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.
Global diversity of gastropods (Gastropoda; Mollusca) in freshwater
TLDR
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.
Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families
TLDR
A fully ranked, hierarchical classification summarizes recent advances in the phylogeny of the Gastropoda and Monoplacophora.
Comparing apples with apples: clarifying the identities of two highly invasive Neotropical Ampullariidae (Caenogastropoda)
TLDR
The taxonomy is clarified, the morphological and genetic distinctiveness of the two species are described, and their biogeographic ranges are re-evaluate.
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.
Character Coding and Inapplicable Data
TLDR
Coding inapplicables as “?” (reductive coding), although flawed, is currently the best way to analyze data sets that contain inappLicable character states.
Investigating the Bivalve Tree of Life – an exemplar-based approach combining molecular and novel morphological characters
TLDR
An analysis of the informativeness of morphological characters showed that sperm ultrastructure characters are among the best morphological features to diagnose bivalve clades, followed by characters of the shell, including its microstructure.
Refining molluscan characters: morphology, character coding and a phylogeny of the Caenogastropoda
TLDR
Character optimization revealed that the evolution of midgut structure is highly mosaic, cutting broadly across patterns of feeding, diet and foregut complexity, to a degree previously unappreciated, demonstrating that the gut is an unexploited resource for important and informative characters in higher order systematics of caenogastropods.
Insights from an Integrated View of the Biology of Apple Snails (Caenogastropoda: Ampullariidae)
TLDR
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.
Rubyspira, New Genus and Two New Species of Bone-Eating Deep-Sea Snails With Ancient Habits
TLDR
Molecular phylogenetic and morphological evidence places Rubyspira in an exclusively deep-sea assemblage that includes several close relatives previously known as fossils associated with Cretaceous cold seeps, plesiosaur bones, and Eocene whalebones.
