Physical and cellular impact of environmentally relevant microplastic exposure on thermally challenged Pocillopora damicornis (Cnidaria, Scleractinia)

Microplastic pollution is an increasing threat to coral reefs, which are already strongly challenged by climate change-related heat stress. Although it known that scleractinian corals can ingest microplastic, little about their egestion and how microplastic exposure may impair at physiological cellular levels. In addition, the effects of current environmental concentration have been investigated date, particularly in impacted this study, combined these threats on Pocillopora damicornis were from a physical perspective. Colonies exposed three concentrations polyethylene beads (no beads: [No MP], 1 mg/L: [Low MP]; 10 [High MP]), two different temperatures (25 °C 30 °C) for 72 h. No visual signs stress corals, such as abnormal mucus production polyp extroflection, recorded. At adhered colonies ingested but also egested. Moreover, thermally stressed showed lower adhesion higher beads. Coral bleaching was observed with increase temperature bead concentration, indicated general decrease chlorophyll Symbiodiniaceae density. An lipid peroxidation measured MP] up-regulation response gene hsp70 due synergistic interaction both stressors. Overall, our findings still represents main P. damicornis, while effect microplastics health physiology be minor, especially control temperature. However, could exacerbate thermal homeostasis, even MP]. While reducing ocean warming critical preserving effective management emerging like equally essential.

Published: June 24, 2024

The causes of the physiological effects microplastic pollution, potentially harming reef-building corals, are unclear. Reasons might include increased energy demands for handling particles and immune reactions. This study is among first assessing long-term exposure on coral physiology at realistic concentrations (200 polyethylene L

Exploring Microplastic Interactions with Reef-Building Corals Across Flow Conditions

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 12, 2024

Microplastics are increasing in marine environments worldwide, but their fate is not fully understood. Reef-building corals suggested to serve as sinks for microplastics via active removal through ingestion and passive by adhesion. However, it unknown which type of plastics more likely be ingested or adhered whether water flow coral morphology affects these processes. We exposed the corals, Leptoseris sp., Montipora capitata, digitata, Pocillopora acuta weathered polyester fibers, acrylic polystyrene fragments under three unidirectional regimes (2.6, 5.0 7.5 cm s^{− 1}). Adhesion rates were 3.9 times higher than fibers dominant both Flow significantly affected adhesion ingestion. Species was a significant factor adhesion, we did find correlation morphological traits either process. Moreover, on M. observed skeleton live tissue, suggesting that capitata actively removes from its surface non-living sections reefs may also an important sink microplastic pollution. Our data revealed processes influence interactions complex appear species-specific influenced feeding strategies other characteristics corals. highlight potential structures sinks.
