Mr Francisco Vidal Ramirez

[one_half]P1010841[/one_half]Francisco is from Chile, where he obtained his degree of Marine Biologist at the University of Valparaiso after the completion of a thesis focused on cytogenetics of rocky shore mussels. Immediately after this, he obtained a position for 4 years at the coastal station for marine research (ECIM) from the Pontifical Catholic University of Chile, where he was involved in research that was focused on ecology, photobiology, thermal tolerance, climate change impact and fisheries of marine invertebrates, working along with interdisciplinary groups at the international laboratory of climate change (LINCGlobal) and the Mediterranean institute of advance studies (IMEDEA) in Mallorca, Spain. Ended this period, Francisco moved to Australia to join the Coral Reef Ecosystems Laboratory (CRE Lab) at the University of Queensland where he is currently undertaking his PhD under the supervision of A/Professor Sophie Dove, A/Professor Gene Tyson and Dr. Maria Byrne from the University of Sydney. His PhD project assesses the effects of different ocean warming and ocean acidification scenarios on the performance of sea cucumbers in different processes such as calcium carboate dissolution, recycling of nutrients and the interaction between these invertebrates and different communities present in the sediments they process.[one_half] [/one_half]

Ms. Veronica Radice (PhD Candidate)

Moving from Philadelphia, U.S.A. to Brisbane, Australia on a one-way ticket, Veronica began her PhD at the University of Queensland in 2014 under the supervision of Prof. Ove Hoegh-Guldberg, A/Prof. Sophie Dove, A/Prof. Gene Tyson, and Prof. Brian Fry (Griffith University).

Veronica’s interest in deep reefs was inspired by the research in the deep-sea ecology lab of Dr. Erik Cordes (Temple University), where she was a research assistant and lab manager since college graduation. Veronica graduated from Johns Hopkins University (Baltimore, U.S.A.) with a B.A. in Biology in 2012.

Veronica has a wide variety of research interests, from the shallow reefs where she can scuba dive to the proper deep sea. Her PhD research is focused on understanding how the trophic ecology of shallow and deep corals may be influenced by oceanographic processes such as upwelling, which brings important nutrients to shallow waters. Such nutrient fluxes may be important to the coral holobiont, which can utilize both dissolved and particulate food sources. Veronica is interested in learning how the coral holobiont, including its associated microbial communities, may respond to natural nutrient fluxes in coral ecosystems.

As an XL Catlin Seaview Survey Ocean Scholar, Veronica had the opportunity to conduct research in the Maldives, an archipelago in the middle of the Indian Ocean. What makes the Maldives particularly unique is the atolls’ location upon an oceanic ridge and the seasonally-reversing monsoons. This combination of bathymetry and climate makes the Maldives a great place to study the influence of oceanographic processes on coral reefs. Her research is focused on understanding how environmental differences between the shallow and deep reef may influence coral holobiont metabolism and composition.

Veronica was thrilled to recently present her work at the 13th ICRS 2016 in Honolulu, Hawaii!

Ms Michelle Achlatis

Coral reefs are the result of a constant battle between constructive and destructive forces. When it comes to biologically-driven destruction, erosion by excavating sponges is one of the most important yet understudied mechanisms. Global warming and acidification are predicted to enhance the impact of these sponges on reefs, tipping the balance to the disadvantage of corals and other calcifying organisms. Using Cliona orientalis as her model species, Michelle’s current work aims to decipher the metabolic dynamics of bioerosion and to evaluate the resilience of excavating sponges to future environmental conditions. Michelle joined the Coral Reef Ecosystems lab as a PhD student in 2014 after she finished her Master’s at the University of Amsterdam working on Caribbean reef sponges and majoring in science communication. She completed her first degree at the University of Crete in her homeland Greece.

Dr Annamieke Van Den Heuvel

Screen Shot 2015-01-12 at 1.43.24 pmAnnamieke has been with the CRE lab for a number of years, first as a Honours student and then when undertaking her PhD. During her time as a CRE student, she researched the effects increased levels of exogenous nitrogen had on the relationship between coral and their symbiotic algae, Symbiodinium. These effects were examined on both a genetic and physiological level to develop an overall picture of a coral holobionts response to increasing levels of nitrogen.

 

Currently Annamieke is the Laboratory Manager for the Coral Reef Ecosystems Lab. She helps in keeping the lab running and responds to applications to work with the lab.

A view into the Mesocosm ‘Mini-Reef’

In addition to her Lab manager role, Annamieke regularly travels to Heron Island to check and sample the mesocosm experiment currently underway. These mesocosems are representative ‘mini reefs’ comprised of several species of hard and soft coral, algae assemblages, various invertebrates and some herbivorous fish. The experiment, being run by A/Prof Sophie Dove, looks at the effects of climate change on coral reef ecosystems. The four treatments explores the effects of increased temperature and pCO2 on coral                                                   reef communities both in combination and separately.

Dr Nela Rosic (DECRA Research Fellow)

nela1Overview

I grew up in Serbia and start thinking about Science due to my love for genetics. I received a BSc (Hons First Class) in Molecular Biology and Physiology and a MSc in Plant Biology from the University of Belgrade. After moving to Brisbane, I completed a PhD at the University of Queensland. I have been awarded with a UQ Postdoctoral Fellowship for Women (2011-2013) and a prestigious Discovery Early Career Researcher Award by ARC (2012-2014).

Research Interests

  • Reprogramming Symbiodinium epigenome for higher temperature conditions
    Coral reefs represent one of the most diverse marine ecosystems housing an estimated 25% of all marine species. Exposure to thermal stress has been recognized as an important abiotic factor leading to the loss of algal symbionts from coral tissue and coral bleaching. The goal of this project is to enhance our understanding of the capacity of coral algae to tolerate thermal stress using an ancient epigenetic mechanism DNA methylation for reprogramming their epigenomes.
  • Coral algae as a source of UV-absorbing compounds
    Reef-building corals form mutualistic symbioses with unicellular photosynthetic dinoflagellate of the genus Symbiodinium. Exposure to ultraviolet radiation especially when combined with thermal stress, has been recognized as an important abiotic factor leading to oxidative stress and break down of the coral-algal endosymbiosis. In nature, many marine organisms use Mycosporine-like Amino Acids (MAAs) as biological sunscreens in UV protection and the prevention of oxidative stress. Corals acquire MAAs from their symbiotic algae and diet. Until now the complete enzymatic pathway of MAA synthesis is not known nor is the extent of their regulation by environmental conditions.
  • Transcriptomics for detection of stress in coral
    Changes to the environment as a result of human activities can result in a range of impacts on reef building corals that include reduced concentrations of algal symbionts and coral bleaching. We investigate the expression of genes in the colonies of the reef-building coral during environmental perturbations including elevated sea temperatures and nutrient enrichment. Our results will provide new insights into the transcriptional profiles of the coral holobiont and transcriptional regulation prior bleaching. In addition, we will identify a range of potential stress biomarkers that could be used for the development of the early warning signs of stress in reef-building corals.
