A standardised experimental setup for simulating ocean warming and acidification in benthic marine invertebrates

Area of Science:

• Marine Biology
• Climate Change Science
• Ecotoxicology

Background:

• Ocean warming and acidification are significant threats to marine ecosystems, especially in the Eastern Mediterranean.
• Sessile or low-mobility marine organisms are particularly vulnerable to climate change impacts.
• Standardized experimental methods are crucial for reliable data on organismal responses to multiple climate stressors.

Purpose of the Study:

• To present a detailed and replicable experimental framework for simulating ocean warming and acidification.
• To provide a standardized laboratory approach for assessing benthic marine invertebrate responses to climate change.
• To demonstrate the framework's application through a case study.

Main Methods:

• Development of a controlled laboratory experimental setup.
• Detailed protocols for experimental design, climate scenario selection, and monitoring.
• Criteria for species selection and a validation case study from the MACCIMO project.

Main Results:

• A comprehensive and reproducible experimental framework for studying climate change effects on marine invertebrates.
• Demonstrated application of the framework in a real-world project (MACCIMO).
• Established a foundation for generating high-quality data on organismal responses to multiple stressors.

Conclusions:

• The presented framework enables standardized, high-quality research on climate change impacts on marine invertebrates.
• This approach is vital for predicting and mitigating threats to marine biodiversity.
• The MACCIMO project case study validates the framework's utility and replicability.
