Overview

As an aquatic biogeochemist, my interest revolves around the interactions between organisms and their environment, with emphasis on trace metal bioavailability to phytoplankton and redox transformations. I am intrigued by the fact that microorganisms, striving to acquire nutrients and protect themselves from external stressors, actively modify their chemical milieu and in turn influence the biogeochemical cycles of trace and major elements in the ocean. I study fundamental processes and mechanisms by combining field and laboratory measurements and experiments.

Coral reef biology in a changing environment. Ecological and physiological responses of subtropical and tropical marine communities to environmental stress. Understanding symbiosis of cnidarians with their associated endosymbiotic algae, endolithic and epilithic communities and the way this symbiosis changes under elevated seawater temperature, increased radiation and decreased pH. How will coral reef ecosystems change following a shift in the environmental conditions in which they developed as projected by climate change trajectories? How interactions between acute and chronic disturbances influence the integrity of our planet's richest marine environment?

Rising levels of carbon dioxide in Earth's atmosphere are inducing significant changes in the marine environment. Particularly alarming is an observed rapid increase in sea surface temperature. Corals already live close to their upper thermal limit on most reefs and so additional warming is predicted to severely threaten their survival. Coral reefs are extremely economically (tourism, fishing) and environmentally (diversity, productivity) valuable. Therefore is it of utmost importance to urgently understand corals' response to global climate change and to identify and protect regions which may be resilient to change.

The Gulf of Aqaba has been putitatively identified as a such region where corals may exhibt increased thermotolerance. A refuge.

My research aims to investigate this reef refuge hypothesis further using dominant reef building corals on Eilat's reefs. I use the Red Sea Simulator experimental system in Prof. Fine's lab at the IUI to expose corals to near future predicted climate change senarios. I predominantly assess the physiological response to temperature stress to better under the thermal physiology of corals in the Gulf of Aqaba. In addition I am interested in the transgenerational aquisition of physical traits and how the experience of a parent colony can influence the early ontogeny and environmental plasiticity of offspring.

I am currently a Ph.D. student within the Life Sciences department at Bar Ilan University supervised by Prof. Maoz Fine.
