ItemThe Diets of Sula dactylatra, Sula sula, and Fregata minor on Christmas Island, Pacific Ocean(University of Hawaii Press, 1976-07)The diets of the Blue-faced Booby (Sula dactylatra), the Red-footed Booby (Sula sula), and the Great Frigatebird (Fregata minor) were studied by analyses of reg urgitation samples. Flying fish and squid composed the majority of the diets, but the Frigatebirds also consumed numerous Sooty Tern (Sterna fuscata) pulli. These data allow comparison with similar earlier studies of the smaller bird species that inhabit the atoll and indicate that resource partitioning occurs through the percentage of fish and squid taken and the size of the prey items taken, with the larger species of birds eating larger fish and squid.

ItemEarly Life History of the Giant Clams Tridacna crocea Lamarck, Tridacna maxima (Roding), and Hippopus hippopus (Linnaeus)(University of Hawaii Press, 1976-07)Giant clams may be stimulated to spawn by the addition of macerated gonads to the water. Individuals of Tridacna maxima collected at Anae Island, Guam, spawned from November to March. On Palau, Hippopus hippopus spawned in June and Tridacna crocea, in July. Tridacna crocea, T. maxima, and H. hippopus displayed a stereotyped development pattern in morphogenesis and rate of development. Fertilized eggs of T. crocea, T . maxima, and H. hippopus had mean diameters of 93.1, 104.5, and 130.0 um, respectively. The day-2 straight-hinge veligers of T. crocea, T. maxima, and H. hippopus had mean shell lengths of 155.0, 168.0, and 174.4 pm, respectively. Settlement occurred 12, 11, and 9 days after fertilization at a mean shell length of 168.0, 195.0, and 202.0 pm for T. crocea, T. maxima, and H. hippopus, respectively. Metamorphosis was basically complete about 1 day after settlement. Juveniles of T. crocea, T. maxima, and H. hippopus first acquire zooxanthellae after 19, 21, and 25 days, respectively. Growth rates increase sharply after the acquisition of zoo xanthellae. Juvenile shells show first signs of becoming opaque after 47 days for T. maxima and after 50 days for H. hippopus.
