Saguinus fuscicollis weddelli and S. labiatus labiatus made intraspecifically territoriastic groups consisting of 2 to 7 individuals and often made interspecifically associated groups. They moved in associated groups in the day time. However, there were differences in height preference for moving and in the size of the insects consumed by the 2 species. The animals also had their own parturition seasons and sleeping sites. S. labiatus is larger than S. fuscicollis in body size, and the intermembral index showed a larger value for S.fuscicollis than for S. labiatus

Does low urban density increase municipal expenditure? Population density as a performance target for compact city planning in Japan

In depopulating cities, vacant houses and lots are common throughout the urban area, creating low-density urban areas that can lead to inefficiencies in public services and financial deterioration for municipalities. However, despite some studies demonstrating the relationship between population density and public expenditure, no generalized conclusion regarding the essential effect of reducing public expenditure has been reached. Consequently, no method for rationally setting a population density as a performance target for municipalities when developing compact city planning has been established. Thus, this study used the cross-sectional data from Japanese municipalities and the exponentiation regression equation, to determine the strong relationship between population density and per-person public expenditure (PPPE). The findings are particularly noteworthy for municipalities that grew under a nationwide uniform city planning and accounting system, as they provide valuable insights into the generalization of the public expenditure reduction effect. Furthermore, this study developed a method using the exponentiation regression equation, which demonstrated an L-shaped trajectory indicating that PPPE increases at an accelerating rate when population density falls below a certain threshold. Municipalities can evaluate the efficiency of public expenditure simply by applying their population density to the regression equation. They can also verify population density as a performance target. Furthermore, this study revealed the turning point of population density at which the acceleration in the increase in PPPE begins, implying that municipalities can expect a grace period until the turning point

Sustainable Downtown Development for the Tsunami-Prepared Urban Revitalization of Regional Coastal Cities

Regional cities in Japan are facing a decline in the downtown area owing to urban expansion and a decrease in the population. Promoting downtown living is indispensable for the realization of downtown revitalization. Since many coastal cities originally developed outward from a port, their downtown areas are located near the coast and are at high risk of tsunamis. The purpose of this research is to reveal the effectiveness of dealing with the above two issues in parallel by evaluating the Deae-ru Saiwai estate, a public housing relocation project in downtown Kushiro, Hokkaido, Japan that incorporates a tsunami evacuation facility with questionnaires and a GIS survey. Placing public housing in the downtown area shortens the distance to public facilities and improves the convenience of the surrounding environment for many residents. Installing the tsunami evacuation facility improves the feeling of reassurance of residents who would feel anxiety about immigration with regards to tsunamis. This research has clarified the synergistic effect of dealing with the daily and emergency issues in parallel for promoting downtown living. Planning downtown revitalization and disaster prevention concurrently, which has been separated so far, is a fundamental planning approach for urban revitalization in regional coastal cities
