Euendolithic Infestation of Mussel Shells Indirectly Improves the Thermal Buffering Offered by Mussel Beds to Associated Molluscs, but One Size Does Not Fit All

چکیده
Mussel beds form important intertidal matrices that provide thermal buffering to associated invertebrate communities, especially under stressful environmental conditions. shells are often colonized by photoautotrophic euendoliths, which have indirect conditional beneficial thermoregulatory effects on both solitary and aggregated mussels increasing the albedo of shell. We investigated whether euendolithic infestation artificial mussel (Perna perna) influences body temperatures four mollusc species during simulated periods emersion, using shell temperature obtained via non-invasive infrared thermography as a proxy. Shell limpet Scutellastra granularis chiton Acanthochitona garnoti were higher in non-infested than infested low tides high solar irradiance wind speeds. However, this was not case for Helcion pectunculus or top Oxystele antoni. Morphological differences shape colour could, part, explain contrast between species. Our results indicated endolith-induced improvements humidity could benefit molluscs. The offered effective only if organism heat stress. With global climate change, effect communities with may mitigate local extinction events triggered marine heatwaves.
