Making a choice for life – Cellular and molecular basis of coral larvae settlement and metamorphosis.
This project aims to investigate the role of biofilms in larval recruitment of cold-water corals using advanced techniques to understand their sensory biology and response to environmental changes.
Projectdetails
Introduction
Corals form the basis for some of the most diverse marine ecosystems on the planet. Yet these unique ecosystems have suffered tremendous harm due to anthropogenic influences and are predicted to be among the most adversely affected habitats under the foreseen changes in climate.
Impact of Climate Change
Among these changing conditions are the occurrence and composition of microorganisms in the coral’s habitat, which are affected by changes in temperature and pH. Corals associate with several specific microorganisms that govern central aspects of their complex lifecycle, such as the recruitment of larvae, a process that ensures health and resilience of coral reefs.
Research Gap
While the central role of biofilms is established in tropical coral species, the vast deep-sea cold-water coral species are less well studied. Lophelia Pertusa is a framework-forming cold-water coral with a global distribution and important ecosystem function. However, whether larval recruitment depends on biofilm abundance and composition is unknown.
Urgency of the Study
It is therefore urgently required to study this fundamental process in cold-water species to assess and mitigate environmental threats to this unique ecosystem.
Proposed Study
The proposed study will pioneer investigations into the mechanistic basis of cellular and molecular signal recognition in cold-water coral larvae, taking advantage of the specialized settlement behavior and recent advances in sequencing technology.
Methodology
Here, I will use an interdisciplinary approach, at the border of bacterial recognition, development, and sensory biology. I will combine the power of:
- Single cell patch clamp electrophysiology
- Behavioral analysis
- Molecular analysis
to address central questions about sensory biology in cold-water corals.
Expected Outcomes
Thereby, the project will produce fundamental knowledge about coral habitat selection that is urgently required to understand which impact environmental changes have on this central process.
