At Ouvea, the lack of suitable habitat is not a likely reason for the low number of these species, except possibly for the Clupeidae. Indeed, the habitats where these species are found in New Caledonia are apparently present at Ouvea (Kulbicki et al., 1993a). The early life history traits (type of egg, length of larval life, shape of the larvae, size of the larvae at recruitment on reefs) of Abudefduf and Neopomacentrus (Table 3) do not differ significantly from those of other Pomacentridae that are present at Ouvea, Rotuma, the Chesterfield Islands, or Osprey Reef. Victor (1991), in a review on settlement strategies and biogeography, noted that duration of the larval stage rarely accounted for the geographic range of a species. The short distance between Ouvea and the main island of New Caledonia (60 km) and the direction of the major surface currents (Kulbicki et al., 1993a; Kulbicki, 1995) would not seem to present a major obstacle to the colonization of Ouvea by species from New Caledonia (figure 3). OCEAN PACIFIOUE. Fig. 3. Major currents in the vicinity of Ouvea (from Kulbicki et al., 1993a). One possible reason for the lack of certain species at Ouvea could be related to its being a low island and New Caledonia a high island. Causal factors leading to the absence of certain taxa at Ouvea remain Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Smithsonian Institution.
