Researchers found that populations of small invertebrates thrive near rat-infested islands, where seabirds are scarce. In contrast, fish biomass is higher on reefs without rats, benefiting from nutrient-rich guano deposits.
A joint study by Tel Aviv University and the University of Haifa discovered that a soft coral's tentacles drive rhythmic movements through a decentralized neural pacemaker system. The system enables each tentacle to perform independent movement while achieving precise collective synchronization.
By 2100, coral reefs will be slow to recover, less complex, and dominated by fleshy algae as a result of high carbon dioxide changes in ocean chemistry. The study uses unique coral reefs in Papua New Guinea to determine the impact of ocean acidification on coral reefs.
Researchers used X-rays to investigate the impact of ocean acidification on corals' early skeleton development. They found that acidification affects the formation and structure of the coral's skeleton, with significant implications for marine ecosystems.
Researchers at the University of Technology Sydney discovered that tailored lipid supplements can significantly increase coral larvae's strength, speed, and survival rate. This innovation has major implications for reef restoration projects, which aim to improve larval supply but often face low post-settlement survival rates.
Researchers found that corals can regulate their calcifying fluid chemistry to maintain growth of their skeletons despite increasing ocean acidity. The study suggests an unexpected and hopeful signal, but more long-term data is needed to understand the implications.
Research reveals that even thermally tolerant coral species like Stylophora pistillata can experience reduced growth and increased metabolic demand under chronic elevated baseline temperatures. However, some corals can recover when waters cool in the winter, suggesting a potential for resilience.
New research demonstrates that corals naturally thriving in extreme environments can be used to boost the resilience of reef sites. Despite being transplanted to more stable conditions, these corals retained their heat tolerance and activated pathways associated with DNA repair and homeostasis.
A new study projects significant ocean acidification around Hawaiian Islands within the next three decades, posing challenges to coral reefs and other marine organisms. Researchers found varying levels of acidity across different island regions, with windward coastlines exhibiting higher novelty in future conditions.
A new technique allows scientists to inject molecules into coral tissues, revealing thyroxine's positive effect on calcification. The study raises questions about the evolution of animal physiology and how corals utilize thyroxine in their natural habitat.
University of Leicester researchers analyzed coral cores to spot the start of industrial deforestation in Malaysian rainforest and its impact on coastal ecosystems. The study found that sediment concentrations remained low before 1950, but increased after, indicating enhanced soil erosion due to deforestation.
Researchers found that coral reef communities persisted under certain conditions, contradicting most projections of their demise. The study's results suggest that effective climate change mitigation measures can help coral reefs adapt and thrive.
A new study by University of Texas at Arlington researchers found that living with symbiotic algae weakens the immune system of jellyfish, making them more vulnerable to infections. This finding has important implications for coral reef conservation and human disease prevention.
Scientists measured coral calcification rates off Hawaiian Islands at depths of 230-360 feet, finding the lowest rates ever recorded for healthy corals. This is due to the efficient use of calcification by corals like Leptoseris spp., which form thin horizontal skeletons to maximize area in low-light zones.
A new study using CRISPR/Cas9 technology has identified a critical gene, SLC4γ, required for young coral colonies to build their skeletons. This gene is unique to stony corals and may have evolved to support skeleton formation.
