Two ocean acidification PhD positions will be available at the Leibniz Center for Tropical Marine Ecology (ZMT) in Bremen/Germany

Two ocean acidification PhD positions will be available at the Leibniz Center for Tropical Marine Ecology (ZMT) in Bremen/Germany beginning this year. Please find below the details for each position and contact details. A first tentative deadline for applications is March 15.

The Leibniz Center for Tropical Marine Ecology GmbH (Leibniz-ZMT GmbH; in Bremen is a member of the Leibniz Association, which is supported by the German Federal and State Governments. Through its research, Leibniz-ZMT GmbH contributes to developing science-based strategies for sustainable use of tropical coastal ecosystems such as mangroves, coral reefs, sea grass meadows as well as rivers, estuaries and the adjacent coastal waters. It addresses issues related to the functioning of these habitats, their interactions with the hinterland and the open ocean as well as their response to anthropogenic interventions and climate change. To cover the entire complexity of interactions between humans and the environment, the ZMT conducts research with an interdisciplinary approach which includes both natural science and social science working groups.

Effects of environmental change (nutrification, acidification) on calcareous green algae

The PhD student position will be part of the working group at ZMT focusing on the effects of environmental change (nutrification, acidification) on carbonate secreting communities. The PhD project will focus on calcareous green algae in various modern tropical environments. We are looking for a student with a background in carbonate sedimentology and/or marine botany.

– MSc or equivalent degree in geology or biology
– basic analytical skills in carbonate sedimentology

Physiological and ontogenetic responses of tropical benthic calcifiers towards changing environments

Marine flora and fauna are facing ocean acidification, rising water temperatures and other stressors, particularly in tidal and estuarine environments. The aim of the project is to understand how selected tropical calcifying species from different phyla (coralline algae, coral, crustacean, mollusc) respond to single and combined effects of abiotic stressors in their environment. The study will focus on physiological (e.g. photosynthesis, respiration and calcification) and ontogenetic (e.g. development, growth and survival) responses of organisms and their critical tolerance levels to multiple stressors.

– ecophysiological background with experience in performing lab experiments with marine organisms and sound practical skills regarding their cultivation
– willingness to conduct research in the tropics, making previous field experience desirable
