SAU-WAI YAMHuang K.-P.Hsieh H.-L.Lin H.-J.Huang S.-C.2020-01-142020-01-1420151661-7827https://scholars.lib.ntu.edu.tw/handle/123456789/449053Natural wetlands have been increasingly transformed into urbanized ecosystems commonly colonized by stress-tolerant non-native species. Although non-native species present numerous threats to natural ecosystems, some could provide important benefits to urbanized ecosystems. This study investigated the extent of colonization by non-native fish and bird species of three urbanized wetlands in subtropical Taiwan. Using literature data the role of each non-native species in the urbanized wetland was evaluated by their effect (benefits/damages) on ecosystem services (ES) based on their ecological traits. Our sites were seriously colonized by non-native fishes (39%–100%), but <3% by non-native birds. Although most non-native species could damage ES regulation (disease control and wastewater purification), some could be beneficial to the urbanized wetland ES. Our results indicated the importance of non-native fishes in supporting ES by serving as food source to fish-eating waterbirds (native, and migratory species) due to their high abundance, particularly for Oreochromis spp. However, all non-native birds are regarded as “harmful” species causing important ecosystem disservices, and thus eradication of these bird-invaders from urban wetlands would be needed. This simple framework for role evaluation of non-native species represents a holistic and transferable approach to facilitate decision making on management priority of non-native species in urbanized wetlands. © 2015 by the authors; licensee MDPI, Basel, Switzerland.Alien species; Asian wetlands; Ecosystem services; Exotic species; Management; Urban ecosystems[SDGs]SDG3[SDGs]SDG6[SDGs]SDG11[SDGs]SDG15abundance; bird; colonization; ecosystem service; holistic approach; introduced species; migratory species; native species; urban ecosystem; wetland; aggressiveness; animal behavior; animal dispersal; Article; biodiversity; bird; competitive behavior; environmental impact assessment; fish; introduced species; migratory species; nonhuman; Oreochromis; population abundance; population research; sediment; species richness; Taiwan; urbanization; waste water; wetland; animal; biodiversity; environmental protection; physiology; procedures; urbanization; Taiwan; Aves; Oreochromis; Pisces; Animals; Biodiversity; Birds; Conservation of Natural Resources; Fishes; Taiwan; Urbanization; Wetlandsjournal article10.3390/ijerph1204039262-s2.0-84927558634https://www2.scopus.com/inward/record.uri?eid=2-s2.0-84927558634&doi=10.3390%2fijerph120403926&partnerID=40&md5=5b07665bec445f31ca78072ae250698f
