Across the time series Lithobates clamitans is the most frequently occurring speciesMethods
We estimated larval densities of 14 species of amphibians in 37 ponds on the University of Michigans E. S. George Reserve (hereafter ESGR) over 15 yrs (1996 to 2010). The ESGR is a 525 ha tract located 40 km northwest of Ann Arbor, Michigan. Sampling was conducted the third week in May and the third week in July to estimate densities of spring and summer breeding species. Samples were taken by pipe sampling, dipnetting and seining. The pipe sampler was constructed of a 76-cm length of 36-cm diameter aluminum pipe that sampled 0.1 m2 of water column and sediments. The sample was taken by quietly approaching an area and quickly thrusting the pipe through the water column and into the sediments to seal the sample area. Nets were then employed to remove all animals from the sampled water column and the first few centimeters of the sediments. Sampling effort varied with size of the pond typically ranging from 2040 pipe samples haphazardly distributed across micro- habitats in the ponds.Citation(s)
