Changes in the abun- dance and the species richness were monitored at three heights in the forest throughout the season in 1999, using yellow and blue water pan traps. The results showed signifi- cant variations in the abundance of Mordellidae among the canopy layers, while little variation was found for Cerambycidae. The abundance, species diversity, and rich- ness were generally greater in summer. The results showed distinct species compositions in both families among layers. Key words Canopy beetles · Forest strata · Vertical distri- bution · Satoyama · Trap color Introduction Coppice woodland or satoyama in Japanese, covers ap- proximately 40% of the national landscape of Japan. Re- cently, this landscape has come under increasing pressure from the expansion of urban areas. There is evidence to show that certain types of destruction have had serious impact on the species richness of butterflies (Kitahara and Fujii 1994; Moriyama 1996). Recently, efforts toward conservation and management in this habitat have become concerted, and data of canopy insect compositions, including beetles, are one of basic in- puts into management plans. However, local-scale data of canopy insects at the species level is insufficient due to difficulty in gaining access into the canopies of suburban forests. This study presents a local-scale species composi- tion of two anthoxylic/saproxylic families, Mordellidae and Cerambycidae, because such literature information is, to date, insufficient (e.g., Shiyake 1993; Kirmse et al. 2003). The aim of this study was to investigate the abundance, species diversity, richness, and composition of these fami- lies in correlation with height, trap color, and season. Study site and methods This study was carried out on a research tower located in a 74-ha suburban coppice woodland of Kanazawa University, about 6 km southeast of Kanazawa city in central Japan (36°33¢N, 136°43¢E, 150 m in altitude). The tower was con- structed of alloy metal with a height of 23 m. The mean annual air temperature in Kanazawa is 14.3°C, with the highest monthly mean temperature of 26°C (August) and the lowest of 1°C (January) (Leksono et al. 2005). The vegetation around the tower is a secondary deciduous broad-leaved forest dominated by deciduous oak trees: Quercus serrata and Quercus variabilis. A subcanopy layer is composed of various saplings and shrubs including Cornus spp., Ilex spp., and Styrax spp.; while an understory layer is composed of Callicarpa spp., Eurya spp., Lindera spp., and Vibrunum spp. (Nakamura et al. unpublished data). The upper canopy usually reaches a height of 20–24 m with diameter at breast height (DBH) of 20 cm or greater, while the heights of subcanopy and understorey plant spe- cies are below 10 m. This area was formerly developed from the preindustrial rural agricultural landscape. In the 1980s, a part of the area was converted into the university campus. In 1997, the re- maining area was declared as reserved area and has been used in many activities such as field studies by Kanazawa University, environmental education, and nature conserva- tion by local people. Recently, management of the forest and restoration of terraced paddy fields have been initiated A.S. Leksono · N.
