MOLECULAR PHYSIOLOGY 

Principal Investigator:
Jonathan Mark Wilson

The main objective of the Molecular Physiology Research Group is to understand the molecular physiological mechanisms of adaptation in fishes across evolutionary and life history time scales. This research has applications in conservation physiology and improving conditions in finfish aquaculture.

Specific objectives and research lines:

  • Elucidating the molecular mechanisms of ion and acid-base regulation in fishes. This has relevance to species conservation and in evaluating the impacts of ocean acidification.
  • Establishing a link between exposure to high environmental ammonia and increased disease susceptibility in fishes. This has relevance to both aquaculture and environmental monitoring.
  • Determining the importance of acid-peptic digestion in the evolution of the stomach in vertebrates using fish models. This has relevance to aquaculture.

Our current research addresses the Horizon 2020 societal challenges (1) Food security, sustainable agriculture and forestry, marine and maritime and inland water research and the bioeconomy and (2) Climate action, environment, resource efficiency and raw materials.
