Distribution and Sediment Selection by the Mud Shrimp <i>Upogebia noronhensis</i> (Crustacea: Thalassinidea) and the Potential Effects on the Associated Macroinfaunal Community
Burrowers such as thalassinideans remobilize sediment in benthic ecosystems, altering granulometry, enhancing organic matter cycling and oxygenation. We characterized the distribution of the mud shrimp <i>Upogebia noronhensis</i> and the associated macroinfauna along a depth and granulom...

Burrowers such as thalassinideans remobilize sediment in benthic ecosystems, altering granulometry, enhancing organic matter cycling and oxygenation. We characterized the distribution of the mud shrimp <i>Upogebia noronhensis</i> and the associated macroinfauna along a depth and granulometric gradient in a shallow subtidal area in the southern Brazilian coast. Mud shrimp densities were estimated by burrow opening count using 0.25 m<sup>2</sup> quadrats in three sediment zones: sand, sand-mud transition and mud.
