Role of sea urchins on California kelp

Source: Science Daily

California sheephead and spiny lobsters may be helping control sea urchin populations in Southern California kelp forests, where sea otters — a top urchin predator — have long been missing, according to a new study. The research provides new insight into the complex predator-prey relationships in kelp forests that can be seen in the absence of sea otters.
