“…Indeed, some of these indicators have already been applied successfully in monitoring programmes e.g. the FORAM Index developed by Hallock et al (2003). Whilst most micro-and meiobenthic indicators show great potential for application to coral reefs, their widespread acceptance will depend on the availability of taxonomic expertise or genetic assays, or the development of simple protocols that overcome the need for species differentiation.…”

“…Micro-or meiobenthic bioindicators, especially foraminifera, were ranked high-priority bioindicators for use in long-and short-term monitoring programmes (Table 3). Methods such as the FORAM Index are based on easily quantifiable size classes, rather than species composition, thereby useful information can be obtained even by observers with limited taxonomic expertise (Hallock et al 2003). Foraminifera communities can be quantified simply by collecting replicate sediment samples on coral reefs, which may be dried and stored for later processing.…”

Bioindicators of changes in water quality on coral reefs: review and recommendations for monitoring programmes

2009

Effective environmental management requires monitoring programmes that provide specific links between changes in environmental conditions and ecosystem health. This article reviews the suitability of a range of bioindicators for use in monitoring programmes that link changes in water quality to changes in the condition of coral-reef ecosystems. From the literature, 21 candidate bioindicators were identified, whose responses to changes in water quality varied spatially and temporally; responses ranged from rapid (hours) changes within individual corals to long-term (years) changes in community composition. From this list, the most suitable bioindicators were identified by determining whether responses were (i) specific, (ii) monotonic, (iii) variable, (iv) practical and (v) ecologically relevant to management goals. For long-term monitoring programmes that aim to quantify the effects of chronic changes in water quality, 11 bioindicators were selected: symbiont photophysiology, colony brightness, tissue thickness and surface rugosity of massive corals, skeletal elemental and isotopic composition, abundance of macro-bioeroders, micro-and meiobenthic organisms such as foraminifera, coral recruitment, macroalgal cover, taxonomic richness of corals and the maximal depth of coralreef development. For short-term monitoring programmes, or environmental impact assessments that aim to quantify the effects of acute changes in water quality, a subset of seven of these bioindicators were selected, including partial mortality. Their choice will depend on the specific objectives and the timeframe available for each monitoring programme. An assessment framework is presented to assist in the selection of bioindicators to quantify the effects of changing water quality on coral-reef ecosystems.

“…Concentrations of nutrients were high in reef-flat seawater near densely populated islands, resulting in both direct and indirect negative effects on foraminifera through habitat changes and/or the collapse of algal symbiosis (Osawa et al 2010). Such reduced water quality on coral reefs caused changes in benthic foraminiferal communities (Hallock et al 2003;Uthicke and Nobes 2008;Carilli and Walsh 2012). Large benthic foraminifera were rare or absent in the ocean reef flat of Majuro Atoll (Fujita et al 2009), in lagoons and ocean reef flats of the south Tarawa Atoll (Ebrahim 2000) and in the vicinity of wastewater outfalls on Enewetak Atoll (Hirshfield et al 1968).…”

Anthropogenic impacts on water quality of the lagoonal coast of Fongafale Islet, Funafuti Atoll, Tuvalu

et al. 2013

Water pollution, evident by negative values of redox potential in waters, occurs at the lagoonal coast located near the densely populated area of Fongafale Islet on Funafuti Atoll, Tuvalu, Central Pacific. Sediment microbial quinone analysis revealed that these coastal sediments exhibit 2.7-10.4 times more microbial biomass, significantly different microbial community structure and low microbial diversity, when compared to an undisturbed natural coastal sediment. Thus, the pollution is chronic. By considering the total land use/coverage on the islet, the situation of septic tank installations, temporal changes in water redox potential and Escherichia coli numbers in the coastal waters and the spatial distribution of acid volatile sulfide in the sediments, we conclude that domestic wastewater is the primary source of pollution. This pollution is proposed to occur via the following mechanism: during ebb tides, domestic wastewater leaking from bottomless septic tanks and pit toilets run off into the lagoonal coast. Tide changes control the pollution load of domestic wastewater.

“…Sampel tersebut dicuci dengan air yang mengalir dalam saringan 0,063 mm, lalu dikeringkan menggunakan oven pada suhu 50°C selama dua jam. Sampel foraminifera diletakkan pada foraminiferal slide untuk proses identifikasi menggunakan mikroskop binokuler dan diambil sebanyak 300 individu dalam setiap sampel (Hallock et al, 2003). Identifikasi yang digunakan mengacu pada Adisaputra et al (2010), Albani dan Yassini (1993), Barker (1960), Loeblich dan Tappan (1994), dan Nobes dan Uthicke (2008).…”
