The taxonomic richness and distributional patterns of the macrofauna associated with the algae genus Dictyota from the Abrolhos Bank (Eastern Brazilian coast) are analyzed. Macrofauna comprised a total of 9586 specimens; a complete faunal list of the most abundant taxa (Crustacea, Polychaeta and Mollusca, accounting for 95.6%) resulted in 64 families and 120 species. Forty six species are registered for the first time for the Abrolhos Bank, of which 3 are also new for the Brazilian coast. The most abundant families were Ampithoidae amphipods (with Ampithoe ramondi as the main faunal component), Janiridae isopods, Rissoellidae gastropods and Syllidae polychaetes. Comparisons were made between summer and winter periods and among sites from Sebastiao Gomes Reef, near the coast, and from Siriba Island, in the Abrolhos Archipelago, away from the mainland. Algae size was lower in the summer, when faunal density was higher, suggesting a possible effect of grazing. Macrofaunal communities were significantly different among sites and periods. Coastal and external communities were markedly different and winter had the greatest effects on the fauna. Environmental conditions related to sediment type and origin and turbidity appear to be a good scenario for our macrofauna distribution results.
Just got the wonderful news that my application was selected for a Faculty for the Future Fellowship! Recipients are women in STEM fields who may become role models in the sciences upon returning to their home countries. The fellowship will fund the last year of my PhD at Harvard, working with the phylogenetic relationships of gastropods, their biogeography in the marine environment and the evolution of shell shape across large time scales.
After a great semester with many leading researchers coming to talk to us about all sorts of topics and software on phylogeography and phylogenomics, I got the Certificate of Distinction in Teaching from the Derek Bok Center for my work at 'Phylogenetics and Phylogeography in the Era of Genomics' (OEB275r) last Fall!
