Proteomic similarity of the Littorinid snails in the evolutionary context [PDF]

open access: yesPeerJ, 2020
Background The introduction of DNA-based molecular markers made a revolution in biological systematics. However, in cases of very recent divergence events, the neutral divergence may be too slow, and the analysis of adaptive part of the genome is more ...

No Tail No Fail: Life Cycles of the Zoogonidae (Digenea)

open access: yesDiversity, 2023
The Zoogonidae is the only digenean family where known cercariae lack the tail but actively search for the second intermediate host. However, the data on the zoogonid life cycles are scarce. In the present study, we elucidated and verified life cycles of

Premating barriers in young sympatric snail species

open access: yesScientific Reports, 2021
Sympatric coexistence of recently diverged species raises the question of barriers restricting the gene flow between them. Reproductive isolation may be implemented at several levels, and the weakening of some, e.g.

Nematocyst sequestration within the family Fionidae (Gastropoda: Nudibranchia) considering ecological properties and evolution

open access: yesFrontiers in Zoology, 2022
Aeolid nudibranchs are well-known for their ability to incorporate cnidarian nematocysts and use them for defense; this process is tightly linked with the feeding preferences of molluscs.
