Karyotype description of Pomacea patula catemacensis (Caenogastropoda, Ampullariidae), with an assessment of the taxonomic status of Pomacea patula.
Mitotic chromosomes of the freshwater snail Pomacea patula catemacensis (Baker 1922) were analyzed on gill tissue of specimens from the type locality (Lake Catemaco, Mexico). The diploid number of chromosomes is 2n = 26, including nine metacentric and four submetacentric pairs; therefore, the fundamental number is FN = 52, No sex chromosomes could be identified. The same chromosome number and m...
متن کاملFacultative and obligate symbiotic associations of Pomacea canaliculata (Caenogastropoda, Ampullariidae).
Pomacea canaliculata (Lamarck 1822) occurs mainly in lentic habitats throughout the lower Amazon basin and the Plata basin (Hylton-Scott, 1958; Martín et al., 2001). This Neotropical species has been introduced (ca. 1980) to several South East Asian countries for aquaculture, and has become a serious pest for rice and other crops (Halwart, 1994). Many Pacific islands are currently included in t...
متن کاملFossil record of Pomacea (Caenogastropoda: Ampullariidae) in Argentina and its paleoenvironmental implications.
In many aspects Pomacea canaliculata (Lamarck, 1822) is the best known native snail from Argentina, a fact that has been enhanced since its establishment as a serious rice plague in Asian rice fields (Estebenet et al., 2006). Notwithstanding, from a paleontological viewpoint, the knowledge of this species is far from being sound and integrated. The aims of our paper are to review the fossil rec...
متن کاملConchological variation in Pomacea canaliculata and other South American Ampullariidae (Caenogastropoda, Architaenioglossa).
Pomacea canaliculata (Lamarck, 1822) is a freshwater snail belonging to the family Ampullariidae, a taxon that includes Asian, African and American species collectively known as apple snails. P. canaliculata ranges from the Amazonas Basin (Brazil) to Tandilia and Ventania Mountain systems (Buenos Aires province, Argentina) and is the most widely studied snail in Argentina, being the object of d...
متن کاملJuvenile growth and survival of the apple snail Pomacea canaliculata (Caenogastropoda: Ampullariidae) reared at different constant temperatures
BACKGROUND Pomacea canaliculata is a freshwater snail that cultured under certain conditions could provide interesting rewards in research and aquaculture. P. canaliculata is usually reared at 25°C, though the optimal temperature for culturing this species, that balances growth and survival rates, is so far unknown. In this work we present results of growth and survival of cohorts reared in the...
