Invasive alien species (IASs) on islands have broad impacts across biodiversity, agriculture, economy, health and culture, which tend to be stronger than on continents. Across small-island developing states (SIDSs), although only a small number of IASs are widely distributed, many more, including those with greatest impact, are found on only a small number of islands. Patterns of island invasion are not consistent across SIDS geographic regions, with differences attributable to correlated patterns in island biogeography and human development. We identify 15 of the most globally prevalent IASs on islands. IAS impacts on islands are exacerbated through interactions with a number of other global change threats, including over-exploitation, agricultural intensification, urban development and climate change. Biosecurity is critical in preventing IAS invasion of islands. Eradication of IASs on islands is possible at early stages of invasion, but otherwise is largely restricted to invasive mammals, or otherwise control is the only option. Future directions in IAS management and research on islands must consider IASs within a broader portfolio of threats to species, ecosystems and people’s livelihoods on islands. We advocate for stronger collaborations among island countries and territories faced with the same IASs in similar socio-ecological environments.

The shorefishes of Ouvea, an isolated atoll in the Loyalty Islands group of New Caledonia, had not been surveyed prior to 1990. An extensive survey was conducted by ORSTOM between 1991 and 1992 to obtain baseline information on the shorefishes. A total of 653 taxa among 72 families are now documented from this area. The most diverse families are the Labridae (69 species), Pomacentridae (58 species), Gobiidae (54 spccies),Serranidae (39 species), Chaetodontidae (31 species) and Apogonidae (28 species). The absence or very low diversity of some families (Clupeidae, Nemipteridae, Siganidae) or genera (Abudefduf, Neopomacentrus) is similar to findings for other isolated islands of the Coral Sea. Of the 653 species recorded from Ouvea, 51 species have not been reported from New Caledonia, a large high island to the South. Only one endemic species, Luzonichthys williamsi, has been recognized among the shorefishes at Ouvea. A number of Pacific Plate endemic species were recorded at Ouvea. which is positioned on the Australasian Plate to the south of the edge of the Pacific Plate. Antennarius duescus, previously known from three specimens taken at the Hawaiian Islands, is recorded from a single specimen taken at Ouvea. Another antitropical distribution pattern is exhibited by Dinemalichthys riukiuensis, which is known to occur at Fiji, Ouvea and Queensland in the South and from Okinawa.
