The effect of chronological and spatial changes on populations and communities is a major challenge to biodiversity. Considering the rapid changes in habitats, the functional implication of habitat modification has to be quantified with high priority. Many large areas in Japan have been detected to suffer from enormous alterations and modifications in their structures. One of these areas is Zontan area in Ishikawa Prefecture, Japan. In this paper, we suggested that an essential perquisite for the prediction of population and communities is performed by establishing quantitative links between Tempo-spatial patterns and biodiversity of orthopteran species co-occurring in the Zontan area, Japan. In this investigation, orthopteran species were collected using sweep-net sampling procedures. Species richness, diversity, similarities, singletone and doubletone species were extensively examined. In this study, we tried to give an answers for the following questions: (1) does the decline or modification affect the species richness of Ortoptera?; (2) what group, or species, of Orthoptera is more sensitive?
