Defenses of the Florida Apple Snail Pomacea Paludosa
Behaviour, 1971Abstract1. Pomacea paludosa exhibits a variety of defenses against predation, including aposematic eggs and dropoff-burial responses to odors of turtles, odors of crushed conspecific snails, and mechanical disturbance. 2. The conspicuous pinkish-white eggs are laid out of the water and hatch after several weeks incubation.

Imposex in the golden apple snail Pomacea canaliculata in Taiwan
Science of The Total Environment, 2006The golden apple snail Pomacea canaliculata (Lamarck, 1822) was introduced into Taiwan intentionally in the early 1980s and has become a recurring pest that seriously threatens aquatic crops. In this study, a field description of imposex with a developed penis sheath and penis in female golden apple snails from crop/domestic wastewater drainage sites ...

Nitrate impacts on the Florida apple snail, Pomacea paludosa
Hydrobiologia, 2006Nitrate pollution in springs in Florida has been suggested as a possible reason for declining populations of the Florida apple snail, Pomacea paludosa (Say). No correlation was found between snail density and nitrate concentration measured in six Florida springs.

Metabolism of Carotenoids in the Apple Snail, Pomacea canaliculata
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997Abstract Feeding experiments with β , β -carotene, canthaxanthin, (3 R ,3′ R )-zeaxanthin, (3 R ,3′ R ,6′ R )-lutein and racemic astaxanthin on the apple snail Pomacea canaliculata were investigated. Based on the experimental results, β , β -carotene was oxidatively metabolized, and the resulting principal metabolic product (3 S ,3′ S ...

Modeling apple snail population dynamics on the Everglades landscape
Landscape Ecology, 2015The Florida Everglades has diminished in size and its existing wetland hydrology has been altered. The endangered snail kite (Rostrhamus sociabilis) has nearly abandoned the Everglades, and its prey, the apple snail (Pomacea paludosa), has declined.

Evidence of oligogenic sex determination in the apple snail Pomacea canaliculata
Genetica, 2018A small number of genes may interact to determine sex, but few such examples have been demonstrated in animals, especially through comprehensive mating experiments. The highly invasive apple snail Pomacea canaliculata is gonochoristic and shows a large variation in brood sex ratio, and the involvement of multiple genes has been suggested for this ...

Symbionts and diseases associated with invasive apple snails
2017This contribution summarizes knowledge of organisms associated with apple snails, mainly Pomacea spp., either in a facultative or obligate manner, paying special attention to diseases transmitted via these snails to humans. A wide spectrum of epibionts on the shell and operculum of snails are discussed.
