Temporal Distribution of Gastropods In Rocky Intertidal Area In North Manokwari, West Papua

Abstract

Gastropods is an important organism that commonly found inhabiting the rocky intertidal area. Distribution pattern of this species is influenced by various factors such as population history, microhabitat, predation and a complex interactions between oceanographic dynamics and ecological features. This study aims to compare the temporal distribution pattern of gastropods at two different rocky intertidal area. This research was conducted at the rocky intertidal area of Amban and Nuni, North Manokwari District, West Papua. Data collection was performed during the daylight and night in April and June 2012 using systematic sampling method. The results showed that both physical and chemical factors are suite for supporting gastropods life. Furthermore, these factors seem to have an impact on gastropod zoning patterns observed in the study area. The similarity index values ​​indicate that the similarity of gastropod species between the two locations is low, which means that the species of gastropods found in each location is quite different. The community structure of gastropod at the study area is stable. In addition, we found that the gastropods diversity were higher during the night than the daylight because gastropods are classified as a nocturnal animals.

Community distribution and utilization of gastropods in the Coastal Area of Liki Island, Sarmi District, Papua, Indonesia

“…The study on the coastal area of Liki Islarmi collected 1812 gastropods, with a range of 182-603 individual gastropods within 6 sampling stations, consisting of 63 species of gastropods from 23 families (Table 2). This species' number and distribution showed that gastropods have a very wide distribution area and are often found in intertidal areas (Saleky et al 2019;Susintowati et al 2019). The community structure of gastropods was strongly influenced by changes in environmental factors (Hitalessy et al 2015;Septiani and Wiharyanto 2015;D'Souza et al 2022).…”

“…These species were commonly encountered in intertidal areas and showed adaptation to the substrate type and other environmental factors. One of those species, Monetaria annulus, usually known as 'ring cowrie,' is normally found in the intertidal and inhabits sandy and muddy -coastal areas, as well as reef flats with seagrasses or coral fractures (Aji et al 2018;Saleky et al 2019). The presence of the gastropods community and their distribution patterns generally occur because of the variability of environmental factors such as nutrition availability, substrate type, associations with other species, temperature and pH condition, and also oxygen content.…”

Pola Pertumbuhan dan Identifikasi Genetik Turbo setosus Gmelin, 1791 [Turbinidae, Gastropoda]

“…(Srimariana, 2015). T. setosus kebanyakan hidup pada daerah intertidal berbatu (Baharuddin, Basir, & Zainuddin, 2019;Saleky et al, 2019).…”

“…Hewan ini dapat mencapai ukuran 6 -7 cm dan berada di perairan yang tenang (Dharma, 2005) dan dapat ditemukan pada daerah intertidal berbatu di pesisir utara. Spesies T. setosus sering ditemukan hidup bersama dengan spesies lain seperti T. sparverius dan T. bruneus (Saleky et al, 2019(Saleky et al, , 2016.…”

Molecular Phylogenetic of Cerithidea anticipata (Iredale, 1929) (Mollusk: Gastropod)

“…Kata kunci: Cerithidea anticipata; Gen COI; DNA barcoding; filogenetik PENDAHULUAN Gastropoda Potamidae merupakan kelompok gastropoda yang sangat melimpah dan hidup pada ekosistem mangrove (Ratsimbazafy and Kochzius, 2018). Lebih dari 25 spesies gastropoda Potamidae melimpah pada ekosistem mangrove (Reid et al, 2008) yang penyebarannya sangat dipengaruhi oleh kondisi fisik-kimia perairan, subtrat dasar dan juga kondisi microhabitat (Saleky et al, 2019;Syahrial et al, 2020).…”
