摘要：Species richness and diversity are two key concepts often used in assessing ecological integrity. Intensive agricultural practices generally create homogeneous landscapes and severely reduce biodiversity. The goal of this study was to examine the effect of fragments of the forested riparian ecosystems on terrestrial invertebrate diversity and richness located along ditches within Wood County Ohio. We hypothesized that invertebrate diversity will be significantly correlated to the quantity and quality of the riparian systems. We also hypothesized that the diversity and richness of terrestrial invertebrates will be higher along segments of ditches that had riparian zones, compared to segments of ditches that did not have riparian zones. Forested and non-forested habitats located within the riparian zones of agricultural ditches were sampled using pitfall traps, made of two liter soda bottles. Five forested and five non-forested sites were sampled with three pitfall traps placed evenly within each riparian zone site. The traps were open for one week from early July to early October 2002. The traps were collected once a week for analysis and identification of the insects with field guides and identification books. Diversity was calculated using the Shannon diversity index. Data from the forested sites were compared to those from the non-forested sites using analysis of variance. Invertebrate diversity in the forested riparian sites was plotted against riparian zone area. Examining the species richness and biodiversity of riparian zones located along ditches in agricultural landscapes allowed us to determine the potential for diversity in such stressed ecological environments.

Species richness and diversity are two key concepts often used in assessing ecological integrity. Intensive agricultural practices generally create homogeneous landscapes and severely reduce biodiversity.
