Aquatic Toxicology
Aquatic pollution caused by pesticides raises concerns about the effects on wildlife. While risk assessment protocols with invertebrates focus mainly on arthropods, the effects on gastropods are underexplored.

Biological invasion represents one of the major threats to global biodiversity as alien species often displace indigenous species. Knowledge of the mechanisms behind such displacements and the driving factors of the competitive superiority of the alien species remain limited.

The influence of TCS on the growth and behavior of the freshwater snail,Physa acuta
Journal of Environmental Science and Health, Part A, 2012Triclosan (TCS) is among the top 10 most persistent contaminants found in U.S. rivers, streams, lakes, and aquifers. Although TCS has not been found to be hazardous to humans, it can be toxic to aquatic environments and animals. The effects of TCS on growth rates and the locomotive behavior of the freshwater snail, Physa acuta, were studied by exposing

Effects of different ionic compositions on survival and growth of Physa acuta
Aquatic Ecology, 2007Most inland saline waters in southern Australia predominantly contain Na+ and Cl− as major ions. The proportions of Ca2+, Mg2+, SO4 2−, HCO3 − and CO3 2− in these waters somewhat vary and might influence salinity tolerance of freshwater organisms.

Microsatellite variation in the freshwater snail Physa acuta
Molecular Ecology Notes, 2002AbstractWe present data for seven new markers isolated from a microsatellite‐enriched DNA library from the freshwater snail Physa acuta. Six of them appear to be conserved in Physa cubensis. These loci might be useful for analysing population structure and reconstructing the story of invasion of freshwaters on a worldwide scale by P. acuta.

The growth and reproduction of the freshwater snail Physa acuta (Gastropoda: Physidae) were measured at various salinity levels (growth: distilled water, 50, 100, 500, 1000 and 5000 microS/cm; reproduction: deionized water, 100, 500, 1000 and 3000 microS/cm) established using the artificial sea salt, Ocean Nature.

Identification and characterization of a goose-type lysozyme from sewage snail Physa acuta
Fish & Shellfish Immunology, 2014Freshwater snail Physa acuta has been considered as an important invasive species and medical mollusc. Field investigation has shown that this snail could survive better than other snails in polluted water bodies. To understand the immune mechanisms of P. acuta, suppression subtractive hybridization hepatopancreas cDNA library has been constructed with

Three morphogenetic waves in early development of Physa acuta (gastropoda, pulmonata)
Cell Biology International Reports, 1985Evidence is presented that there are three morphogenetic waves in early development of Physa acuta: a) around 24-cell stage, b) at early gastrula, and c) at early trochophore, using a proflavin biological test. These morphogenetic maxima fit very well with three transcriptional maxima.

Prednisolone (PDS), a potent synthetic glucocorticoid is widely prescribed for its exceptional anti-inflammatory properties. Several studies have detected the environmental presence of PDS in water bodies which has led to an ecological concern for its toxicity to non-target aquatic biota. The present study investigated the effects of exposure to PDS on

Expansion of an invasive freshwater snail Physa acuta (Gastropoda: Physidae) in China
Molluscan Research, 2009The pulmonate freshwater snail Physa acuta Draparnaud, 1805 has been previously reported as an invasive species in China and many other parts of the world. Populations in Beijing and Shandong, Shanxi, Yunnan and Hubei Provinces are reported for the first time based on collections made between August and October 2007. The potential for further spread of
