About me

I’ve a background in environmental science (B.S.), biology: limnology (M.S.), and ecology: marine microbiology (doctorate). I work in the research group of Francisco Nascimento. My current research focuses on Baltic Sea sediments, with a strong focus on molecular biology methods and data analysis of high-throughput DNA/RNA sequencing data.

Research

In more detail, the aim is to investigate the diversity and metabolic functions of benthic prokaryotes and meiofauna (animals < 1 mm). The aim of the project is also to link prokaryotic-meiofauna interactions in the sediment to benthic-pelagic exchange of greenhouse gases, as well as adaptation to future climate change scenarios.

    Coastal benthic biodiversity is under increased pressure from climate change, eutrophication,hypoxia, and changes in salinity due to increase in river runoff. TheBaltic Sea is a large brackish system characterized by steep environmental gradientsthat experiences all of the mentioned stressors. As such it provides an ideal modelsystem for studying the impact of on‐going and future climate change on biodiversityand function of benthic ecosystems. Meiofauna (animals < 1 mm) are abundant insediment and are still largely unexplored even though they are known to regulateorganic matter degradation and nutrient cycling. In this study, benthic meiofaunalcommunity structure was analysed along a salinity gradient in the Baltic Sea properusing high‐throughput sequencing. Our results demonstrate that areas with highersalinity have a higher biodiversity, and salinity is probably the main driver influencingmeiofauna diversity and community composition. Furthermore, in the more diverseand saline environments a larger amount of nematode genera classified as predatorsprevailed, and meiofauna‐macrofauna associations were more prominent. Thesefindings show that in the Baltic Sea, a decrease in salinity resulting from acceleratedclimate change will probably lead to decreased benthic biodiversity, and cause profoundchanges in benthic communities, with potential consequences for ecosystemstability, functions and services.
