“…Recent studies have extensively documented foraminiferal test deformities from areas contaminated by heavy metals or other chemicals due to domestic sewage, and/or hydrocarbon spills (Resig, 1960;Alve, 1991;Yanko et al, 1998;Geslin et al, 1998;Samir, 2000;Geslin et al, 2002, Vilela et al, 2004Buzas-Stephens and Buzas, 2005;Meriç et al, 2005;Cevison and Hallock, 2007;Luciani, 2007;Fontalini and Coccioni, 2008;Polodova and Schönfeld, 2008;Madkour and Ali, 2008;Debenay et al, 2009;Martínez-Colón et al, 2009). However, it is important to emphasize that anthropogenic pollution is not always the cause of abnormal test formation (Stouf et al, 1999a).…”

During the early Maastrichtian an assemblage rich in large foraminifera, mostly composed of orbitoidal foraminifera, developed in the shallow-water deposits of the Cárdenas Formation (Valles-San Luis Potosí Platform, Mexico). Among them, the most abundant is Lepidorbitoides minima, some of which display a morphologically abnormal test consisting of polyvalent forms, conical tests and budding, which could be induced by abrupt changes in environmental factors. The occurrence of the abnormalities preceded the demise of this species and of all the larger foraminiferal association in the upper part of the Gansserina gansseri Zone (early Maastrichtian). The abnormalities could be induced by environmental stress, probably related to interplay of different events such as increased terrigenous input and the transition to deeper facies due to Laramide tectonic instability before the K/P boundary.A late Maastrichtian community of dwarfed planktic foraminifera composed of Trinitella scotti Brönnimann, Plummerita reicheli Brönnimann, Rugoglobigerina cf. macrocephala Brönnimann, Rugoglobigerina hexacamerata Brönnimann, Heterohelix punctulata (Cushman), Pseudoguembelina costulata (Cushman), Pseudotextularia intermedia de Klasz, Globigerinelloides asperus Bolli, Guembelitria cretacea Cushman, Rugoglobigerina rugosa (Plummer), Rugotruncana sp., Globotruncanita stuarti (de Lapparent), and Globotruncana arca (Cushman) developed in the upper part of the sequence. This uncommon morphology could also be related to the highly stressed paleoenvironmental conditions related to global climatic change and local tectonic activity. Associated with this planktic assemblage is a deeper-water dwarfed benthic foraminiferal community composed of Gyroidinoides nitidus (Reuss), Coryphostoma incrassata (Reuss), Pseudouvigerina plummerae Cushman, P. cretacea Cushman, Bolivina cretosa Cushman, Planulina texana Cushman and Cibicides harperi (Sandidge).Keywords: Abnormal foraminifera tests, Lepidorbitoides minima, dwarfed planktic foraminfera, Maastrichtian, Cárdenas Formation, Valles-San Luis Potosí Platform.

“…Fenomena ini terjadi baik pada biota planktonik maupun bentik. Sebagai contoh jenis foraminifera Ammonia beccarii selalu ditemukan sebagai jenis dominan di perairan sepanjang pesisir (Rositasari, 2000(Rositasari, , 2011(Rositasari, , 2012Samir, 2000;Gapotchenko et al, 2000;Alve, 1995;dan Burone & Vanin, 2006). Rendahnya keanekaragaman jenis foraminifera bentik di sepanjang perairan pesisir disamping karena secara alamiah keanekaragaman jenis di wilayah ini memang rendah (Murray, 2006), juga karena rentannya perairan ini terhadap tekanan ekologis.…”

Coastal water is vulnerable to anthropogenic substances such as human activities by product in coastal land and upper land area. Semarang coastal area is one of areas which has progressive development in northern coastal of Java Island. The aim of this study was to evaluate ocean health status based on heavy metal contain and benthic foraminiferal characteristics as the bioindicator. Sampling and laboratory activities were carried out in August 2010. Sampling stations were located on the estuaries of Western Canal Flood, Tanjung Mas Port and Eastern Canal Flood. The result showed that Tanjung Mas pool port had the highest Pb, Zn,and Total Organic Compounds (TOC) concentrations. The average of abnormal test of benthic foraminiferal (Ammonia beccarii) were also higher in Tanjung Mas port than in eastern and western canal flood. Keywords: assessment, coastal water, Semarang.

“…Ammonia beccarii merupakan jenis yang memperlihatkan persentase hidup dan abnormalitas cangkang paling tinggi di daerah muara (Rositasari, 2006). Deformasi morphologis pada cangkang foraminifera telah dicatat sejak sepuluh tahun yang lalu (Samir, 2000;Alve, 1995;Rositasari, 2006 (Rositasari et al, 2011).…”

Jakarta bay is a unique water since there are hydrological and ecological complexity. In general, the feature of these water consist of three ecological elements that are estuaries, coral reefs and open sea. Each of these ecological element has different hydrology, ecology as well as biological characteristics. As a form of meiobenthic community, foraminifera has adaptive behavior to each of ecological element of the waters. The observation on foraminiferal adaptive behavior due to the hydrological condition of Jakarta Bay was conducted from 2003 to 2009. The result showed that foraminiferal distribution was tend to pursue to the degradation water conditions and constructed a specific pattern. Coastal water and estuary were found dominated by Ammonia beccarii, Calcarine and other larger benthic foraminifera were common in coral reef area, Elphidium and Nonion depressulum were common in open waters area. Based on the diversity indices, the foraminifera in Jakarta Bay has a higher diversity compared to foraminifera in the coastal water of Semarang and Cirebon and among the ecological element of Jakarta Bay, reef area has the highest diversity index than coastal nor open sea area.Keywords: Foraminifera, Calcarine, Jakarta Bay
