Brief description

An experiment was conducted to compare the effects of the introduced bryozoan, Bugula neritina, and the native bryozoan, Bugula dentata, on sessile invertebrate assemblages. Individuals of both species were collected from Workshops Jetty and Altona Pier prior to the experiment and transported back to the laboratory. Two colonies of either B. neritina or B. dentata were attached to each plate using sponges that expanded when wet. The plates were then transported to Workshops Jetty and attached to plates and left for 12 days. At the conclusion of the experiment plates were collected and abundances of species on the plates were counted and identified.

Maintenance and Update Frequency: notPlanned
Statement: Experimental design Bugula colonies were added to plates by wrapping the base of each colony in a foam sponge and then pushing them firmly into 5mm holes in the plate. When placed in water, the sponge expanded and secured the Bugula in place. A procedural control was included in the experiment design and was a foam sponge with no Bugula added. There were a total of 12 plates (4 replicates of each treatment and control) randomly arranged on 2 backing panels and suspended from the pier in Williamstown, Victoria.
