Distribution, abundance, population structures, and potential impacts of the invasive snail, Tarebia granifera in aquatic ecosystems of north-eastern South Africa. [PDF]

Ecol Evol
The study investigates Tarebia granifera, a highly successful aquatic invader, in South Africa's Limpopo and Phongolo River systems. The study revealed that T. granifera dominates in habitats where it is present, negatively impacting native molluscan species. Interestingly, the study did not find significant correlations between T.

The effect of mating on female reproduction across hermaphroditic freshwater snails

Invertebrate Biology, Volume 139, Issue 1, March 2020., 2020
Abstract Sexual conflicts often arise between mating partners because each sex tries to maximize its own reproductive success. One major male strategy to influence a partner's resource allocation is the transfer of accessory gland proteins. This has been shown to occur in simultaneous hermaphrodites as well as in organisms with separate sexes. Although
