"Coral reefs… are fragile structures living within a narrow range of temperature, clarity, salinity and chemistry. Even a slight increase in ocean temperature, or increased CO2… can cause stresses such as bleaching… These stresses slow the rate of growth of the corrals… With some 60 percent...

Management actions that address local-scale stressors on coral reefs can rapidly improve water quality and reef ecosystem condition. In response to reef managers who need actionable thresholds for coastal runoff and dredging, we conducted a systematic review and meta-analysis of experimental studies tha...
While the effects of OA are ubiquitous, they are of particular concern for calcifying organisms such as scleractinian corals, which use carbonate ions to build their skeleton (Hofmann et al.2010). This potential for OA to reduce calcification in corals has identified coral reefs as one of the ...
The coral colonies used were kept in captivity for several years, providing information on their thermal and salinity history. Twenty replicate fragments were cut from each coral species' colony, weighed and glued to the top of a numbered expansion anchor and then acclimated to the experimental ...
The production of larvae is an important part of sea cucumber aquaculture, and the extreme salinity can adversely affect the growth and development of the larval sea cucumbers, however, most of the studies about salinity focus on adult sea cucumbers, and information on the larvae is still ...
Salinity was 35.00 ± 0.01 in each treatment. Growth experiment 1: ambient seawater, mean pH 8.1. Relative growth rates of blades were on aver- age 47% greater in the fluctuating pH treatment than in all other treatments (Table 2, Fig. 1a). Net photosynthetic rates ...
based on sex-specific seasonal anorexia induced by reproductive activities. Turtle-headed sea snakes (Emydocephalus annulatus) on coral reefs in the New Caledonian Lagoon feed entirely on the eggs of demersal-spawning fishes. DNA sequence data (cytochrome b gene) on eggs that we palpated from ...
For corals, thermal stress, changes in salinity, high doses of ultraviolet radiation or a combination of these factors can all lead to increased activity of enzymatic antioxidants (Downs et al., 2002; Levy et al., 2006; Shick et al., 1995). However, in the present study the exposure to...
However, directly translating these results to field situations should be done with caution, as conditions in the field are far less consistent and may be complicated by additional factors that can affect the reproductive and recruitment process (i.e., waves, pH, salinity30,55–57). Since ...
