REU participant, Lily Tanner, asks questions about urbanization and riparian spiders

Urbanization often compromises the diversity and abundance of native species living in watersheds, and research has shown that riparian spiders are susceptible to land use change associated with urbanization. As part of her REU, Lily conducted a spider density survey in riparian habitats in and around Atlanta as a metric to assess the impact of urbanization on regional spider populations. Her results indicated that overhanging vegetation was related to higher densities of web-weaving species. Increasing amounts of overhanging vegetation was also related to increasing bank slope, suggesting there may be potentially important interactions between physical and biological characteristics of riparian areas that mediate spider population structure.
