Title:	WEB SPIDER DIVERSITY IN RIPARIAN FORESTS OF SOUTHWEST OHIO
Author:	Higgins, Terrence Sean
Description:	Riparian forests are often the primary source of forest habitat in agricultural landscapes. I assessed the diversity of web spiders in riparian forests and hedgerows of SW Ohio. Samples were taken at the stream edge, in the center, and at the agricultural edge of riparian forests of three width classes (thin: 15-30m, medium: 45-60m, wide: >80m). Rarefaction and ANOVA compared diversity among forest types, and among the agriculture edge, center and stream edge. Detrended Correspondence Analysis compared the species assemblages among samples. Web spiders were significantly more diverse in riparian forests than in hedgerows. Thin riparian forests were most diverse of all forest types. While stream edges had the lowest diversity, their assemblages were distinct from other quadrats. My data suggest that the stream habitat plays a key role in structuring the adjacent terrestrial spider community, and that riparian forest corridors are important to regional spider diversity in agricultural landscapes.
