“…In contrast to the coral spat, a low seasonal variation was found in the fouling community structure on the tiles, despite seasonal variations in river runoff and, hence, nutrient supply (Renema and Troelstra, 2001;Sawall et al, 2012). This could mean that other factors, such as grazers or predators (including herbivorous fishes, but also invertebrates such as echinoids and gastropods) control sessile benthic communities on the tiles.…”

“…The predominant current is consistent with the throughflow in the Makassar Strait directed from N to S year around (Storm, 1989). The near-shore reefs which are subjected to the run-off of rivers north and south of the city of Makassar carrying untreated waste water and industrial pollution from the 1.5 million inhabitants along with agricultural run-off feature only low coral cover and diversity (Edinger et al, 1998;Renema and Troelstra, 2001). The near midshelf reefs are still affected by the land run-off during the wet season (November to February), but also by local waste water discharge in some of the populated islands (Edinger et al, 1998;Renema and Troelstra, 2001).…”

“…Although Spermonde is one of the best studied reef systems in Indonesia, with detailed studies on reef distribution and biodiversity (e.g., Moll, 1983;Renema and Troelstra, 2001;Cleary et al, 2005), population dynamics (e.g., Knittweis et al, 2009) and coral physiology (Sawall et al, 2011), so far nothing is known about coral recruitment, in spite of reef monitoring and management activities over many years (e.g., COREMAP).…”

a b s t r a c tCoral recruitment was assessed in highly diverse and economically important Spermonde Archipelago, a reef system subjected to land-based sources of siltation/pollution and destructive fishing, over a period of 2 years. Recruitment on settlement tiles reached up to 705 spat m À2 yr À1 and was strongest in the dry season (July-October), except off-shore, where larvae settled earlier. Pocilloporidae dominated nearshore, while a more diverse community of Acroporidae, Poritidae and others settled in the less polluted mid-shelf and off-shore reefs. Non-coral fouling community appeared to hardly influence initial coral settlement on the tiles, although, this does not necessarily infer low coral post-settlement mortality, which may be enhanced at the near-and off-shore reefs as indicated by increased abundances of potential space competitors on natural substrate. Blast fishing showed no local reduction in coral recruitment and live hard coral cover increased in oligotrophic reefs, indicating potential for coral recovery, if managed effectively.

“…The near-shore areas are affected by effluents from the Makassar harbor and the fluvial discharge by the river Jene Berang to the south and several small rivers to the north of Makassar. These rivers introduce terrigenious sediments, wastewater, and aquaculture outflows to the near-shore reefs (Renema and Troelstra 2001). A clear demise in coral diversity and cover from low impacted mid-shelf reefs to highly polluted near-shore reefs was demonstrated by Edinger et al (1998).…”

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.

Alveolinids from the Lower Indus Basin, Pakistan (Eastern Neo‐Tethys): Systematic and biostratigraphic implications

et al. 2021

The alveolinid group of larger benthic foraminifera has been vastly studied in western and central Neo-Tethys, but less well analysed in eastern Neo-Tethys. In this study, 19 Ypresian (Ilerdian-Cuisian) and Early Lutetian species of Alveolina have been identified and their biometrics, taxonomy, and biostratigraphic correlation with western and central Neo-Tethys discussed. The Taxa of Early Ypresian age (SBZ5-9) includes Alveolina vredenburgi, A. dedolia, A. subpyrenaica, A. cf. subpyrenaica, A. moussoulensis, A. aragonensis, A. decipiens, A. cylindrata, and A. ilerdensis. The Late Ypresian age (SBZ10-12) taxa includes A. ruetimeyeri A. oblonga, A. haymanensis, A. lehneri, A. cosinensis cosigena, A. aff. frumentiformis, A sp. aff. A. azzarolii, and A. elliptica. The Early Lutetian age (SBZ13) taxa include A. stercusmuris and A. keili. The identified species have a close affinity to those reported from other areas of the Tethyan realm.However, some of these Alveolina species are considered to have stratigraphic ranges longer than formerly reported. The first appearance of A. ilerdensis (SBZ8-10) is recorded earlier in SBZ7. The first appearance of A. ruetimeyeri (SBZ10-11) is recorded earlier in SBZ-9. The study provides more evidence for understanding the evolution of the Alveolina species and their biostratigraphic distribution in the eastern Tethyan realm.
