A preliminary study of the ecology of a mud-flat

Abstract

Ten stations, from high water to low water, were investigated along a mud-flat in the Bristol Channel. The mud was analysed for water content and grade. The values suggested, with other observations, that the stations were distributed over two different areas. Quantitative analysis of both macrofauna and microfauna revealed a dense mud population. The operative ecological factors, including the food cycle, are defined.
