Environmental Pollution, 2005
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.

Toxicity of Imidazolium-Based Ionic Liquids onPhysa Acutaand the Snail Antioxidant Stress Response
Journal of Biochemical and Molecular Toxicology, 2013In the present study, the acute and developmental toxicities of imidazolium ionic liquids (ILs) with different alkyl chain lengths, as well as the antioxidant response and lipid peroxidation levels were evaluated in the snail, Physa acuta. Longer alkyl chains corresponded to increased IL toxicity in snails. Long-term IL exposure at lower concentrations

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

Abstract. It has long been speculated that Physa acuta, a pulmonate snail widespread and invasive in fresh waters of the old world, may have originated in North America. But the identification of a new‐world cognate has been complicated by the confused systematics and taxonomy of the Physidae in America.

The exchange of phosphorus in shells of the aquatic snailPhysa acuta
Experientia, 1956In Schalen von wachsenden Wasserschnecken,Physa acuta, wurde binnen 5 Tagen 50 % Austausch des Radiophosphors32P beobachtet. Auch wurde festgestellt, dass das absolute Quantum des32P, der binnen 5 Tagen aufgenommen wird, indirekt proportional dem Schalengewicht ist, das heisst, je schwerer die Schale ist, desto mehr32P wird aufgenommen.

NO REPRODUCTIVE ISOLATION BETWEEN FRESHWATER PULMONATE SNAILS PHYSA VIRGATA AND P. ACUTA
The Southwestern Naturalist, 2005Abstract Mate choice tests provided no evidence of prezygotic reproductive isolation between a population of Physa virgata (Gould, 1855) collected from its type locality in the Gila River of Arizona and Physa acuta (Draparnaud, 1805) from a control site in Charleston, South Carolina.
