Research and expertise

 

Research:

- The role of phytoplankton in nutrient cycling and carbon sequestration in coastal marine ecosystems

- Ecology of Harmful algal blooms - HABs

- Understanding the functional ecology of phytoplankton species based on their functional traits

- Research on the diversity of phytoplankton viruses, particularly diatom viruses, and the impact of viral infections on biogeochemical cycling

- Research on the genetic traits of ecologically important species (including HABs) and the development of new methods in environmental diagnostics

- Maintenance of long-term biological and chemical datasets

- Investigation of long-term changes and trends in plankton communities using statistical analyses and modelling

- Development of methods for assessing the environmental status of the sea based on phytoplankton

 

Ekspertise:

 

- Integrative taxonomy of phytoplankton (light and electron microscopy, cultivation and phylogenetic barcoding of individual strains, metabarcoding of phytoplankton communities)

- Determination of the structure and function of phytoplankton communities using cultivation-independent and next-generation sequencing methods, as well as advanced bioinformatics and computational biology tools

- Cultivation, taxonomic identification and investigation of the physiology and biochemistry of selected microalgal strains from the MBP culture collection

- Classical virology and metagenomic analysis of viral communities

- Measurement of primary production using radioactively labelled isotope (14C)

- Chemotaxonomy (HPLC pigment analysis)

- Scanning electron microscopy – SEM (biological samples)

Other activities

 

Education and outreach:

 

Members of the group hold teaching positions or are actively involved in teaching activities at:

- University of Primorska, Faculty of Mathematics, Natural Sciences and Information Technologies, Faculty of Education

- University of Ljubljana: Interdisciplinary Doctoral Study Programme in Environmental Protection

- Jožef Stefan International Postgraduate School

 

We are committed to human resource development, not only through the programme for young researchers, but also as tutors of domestic and international students during compulsory internships and as supervisors of bachelor's, master's, and doctoral theses. Through regular outreach activities (e.g. open-door events, researcher nights) and other dissemination strategies, we contribute to society’s ocean literacy.
