Cоntrоlled field experiments with а vаriety оf species were used to test the effects of surfаce-deposit feeders on succession. Tube building organisms included Hobsonia florida and Oligochaeta species. An amphipod (Corophium salmonis) was tested as well. In the 'Control' treatment, the species indicated on the y-axis on each graph was grown alone versus when grown in the presence of the other species indicated in the legend. While there is no statistical information in the figure, the paper states that for the first experiment (effect of the presence of H. florida on oligochaetes), the results were not significantly different. For the second experiment (effect of H. florida on C. salmonis), the results were statistically significantly different. 1. The effect of H. florida on Oligochaete sp. was [success1]. 2. The effect of H. florida on C. salmonis was [success2]. Reference: Gallagher, E. D., Jumars, P. A., & Trueblood, D. D. (1983). Facilitation of soft‐bottom benthic succession by tube builders.
