| Research Abstract |
Recently, Satoyama, the traditional rural landscape of Japan, has been paid much attention, because, beside many important roles, it is a key to biodiversity conservation in Japan. Effects of restoration of paddy fields, which had been abandoned for 30 years, on the biodiversity of arthropods associated with the rice plants in the paddies. The paddies were restored gradually year by year, and the change of the biodiversity was monitored from 2004 to 2007. A total of 4993 individuals (17 orders) and 2508 (13 orders), 2171 (12 orders) were collected from the paddies in 2004, 2005 and 2006, respectively. Proportion of the predators such as spiders in the samples increased clearly during the study.
Habitat heterogeneity and restoration activities on abundance and diversity of ground arthropods and above-ground arthropod assemblages were studied using pitfall traps and window traps, respectively, in the "satoyama area" within Kanazawa University's Kakuma Campus, Kanazawa, Japan from 2004 and 2006. Monthly samples were taken from nine sites, including forested areas and valley areas with paddies under restoration. For the samples obtained by the two sampling methods, an order level analysis with DCA ordination revealed a clear separation of arthropod order compositions among different habitat types and the changes in the faunal composition over the restoration of the paddies were confirmed.
