Italian still life paintings as a resource for reconstructing past Mediterranean aquatic biodiversity

Our study explores the use of Italian still-life paintings from the Early Modern Period (16^th-18^th centuries) as historical records of past Mediterranean aquatic biodiversity. Following an environmental history approach, we analysed taxonomic composition in paintings, first examining geographic and temporal variations shaped by technical and socio-cultural influences. After consideration of these factors, we performed a detailed ecological interpretation of depicted taxa. Our findings reveal a shift from freshwater to marine resource use, driven by evolving fishing practices and technological advances. Socio-cultural elements, such as culinary traditions, religion and aesthetics also strongly shaped species representation. We discuss ecological interpretation of the representation of vulnerable and emblematic Mediterranean species in light of climate change, overexploitation and species biogeography. Our research highlights the powerful role of paintings in reconstructing past exploited ecosystems, offering a unique perspective for informing contemporary conservation efforts.
