days. Some synchronization of foraging events among colonies was observed, which appeared to be caused by rainfall levels.¶ Temporal dynamics during foraging activity was observed in detail using a photographic method for two species; H. medioflavus and H. rufus. Roughly 300,000 to 500,000 individuals participated in a single foraging event in both species. The soldier ratio was highest at the beginning and the end of the activity. Temporal patterns of behavior were different between soldier, major worker, medium worker and minor worker during foraging. The patterns of behavior are consistent with their tasks in the foraging activity. Soldiers lead the foraging column and protect it, major workers act as food carriers in the earlier stage while medium workers become the dominant food ball carriers in the later stage, and minor workers play the role of gnawers. Therefore, caste composition changes during foraging activity. Similar behavioral tendencies were recognized in both species. Measurement of workers' body weights revealed that workers not only carry balls of food from foraging sites but also feed directly at the foraging sites.

    Diet and nest material of the processional termite Hospitalitermes, and cohabitation of Termes (Isoptera, Termitidae) on Borneo Island (1997)

    Notes: Summary: The processional termite Hospitalitermes is distributed over Southeast Asia and leaves the nest to forage in the open for lichens and other materials, primarily from tree trunks and canopies in rain forests. The diet of this genus, which is carried by workers in the form of food balls, has been thought to be valuable, because open-air foraging seems to have the risk of predation. We investigated the chemical composition (CHN ratio, amino acid composition and ash content) of food balls which the workers carry back from foraging sites to the nest. Nitrogen content of the food balls was 10 - 60 times as much as wood, which is the general food of the majority of termites, and suggests that the food balls are an important dietary source of nitrogen in this genus. At the study site a majority of Hospitalitermes nests are covered with the nest of a coexisting termite in the genus Termes. Since the nest materials of Termes contains much minerals, they are physically solid. They form the exterior shell of the Hospitalitermes nest (which is very fragile). In comparison with the nest materials of Hospitalitermes, Termes nests contain much less nitrogen. From this study, it is possible that some interactions between the two genera may exist especially in terms of nutrition.
