Model Polychaete Species
Amphiglena mediterranea (Leydig,1851) Sabellidae
Size: 4-5 mm
Ecology: littoral vegetated rocky reef, and seagrass meadows
Trophic habits: filter feeder
Reproductive biology: iteroparous, brooder inside the tube
Geographic distribution: Mediterranean Sea and
North Atlantic Ocean
Syllis prolifera (Krohn,1852) Syllidae
Size: 5-25 mm
Ecology: littoral vegetated rocky reef, and seagrass meadows
Trophic habit: mesograzer
Reproductive biology: iteroparous, sexual stolons
Geographic distribution: Mediterranean Sea and
North Atlantic Ocean
Project objective: Rearing Protocols
•
Set-up of standardized rearing
protocols to obtain a multi-cohortpopulation 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 labreared population: biometric data, tissue
regeneration and reproductive output
