“…and expressed in lg l -1 . Chl a was used as a more reliable measure of eutrophication in oligotrophic waters (Bell 1992, Jameson andKelty 2004) than inorganic nutrients that are incorporated immediately by the phytoplankton community (Furnas et al 2005). Chl a was extracted from the filter with 90% acetone following the procedure described below for the tissue chl a.…”

“…Increased particle loads may also enhance coral mucus production in response to particles settling on the coral surface (Stafford-Smith 1993;Riegl and Branch 1995;Brown and Bythell 2005). In spite of significant inputs of riverine nutrients, the associated changes in inorganic nutrient concentrations are often insignificant due to their rapid incorporation by nutrientstarved plankton in reefs (Furnas et al 2005).…”

Nutritional status and metabolism of the coral Stylophora subseriata along a eutrophication gradient in Spermonde Archipelago (Indonesia)

et al. 2011

Coral responses to degrading water quality are highly variable between species and depend on their trophic plasticity, acclimatization potential, and stress resistance. To assess the nutritional status and metabolism of the common scleractinian coral, Stylophora subseriata, in situ experiments were carried along a eutrophication gradient in Spermonde Archipelago, Indonesia. Coral fragments were incubated in light and dark chambers to measure photosynthesis, respiration, and calcification in a number of shallow reefs along the gradient. Chlorophyll a (chl a), protein content, maximum quantum yield (F v / F m ), and effective quantum yield (U PS II) were measured on the zooxanthellae, in addition to host tissue protein content and biomass. Photosynthetic rates were 2.5-fold higher near-shore than mid-shelf due to higher areal zooxanthellae and chl a concentrations and a higher photochemical efficiency (U PS II). A 2-and 3-fold increase in areal host tissue protein and biomass was found, indicating a higher nutritional supply in coastal waters. Dark respiration, however, showed no corresponding changes. There was a weak correlation between calcification and photosynthesis (Pearson r = 0.386) and a lack of metabolic stress, as indicated by constant respiration and F v /F m and the ''clean'' and healthy appearance of the colonies in spite of high turbidity in near-shore waters. The latter suggests that part of the energetic gains through increased auto-and heterotrophy were spent on metabolic expenditures, e.g., mucus production. While coastal pollution is always deleterious to the reef ecosystem as a whole, our results show that the effect on corals may not always be negative. Thus, S. subseriata may be one of the few examples of corals actually profiting from land-based sources of pollution.

“…Chlorophyll-a may reflect the influence of nutrients delivered from coastal runoff in nonupwelling regions (Furnas et al, 2005). Therefore, differences in chlorophyll-a concentrations between sites were compared using monthly-averaged satellite-derived data spanning October 1997 to October 2007, obtained from the Sea-viewing Wide Fieldof-view Sensor (Sea-WiFS) from NOAA Coastwatch (O'Reilly et al, 1998).…”

The Mesoamerican Reef, the second-largest barrier reef in the world, is located in the western Caribbean Sea off the coasts of Mexico, Belize, Guatemala, and Honduras. Particularly in the south, the surrounding watersheds are steep and the climate is extremely wet. With development and agricultural expansion, the potential for negative impacts to the reef from land-based runoff becomes high. We constructed annually resolved century-scale records of metal/calcium ratios in coral skeletons collected from four sites experiencing a gradient of land-based runoff. Our proxy data indicate that runoff onto the reef has increased relatively steadily over time at all sites, consistent with land use trends from historical records. Sediment supply to the reef is greater in the south, and these more exposed reefs will probably benefit most immediately from management that targets runoff reduction. However, because runoff at all sites is steadily increasing, even distal sites will benefit from watershed management.

“…22 No. 2 December 2016: The recent studies in the GBR mostly covered oceanography (Eric W olanski, 1994), primary production and energy scheme (Furnas et al, 2005), habitats and biological assemblages (Fabricius et al, 2005;Hurrey et al, 2013;Kramer et al, 2014), coral reef matters (Graham et al, 2014;Uthicke et al, 2014) and climate change impact (Fidelman et al, 2013;Sutton & Tobin, 2011;Zeppel, 2011). However, the impact of climate change to biological assemblages is limited on the multiple effects on food web due to highly uncertainty on the response of individual marine creatures.…”

Spatial and temporal variations in the fish and decapod communities were investigated at three stations in Cleveland Bay along with other zooplankton and phytoplankton communities. The linkage between biological assemblages and physical properties of the ocean was explained to develop better understanding of population dynamic of planktonic communities. Biological and physical properties data were gathered in 3 stations by 6 different trips. The results show that there is a significant association between daytime and tidal period to the abundance of planktonic communities (P < 0.05). Spatial distribution of fish and decapod communities are likely explained by "predator pit" and "match/mismatch" concepts to increase the survival probability along with physical properties of the ocean.
