Monika Winder, Professor, Stockholm University


My research interest is in the consequences of environmental change for food webs and ecosystem functions. My research addresses questions in lakes, estuarine-coastal and ocean ecosystems with a special emphasis on planktonic organisms. I conducted post-doctoral research at the University of Washington, Seattle, and at the University of California Davis, and received my PhD in Natural Sciences from the ETH in Zürich.

Baptiste Serandour, Ph.D. student, Stockholm University


I am a PhD student in marine biology at Stockholm University. I am interested in the food web interaction between primary producers and consumers. I use selective DNA barcoding and network modelling to investigate food web structure under changing environmental conditions. This project is connected to the VR project: Consequences of zooplankton feeding strategies on the function of marine ecosystems.


Noah Ngisiang’e, Ph.D. student, Stockholm University



My study aims to assess the impacts of environmental change on fish larvae productivity in seagrass habitats in Kenya and Tanzania. The studies investigate drivers and changes in coastal habitats at decadal, annual and seasonal time scales, combined with biophysical dispersal models to demonstrate ecosystem responses against socio economic stressors.

Tinanshuo Xu, PhD student Stockholm University


I study the dynamic and functionality of symbiotic gut bacteria in zooplankton. Bacterioplankton and zooplankton are two key groups of organisms in aquatic systems, shaping the functionality of aquatic ecosystems and biogeochemical cycles. Bacterial symbionts in guts of macrofauna perform important functions related to the physiological status of the host, and contribute to the dynamics of host communities. Bacteria-zooplankton associations are assumed to have critical ecological functions. However, the mechanisms affecting bacteria and zooplankton interactions are not well described. My PhD program aims to use molecular technics to describe the composition and dynamics of gut symbiotic bacteria and their coupling with zooplankton hosts, using the Baltic Sea as a model ecosystem.

I am a PhD student in Marine Biology. My project aims to give a better description of the plankton-fish link using novel molecular tools. Planktivorous fish are key components of the pelagic food web as they support upper trophic levels, such as commercially important fish, and indirectly control algal growth by feeding on zooplankton. Although understanding the interactions between plankton and fish is crucial for the development of ecosystem-based management strategies, the full spectrum of planktivorous fish prey is rarely considered, mostly due to limitations of the methods. In this project, DNA metabarcoding on low levels of dietary DNA (dDNA) and modeling will be used to investigate the full prey spectrum of planktivorous fish. The outcome of the project will provide a better understanding on the plankton-fish interactions and help predict the variation of energy flow from primary producer to fish under different scenarios, such as climate warming, eutrophicationand fisheries.
