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
