THE CHEWING LICE OF BROWN BOOBY (SULA LEUCOGASTER) IN SOUTHEASTERN BRAZIL.

Journal of Parasitology, 2022
The brown booby (Sula leucogaster Boddaert, 1783) has a wide geographic distribution, being found throughout the intertropical range except for the west coast of South America. Chewing lice (Phthiraptera: Amblycera and Ischnocera) are ectoparasites commonly found in association with a wide variety of bird species, and extensive infestations can lead to

Incidence of anthropogenic material in Sula leucogaster nests in a distant archipelago of Brazil

Marine Pollution Bulletin, 2020
Anthropogenic debris has been affecting fauna in different ways. We investigate the frequency of anthropogenic material in nests of a brown booby (Sula leucogaster) colony in the Saint Peter and Saint Paul Archipelago (SPSPA), Rio Grande do Norte, Brazil in February 2015 and November 2016. The items were classified according to type (threadlike plastic,

Prevalence and composition of marine debris in Brown Booby (Sula leucogaster) nests at Ashmore Reef

Marine Pollution Bulletin, 2013
Anthropogenic debris is ubiquitous in the marine environment and has been reported to negatively impact hundreds of species globally. Seabirds are particularly at risk from entanglement in debris due to their habit of collecting food and, in many cases, nesting material off the ocean's surface.

Ventral feathers contained the highest mercury level in brown booby (Sula leucogaster), a pantropical seabird species

Chemosphere, 2022
Seabirds are extensively used as environmental biomonitors and feathers are among the most analyzed matrices because they are one of the main excretory pathways to detoxify the bird's body of environmental contaminants. Still, there is a variation in contamination level between the different feathers of seabird species, driven by diet and physiology ...

Causes of Fatal Cyathostomiasis in Brown Booby (Sula leucogaster) from Brazil: Identification of Pathogen and Implications for Management

Journal of Parasitology, 2020
Fatal infection by Cyathostoma (Cyathostoma) phenisci (Nematoda: Syngamidae), was identified in 2 of 52 brown boobies (Sula leucogaster) collected on beaches in the state of Rio de Janeiro, Brazil, and admitted to the veterinary clinic for rehabilitation.

Comparative phylogeography of brown (Sula leucogaster) and red-footed boobies (S. sula): The influence of physical barriers and habitat preference on gene flow in pelagic seabirds

Molecular Phylogenetics and Evolution, 2010
To test the hypothesis that both physical and ecological barriers to gene flow drive population differentiation in tropical seabirds, we surveyed mitochondrial control region variation in 242 brown boobies (Sula leucogaster), which prefer inshore habitat, and 271 red-footed boobies (S. sula), which prefer pelagic habitat.

Promiscuous Brown BoobySula leucogasterFemales Perform Reverse Mounting

Ardeola, 2014
Summary. Reverse mounting (RM), i.e. where the female mounts the male, has been recorded in some bird species, yet the potential function of this behaviour is not clear. Here, we describe the frequency of RM in the brown booby Sula leucogaster and the behavioural context in which it occurs.

Lymphomas in seabirds: case reports in a black skimmer (Rynchops niger) and a brown booby (Sula leucogaster)

Journal of Comparative Pathology
A black skimmer (Rynchops niger) and a brown booby (Sula leucogaster) were rescued and gross, histopathological, immunohistochemical and polymerase chain reaction evaluations were conducted to investigate the cause of death. There were neoplastic infiltrations of CD3+ PAX5- lymphocytes in the black skimmer and CD3- PAX5+ lymphocytes in the brown booby.
