Land use and anuran biodiversity in southeast Kansas, USA
- The relationship of anuran breeding site biodiversity to land use was examined in southeast Kansas, USA. Eight breeding pools or temporary ponds were sampled from March to July 1995. Each site has some adjacent woodland, but varied in the remaining adjacent land use. Two sites were relatively unimpacted reference or “natural” sites, two were impacted by abandoned coal or lead/zinc mines, and four were impacted by cropland. Adult density was determined with visual and audio censuses. Tadpoles were examined for malformations and density was estimated. Eggs were collected from the sites, hatched in the laboratory, and examined for malformations. Total audio anuran density was statistically higher (ANOVA, P<0.05) in natural area breeding pools (1,048.7/ha) compared to pools in agricultural (519.0/ha) and mined areas (164.8/ha). Visual densities followed the same pattern (459.9/ha natural > 315.1/ha agricultural > 262.0/ha mined) but were not statistically different. Tadpole densities were significantly (P<0.05) higher in natural area breeding pools (137.6/m2) compared to agricultural (59.4/m2) and mined areas (28.5/m2). The percentage of tadpoles with malformations was significantly lower (P<0.05) in natural areas (0.4%) compared to agricultural (4.6%) and mining (8.3%). Malformations found in the field included spinal cord, optic, edemas, and tumors. Eggs incubated from natural sites had significantly (P<0.05) higher percentages of eggs hatching successfully (98.8%) and lower percentages of tadpoles with malformations (17.5%) than did eggs from agricultural (88.2% and 51.0%, respectively) and mined areas (40.4% and 76.1%, respectively). Eggs incubated from natural sites also had the lowest malformation rate (17.5%) compared to eggs from agricultural sites (51.0%) and mined sites (76.1%), but these differences were not statistically different. These data provide evidence for the link between land use and the individual and population characteristics of anurans in breeding pools.
