Although parasitism is one of the most prevalent interactions in nature, studies of aquatic food webs rarely include parasites. Syndiniales (Dinophyceae, Alveolata) is a diverse parasitic group of dinoflagellates, common in all marine environments, and are described as dominant components of pelagic ecosystems. However, their temporal dynamics, prevalence, and host-specificity are poorly known. Using DNA … More New article on evidence of host-parasite interactions in zooplankton

This study is published in Molecular Ecology and shows for the first time the natural diet of zooplankton under temporal variation of food resources. Knowledge of zooplankton in situ diet is critical for accurate assessment of marine ecosystem function and structure, but due to methodological constraints, there is still a limited understanding of ecological networks … More Reconstructing plankton food web interactions with DNA metabarcoding

To predict effects of global change on zooplankton populations, it is important to understand how present species adapt to temperature and how they respond to stressors interacting with temperature. Here, we ask if the calanoid copepod Eurytemora affinis from the Baltic Sea can adapt to future climate warming. Populations were sampled at sites with different temperatures. Full … More New study shows that some populations of the copepod Eurytemora affinis can adapt to a future warmer Baltic Sea

We used dynamic factor analysis to study if there are common patterns of interannual variation that are shared (“common trends”) among summer phytoplankton total and class-level biomass time series observed across Baltic Sea latitudinal gradients in salinity and temperature. We evaluated alternative hypotheses regarding common trends among summer phytoplankton biomass: Baltic Sea-wide common trends; common … More New study shows limited evidence for common interannual trends in Baltic Sea summer phytoplankton biomass

A new publication shows that spring phytoplankton blooms occur 1-2 weeks earlier over the last 20 years in the central Baltic Sea. Warmer temperature advance timing of diatom and dinoflagellates, the two dominant taxonomic groups of the spring bloom, and decrease bloom magnitude. Bloom timing of the entire species composition was, however, buffered by a … More Shifting spring phytoplankton blooms in the Baltic Sea

We started a new MASMA project on fish larvae distribution in coastal East Africa in collaboration with the Kenya Marine and Fisheries Research Institute, Mombasa, Kenya, and the Institute of Marine Sciences, Zanzibar, Tanzania. This project aims to understand to what extent food-provisioning services in the form of fish larval production are threatened by habitat … More New MASMA Project: LARVAL FISH PRODUCTION AND DISPERSAL IN CRITICAL HABITATS OF COASTAL EAST AFRICA

We have an open PhD position in ‘Ecological network modelling of plankton food webs’ in our group. This is a 4-yr position with the goal to use existing environmental, species and sequencing data gathered in extensive monitoring and metabarcoding studies to describe patterns of biotic interaction strength and explore their implications for food web dynamics. … More Open PhD position in Marine Biology focusing on ecological network modelling

To understand the effects of predicted warming and changing salinity of marine ecosystems, it is important to have a good knowledge of their capacity to adapt to environmental changes. In this study we investigated how different populations of the copepod Eurytemora affinis from the Baltic Sea respond to varying temperatures and salinity conditions. We collected … More New paper on: Life-history responses to changing temperature and salinity of the Baltic Sea copepod Eurytemora affinis by Konrad Karlsson et al.

We started an exciting collaboration with José Marin at the Charles Darwin Foundation and Rafael Bermudez at Universidad San Francisco de Quito (USFQ) on research in the Galapagos Archipelago and visited the islands in January. The Galapagos are famous for their large number of endemic species with beautiful and interesting ecosystems. Planktonic organisms are however … More New project on the Galapagos Archipelago
