Sex-specific foraging behaviour in tropical boobies:does size matter?

Brown Booby (Sula leucogaster) Science Article 1 abstract Sex differences in the foraging behaviour of adults have been observed in a number ofsexually size-dimorphic birds, and the usual inference has been that these sex-specificdifferences are driven primarily by differences in body size. An alternative explanation is thatforaging differences result from sex differences unrelated to size, …

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 …
