Brown Booby (Sula leucogaster) Science Article 5 abstract species of the Sulidae family, which comprisesgannets and boobies (Carboneras 1992).Brown Boobies are pan-tropical birds thatnest on a wide variety of habitats (Dorward1962a, 1962b; Skutch 1976, Nelson 1978).Brown Boobies nest on much steeper terrainthan most boobies and gannets (Nelson 1978,Carboneras 1992); for this reason, it seemsthat this […]

Brown Booby (Sula leucogaster) Science Article 13 abstract Hematologie and serum chemistry values are reported for 105 brown boobies (Sula leucogaster) from Johnston Atoll, Central Pacific. Hematocrit, estimated total plasma solids, total and differential white cell counts, serum glucose, calcium, phosphorus, uric acid, total protein, albumin, globulin, aspartate aminotransferase, and creatinine phosphokinase were analyzed. H?matologie […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
