Invasive species are one of the most serious threats to amphibian populations. We investigated the effects of two invasive (Pomacea canaliculata and Physella acuta) and one native (Radix sp.) snail species on five species of wetland-breeding frogs in Hong Kong. We quantified embryonic survivorship and determined whether particular attributes of amphibian egg masses influenced consumption by snails. P. canaliculata preyed on four of the species, consuming >90 % of eggs of Microhyla fissipes and… 

Silent assassins: predation of native New Zealand trichopteran eggs by non-native freshwater gastropods

The trichopteran egg masses tested did not succumb to predation by the native Potamopyrgus but are highly vulnerable topredation by a larger non-native snail.

This review aims to analyse the mechanisms of the impacts that these invasive Pomacea provoke or may provoke and to better understand the environmental impacts of invasive Pomace and their underlying mechanisms.

Invasive apple snails: Ecology and management in Hong Kong

It has become clear that P. canaliculata could have reduced wetland biodiversity by grazing on macrophytes and by predation on benthic invertebrates, and altered wetland function by releasing nutrients into the water.

Exotic Invasive Pomacea maculata (Giant Apple Snail) Will Depredate Eggs of Frog and Toad Species of the Southeastern US

A freshwater snail from South America that is an invasive species on the Gulf of Mexico coastal plain is shown to prey on amphibian eggs in Asia, and eggs of Lithobates palustris, Northern Leopard Frog, and Anaxyrus americanus are presented.

Identity, reproductive potential, distribution, ecology and management of invasive Pomacea maculata in the southern United States

This contribution reviews the distribution, life history, ecology and management of P. maculata introduced to the southern USA and confirms that these Asian populations represent at least two Pomacea species, P. canaliculata and P. Macintosh.

Responses of survival, growth, and feeding of the invasive Golden Apple Snail (Pomacea canaliculata) to salinity stress

The Golden Apple Snail Pomacea canaliculata (Lamark, 1822) is one of the most aggressive invasive freshwater snails and has been found in tropical and subtropical regions around the world. Their

Insights from an Integrated View of the Biology of Apple Snails (Caenogastropoda: Ampullariidae)

The great majority of the work to date concerns a single species, Pomacea canaliculata, which the authors see as having the potential to become a model organism in a wide range of fields, however, additional comparative data are essential for understanding this diverse and potentially informative group.

Carrion consumption and its importance in a freshwater trophic generalist: the invasive apple snail Pomacea canaliculata

The ability of P. canaliculata to profit from carrion may help explain its potential to establish widely and to have effects on aquatic vegetation.

Vulnerability and behavioral responses of South Chinese anuran tadpoles to native dragonfly (Pantala flavescens) naiads and introduced western mosquitofish (Gambusia affinis)

The results suggest that some of the tadpoles in the study area are likely to recognize and respond to the predation threats of Gambusia affinis, and may be adaptive in more permanent habitats.

Effects of macrophytes on feeding and life‐history traits of the invasive apple snail Pomacea canaliculata

It is indicated that, due to their higher nutritional value and lower chemical and physical defences, cultivated macrophytes are in general desirable for the apple snail which may partly explain its successful invasion into wet agricultural areas in Asia.

Are toad tadpoles unpalatable: evidence from the behaviour of a predatory dragonfly in South China

These findings present the first report of unpalatability of bufonid tadpoles to an invertebrate predator and provide evidence that unpal atability of early stage bufonids to odonates may decrease through ontogeny.

Shading Mediates the Interaction Between an Amphibian and a Predatory Fly

Although the risk of predation by calliphorid flies is higher for P. megacephalus in unshaded areas, the benefits of developing in warmer conditions, including faster embryonic and larval development and larger size at metamorphosis, may offset this risk.

Out of South America: multiple origins of non‐native apple snails in Asia

Parsimony networks and mismatch distributions indicate that the non‐native ranges of the two most widespread species, P. canaliculata and P. insularum, probably result from multiple introductions, which may explain the success and rapid spread of these two species.

Predation on newt eggs was studied in both natural (pond) and control conditions, suggesting predation as the major mortality risk and antipredator adaptations.

INVADING HERBIVORY: THE GOLDEN APPLE SNAIL ALTERS ECOSYSTEM FUNCTIONING IN ASIAN WETLANDS

This study demonstrates how an herbivore may trigger a shift from clear water and macrophyte dominance to a turbid state dominated by planktonic algae, and is detrimental to the integrity and functioning of wetland ecosystems, and to the services these provide in Southeast Asia.

Populations of the European freshwater pulmonate Physa acuta are not reproductively isolated from American Physa heterostropha or Physa integra

No-choice crosses each involving 2 populations of the widespread American species Physa heterostropha and Physa integra were designed to compare measures of reproductive success between species and between populations within species, but evidence of reproductive isolation was unable to be detected.

It is concluded that butachlor is likely to have widespread negative impacts on amphibians occupying paddy fields with traditional herbicide application.

Principal component analysis showed that the environmental characteristics of the study sites varied with habitat, and DFA revealed that the inhabited sites typically had high levels of phosphate and alkalinity, but the snail was also occasionally found in streams where dissolved ion concentrations and nutrient levels were low.
