A study demonstrates the damage caused by ingesting invasive algae to the common sea urchin.

Echinoids from areas with longer exposure to Rugulopteryx okamurae are more vulnerable One study places the most invasive age of algae in summer and autumn

Promoting the availability of native algae in invaded areas "could help mitigate the impact of exotic algae on native species," explain Ifapa scientists. A study identifies the most invasive season for the algae 'Rugulopterix okamurae'.

The results of an Ifapa experiment, published in Marine Pollution Bulletin magazine, have shown that hedgehog populations from areas with a longer invasion period are more vulnerable to invasive algae.During this experiment, which has lasted 24 weeks, sea urchins from places with a different invasion history have been fed with two diets, a strict diet of 100% algae and a mixed diet of 50% seaweed and sea lettuce. Thus, the response of sea urchin…
