Populations from the species' native range (Mozambique) are compared to a population from New Caledonia (Wester Pacific), an island where the species was introduced in 1954. The results support the complete local extinction of the gill parasite community in the course of the invasion process. Up to six gill parasite species per locality were documented in the O. mossambicus native range, and previous surveys consistently reported at least one parasite species introduced along African cichlid species established out of Africa. The absence of parasites in New Caledonia is therefore exceptional. This can be attributed to local factors, such as a strong initial population bottleneck, the likely absence of multiple host introductions, and the frequent occurrence of brackish watersheds that might enhance the probability for natural deparasitation. specialized Ancyrocephalidae Biological invasion Enemy release Monogenea Tilapia MOZAMBIQUE NOUVELLE CALEDONIE 034 115 9 3657-3661 2016 0932-0113 https://www.documentation.ird.fr/hor/fdi:010068138 10.1007/s00436-016-5168-1 0932-0113 [F B010068138] https://www.documentation.ird.fr/hor/fdi:010068138 https://www.documentation.ird.fr/intranet/publi/2016/10/010068138.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-11-03 2017-08-23 fdi:010068138 fre
