About Kerstin Johannesson

Professor in Marine Ecology and Director of Tjärnö Marine Laboratory.


Research Interests

As a researcher, I am interested in understanding the mechanisms of evolution generating new biodiversity, within species forming ecotypes and locally adapted populations and the mechanisms forming new species. These mechanisms include: population structure, natural selection, genetic drift,  gene flow and recombination and others.

These same mechanisms are also at work under environmental change and suggests that genetic diversity is a key element that needs protection along with species diversity.

In my studies I use marine organisms, such as gastropods of the genus Littorina (periwinkles) and brown seaweed of the genus Fucus (wrack), to study mechanisms of evolution. This includes both ecological mechanisms and genetic mechanisms.

Evolution and speciation in marine snails (Littorina)

1980- ongoing
My never-ending graduate student project that focus on the behavioural an evolutionary ecology, genetics and genomics of Littorina saxatilis and L. fabalis. We now have draft genomes of both species and together with Roger Butlin, Anja Westram, Rui Faria and Marina Panova and many others we are exploring the molecular mechanisms of divergence and ecotype formation.


Funding: Swedish Research Council VR (since 1987).

 

 

Evolution and conservation genetics of brown seaweed (Fucus)

2004-ongoing
This project was initiated to address the taxonomic status of a dwarph morph of Baltic Sea Fucus vesiculosus. When we applied genetic analyses, the dwarf morph unveiled a separate species, Fucus radicans. This species is endemic to the Baltic Sea and a major perennial seaweed in the north. We have also discovered that a unique trait of Baltic Sea fucoids is cloning, which is important knowledge in conservation and management of these species. I run this project together with Ricardo Pereyra and in collaboration with many others.


Funding: Swedish Research Council, Formas (2004-2011), BONUS-BaltGene (2009-2011), BONUS-Bambi (2014-2017), MARFOR (2017-2019).

 

Earlier Research Activities

BaltGene – Baltic Sea Genetic Biodiversity

2009-2011 (KJ coordinator, 20 researchers involved from 7 universities in 4 countries)
A multidisciplinary research project under the BONUS programme with focus on describing the population genetic structure of 8-10 Baltic Sea species. The program produced more than 40 scientific publications (all listed on the web page), 5 PhD thesis, and a web-tool providing guidelines for end users.
Funding: BONUS EEIG, 1.6 m€

MARBIPP - Marine Biodiversity, Patterns and Processes

2001-2006 (KJ coordinator, 35 Swedish researchers involved from 5 research organizations)
This was a broad research program with the objective of producing new knowledge and end-user friendly advices in the area of marine coastal biodiversity. The program dealt mainly with five coastal biotopes; seagrass beds, macroalgal forests, shallow sandy bottoms, mussel beds and deep coral reefs. The program produced more than 80 scientific publications, 9 PhD thesis (see www.marbipp.tmbl.gu.se) and web-tool guidelines for end-users (see www.marbipp.se).
Funding: Swedish Environmental Protection Agency, 35 million SEK 

 

EUMAR - European Marine Genetic Biodiversity

2001-2004 (KJ coordinator, 30 EU researchers involved from 5 countries)
Research program addressing conservation genetics of marine invertebrate species of coastal Europe, with special emphasis on mechanisms that generated genetic structures in macro algae, seagrasses, snails, limpets, and barnacles. Collaborating partners from Italy (2 partners), Spain (1 partner), Belgium (1 partner), UK (2 partners). This program produced about 70 scientific publications and 5 PhD theses.
Funding: 5th FP European Union, 1.8 million EURO.
