The Benthic Foraminiferal Assemblages in the Seagrass Bed of Tanjung Berakit Waters, Bintan Island

Abstract

Seagrass is the most common ecosystem in Tanjung Berakit waters. Therefore, Tanjung Berakit waters have a very important role as a benthic foraminiferal habitat. This study was conducted to describe the distribution of benthic foraminifera relating to the environmental condition of the waters. The samples were collected from eight stations by handling garb in November 2017. This study collected 18 species of shallow water benthic foraminifera dominated by Amphistegina and Heterostegina. This study recorded a correlation between the sediment texture and foraminiferal assemblages. The most common foraminifera were inhabiting fine-textured sediments, especially very fine sand and silt. Only a few foraminifers are collected from extremely fine sediments such as clay sediments, or extremely coarse including pebbles.

Diversity of Harvested Gastropods in Guang-Guang, Mati City, Davao Oriental, Philippines

“…Strombidae is one of the most familiar molluscan groups composed of about 100 species that mostly live in sand, seagrass, and mud flats area, and they are considered the source of food in many tropical and subtropical regions all over the world (Oo 2018;Ardila et al 2020). However, Strombidae is affected by overexploitation caused by both natural and anthropogenic stressors, which leads to a large Natsir and Dillenia 2023). On the other hand, the other study in Zamboanga del Norte and Misamis Occidental, Philippines, showed that the most abundant species found in the selected area is the Canarium esculentum with 33.25% species, followed by the Canarium urceus with 17.49%, and the majority of the Strombidae species are found in the sandy-muddy substrate (Pangarungan et al 2022).…”
