What are the impacts of sediment on coral?
Best insight from top research papers
Sediment has various impacts on coral reefs. It can adversely affect corals by causing tissue mortality, reduced growth rates, limited settlement rates, and bleaching . Sediment can smother, abrade, shade, and inhibit coral recruitment . The effects of sediment on corals can be influenced by factors such as sediment grain size and type, as well as coral species and life-history stage . Sediment stress can lead to changes in coral physiology at the molecular level, including the upregulation of genes related to energy metabolism and immune response . Different coral morphologies can also influence their susceptibility to sediment stress, with branching corals showing a larger transcriptomic response compared to massive corals . Overall, sedimentation poses a significant threat to coral health and reef ecosystems, highlighting the need for effective management strategies to mitigate its impacts.

What are the effects of suspended sediment on fish?4 answersSuspended sediment can have various effects on fish. Increased suspended sediment concentrations (SSC) can cause fish eggs to sink out of their optimal hatching conditions, leading to decreased reproductive success. High SSC resulting from dam removal or sediment flushing processes can have acute impacts on aquatic organisms, including fish. Fish behavior, such as aquatic surface respiration and mortality, can be affected by high SSC levels. Copepods, a type of zooplankton, show increased motility in the presence of sediment, potentially trying to transport themselves out of sediment-affected areas. The effects of chronic turbidity created by fine suspended sediment on fish health and growth vary depending on the species and their natural habitat. Different fish species have different thresholds of sensitivity to suspended matter, with some species being more tolerant than others.
What is the short term oil spill impact on corals?5 answersShort-term oil spill impacts on corals include substantial declines in live cover and diversity, changes in community structure, and increased injuries and growth reduction in some species. The effects can be detected up to 4 years after the spill, with branching corals appearing to suffer more. The decline in coral cover and diversity is most pronounced in Acropora palmata, a large branching coral. Other benthic taxa are less affected by oil spills. Additionally, the spill can lead to changes in the carbon source for coral calcification, resulting in lower δ13C values in coral skeletal records. However, the long-term chronic impact of oil spills on corals is not evident, as other stressors and factors contribute to reef degradation over time.
What is environmental impact for coastal reclamation ?5 answersCoastal reclamation has significant environmental impacts. It can lead to the loss and degradation of coastal and marine resources, disruption of the natural balance of marine environments, and alteration of coastal profiles. Reclamation projects can result in the degradation and loss of ecosystem services and marine habitat, urban sprawl, and increased flood risk. Additionally, the construction of seawalls and the spread of invasive plant species can contribute to the accumulation of trace metals in coastal wetlands, posing a risk to the environment and ecosystems. Coastal reclamation can also affect water quality and coast conditions, although the long-term trends may vary. Furthermore, the conversion of wetlands due to reclamation can impact soil microbial communities, which in turn affects carbon and nitrogen sinks in ecosystems. Overall, coastal reclamation has wide-ranging and potentially detrimental environmental consequences.
What volume of sediment is considered as beneficial in the environment?5 answersThe volume of sediment considered beneficial in the environment is not specified in the abstracts provided.
What are the negative impacts of sediment transport?3 answersSediment transport can have negative impacts on the environment. Sediments transported by waves and currents can reduce ambient light and change the character of the aquatic environment. In river systems, sediment transport imbalances can lead to problems such as channel change, riverbed degradation, reservoir sedimentation, and loss of instream structures. Excessive sediment content can block pipelines and halt construction, while low sediment content reduces efficiency. Ship-generated waves and accelerated currents can also influence sediment transport, causing resuspension and acceleration effects. These impacts can affect flood protection, river engineering, hydropower generation, and the ecological status of running waters.
What are the effects of sediment on fish ponds?3 answersSediment in fish ponds can have various effects on the aquatic environment. Fine sediment and suspended solids from fish ponds can increase turbidity and deposition rates in receiving streams, potentially impacting the development of endangered freshwater pearl mussels. Sediment and nutrient accumulation in tilapia ponds can be significant, with the accumulated sediment containing nutrients that can be used as fertilizer in land-based agriculture. Road runoff, which includes sediment, can affect fish health and transfer polycyclic aromatic hydrocarbons (PAHs) to aquatic organisms. Organic matter accumulation in fish ponds, including dead phytoplankton, fish faeces, and uneaten feed, can lead to nitrogen dynamics and mineralization processes in the sediment. Additionally, sediment in tilapia ponds can contribute to the accumulation of off-flavor compounds, such as geosmin and 2-methylisoborneol, which can affect fish quality.
