Dr Jolyon Troscianko, University of Exeter

Location: Centre for Ecology and Conservation, Penryn Campus, Cornwall

The University of Exeter’s Centre for Ecology and Conservation is inviting applications for a PhD studentship fully-funded by the Royal Society and the Faculty to commence on 23 September 2024 or as soon as possible thereafter. For eligible students the studentship will cover Home or International tuition fees plus an annual tax-free stipend of at least £19,237 for 4 years full-time, or pro rata for part-time study. International applicants need to be aware that you will have to cover the cost of your student visa, healthcare surcharge and other costs of moving to the UK to do a PhD.

Project Description:

Many animals use signals of colour or size as indicators of quality in mate choice and male-male conflict. It is often assumed that these signals are processed linearly, where an increase in signal size results in a commensurate increase in perceived quality. However, signals are often not perceived linearly, due to sensory processes such as visual illusions, signal categorisation, and proportional processing. This project aims to quantify these processes in poeciliid fishes, with a particular focus on sensory processing during mate choice and male-male interactions. By investigating how these processes are affected by biotic and abiotic environmental factors, we will determine how sensory processes and signalling environment can affect signal form, behavioural outcomes, and the evolution of visual signals.

Using discrimination tasks, automated fish tracking and artificial evolution experiments, this project will address fundamental questions about the importance of perceptual processing during signal assessment. The successful candidate will have an interest in visual ecology, sexual selection and animal behaviour, previous experience working with fishes is not essential.

Entry requirements

Applicants for this studentship must have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK, in an appropriate area of science or technology. 

If English is not your first language you will need to meet the required level as per our guidance at https://www.exeter.ac.uk/pg-research/apply/english/

In the application process you will be asked to upload several documents. 

• CV

• Letter of application (outlining your academic interests, prior research experience and reasons for wishing to undertake the project).

• Transcript(s) giving full details of subjects studied and grades/marks obtained (this should be an interim transcript if you are still studying)

• Names of two referees familiar with your academic work. You are not required to obtain references yourself. We will request references directly from your referees if you are shortlisted.

• If you are not a national of a majority English-speaking country you will need to submit evidence of your proficiency in English.
