Barriers to gene flow are represented by historical geology and vicariant events that interrupt gene flow which are intrinsically associated to the formation and maintenance of most phylogeographic breaks. The Vitória and Trindade chain (latitude 20.5º S) is likely the main geographic barrier to gene flow for marine organisms from the Brazilian coast. This region splits the Brazilian coas…
Inferring how the historical relationships between populations are reflected on the genetic variability is one of the main challenges on the landscape genetics field. This approach allows the understanding of the relationships between geographic distribution and gene flow with the cumulative environmental and bionomics data. One of the main possibilities on the landscape/seascape approach…
The Nemertea phylum comprises about 1300 species, mostly marine, distributed worldwide. Most of these species has few aspects from their bionomic characteristics known. In addition, this is a taxonomically challenging group as there are few reliable morphological traits for the species identification. This explains that 60% of the genera are considered monotypical and the frequently found…
Natural population studies considering the effect of environment and geography over the organisms distribution and dispersal capability is the core of landscape genetics. Inferring how the historical relationships between populations are reflected, on the genetic variability is one of the main challenges on the landscape genetics field. This approach allows the understanding of the relati…
Rhinotragini Thomson, 1861 is a mimetic tribe of exclusively American wasps that has an inconsistent classification of its genera, such as "Chariergodes" Zajciw, 1963, which, like the others, was classified based entirely on traditional taxonomy, through the analysis and comparison of morphological characters. With this in mind, the tribe Rhinotragini (Cerambycidae) will be investigated b…
Sea anemones of the Order Actiniaria are polypoid marine invertebrates that have developed numerous evolutionary innovations crucial for maintaining diversity and adapting to various habitats. Nevertheless, studies on individuals of this order are more common with species from temperate regions. As a result, evolutionary, ecological, developmental, and even taxonomic aspects are sparse fo…
Ozobranchidae Pinto, 1921, one of the first leech families to diverge within Hirudinea, includes two marine genera (Ozobranchus and Bogabdella) and one exclusively freshwater genus (Unoculubranchiobdella), a total of eleven species parasitic on chelonians. Ozobranchus species are found in sea turtles (Chelonia mydas and Caretta caretta) on the Brazilian coast and are often associated wit…

Barriers to gene flow are often represented by historical geological vicariant events that interrupt gene flow between populations, promoting genetic differentiation. Barriers to gene flow are intrinsically associated with the formation and maintenance of most phylogeographical breaks observed until current days. The Vitória-Trindade seamounts chain (latitude 20.5º S) is one of the main g…
Epibiosis is the ecological relationship where an organism is used as a substrate for another without feeding on it. Several species of barnacles are epibionts or obligatory parasites of marine organisms, such as cetaceans, especially the barnacles of the Coronulidae family. In this family, the species Coronula diadema and Xenobalanus globicipitis can be interesting models in the study of…
The project "Seascape genetics and comparative genomics: an integrative evolutionary approach in marine invertebrates" demands molecular analyzes of marine invertebrates to understand which and how evolutionary events better explain the distribution of genetic variability. It is known that the benthic fauna represents most of the animal diversity and, for this reason, the levels of metazo…

Inibição da replicação viral por hospedeiros de patógenos é um processo essencial da resposta imune inata e muitas vias estão associadas a esta função em Metazoa. Em invertebrados, há quatro vias principais da imunidade inata intracelular contra vírus: sintase cíclica GMP-AMP (cGAS), receptores do tipo RIG-I, receptores do tipo Toll (TLRs) e RNA de interferência (RNAi). Contudo, a evoluçã…
In the marine environment, understanding the ecological and evolutionary dynamics of marine vertebrates poses inherent challenges. Parasites play a pivotal role in elucidating the intricacies of these interactions. Among such parasites, 'whale lice', obligatory ectoparasites found on whales and dolphins, are of particular interest. These crustaceans undergo direct development and rely on …
Many factors, both demographic and geographic, can influence connectivity in animal populations. Among the demographic factors, the type of reproduction, especially the larval development, can influence population connectivity. It is largely accepted that species with planktotrophic larvae have longer pelagic duration then species with lecithotrophic larvae. Consequently, populations of s…
