Substantial incongruence among the morphology, taxonomy, and molecular phylogeny of the land snails Aegista, Landouria, Trishoplita, and Pseudobuliminus (Pulmonata: Bradybaenidae) occurring in East
The present findings suggest that radical revision is required for the taxonomy of bradybaenid land snails, and these genera except for a few species should be tentatively assigned to a single genus as Aegista.
A speciation gene for left–right reversal in snails results in anti-predator adaptation
This study demonstrates that a speciation gene can be fixed in populations by positive pleiotropic effects on survival, and shows that stylommatophoran snail speciation by reversal has been accelerated in the range of pareatid snakes.
Cryptic genetic divergence and associated morphological differentiation in the arboreal land snail Satsuma (Luchuhadra) largillierti (Camaenidae) endemic to the Ryukyu Archipelago, Japan.
Molecular and morphological analyses of snails sampled from the entire range of S. largillierti indicate that the traditional taxonomy has overly depended on inadequate morphological difference and a priori information of island geography which resulted in oversimplification of complex speciation history in Luchuhadra.
Terrestrial invasion of pomatiopsid gastropods in the heavy-snow region of the Japanese Archipelago
The terrestrial invasion of Japanese Pomatiopsinae occurred at least twice beside the mountain streamlets of heavy-snow regions, which is considered the first case of this event in the area.
Viscosity of molten silicon and the factors affecting measurement
Abstract Viscosity of molten silicon has been measured to study the behavior, especially around the melting point, in order to supply useful information for the crystal growth of semiconductors. The
Long‐term stasis and short‐term divergence in the phenotypes of microsnails on oceanic islands
The phenotypic evolution of Cavernacmella in Ogasawara is characterized by a pattern of long‐term stasis and periodic bursts of change, which suggests that even lineages with phenotypesic conservatism could shift to an alternative state allowing rapid phenotyping divergence.
Reproductive Character Displacement in Genital Morphology in Satsuma Land Snails
This is the first demonstration of reproductive character displacement in genital characters in an organism other than insects and highlights the importance of analyzing previously overlooked genital morphologies in understanding the general mechanisms of prezygotic isolation in land snails.
Divergence in the shell morphology of the land snail genus Aegista (Pulmonata: Bradybaenidae) under phylogenetic constraints
It is suggested that ecological divergence is probably the cause of shell morphology divergence in land snails, resulting in the divergence in shell morphology and the independent evolution of morphologically similar species among different lineages.
Phylogeny of the land snails Bradybaena and Phaeohelix (Pulmonata: Bradybaenidae) in Japan
It is suggested that a further taxonomic revision of Japanese Bradybaenidae is needed and, to address this issue, genital anatomy is useful in addition to molecular phylogenetic analyses.
