Repeated hyposalinity pulses immediately and persistently impair the sea urchin adhesive system

Test diameter, locomotor performance, tube foot disc area, tube foot disc tenacity, and tube foot tensile behavior of green sea urchins (Strongylocentrotus droebachiensis) repeatedly exposed to three different salinity treatments (control = 32 ppt; moderate hyposalinity = 22 ppt; severe hyposalinity = 16 ppt). Data are accompanied by R code used for data analysis.
