Spatial And Temporal Patterns Of Abundance And Recruitment Of Ghost Shrimp Trypaea Australiensis Across Hierarchical Scales In South-Eastern Australia, Douglas Rotherham, R. J. West

Faculty of Science - Papers (Archive)

Spatial and temporal variation in abundance and recruitment of burrowing ghost shrimp Trypaea australiensis was examined across 3 south-eastern Australian estuaries using a hierarchical sampling design, over a 2 yr period. We tested the hypothesis that abundances of shrimp were different between plots (10s to 100s of metres apart), sites within estuaries (kilometres apart), estuaries (100s of kilometres apart) and through time. More frequent sampling at 1 site also examined temporal variation at scales of months, seasons and years. Another aim was to investigate the reliability of using counts of burrow openings to indirectly measure the relative abundance of T, …
