“…The vertical distribution of foraminifera along the short core samples was dominated by rotaliids, a common group reported from intertidal (Malek et al, 2021) and subtidal environments (Minhat et al, 2014; along the Straits of Malacca. The dominance of A. pulchella in all core intervals is consistent with the foraminifera distribution observed along a longer core from the northern part of the Straits of Malacca (Minhat et al, 2019).…”

Abstract The Strait of Malacca—a shallow and hyposaline strait—is one of the busiest shipping routes in the world. It divides Sumatra and Peninsular Malaysia. This study assessed the sub- surface distribution of benthic foraminifera, their preservation, and their relationship with the sediment characteristics of the Strait of Malacca. One short sediment core sample was collected from the southern part of the Strait of Malacca. The core was then divided into 10 subsamples at every 2 cm interval. The samples were used for foraminifera identification and grain size and organic matter analysis. From the approximately 3000 benthic foraminifera that were selected and identified, 17 species exhibited ≥ 2% occurrence in at least one subsample along the core. Out of the 17 species identified, 4 species (Asterorotalia pulchella (57%), Cavarotalia annectens (13%), Discorbinella bertheloti (7%), and Pseudorotalia schoerteriana (6%)) exhibited an average relative abundance of >5% in all core intervals. Cluster analysis subdivided the core intervals into two groups: BF1 and BF2. Both the groups were dominated by A. pulchella. The PCA biplot indicated that BF1, which represented the upper sub-surface intervals, had relatively more agglutinated species than BF2. Despite being common in surface samples along the Strait of Malacca, species such as Textularia sp. were absent further down the core. This study indicated that in the sub-surface sediment of the Strait of Malacca, calcareous hyaline species, especially those belonging to Rotaliida, were abundant and readily preserved compared to the agglutinated or calcareous porcelaneous groups. The loss of several agglutinated groups down the cores indicated that a more discreet approach to paleoenvironmental interpretation using benthic foraminifera assemblages should be adopted in this region to avoid bias in the interpretation.

“…Common benthic foraminifera species that were found in mangrove ecosystems mostly consist of agglutinated taxa such as Ammotium morenoi , Arenoparrella mexicana , Haplophragmoides wilberti , Miliammina fusca , Entzia macrescens and Trochammina inflata , with some calcareous hyaline taxa (e.g. Ammonia tepida , Bolivina striatula , Elphidium fijiense , Elphidium hispidulum , Elphidium advenum ) (Scott et al ., 2004; Woodroffe et al ., 2005; Murray, 2006; Berkeley et al ., 2009 a , 2009 b ; Debenay, 2012; Culver et al ., 2013; Camacho et al ., 2015; Langer et al ., 2016; Abd Malek et al ., 2021).…”

Studies on benthic foraminifera were conducted in the mangrove forests of Teluk Tempoyak, Pulau Betong and Kuala Sungai Pinang, Penang Island, Peninsular Malaysia to examine species composition and distribution patterns in different intertidal zones. Twenty-eight live benthic foraminiferal species were successfully identified at the study locations, predominantly species with agglutinated tests. Assemblages in Pulau Betong and Teluk Tempoyak were dominated by similar species such as Ammonia aoteana, Elphidium hispidulum, Elphidium neosimplex and Trochammina inflata, while Kuala Sungai Pinang comprises a high number of Trochammina inflata and Arenoparrella mexicana. Three species, Aubignyna perlucida, Elphidium neosimplex and Elphidium sandiegoense, were recorded for the first time in Malaysian mangrove forests. Principal component analysis showed that sediment type and organic matter content were the dominant parameters that explained the variation of environmental gradient. Canonical correspondence analysis of these parameters with benthic foraminiferal species indicated that sand particles influenced distribution of the hyaline tests. Species with agglutinated tests were abundant in sediment with rich organic matter in combination with high silt and clay content. Species with hyaline tests dominated lower intertidal zones, while those with agglutinated tests inhabited the area from the middle to upper intertidal zones. This distribution pattern of benthic foraminiferal species mirrored patterns found at other local and global mangrove locations.

“…The proportion of foraminiferal species based on the wall material can be used to infer the type of general environment using a ternary plot (Murray, 2006). For example, assemblages characterised by high proportions of agglutinated taxa are commonly found in intertidal marshes (e.g., Culver et al, 2013;Malek et al, 2021).…”

“…Generally, foraminifera can be found in modern tropical mangrove associated deposits (e.g., Satyanarayana et al, 2014;Malek et al, 2021). For instance, in the Peninsular Malaysia, agglutinated foraminifera are documented from mangrove forests on the margins of the Setiu estuary (Culver et al, 2012) and mangrove swamps of Kemaman-Chuaki (Suriadi et al, 2021).…”
