Alien invasive species are introduced with or without intent and spreading all over Korea. They are known to have negative effects on biodiversity such as economic and environmental damage and causing decrease or loss of native species. The habitats like wetland, reservoir and riverside are especially in danger of being invaded by alien species due to stress and disturbance. Therefore, Korea National Arboretum is steadily working on research and studies on managing alien invasive species. This research aims to collect basic information of Ludwigia peploides subsp. montevidensis (Spreng.) P.H. Raven which was found near riverside in Suwon-si and is concerned to become an invasive alien species. We expect the description, diagram and pictures of this taxon will be helpful for early detection and effective management.

Carbonic anhydrases catalyze the hydration of carbon dioxide and are essential for regulation of cellular pH and carbon dioxide transport. CA is the zinc metalloenzyme that catalyses the reversible reactions of CO2 with water. To date, 16 isozymes belonging to the α-CA gene family. A carbonic anhydrase isozyme is present in shaggy sea raven, Hemitripterus villosus. Carbonic anhydrase isozyme protein isolated from several tissues showed specific protein band with molecular weight of 30 kDa. The isolated protein band was identified as a carbonic anhydrase isozyme.
