Marine studies


Dalit Meron is a marine ecologist and microbiologist researching the microbial communities in the marine surrounding. She is part of the Research Fellows team at the Morris Kahn Marine Research Station (MKMRS) and manages the Long Term Ecological Research of the sediment and microbiome projects. Her research focuses on: (1) The holobiont concept and symbiotic relationships under environmental changes, understanding the role of the associate microbial members on the host health and disease and their impact on the acclimation and host tolerance under stresses. These studies included a variety of organisms including corals, sea anemones, fish and sharks. (2) Monitoring and characterizing the sediment microbial communities along the continental shelf of east Mediterranean Sea in order to examine health site and further changes following environmental changes and anthropogenic impacts. (3) Develop a microbial-molecular indicator to monitor the sediment environment. Her work includes microbiological techniques, molecular biology and bioinformatics analysis of NGS and metagenomics.



Current Research:

  • Continue monitoring the sediment microbiota along the continental shelf.
  • Shark microbiota at a unique mix-species shark aggregation site
  • Respiratory, gut and skin microbiome of loggerhead (Caretta caretta) and green (Chelonia mydas).
  • Microbiome and ecophysiology of marine pelagic copepods under environmental and anthropogenic stressors
  • Analysis of the impact of global warming and low primary production on the metabolic rate of the holobiont Brachidontes pharaonis using dynamic energy budget theory.
  • Conomurex persicus microbiome and physiology under anthropogenic enrichment
  • Lionfish microbiome – their role in the success of the invasion.
