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

Physa marmorata, originally described from the Lesser Antilles, was introduced into Africa before 1900 and has previously been reported from Bénin, Togo, Ghana, Nigeria and South Africa. Here we show that it is also common in temporary ponds, fish ponds, dams and streams in the La Mé and Agnéby basins, southern Ivory Coast.

The Southwestern Naturalist, 2011
Abstract Our objectives were to determine which habitat variables had the greatest influence on densities of the Three Forks springsnail (Pyrgulopsis trivialis) and pond snail (Physa gyrina), and to examine interactions between the two species. We measured density and several habitat variables in Three Forks Springs and Boneyard Bog Springs in east ...

The invasive freshwater snail Aplexa marmorata was shown to exhibit a univoltine reproductive pattern in two ecologically different habitats, a stable ornamental pond and a small, unstable lake. Generation times and the timing of egg-laying periods did, however, differ between these two sites.
