Evolutionary systematics of the viviparous gastropod Sermyla (Gastropoda: Cerithioidea: Thiaridae), with the description of a new species [PDF]

open access: yesZoological Journal of the Linnean Society, 2020
Abstract While most Cerithioidea are marine, some occur in brackish and freshwater habitats. Many members are systematically problematic due to variability or homoplasy in conchological characters, which has led to taxonomic redundancy, but also because of discrepancies between phylogenetic trees and morphologically distinguishable units

Morphological and Genetic Variation Between the Japanese Populations of the Amphidromous Snail Stenomelania crenulata (Cerithioidea: Thiaridae) [PDF]

open access: yesZoological Science, 2014
Freshwater gastropods often have limited dispersal capability and small geographic ranges, and face severe threats from habitat loss and degradation. However, in addition to the scarcity of knowledge on their life history traits, species taxonomy has not been adequately resolved and boundaries between intra- and interspecific variation remain unclear ...

Growth models and shell morphometrics of two populations of Melanoides tuberculata (Thiaridae) living in hot springs and freshwater pools

open access: yesJournal of Limnology, 2007
Two morphologically different populations of snail, Melanoides tuberculata (Muller, 1774), were observed at Azraq Oasis, Jordan. Snails at the hot spring, where water temperature is higher than ambient, looked larger than those at the pools.
