Reef-Building Corals Do Not Develop Adaptive Mechanisms to Better Cope With Microplastics

نویسندگان

چکیده

Microplastics are omnipresent in the oceans and threaten marine animals through physical contact or ingestion. Short-term studies have already shown that reef-building stony corals respond differently to microplastics than natural food. However, it remains unknown whether exhibit acclimation mechanisms combat effects of microplastic exposure. Specifically, long-term on feeding defense behavior remain unexplored. Therefore, goal this study was infer potential corals. For this, four species ( Acropora muricata , Porites lutea Pocillopora verrucosa Heliopora coerulea ) were exposed a experiment for 15 months. Subsequently, coral rates food Artemia sp. cysts), discrimination, reactions both assessed 24 h pulse exposure experiment. The results showed corals’ did not decrease after microplastics. Similarly, discrimination (i.e., ratio food) differ Moreover, no changes mucus production extrusion mesenterial filaments) against These findings suggest symbiotic, do develop adapt Thus, pollution might constitute constant stressor organisms, likely leading sustained energy expenditures impaired health.

Multilocus Adaptation Associated with Heat Resistance in Reef-Building Corals

The evolution of tolerance to future climate change depends on the standing stock of genetic variation for resistance to climate-related impacts, but genes contributing to climate tolerance in wild populations are poorly described in number and effect. Physiology and gene expression patterns have shown that corals living in naturally high-temperature microclimates are more resistant to bleachin...

Environmental Symbiont Acquisition May Not Be the Solution to Warming Seas for Reef-Building Corals

BACKGROUND Coral reefs worldwide are in decline. Much of the mortality can be attributed to coral bleaching (loss of the coral's intracellular photosynthetic algal symbiont) associated with global warming. How corals will respond to increasing oceanic temperatures has been an area of extensive study and debate. Recovery after a bleaching event is dependent on regaining symbionts, but the source...

Application of 1H-NMR Metabolomic Profiling for Reef-Building Corals

In light of global reef decline new methods to accurately, cheaply, and quickly evaluate coral metabolic states are needed to assess reef health. Metabolomic profiling can describe the response of individuals to disturbance (i.e., shifts in environmental conditions) across biological models and is a powerful approach for characterizing and comparing coral metabolism. For the first time, we asse...
