Abstract | Wetlands dominated by Prairie Cordgrass, Spartina pectina (Poaceae), burned annually or at 10- to 20-y intervals were investigated in 1993 and 1994 to quantify the effects of fire on spider community structure and population density. Burned and unburned wetlands had similar spider species; however, annually burned wetlands had both greater species richness and higher spider densities than long-term unburned wetlands. These dynamics parallel differences in insect densities in these wetlands. Previous work has shown that annually burned S. pectinata has much higher annual productivity; thus, the greater number and density of spiders in annually burned wetlands are consistent with these increased energy inputs. |
