Phylogeography of Sula: the role of physical barriers to gene flowin the diversification of tropical seabirds

Brown Booby (Sula leucogaster) Science Article 11 abstract We examined mitochondrial cytochrome b sequence variation in masked Sula dactylatra,red-footed S. sula, and brown S. leucogaster boobies sampled from islands inthe central and eastern Pacific Ocean and in the Caribbean Sea. Each species showeda different phylogeographic pattern. Whereas haplotypes in masked and red-footedboobies were shared across […]

Dna fingerprinting and parentage in masked (sula dactylatra) and brown (s. leucogaster) boobies

Brown Booby (Sula leucogaster) Science Article 10 abstract Masked Booby (Sula dactylatra) and Brown Booby (S. leucogaster) are pantropical seabirds. These species are socially monogamous. Thus, males and females have a high investment in parental care. In this work, field observations and DNA fingerprinting were applied to investigate the breeding system of both species. Two […]

Molecular Phylogeny of Babesia poelea From Brown Boobies (Sula leucogaster) FromJohnston Atoll, Central Pacific

Brown Booby (Sula leucogaster) Science Article 2 abstract The phylogenetic relationship of avian Babesia with other piroplasms remains unclear, mainly because of a lack of objective criteria such as molecular phylogenetics. In this study, our objective was to sequence the entire 18S, ITS-1, 5.8S, and ITS-2 regions of the rRNA gene and partial B-tubulin gene […]

Occurrence of Contracaecum pelagicum Johnston & Mawson 1942 (Nematoda,Anisakidae) in Sula leucogaster Boddaert 1783 (Pelecaniformes, Sulidae)

Brown Booby (Sula leucogaster) Science Article 7 abstract Brazilian wildlife birds constitute a group in which the parasite-host relationship still needs to be investigated. Several studies about the identification of new parasites or about the description of new hosts have been published. The present study describes the occurrence of Contracaecum pelagicum Johnston & Mawson 1942 […]

Obstruction and starvation associated with plastic ingestion in a Northern Gannet Morus bassanus and a Greater Shearwater Puffinus gravis

Northern Gannet (Morus bassanus) Science Article 1 abstract Plastic ingestion by seabirds is well documented (see Laist 1997for a list of species with ingestion records). However, casesdefinitively attributing seabird mortality to ingestion of plastic arerare. Seabirds that die from ingestion often suffer obstruction of thegastrointestinal tract. Ultimately, the birds die of starvation andoften quickly sink […]

POSSIBLE HYBRIDIZATION BETWEEN THE PERUVIAN BOOBYSULA VARIEGATA AND THE BLUE-FOOTED BOOBY S. NEBOUXIIIN LOBOS DE AFUERA ISLANDS, PERU

Masked Booby (Sula dactylatra) Science Article 3 abstract Many hypotheses have been formulated to explain the causes of the relatively uncommon phenomenon of siblicidal aggression. All have been supported by evidence, however, no single hypothesis can fully explain the cause of avian siblicidal aggression Melissa Schramm ET AL., Avian Siblicidal Aggression Download article download full […]

EFFECTS OF THE 1982-83 EL NINO EVENT ON BLUE-FOOTED AND MASKED BOOBY POPULATIONS ON ISLA DAPHNE MAJOR, GALAPAGOS

Masked Booby (Sula dactylatra) Science Article 6 abstract El Nino events have negative effects on seabird populations in the equatorial Pacific, including the Galapagos Islands, by causing reductions in food supplies.

First South Carolina Specimens of theMasked Booby (Sula dactylatra)

Masked Booby (Sula dactylatra) Science Article 1 abstract The Masked Booby (Sula dactylatra) is a pelagic warm-water species rarely seen near shore (Clapp et al. 1982). On the North American Atlantic coast, seabirds such as boobies are most often found in productive feeding areas far from land. William Post, The Chat, Vol. 68, No. 1 […]

Breeding biology of Masked Boobies (Sula dactylatra tasmani) on Lord Howe Island, Australia

Masked Booby (Sula dactylatra) Science Article 2 abstract The breeding biology and reproductive output of a colony of Masked Boobies on Mutton Bird Point, Lord Howe Island, Australia, were studied during the 2001 02 breeding season. The colony produced a total of 200 clutches. Eggs were laid between 31 May and 15 September 2001, with […]
