Plumage polymorphism of red-footed boobies (Sula sula) in the western Indian Ocean: an indicator of biogeographic isolation
The pantropical red-footed booby Sula sula is one of the most polymorphic seabirds. In the Indian Ocean most extant colonies hold white morph adults except on Europa Island (southern Mozambique Channel), where adults are of the white-tailed brown morph and on Tromelin Island (western Indian Ocean), where one-third of the birds are of the white-tailed brown morph and two-thirds are of the white ...
متن کاملThe genetic basis of the plumage polymorphism in red-footed boobies (Sula sula): a melanocortin-1 receptor (MC1R) analysis.
The red-footed booby (Sula sula) is considered one of the most polymorphic seabirds, with 3 recognized major adult plumage types: 1) white, 2) white-tailed brown, and 3) brown and several degrees of intermediates. Here we show that the white/melanic polymorphism observed in this species is perfectly associated with 2 point substitutions, Val85Met and His207Arg, at the melanocortin-1 receptor (M...
متن کاملSome Acanthocephala and Digenea of Marine Fish from Grand Cayman, Cayman Islands, British West Indies
A survey of 17 fishes belonging to 11 species from Grand Cayman, Cayman Islands, West Indies, led to the recovery of 2 species of acanthocephalans and 9 of digeneans. The acanthocephalans found were Acanthogyrus (Acanthosentis) acanthuri and Dollfusentis ctenorhynchus. The digeneans included Monorchimacradena acanthuri in Acanthurus bahianus (new host record), Bucephalus varicus, Hurleytrematoi...
متن کاملHybridization from Possible Sexual Mis-imprinting: Molecular Characterization of Hybridization between Brown Sula Leucogaster and Blue-footed Boobies S. Nebouxii
Approximately 9.2% of avian taxa are known to hybridize, a larger proportion than most vertebrate groups. However, rates of hybridization vary widely across avian orders: ducks and geese (Anseriformes) hybridize widely and frequently, while hybridization between swift species (Apodiformes) has never been recorded (Grant & Grant 1992). Seabirds, excluding the whiteheaded gull complex (Charadriif...
متن کاملEradication of Aedes aegypti on Cayman Brac and Little Cayman, West Indies, with Abate (Temephos) in 1970-1971.
In 1948 Giglioli reported an abundance of Aedes aegypt; on Grand Cayman, the largest of the three Cayman Islands, and recommended control by intradomiciliary residual treatment with DDT (I). These recommendations led to implementation of a yearly cycle of DDT spraying between 1950 and 1954, supplemented by use of larvivorous fish (Gambusia puncticulata) and kerosene oil in cisterns and water co...
