Martina Prazeres

I am a marine biologist interested in the biology, ecology, and evolution of reef organisms, with a particular emphasis on symbiont-bearing Foraminifera. I completed my PhD at the University of Queensland, Australia, working on the responses of benthic foraminifera to the effects of environmental changes. I joined Naturalis as a Veni fellow, and my current project aims to unveil the evolutionary mechanisms of adaptation to changes in foraminifera.

Research
interest

My research interest lies mainly in the biology, ecology and evolution of the symbiotic relationship between reef organisms and microbial associates, and how this relationship helps shaping coral reefs.

My research focuses on the evolution, genetic diversification, and symbiosis of large benthic Foraminifera. In addition, I study associations between foraminifera and their microbial associates in coral reef environments. I am particularly interested in large scale patterns associated with environmental gradients, such as water quality and sea-surface temperature.

My paper has been featured in the University of Leiden newspaper! Turns out symbiont-bearing Foraminifera also bleach in response to ocean warming. Results were published in the journal Frontiers in Microbiology (check it out here).

You can check out the story in the Mare newspaper: Gif op het rif.
