Science of the Total Environment, 2020
Accelerating CO2 emissions have driven physico-chemical changes in the world's oceans, such as ocean acidification and warming. How marine organisms adjust or succumb to such environmental changes may be determined by their ability to balance energy ...

DNA barcoding for identification of marine gastropod species from Hainan island, China
, 2020Morphological identification of gastropods can be difficult considering the larva of species and high similarity among the same genera. DNA barcoding has been widely used in species identification and biodiversity research.

Molecular Phylogenetics and Evolution, 2019
Long-branch attraction (LBA) is a well-known artifact in phylogenetic reconstruction. Sparse taxon sampling and extreme heterogeneity of evolutionary rates among lineages generate propitious situations for LBA, even defying probabilistic methods of ...

Calcified arteries in a gastropod
Calcified Tissue Research, 1977The anterior aorta and major arteries of the land pulmonate snail Anguispira alternata have large calcium deposits in their walls. These deposits occur inside spherule cells, which line the walls of these vessels. The calcium occurs as amorphous calcium carbonate, in the form of intracellular spherules having alternating layers of organic and inorganic

Environmental Pollution, 2019
The rapid dissemination of microplastics in many habitats of the oceans has raised concerns about the consequences for marine biota and ecosystems. Many adverse effects of microplastics on marine invertebrates are consequences of ingestion.

The diet and feeding rates of gastropod grazers in Singapore’s seagrass meadows
Botanica Marina, 2018A wide variety of organisms are known to graze on seagrasses and their associated epiphytes, and this plant-animal interaction can affect the health of seagrass meadows.

Pleurotomarioidean gastropods are continuously present in the fossil record since the Upper Cambrian and survive into the Recent fauna, thus providing rare insights into the evolutionary history of the class Gastropoda. Pleurotomarioidea achieved greatest numerical and morphological diversity during the Paleozoic, and dominated global shallow water ...

Over their 500 million yearhistory, gastropods have radiated into marine, freshwater and terrestrial environments and adopted life styles ranging from herbivory to carnivory to endoparasitism to symbiont-mediated chemoautotrophy. They contend with many pathogens, including several lineages of specialized eukaryotic parasites.

Abstract The phylum Mollusca is second only to the Anthropoda in number of species. The molluscan lineage has been extremely plastic, and a great variety of structural plans have appeared. Of the seven classes of molluscs (Fig. 1.1), the largest is Gastropoda, which accounts for about 80% of the extant fauna.

Fossil gastropods seem to be ideally suited for studies of heterochrony. The description and analysis of heterochrony in evolutionary sequences require a detailed understanding of the ontogeny of the organisms involved. Not only must the ontogeny be well-preserved in its entirety, but the basic parameters underlying growth must be amenable to ...
