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 ...

First record of the presence and reproduction of the two-tailed pasha Charaxes jasius (Linnaeus 1767) (Lepidoptera: Nymphalidae) in Northeastern Italy

open access: yesNatural History Sciences, 2022
Charaxes jasius (Linnaeus, 1767) is reported for the first time for the Veneto region, in Northeastern Italy. Both adults and caterpillars have been observed in the Euganean Hills (Colli Euganei Regional Park) between August and October 2021.

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.

Context-Driven Detection of Invertebrate Species in Deep-Sea Video [PDF]

open access: yesInternational Journal of Computer Vision 2023, 2022
Each year, underwater remotely operated vehicles (ROVs) collect thousands of hours of video of unexplored ocean habitats revealing a plethora of information regarding biodiversity on Earth. However, fully utilizing this information remains a challenge as proper annotations and analysis require trained scientists time, which is both limited and costly ...

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.

Learning processes in elementary nervous systems§ [PDF]

open access: yesJournal of Integrative Neuroscience, 2020
Invertebrate animal models show simple behaviors supported by neural circuits easily accessible for experimentation and yet complex enough to provide necessary information on the cellular and molecular mechanisms that govern the vertebrate nervous system'

Molecular signatures of the rediae, cercariae and adult stages in the complex life cycles of parasitic flatworms (Digenea: Psilostomatidae)

open access: yesParasites & Vectors, 2020
Background Parasitic flatworms (Trematoda: Digenea) represent one of the most remarkable examples of drastic morphological diversity among the stages within a life cycle.

Linking ecology, morphology, and metabolism: Niche differentiation in sympatric populations of closely related species of the genus Littorina (Neritrema)

open access: yesEcology and Evolution, 2021
Divergence of ecological niches in phylogenetically closely related species indicates the importance of ecology in speciation, especially for sympatric species are considered.

Single-cell RNA sequencing analysis of shrimp immune cells identifies macrophage-like phagocytes

open access: yeseLife, 2022
Despite the importance of innate immunity in invertebrates, the diversity and function of innate immune cells in invertebrates are largely unknown. Using single-cell RNA-seq, we identified prohemocytes, monocytic hemocytes, and granulocytes as the three ...
