The effects of size, reproductive condition, and parasitism on foraging behaviour in a freshwater snail,Potamopyrgus antipodarum
Abstract Predation risk is expected to affect the foraging behaviour of individual prey according to their size, sex and reproductive condition. Parasites may also affect the foraging behaviour of… Expand
The Invasive New Zealand Mud Snail (Potamopyrgus antipodarum) in Lake Erie
ABSTRACT The New Zealand mud snail (Potamopyrgus antipodarum) is an invasive species in Europe, Japan, Australia, and North America. In the western United States it is a species of special concern… Expand
Parasite-induced change in host behavior of a freshwater snail: parasitic manipulation or byproduct of infection?
- E. P. Levri
- 1 May 1999
Host behavioral changes due to parasitism are often assumed to be adaptations of the parasite. However, behavioral effects of parasites may be a generalized response to parasitism and only… Expand
Trematode infection correlates with shell shape and defence morphology in a freshwater snail.
Parasitism often influences the phenotype of individuals. Many of the resulting changes are due to changes in resource allocation that come with infection. Here we examine the effect of a trematode… Expand
Perceived predation risk, parasitism, and the foraging behavior of a freshwater snail (Potamopyrgus antipodarum)
- E. P. Levri
- 1 October 1998
Foraging behavior can be influenced by such factors as predation risk, individual size, and parasite infection. Snails (Potamopyrgus antipodarum) placed in tanks with large rocks were exposed to four… Expand
Invasive genotypes are opportunistic specialists not general purpose genotypes
It is not clear which forms of plasticity in fitness‐related traits are associated with invasive species. On one hand, it may be better to have a robust performance across environments. On the other,… Expand
Spatial variation in susceptibility to infection in a snail-trematode interaction.
Parasites should be better at infecting hosts from sympatric populations than allopatric populations most of the time (parasite local adaptation). In a previous study of a population of snail… Expand

The trematode Microphallus sp. alters the behavior of its snail intermediate host, Potamopyrgus antipodarum, in ways that seem to increase transmission to its final host, e.g., waterfowl, and… Expand
The distribution of the invasive New Zealand mud snail (Potamopyrgus antipodarum) in streams in the Lake Ontario and Lake Erie watersheds
The invasive New Zealand mudsnail, Potamopyrgus antipodarum, is a small freshwater hydrobiid snail with populations in western US rivers and streams and in the Laurentian Great Lakes. The snail has… Expand
