Model Polychaete Species
Size: 4-5 mm Ecology: littoral vegetated rocky reef, and seagrass meadowsTrophic habits: filter feeder Reproductive biology: iteroparous, brooder inside the tubeGeographic distribution: Mediterranean Sea and North Atlantic Ocean
Size: 5-25 mmEcology: littoral vegetated rocky reef, and seagrass meadowsTrophic habit: mesograzer Reproductive biology: iteroparous, sexual stolonsGeographic distribution: Mediterranean Sea and North Atlantic Ocean
Project objective: Rearing Protocols
• Set-up of standardized rearing
protocols to obtain a multi-cohort-
population of model species
Project objective: Eco-physiological adaptation to Climate Change
Study biological and eco-physiological adaptation
to climate change of model species:
• In situ reciprocal transplant experiments and measure of metabolic rates and biomarkers
• Test of pH and temperature variation on lab-reared population: biometric data, tissue regeneration and reproductive output
