Fabio Cortesi

This Thursday, 13:00 GMT+1 (1pm UK, 2pm Europe) we have the Sussex Vision series coming back. Tune in at m.youtube.com/playlist?lis... to hear Fabio Cortesi talk about vision in coral reef fishes. See you there!

We're hiring a postdoc!👀
Join us to explore the amazing world of (deep-sea) fish vision! We're looking for a curious researcher to work with histology, FISH, and even crispr!
Apply by 14 July 2025.
Thks for sharing!

CrossFilt: A Cross-species Filtering Tool that Eliminates Alignment Bias in Comparative Genomics Studies Comparative functional genomic studies are often affected by biased read mapping across species due to inter-species differences in genome structure, sequence composition, and annotation quality. We d...

We developed CrossFilt, a read-level, cross-species filtering approach that avoids these errors without sacrificing usable data. It outperforms all existing strategies and exposes just how much signal in comparative genomics has been misread.

The planktonic microbiome of the Great Barrier Reef Large genome databases have markedly improved our understanding of marine microorganisms. Although these resources have focused on prokaryotes, genomes from many dominant marine lineages, such as Pela...

Very excited to present the Great Barrier Reef Microbial Genomes Database (GBR-MGD), a comprehensive DB of 1000s of high-quality prokaryote, virus, plasmid, and chromosome-level eukaryote MAGs using Nanopore long reads. Subthreads incoming. Please share widely. 🙂

3/3 Once the larvae have hatched they enter a 10-14 day pelagic phase where they need to feed like crazy on various types of zooplankton (copepods, rotifers and brine shrimps in the lab) before they return to the reef, or in our case the pot, to settle and metamorphose into a mini #nemo

2/n Once the eggs have been successfully fertilised, they will turn black after 2-3 days as the embryos begin to develop their black pigment in the skin.

After ~8-10 d the eyes start silvering up and the embryos will hatch shortly thereafter, this usually occurs at night. See next post for larvae

1/n Amphiprion percula aka #nemo ready to spawn. This is one of our most proficient breeding pairs in the University of Queensland breeding colony. The female will adhere her eggs to the pot for the male to fertilise —> see next post

A standardized nomenclature for the rods and cones of the vertebrate retina Vertebrate photoreceptors have been studied for well over a century, but a fixed nomenclature for referring to orthologous cell types across species has been lacking. In this Consensus View, the autho...

1/7 Variation between individuals is important as it determines how adaptable to change a population might be. Even generalist spp are often comprised of specialist individuals, but specialisation is often only studied across single traits which is limiting.
