Sexual Differentiation in P. panamensis
Sexual Differentiation in P. panamensis

Male and female corals are performing differently in response to low-pH in the Gulf of California. I aim to understand this sexual dimorphism by investigating the genes that contribute to this different performances.

E. flexuosa occurs both in shallow and deep waters, but it shows two separate morphologies. In shallow waters (left picture), the branches are all much closer to each other, while in deep waters the branches are longer and more spindly. We aim to identify regions of genomic divergence between these ecotypes along a depth gradient through Fst outlier analyses.

In the Gulf of California, Porites panamensis occurs throughout. It serves the same ecological role as its Panamanian counterpart, and it shares the same morphology. However, some recent ddRADseq data has shown the Gulf of California P. panamensis is more closely related to an ecologically distinct, morphologically distinct species, P. sverdrupi.
I aim to investigate the areas of genomic divergence within these three species with Fst outlier analyses between each comparison.
