Desa Sungai Nibung is a village located in Teluk Pakedai District, Kubu Raya Regency, West Kalimantan. This one of the conservation areas established by Regional Government Kalimantan Province 2020. has high diversity natural resources, which gastropods. Gastropods are organisms that act as grazers, scavengers, and predators. These can live waters, coastal terrestrial. Its been reported to be m...

BACKGROUND Seed dispersal of ant-dispersed plants (myrmecochores) is a well studied ecosystem function. Recently, slugs have been found to act as seed dispersers of myrmecochores. The aim of our study was to (1) further generalize the finding that gastropods feed on seeds of myrmecochores and hence may act as seed dispersers, (2) to test whether gastropod body mass and the volume of diaspores h...

BACKGROUND Tarebia granifera (Lamarck, 1822) is originally from South-East Asia, but has been introduced and become invasive in many tropical and subtropical parts of the world. In South Africa, T. granifera is rapidly invading an increasing number of coastal lakes and estuaries, often reaching very high population densities and dominating shallow water benthic invertebrate assemblages. An asse...

Hepatotoxic microcystins (MCs) produced by cyanobacteria are known to accumulate in gastropods following grazing of toxic cyanobacteria and/or absorption of MCs dissolved in water, with adverse effects on life history traits demonstrated in the laboratory. In the field, such effects may vary depending on species, according to their relative sensitivity and ecology. The aims of this study were t...

First observations are reported of predator-prey relationships among gastropod mollusks of the depauperate, Indo-West Pacific derivative, intertidal and shallow subtidal benthic fauna of Easter Island. Conus miliaris, which will be reported in detail in a separate paper, and Pisania decapitata englerli prey on polychaete annelids; Mitraflavocingulata preys on sipunculans; and Neothais nesiotes ...

More than a century of speculation about the evolutionary origin of the contorted gastropod body plan has been inspired by adult anatomy and by long-standing developmental observations. The result has been a concept of gastropod torsion that I call the "rotation hypothesis." Under the rotation hypothesis, gastropods originated when all components of the visceropallium (shell, mantle, mantle cav...

Female masculinisation (FM) in gastropods (imposex, intersex and ovo-testis) has been documented in > 260 species globally. Biomonitoring studies use FM to indirectly assess the presence of tributyltin (TBT), a once popular biocide in antifouling paint, which has since been regulated. Laboratory studies confirm that FM in gastropods can be induced not only by TBT, but other tin (Sn) compounds, ...

Cercariae capricornia I–VI, six new cercariae putatively identified as belonging to the Acanthocolpidae, are described and named from prosobranch gastropods of the family Nassariidae collected from the intertidal zone in the Capricornia region, Central Queensland, Australia. Four species are reported from Nassarius olivaceus and two from N. dorsatus. The cercariae have a unique and complex thre...

This study aimed to investigate the community structure and distribution pattern of Gastropods in mangrove ecosystem Bolihutuo village. The was conducted February July 2021 two different stations. Community analysis carried out includes species composition, density, diversity, evenness, dominance, patterns by Morisita dispersion index. results showed that 13 gastropods were found from 8 familie...

One group of invertebrates that live in the mangrove ecosystem is Mollusks mainly Gastropods and Bivalves. They are associated with as life, shelter, spawning, also a place to get food support growth them. The purpose this reaserch was look at effect species substrate type on distribution (Gastropods Bivalves) Pelangan Village, district Sekotong, west Lombok regency. This descriptive explorativ...
