“…Alcatrazes Archipelago (24°06´S– 45°41´W; 2009) is included in the DELTA area established by the Brazilian Navy for military exercises and is the site of three expeditions. This natural environment is considered the largest nursery of seabirds in southeastern Brazil and one of the most biodiverse island environments [ 7 ]. Only a small section of the archipelago is protected and included in the Ecological Station of Tupinambás (ESEC Tupinambás), but the 34 frigates were captured and sampled on the main island, which is not protected.…”

Seabirds may be responsible for the spread of pathogenic/resistant organisms over great distances, playing a relevant role within the context of the One World, One Health concept. Diarrheagenic E. coli strains, known as STEC (shiga toxin-producing E. coli), and the extraintestinal pathogenic E. coli (ExPEC and the subpathotype APEC), are among the E. coli pathotypes with zoonotic potential associated with the birds. In order to identify health threats carried by frigates and to evaluate the anthropic influence on the southern coast of Brazil, the aim of this work was to characterize E. coli isolated from free-ranging frigates in relation to virulence genotypes, serotypes, phylogenetic groups and antimicrobial resistance. Cloacal and choanal swabs were sampled from 38 Fregata magnificens from two oceanic islands and one rescue center. Forty-three E. coli strains were recovered from 33 out of the 38 birds (86.8%); 88.4% of strains showed some of the virulence genes (VGs) searched, 48.8% contained three or more VGs. None of the strains presented VGs related to EPEC/STEC. Some of the isolates showed virulence genotypes, phylogenetic groups and serotypes of classical human ExPEC or APEC (O2:H7, O1:H6, ONT:H7, O25:H4). Regarding antimicrobial susceptibility, 62.8% showed resistance, and 11.6% (5/43) were multidrug-resistant. The E. coli present in the intestines of the frigates may reflect the environmental human impact on southeast coast of Brazil; they may also represent an unexplored threat for seabird species, especially considering the overlap of pathogenic potential and antimicrobial resistance present in these strains.

“…They are in the order of Pelecaniformes, and Fregata magnificens is the only species of the genus Fregata that is found on the Brazilian coast. Frigates search for food on the surface of the sea water and interact directly with other species of migratory birds and coastal fisherman communities [ 7 ].…”

“…Atlantoraja castelnaui) and belongs to two marine environmental protection areas (ICMBio, 2017), which makes it of high relevance for the environment. Thereby, although studies on fauna and floristic composition of its islands have already been conducted (e.g., da Rocha and Bonnet, 2009;Gallo et al, 2001;Gibran and de Moura, 2012;ICMBio, 2017;Muscat et al, 2014;Rolim et al, 2019Rolim et al, , 2017Visnadi and Vital, 2001), the incident waves pattern and its power distribution around the main island, Alcatrazes, have not yet been studied.…”

Wave climate and power distribution around a rocky island: Alcatrazes, Brazil

et al. 2021

We investigate the distribution of the wave power around the Alcatrazes island, a protected marine reserve in southeastern Brazil, located at 20 nautical miles from the coast of São Sebastião/SP. A 14-year wave time series (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018) extracted from the global WaveWatch III model, was used to obtain the offshore wave climate. Based on the wave climate, a wave propagation model (Delft3D) was applied in order to obtain nearshore information. The most frequent waves are from the east, southeast and south, with heights between 1.0 and 2.0 m and periods of 7 to 10 s. Due to dominant wave direction incidence, the wave power is higher at the more exposed eastern side of the island, with its lee side becoming shadowed from the main wave trains. Magnitudes vary seasonally, with winter and autumn presenting more energetic southerly waves and consequent higher wave power along the rocky island. The wave power distribution is a consequence of the incident wave characteristics and the geomorphology of the island. Our findings are the first assessment of the local wave climate and wave power distribution along the rocky shores of Alcatrazes island, providing important background information for understanding different aspects of its functioning and management.
