This paper reports the first record of Rugulopteryx okamurae in Calpe, Spain, suggesting recent colonization or undetected local spread, with implications for coastal management.

The paper develops a dynamic population model for the jellyfish Carybdea marsupialis by integrating biological complexity from a matrix model, showing sensitivity to polyp strobilation rate and pattern.

This paper models the invasion and management of Egeria densa, finding that preventive strategies are most cost-effective before the plant spreads.
