Pseudo-eggs of brown sula leucogaster andblue-footed s. nebouxii boobies in the gulf of california, mexico
Brown Booby (Sula leucogaster) Science Article 4 abstract Pseudo-eggs, foreign round objects, notably eggs of other speciesor pebbles, are common in some ground-nesting species, and havebeen reported especially in larids (Sugden 1947, Twomey 1948,Coulter 1980, Conover 1985). As many as 10% of Ring-billedGull Larus delawarensis nests in Washington, USA includedpseudo-eggs (Conover 1985). The nests of […]
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 […]

First atlantic records of the red-footed booby sula sulaand brown booby s. leucogaster in southern africa
Brown Booby (Sula leucogaster) Science Article 12 abstract The Red-footed Booby Sula sula and the Brown Booby S. leucogaster occur in most tropical seas (Harrison 1983). Both species have been recorded previously in the southern Africanregion (Maclean 1993, Hockey et al. 1992, 1996). Three additional records are reported here for the Red-footed Booby and one […]
Nazca booby sula granti and brewster’s brown boobysula leucogaster brewsteri in the hawaiian islandsand johnston and palmyra atolls
Brown Booby (Sula leucogaster) Science Article 3 abstract Nazca Booby (Sula granti) and Brewster’s Brown Booby (S. leucogaster brewsteri) are tropical sulids that normally occur only in the easternPacific Ocean. In this paper, we report on recent observations of Nazca Booby and Brewster’s Brown Booby in the Hawaiian Islands, includingthe first apparent nesting records, and […]

Survival of brown boobies (sula leucogaster)at johnston atoll: a long-term study
Brown Booby (Sula leucogaster) Science Article 6 abstract Survival of Brown Boobies (Sula leucogaster) at Johnston Atoll was examined overa 17-year period using capture-mark-recapture analysis. Annual adult survival was estimatedto be 0.90
