Abstract

This study evaluated sampling methods that provided better estimates of abundance and species richness of Collembola on a cobble-dominated riverbank. We compared samples collected 1 m from the river edge using coring, pitfall trapping (4-day duration), inert substrate trapping (4 days), and bait trapping (4 days) methods along the Sakawagawa River, Japan. In total, seven species of Collembola were collected. Isotomurus cf. qinpuensis, Isotomurus sp. 1, and Sminthurides potamobius predominated in most samples collected by coring and pitfall trapping. Pitfall trapping provided the greatest number of individuals and species per sample, followed by coring, although the differences between these two methods were insignificant. We suggest that the pitfall trapping method is likely the most efficient for sampling Collembola in cobble-dominated riverbanks for ecological assessments.
