Vertical distribution of maturity stages of Oikopleura dioica (tunicata, appendicularia) in the frontal system off Valdes Peninsula, Argentina
A differential pattern of vertical distribution of maturity stages of Oikopleura dioica was detected in the coastal thermal frontal system off Valdés Peninsula (Argentina). The highest densities of all maturity stages as well as the highest chlorophyll a concentrations were recorded in surface water...
