Estimating the abundance of benthic macrofauna from across shore transects
Abstract
Benthic macrofauna of the intertidal zone are commonly sampled at low tide by excavating and sieving quadrats or cores on across shore transects. This paper examines different equations for estimating transect scale abundance, introduces the sampling theorem for calculating the maximum sampling interval and uses simulations to investigate sampling issues. Adaptive transect designs are recommended, where the sampling interval and replication of quadrats are carefully selected according to the width and density of macrofauna bands.
