Towards a phylogeny of gastropod molluscs: an analysis using morphological characters
This is one of the first attempts to use Morphological and developmental characters to assess the relationships of all major clades using parsimony methods and discusses the major monophyletic groups within gastropods.
The Global Decline of Nonmarine Mollusks
An overview of global nonmarine molluscan biodiversity and conservation status is provided, including several case studies documenting the diversity and global decline of nonmarinemollusks.
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.

Gastropod evolutionary rates and phylogenetic relationships assessed using partial 28S rDNA and histone H3 sequences
The data support the monophyly of the Patellogastropoda (true limpets), Euthyneura and the ‘higher’ vetigastropods and the polyphyly ofThe ‘Cocculiniformia’, and show marked variability in the rate of evolution in both segments of the 28S rDNA, whether or not the expansion regions are included.
Evaluation of Museum Collection Data for Use in Biodiversity Assessment
A methodology to evaluate museum collection data, in particular the reliability of distributional data for narrow-range taxa, and GIS was used to model predicted distributions of species based on abiotic data, providing an objective means to assess the likelihood of the distributions obtained from museum collection records representing true distributions.
Pushing short DNA fragments to the limit: Phylogenetic relationships of 'hydrobioid' gastropods (Caenogastropoda: Rissooidea).
Molecular phylogenetics of Caenogastropoda (Gastropoda: Mollusca).
Genetic differentiation of aquatic snails (Gastropoda: Hydrobiidae) from artesian springs in arid Australia
The findings suggest that if genetic diversity is to be conserved, current management strategies protecting only single springs within a group are inadequate, and one new species is described.
