This 2025 GAME project on artificial light pollution tests its influence on marine epiphytes simultaneously and worldwide.
This year’s GAME Team are Linus Holmlund (from Åbo Akademi University, Finland)
& Pauline Wasle (from Faculdade de Ciências e Tecnologia, Portugal)
GAME 2025 at Husö Biologiska Station will Explore the Impact of Artificial Light At Night (ALAN) on Fucus vesiculosus and its interaction with its epiphytic algae: GAME 2025 will focus on the competition between epiphytes and macroalgae. If nocturnal artificial light favours epiphytes, this could lead to a shift in the competitive relationship towards a stronger growth of epiphytes, which in turn could lead to a decline in the horizontal and vertical distribution of macroalgae. By this, artificial light at night could lead to a restructuring of marine benthic habitats. The experiments will be carried out in open water, as a natural pool of spores and cells must be available for the epiphytes to colonise. Appropriate locations by the sea near the GAME partner institutes have already been identified in previous projects. At these sites, it will be possible to permanently install and operate artificial light sources (LED) and place a submersed setup to which macroalgal thalli or thallus sections can be attached.
