ABSTRACT This is the first American Fisheries Society conservation assessment of freshwater gastropods (snails) from Canada and the United States by the Gastropod Subcommittee (Endangered Species Committee). This review covers 703 species representing 16 families and 93 genera, of which 67 species are considered extinct, or possibly extinct, 278 are endangered, 102 are threatened, 73 are vulnerable, 157 are currently stable, and 26 species have uncertain taxonomic status. Of the entire fauna…

The freshwater snails (Mollusca: Gastropoda) of Mexico: updated checklist, endemicity hotspots, threats and conservation status
An updated checklist of native Mexican freshwater gastropods is presented with data on their general distribution, hotspots of endemicity, threats, and for the first time, their estimated conservation status and identified 3 hotspots and 2 potential centers of gastropod endemicity.
Improving estimates of richness, habitat associations, and assemblage characteristics of freshwater gastropods
Freshwater gastropods are imperilled globally and are among North America's most vulnerable major animal groups. Habitat loss, invasive species, and inadequate information about species distributions
Patterns of Freshwater Species Richness, Endemism, and Vulnerability in California
Opportunities to fill gaps in the evaluation of conservation status for freshwater taxa in California are identified, to address the lack of occurrence information for nearly 40% of freshwaterTaxa and nearly40% of watersheds in the state, and to implement adequate protections for freshwatertaxa where they are currently lacking are identified.
The conservation status of the world’s freshwater molluscs
With the biodiversity crisis continuing unchecked, we need to establish levels and drivers of extinction risk, and reassessments over time, to effectively allocate conservation resources and track
Subterranean freshwater gastropod biodiversity and conservation in the United States and Mexico
The biology of stygosnails in North America is reviewed and conservation needs and policy considerations that will aid in their protection are discussed.
Distribution and Conservation Status of the freshwater gastropods of Nebraska
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

ABSTRACT The Edwards-Trinity Aquifer System of Texas, USA, one of the world's most ecologically diverse groundwater systems, contains 14 species (across seven genera) of small, poorly studied
A conservation assessment of the freshwater gastropods of South Dakota based on historical records and recent observations
A benchmark conservation status is established for the freshwater gastropods of South Dakota and a preliminary conservation evaluation indicates Planorbula armigera is critically imperiled, while three species; Ferrissia rivularis, Campeloma decisum, and Amnicola limosus are imperiled.
Nonindigenous Aquatic Mollusks in Illinois
Nonindigenous aquatic species (NAS), some of which are referred to as aquatic invasive species (AIS) or non-native aquatic species, are those aquatic organisms that have become established beyond

Compared to other regions, Texas’ groundwater fauna is not unique in terms of rarity and threat, suggesting that as an ecological group, groundwater-obligate species are probably among the world’s most imperiled taxa.


Conservation status of imperiled north American freshwater and diadromous fishes
This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989, and reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa.
Conservation Status of Freshwater Mussels of the United States and Canada
The American Fisheries Society herein provides a list of all native freshwater mussels (families Margaritiferidae and Unionidae) in the United States and Canada and a comprehensive review of the conservation status of all taxa.
Conservation Status of Crayfishes of the United States and Canada
It is estimated that almost 50% of crayfishes in United States and Canada are in need of conservation recognition, and it is hoped that this report spurs increased research efforts from aquatic ...

Global diversity of gastropods (Gastropoda; Mollusca) in freshwater
The world’s gastropod fauna from continental waters comprises ∼4,000 valid described species and a minimum of 33–38 independent lineages of Recent Neritimorpha, Caenogastropoda and Heterobranchia, but the status of the great majority of taxa is unknown, a situation that is exacerbated by a lack of experts and critical baseline data.
The conservation ecology of North American pleurocerid and hydrobiid gastropods
Several research avenues are suggested that are needed to maintain and restore pleurocerid and hydrobiid snail populations in North American freshwater mollusks.
Phylogeny, taxonomy, genetics and global heritage ranks of an imperilled, freshwater snail genus Lithasia (Pleuroceridae)
A phylogenetic analysis of the pleurocerid genus Lithasia using morphological and mitochondrial DNA sequence (mtDNA) data in an attempt to delimit species boundaries and test previous taxonomic schemes found that the current taxonomy of Lithasia does not reflect species diversity adequately within the genus.
Extinctions of North American Fishes During the past Century
Abstract Extinctions of 3 genera, 27 species, and 13 subspecies of fishes from North America are documented during the past 100 years. Extinctions are recorded from all areas except northern Canada
Fishes of North America Endangered, Threatened, or of Special Concern: 1989
Comparison of the 1979 and 1989 list of rare North American fishes indicates that recovery efforts have been locally effective for some species, but are cleverer than was earlier believed.
Conservation Genetics of a Critically Endangered Limpet Genus and Rediscovery of an Extinct Species
The data corroborated the taxonomic validity of Rhodacmea filosa and inferred a within-MRB cladogenic origin from a common ancestor bearing the R. elatior shell phenotype, and recommended the establishment of a proactive targeted conservation program that may include their captive propagation and reintroduction.
