A survey of 11 locations in the easternmost region of the Tierra del Fuego archipelago revealed no significant differences in the abundance of giant kelp (Macrocystis pyrifera) or the sizes of the kelp holdfasts (the part that anchors it to the rocky bottom) since they were first surveyed more than 45 years ago. According to a study published in the journal PLOS ONE, the diversity and amounts of sea urchins also remained relatively unchanged between the two time periods.
