PhD position in aquatic science
Position type: PhD position
Location: University of Geneva (Switzerland)
Application deadline: 2021-05-20
The PhD will work on a 4-year project aiming to explore the impact of nano- and microplastics of different composition in freshwater ecosystems. The specific emphasis will be on the understanding the nano-, microplastic-induced effects on the planktonic species at the base of the food web, such as phyto- and zooplankton and possible consequences for ecosystem services and biogeochemical cycles. In this project we have a specific interest to see how the ecotoxicological effects play out at the community level – within and between the 2 plankton communities – since this enhanced biological complexity brings the experimental work an important step closer to the field.

The work is experimentally oriented and will involve lab, controlled microcosm and field experimentation, use of ecotoxicity bioassays and molecular techniques. This interdisplinary project is at the interface of two core research topics at the Natural Science Hub of the Institute for Environmental Sciences: water and biodiversity and will be developped in close collaboration of two research teams Environmental Biogeochemistry and Ecotoxicology led by prof. Slaveykova and Microbial Ecology led by prof. Ibelings.

Postdoctoral position - Understanding and Predicting Cyanobacteria Genetics and Toxin Production
Position type: Postdoctoral Position
Location: Rensselaer Polytechnic institute - Troy, NY (USA)
A postdoctoral scientist position is available associated with the Jefferson Project at Lake George to address the biotic and abiotic stressors in freshwater bodies of water that drive harmful algal blooms (HABs). HABs involve the proliferation of cyanobacteria (i.e., blue-green algae) to the point where they dominate freshwater lakes, with several species producing harmful toxins (e.g., liver toxins, nerve toxins, and skin irritants) that impact ecosystems, humans, livestock, and pets. While HABs can occur naturally, their occurrence and magnitude have dramatically increased throughout the world. Despite decades of research, there is a major knowledge gap regarding the conditions that trigger cyanobacteria to produce toxins. To address the science and solutions of HABs, we have assembled a multidisciplinary team to examine the triggers of HAB formation and toxin production in cyanobacteria in multiple lakes.

The postdoctoral scientist will work with biologists, chemists, and biochemical engineers to perform lab and field experiments to understand the role of genetics, gene regulation, and the environmental factors that cause cyanobacteria to bloom and produce toxins. This work will entail characterizing the microbiome associated with HAB cyanobacteria, identifying microbial species that affect HABs and toxin production, characterizing the genomes of globally relevant HAB cyanobacteria, and further identifying the genes and biochemical pathways responsible for toxin production.

The starting salary is $51,000 with excellent health benefits. The post-doc will be based on Main Campus in Troy, NY, which has a thriving downtown that includes excellent restaurants, coffee shops, and a farmers market. Main Campus is also in close proximity to the Adirondack and Catskill Mountains and their associated lakes, with many fun recreational opportunities.

Candidates should have a Ph.D. in the biological sciences with experience in transcriptomic and metagenomic analysis or related areas. Interested individuals should provide a cover letter, CV, research statement, and a list of 3 references to Prof. Rick Relyea ( as a single pdf. Open

Doctoral researcher - Regime shift in the plankton community of Lake Konstanz
Position type: PhD scholarship 4 years (DAAD stipend)
Location: Limnological Institute at the University of Konstanz
Call for applications for a PhD scholarship (4 Years) integrated in the Research Training Group R3 at the University of Konstanz.

A PhD scholarship funded by the DAAD is available for the following research topic:
Understanding of the regime shift in the phytoplankton community in Lake Constance: Seasonal and inter-annual changes in the traits of the plankton community

Project Description: Trophic change has caused a regime shift in the annual phytoplankton biomass in Lake Constance. During eutrophication between the 1960s and the 1980s and during re-oligotrophication from the 1990s onwards the annual phytoplankton biomass has been rather resilient to changes in nutrient concentrations except for a comparatively short time period of transition between the two alternative states. The project aims at a better understanding of the mechanism responsible for the resilience and the regime shift of the phytoplankton in Lake Constance. We plan to use data analysis, and possibly also numerical modelling, of the phytoplankton community to investigate the consequences of changes in bottom up and top-down effects on the seasonal course of plankton development during eutrophication and re-oligotrophication. The project is integrated in the Research Training Highly motivated candidates with a MSc degree in biology, mathematics, oceanography, physics or engineering are welcome to apply. Applicants should have a background in numerical modelling and data analysis, ideally experiences with environmental systems and plankton, and show an enthusiasm for basic research.
