Effects of conspecifics on settling juveniles of the invasive golden mussel, Limnoperna fortunei

We conducted a field experiment to assess the influence of conspecific adults on recruitment success of the golden mussel Limnoperna fortunei. Tiles, 225 cm2 surface area, were used as artificial substrates in four treatments: control (blank tiles), low (800 mussels m-2), medium (4,000 mussels m-2)...
