Nuptial feeding in the freshwater snail Pomacea canaliculata (Gastropoda: Ampullariidae)
(Institute of Malacology, 2007-12-01)
The males of the freshwater snail Pomacea canaliculata have a copulatory apparatus consisting in a delicate penis running through a muscular channeled sheath bearing three different glands. The outer gland is the most ...
Allometric and trophic effects on shell morphology of Pomacea canaliculata (Caenogastropoda, Ampullariidae) from a geometric morphometrics viewpoint
(Magnolia Press, 2013-04)
Pomacea canaliculata, an invasive apple snail native to South America, is a serious pest of aquatic crops in several parts of the world. The origin of inter-population variation in shell shape is thought to be both genetic ...
Life cycle of Pomacea americanista, a poorly known apple snail endemic to the Iguazú and Alto Paraná Rivers, southern South America
(Oxford University Press, 2018-02-18)
The Ampullariidae (apple snails) are freshwater snails of tropical and subtropical regions. Recent research has concentrated on a few species that are invasive or potential biocontrol agents, but the basic life history ...
Life cycle of the South American apple snail Asolene platae (Maton, 1811) (Caenogastropoda: Ampullariidae) under laboratory condition
(Oxford University Press, 2016-04)
Reproductive mode, life cycle and fecundity are relevant to understand and predict the spread and impacts of invasive freshwater molluscs. Ampullariids or apple snails have been intensively studied in recent decades due ...
Ongoing research into the natural history and ecology of an endemic and little known apple snail from the Alto Paraná and Iguazú rivers (Argentina)
(International Union for Conservation of Nature, 2015-02)
Most of the knowledge about the biology and ecology of Neotropical apple snails (family Ampullariidae) belongs to just three species out of the dozens that inhabit freshwater habitats distributed from the Florida Peninsula ...
Acute toxicity of apple snail Pomacea canaliculata’s eggs on Rhinella arenarum tadpoles
(Taylor & Francis, 2017-01)
The effect of the crude homogenate of snail Pomacea canaliculata’s eggs (CHSE) exposition on Rhinella arenarum tadpoles was investigated. Exposure to 10 g CHSE/L treatment produced 95% tadpole mortality, whereas the median ...
Imposex and novel mechanisms of reproductive failure induced by tributyltin (TBT) in the freshwater snail Pomacea canaliculata
(Setac Press, 2013-06)
The effects of TBT on mortality and reproduction were studied in this invasive snail. The nominal fifty percent lethal concentration (LC50) was 9 Dg TBT/L, after 28 days. The nominal no observed effect on lethality ...
Egg perivitelline fluid proteome of a freshwater snail: Insight into the transition from aquatic to terrestrial egg deposition
(John Wiley & Sons Ltd, 2019-10-28)
Rationale: Proteins from the egg perivitelline fluid (PVF) are assumed to play critical roles in embryonic development, but for many groups of animals their identities remain unknown. Identifying egg PVF proteins is a ...
Egg perivitelline fluid of the invasive snail Pomacea canaliculata affects mice gastrointestinal function and morphology
(PeerJ, 2018-07)
Background. Species beloging to the genus Pomacea (Ampullariidae), often referred as apple snails are freshwater, amphibious snails native to South, Central and North America. Some species such as P. canaliculata have ...
