Presentation Transcript

  1. Eco-physiological adaptation of model polychaete species to climate change and laboratory rearing protocols Alexia Massa Gallucci Scientific Coordinator: Maria Cristina Gambi Laboratory of Functional and Evolutionary Ecology, StazioneZoologica Anton Dohrn, Napoli research team at Villa Dohrn Ischia

  2. Seawater pH Extreme Low CO2 vents and acidified areas off Ischia Low CastelloAragonese, Ischia Ambient North side 7.0 South side pH gradient 8.1

  3. Model Polychaete Species Amphiglenamediterranea(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 Syllisprolifera(Krohn,1852)Syllidae Size: 5-25 mm Ecology: littoral vegetated rocky reef, and seagrassmeadows Trophic habit: mesograzer Reproductive biology:iteroparous, sexual stolons Geographic distribution: Mediterranean Sea and North Atlantic Ocean

  4. Project objective: Rearing Protocols • Set-up of standardized rearing protocols to obtain a multi-cohort-population of model species

  5. 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
