“…The early life history stages of coral have been shown to be extremely sensitive to changes in water quality (Ward and Harrison 1997;Negri et al 2005;Markey et al 2007), partic- ularly fertilisation Reichelt-Brushett and Harrison 2005). The Wnding that environmentally realistic changes in suspended sediment, salinity and dissolved inorganic nutrients can have a negative impact on fertilisation, and to a lesser extent on development, is clearly a reason for concern.…”

Exposure of coral reefs to river plumes carrying increasing loads of nutrients and sediments is a pressing issue for coral reefs around the world including the Great Barrier Reef (GBR). Laboratory experiments were conducted to investigate the eVects of changes in inorganic nutrients (nitrate, ammonium and phosphate), salinity and various types of suspended sediments in isolation and in combination on rates of fertilisation and early embryonic development of the scleractinian coral Acropora millepora. Dose-response experiments showed that fertilisation declined signiWcantly with increasing sediments and decreasing salinity, while inorganic nutrients at up to 20 M nitrate or ammonium and 4 M phosphate had no signiWcant eVect on fertilisation. Suspended sediments of ¸100 mg l ¡1 and salinity of 30 ppt reduced fertilisation by >50%. Developmental abnormality occurred in 100% of embryos at 30 ppt salinity, and no fertilisation occurred at ·28 ppt. Another experiment tested interactions between sediment, salinity and nutrients and showed that fertilisation was signiWcantly reduced when nutrients and low concentrations of sediments co-occurred, although both on their own had no eVect on fertilisation rates. Similarly, while slightly reduced salinity on its own had no eVect, fertilisation was reduced when it coincided with elevated levels of sediments or nutrients. Both these interactions were synergistic. A third experiment showed that sediments with diVerent geophysical and nutrient properties had diVerential eVects on fertilisation, possibly related to sediment and nutrient properties. The Wndings highlight the complex nature of the eVects of changing water quality on coral health, particularly stressing the signiWcance of water quality during coral spawning time.

“…The coral Platygyra daedalea was relatively insensitive to nickel; the 5-h fertilisation success was inhibited by 50% (EC50) at 1420 µg Ni -1 L (Reichelt-Brushett and Hudspith 2016; Table 6). Reichelt-Brushett and Harrison (2005) also assessed the toxicity of nickel on fertilisation success (5 h exposure) to a different species of coral, Goniastrea aspera. In this study, toxicity estimates were not provided and nickel concentrations in test solutions were not measured, however fertilisation success was inhibited by 60% at 2000 µg Ni L -1 .…”

“…Table 6), based on chronic 5-h fertilisation success. In the study by Reichelt-Brushett and Harrison (2005) with the coral G. aspera, nickel concentrations in test solutions were not measured and toxicity estimates were not provided, so this data failed the quality assurance assessment. In addition, this test was done twice across two years and significantly different results were obtained.…”

. (2016). A review of nickel toxicity to marine and estuarine tropical biota with particular reference to the South East Asian and Melanesian region. Environmental Pollution, 218 1308Pollution, 218 -1323 A review of nickel toxicity to marine and estuarine tropical biota with particular reference to the South East Asian and Melanesian region AbstractThe South East Asian Melanesian (SEAM) region contains the world's largest deposits of nickel lateritic ores. Environmental impacts may occur if mining operations are not adequately managed. Effects data for tropical ecosystems are required to assess risks of contaminant exposure and to derive water quality guidelines (WQG) to manage these risks. Currently, risk assessment tools and WQGs for the tropics are limited due to the sparse research on how contaminants impact tropical biota. As part of a larger project to develop appropriate risk assessment tools to ensure sustainable nickel production in SEAM, nickel effects data were required. The aim of this review was to compile data on the effects of nickel on tropical marine, estuarine, pelagic and benthic species, with a particular focus on SEAM. There were limited high quality chronic nickel toxicity data for tropical marine species, and even fewer for those relevant to SEAM. Of the data available, the most sensitive SEAM species to nickel were a sea urchin, copepod and anemone. There is a significant lack of high quality chronic data for several ecologically important taxonomic groups including cnidarians, molluscs, crustaceans, echinoderms, macroalgae and fish. No high quality chronic nickel toxicity data were available for estuarine waters or marine and estuarine sediments. The very sparse toxicity data for tropical species limits our ability to conduct robust ecological risk assessment and may require additional data generation or readacross from similar species in other databases (e.g. temperate) to fill data gaps. Recommendations on testing priorities to fill these data gaps are presented.

“…Anthropogenic activity, such as agriculture, is a possible source of Cd that enters the coastal marine ecosystem (de Boo 1990;Bennet-Chambers et al 1999). Regarding the effects on the coral species and ecosystem, a signifi cant reduction in the success of fertilization using Acropora tenuis gametes has been reported (Reichelt-Brushett and Harrison 2005). Although the Cd concentration that reduced the fertilization rate in Reichelt-Brushett and Harrison's experiment (higher than 10 μM) was much higher than the natural level, it is very important to gain an understanding of the Cd concentration level and its behavior in present coral reef areas.…”
