This survey of freshwater gastropods within Nebraska includes 159 sample sites and encompasses the four primary level III ecoregions of the State. I identified sixteen species in five families. Six of the seven species with the highest incidence, Physa gyrina, Planorbella trivolvis, Stagnicola elodes, Gyraulus parvus, Stagnicola caperata, and Galba humilis were collected in each of Nebraska’s four major level III ecoregions. The exception, Physa acuta, was not collected in the Western High…

A review of the non-indigenous Chinese mystery snail, Cipangopaludina chinensis (Viviparidae), in North America, with emphasis on occurrence in Canada and the potential impact on indigenous aquatic species
Evidence suggests that the Chinese mystery snail, Cipangopaludina chinensis, a freshwater, dioecious, snail of Asian origin has become invasive in North America, Belgium, and the Netherlands.
Invasive Potamopyrgus antipodarum (New Zealand mud snails) and native snails differ in sensitivity to specific electrical conductivity and cations
When species are introduced to novel environments, abiotic conditions must be suitable for species to become invasive. For example, water chemistry must be acceptable for aquatic non-natives to

The Freshwater Gastropods of Iowa (1821-1998): Species Composition, Geographic Distributions, and Conservation Concerns
TLDR
Compared with data summarized in this review, it appears that as many as 18 species are now imperiled or extirpated from Iowa, and an additional 7 species were much less widespread at the end of the 20th century than formerly.
Conservation Status of Freshwater Gastropods of Canada and the United States
TLDR
Comparison of modern to background extinction rates reveals that gastropods have the highest modern extinction rate yet observed, 9,539 times greater than background rates.
The Freshwater Mussels ( Mollusca: Bivalvia: Unionoida ) of Nebraska
This paper reports the results of the first statewide survey of the freshwater mussels of Nebraska. Survey goals were: (1) to document current distributions through collection of recent shells; (2)
The conservation ecology of North American pleurocerid and hydrobiid gastropods
TLDR
Several research avenues are suggested that are needed to maintain and restore pleurocerid and hydrobiid snail populations in North American freshwater mollusks.
Species Composition of Nebraska's Freshwater Gastropod Fauna: A Review of Historical Records
TLDR
The number of species expected to be present in Nebraska to 31, including one non-indigenous species, is reduced to 31 based on known geographic ranges and systematic studies, and I suspect eight species are rare based on the number of records.
New Zealand mudsnails (Potamopyrgus antipodarum) in Boulder Creek, Colorado: environmental factors associated with fecundity of a parthenogenic invader.
TLDR
New Zealand mudsnails (Potamopyrgus antipodarum (Gray, 1853) are non-native snails that are increasingly spreading in freshwater systems in North America and water temperature, snail shell length, water hardness, and nutrient levels are examined.
The Global Decline of Nonmarine Mollusks
TLDR
An overview of global nonmarine molluscan biodiversity and conservation status is provided, including several case studies documenting the diversity and global decline of nonmarinemollusks.
Population estimate of Chinese mystery snail ( Bellamya chinensis )in a Nebraska reservoir
TLDR
A mark-recapture approach was utilized to generate a population estimate for Chinese mystery snail in Wild Plum Lake, a 6.47-ha reservoir in southeast Nebraska, and it was calculated that there were approximately 664 adult snails within a 127 m 2 transect.
A review of freshwater gastropod conservation: challenges and opportunities
TLDR
This special issue reviews 4 specific areas of concern regarding freshwater gastropod conservation strategies, taxonomy and systematics, ecological research, and conservation challenges, and offers suggestions for the direction of cooperative conservation with regard to freshwater Gastropods.
Not knowing, not recording, not listing: numerous unnoticed mollusk extinctions.
TLDR
It is suggested that assessment of the conservation status of invertebrate species is neglected in the IUCN Red List and not managed in the same way as for vertebrate species.
