Genomics of mimicry in Neotropical Corydoras catfishes (TAYLORU20DTP)

Project Description

Mimetic relationships - where two or more species share colour patterns to reduce attacks by predators are some of the most powerful demonstrations of natural selection in nature. This project will investigate the genetic basis of traits involved in mimicry in freshwater Neotropical Corydoras catfishes. Corydoras catfishes are frequently involved in mimetic relationships with one another and a large diversity of colour patterns exist in nature which make them very popular aquarium fishes.

This project aims to investigate the genetic basis of coloration involved in mimicry and use a suite of genetic methods to identify signals of selection in the genomes of the different species. The project will use existing whole genome sequences and whole genome resequencing (WGS) coupled with cutting edge bioinformatic analyses to identify genes associated with colour pattern mimicry in these fishes. State-of-the-art molecular facilities are available at UEA and the broader Norwich Research Park (NRP), along with aquarium facilities and a high performance computing cluster.

The applicant should have a strong background in genetics / evolutionary biology and have an aptitude for both laboratory work and bioinformatic analyses – although training will be provided.

This project has been shortlisted for funding by the Norwich Biosciences Doctoral Training Partnership (NRPDTP). Shortlisted applicants will be interviewed as part of the studentship competition. Candidates will be interviewed on either the 7th, 8th or 9th January 2020.

The NRP DTP offers postgraduates the opportunity to undertake a 4-year research project whilst enhancing professional development and research skills through a comprehensive training programme. You will join a vibrant community of world-leading researchers. All NRPDTP students undertake a three-month professional internship (PIPS) during their study. The internship offers exciting and invaluable work experience designed to enhance professional development. Full support and advice will be provided by our Professional Internship team. Students with, or expecting to attain, at least an upper second class honours degree, or equivalent, are invited to apply.
