Dynamic Vision: from Single Photons to Behaviour in Extreme Light Environments

Vacancy Reference Number: Link
Closing Date: 24 Nov 2024
Salary: According to the pay-scale for University employees (TVL)
Address: Konstanz / Radolfzell
Duration: 3 Years

The Visual Neuroethology group headed by Dr. Anna Stöckl is recruiting a PhD candidate to study the dynamic visual abilities of nocturnal moths. Our growing lab at the University of Konstanz focuses on how insects process information for flower selection and movement control in varying light environments. We approach these questions using a combination of neurophysiology, neuroanatomy, quantitative behavioural methods, and computational tools.

Driving along a tree-lined avenue, we have all experienced how the rapid succession of light and shade disrupts our vision. Such conditions push even synthetic sensors to their limits, but many animals master these challenges on a daily—and nightly—basis. Indeed, a high dynamic range is a hallmark of natural sensory environments. For nocturnal animals, artificial light at night makes this range even more extreme and poses a considerable challenge to their visual system. How then is dynamic visual information processed with the limited bandwidth available in neural circuits? And what role do an animal’s movements, which shape what it sees, play in matching the acquired information to the limited processing capacity? The visually-guided flight of nocturnal moths is uniquely suited for approaching these questions.

In this project, the PhD candidate will study the mechanisms underlying vision in dynamic light environments. The elephant hawkmoth (Deilephila elpenor) currently serves as a focus species. In this project, we plan to expand our investigations comparatively to other nocturnal moths. To dissect the neural basis of natural behaviour in dynamic light, the project will have a strong focus on quantitative behavioural measurements of the moths’ free flight in different light intensities, using newly established motion-capture tracking in a large flight arena.

Depending on the candidate’s qualifications and interests, neurophysiological measurements of motion processing neurons, or outdoor behavioural experiments in natural light conditions, can complement this approach. Integrated into an expanding group in the international environment at Konstanz University, this research project will pioneer our understanding of how nocturnal insects cope with dynamic light environments, including artificial light pollution.

The position:

• The position is initially available for three years, with the possibility for extension.
• Salary according to the pay-scale for University employees (TVL).
• Graduation via the IMPRS-QBEE graduate program.

You will be part of an international research group, integrated into the vibrant research community.

Applicants should apply via the IMPRS’ application system. In addition to the documents specified in the system, applicants are required to include a research statement addressing the following prompts:

• Describe your main scientific interests, how they developed, and how they relate to the proposed research project. Explain what types of scientific questions most motivate you and why. (1 page)
• Describe 1-2 specific biological questions or hypotheses you would like to test within the described project. You should assume that you will have access to existing data as well as the opportunity to collect new data. Explain what data you would collect (and/or use) and the analytical approach(es) you would employ to address your questions. (1 page, excluding any references)
