Percentage of Primnoella chilensis polyps activity states under sediment exposure of 15 days, observation period 21 h, Control, Punta Gruesa ...
To determine behavioural stress, polyp activity states of Primnoella chilensis colonies were observed for 21 hours after eleven days under turbid seawater exposure in an experimental setup (Treatment: equals sedimentation rate of 450 mm/y; control group: ambient seawater). Image analysis was conduct...
