TLDR
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.Abstract:
Apple snails (Ampullariidae:
Pomacea
) native to the New World have become agricultural and environmental pests widely in southern and eastern Asia since their introduction in about 1980. Although their impacts have been extensively documented, considerable confusion persists regarding their identities and geographical origins. Efforts to resolve the confusion have suffered from inadequate taxonomic and geographical sampling from both native and introduced ranges. Using phylogenetic and genealogical methods, we analysed 610–655 bp of cytochrome c
oxidase subunit I DNA sequences from 783 apple snails from 164 Asian locations and 57 native South American locations. In Asia, we found four species of Pomacea
in two clades: (1) Pomacea canaliculata
and P. insularum
, and (2) P. scalaris
and P. diffusa
. 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. Molecular analyses are consistent with early accounts; non-native P. canaliculata
populations trace back to multiple locations in Argentina and have probably been introduced more than once. In contrast, P. insularum
was probably introduced from Brazil and Argentina independently. Multiple introductions may, in part, explain the success and rapid spread of these two species. Unlike
P. canaliculata
and
P. insularum
,
P. scalaris
and P. diffusa
were probably introduced through the aquarium trade, derived originally from Argentina and Brazil, respectively. Possible physiological, ecological, and native range differences among these four species highlight the importance of accurate identification in understanding invasion patterns and processes, which is vital in developing and implementing management strategies.read more

Alien species in fresh waters: ecological effects, interactions with other stressors, and prospects for the future
TL;DR: Biological invasions are numerous in fresh waters around the world and the number of alien species in freshwater ecosystems will increase in the future as new aliens are moved outside of their native ranges by humans, and as established aliens fill their potential ranges.

TL;DR: 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.

TL;DR: Evidence for the impact of apple snails on natural and managed wetlands focusing on those studies that have elucidated impact mechanisms is reviewed, finding that greater attention to impact monitoring is required.

TL;DR: Generalist herbivores preferred non-native plants, suggesting that intact guilds of native, generalist herbsivores may provide biotic resistance to plant invasions.

Confidence limits on phylogenies: an approach using the bootstrap.
TL;DR: The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.

TL;DR: Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.
