significant threat to marine biodiversity and resources worldwide.
In Brazil, the invasive coral Tubastraea spp. (sun-coral) has been
recorded on oil platforms since the late 1980s. However, the
influence of these artificial marine structures in the dispersal
process of the sun-coral has not yet been assessed on a regional
scale, along the Brazilian coast. Thus, this work aims to
comprehend the role of oil platforms, located on oil-producing
Brazilian basins, in the natural dispersion of sun-coral larvae on
the Brazilian coast. The natural dispersion patterns of sun-coral
larvae were estimated by biophysical simulations in the biological
individual-based model Ichthyop (v.3.3.6), which, besides
considering the biological characteristics of the organism, it
employs solutions of the Regional Oceanic Modeling System (ROMS)
as input physical parameters. The ROMS solutions represented the
main oceanographic processes operating in the Southwest Atlantic
and their seasonality, hence guaranteeing the reliability of the
biophysical simulations. At Ichthyop, the oil platforms were
grouped into zones where 70,000 larvae were released in each
90-day simulation, for the southern summer and winter in the
period of 6 years (2010-2015). The results of the biophysical
modeling pointed out no larval mortality due to thermal
intolerance. The southernmost position of the Southern Equatorial
Current south branch in the winter expands the number of receiving
zones released from the Sergipe-Alagoas and Camamu Basins towards
the north. All the oil-producing Brazilian basins analyzed are
capable of providing sun-coral larvae to the Brazilian coast. The
oil platforms of the Cear{\'a}, Potiguar, Sergipe-Alagoas and
Camamu Basins are the main suppliers, possibly due to their closer
location to the coast. Although the entire Brazilian coast is
susceptible to the sun-coral larvae arrival, the
Par{\'a}-Maranh{\~a}o and Bahia coast receive the largest
numbers of larvae (66.39% and 11.76%, respectively). The results
indicate that several Brazilian ecosystems are vulnerable to the
arrival of suncoral larvae, including the Amazon Reef System and
the Abrolhos Bank. The oil platforms presented themselves as
possible chronic sources of sun-coral propagules for the Brazilian
coast, emphasizing the urgency in the measures of control and
monitoring of this invasive exotic species in the country.",
