Ant fauna was resurveyed at campus of Ikarashi in Niigata University.Collections were carried out every week from April to November in 2014 at eight sites of the campus, using three different collection methods (hand collection, pitfall traps and honey bait traps). A total of 18 species belonging to four subfamilies (Formicinae, Dolichoderinae, Myrmicinae and Ponerinae) and 15 genera were collected. The eight sites were divided into three groups by the similarity of the ant species composition. Division into the three groups may be due to vegetation, food preferences of ants and soil characteristics. Ants are among the most suitable groups of animals for community characterization, since they are diverse, very abundant and occur virtually in all ecosystems. Our results showed a further evidence that ants are reliable ecological indicators for evaluating environmental conditions. We propose that monitoring ant fauna is a good tool to apply environmental education.

Water-silicone oil emulsion with a silane coupling agent was used as a phase change material. Using stainless steel vessels coated with PFA resin, experiments of forming ice with stirring were carried out under various conditions of the temperature of brine for cooling and the composition of emulsion. We investigated the correlation between cooling heat flux and ice adhesion to the cooling surface in the ice formation process. The following results were obtained, (a) Silicone oil has the effect of preventing the formed ice from adhering to the cooling surface, (b) Under a condition of the same concentration of the additive, the maximum cooling heat flux without adhesion in the case of water fraction of 80vol.% was larger than that in the case of 100%.
