MIMICRY AMONG MARINE MOLLUSCA

Mitochondrial DNA hyperdiversity and its potential causes in the marine periwinkle Melarhaphe neritoides (Mollusca: Gastropoda)

We report the presence of mitochondrial DNA (mtDNA) hyperdiversity in the marine periwinkle Melarhaphe neritoides (Linnaeus, 1758), the first such case among marine gastropods. Our dataset consisted of concatenated 16S-COI-Cytb gene fragments. We used Bayesian analyses to investigate three putative causes underlying genetic variation, and estimated the mtDNA mutation rate, possible signatures o...

Relationships among Facial Mimicry, Emotional Experience, and Emotion Recognition

BACKGROUND The relationships between facial mimicry and subsequent psychological processes remain unclear. We hypothesized that the congruent facial muscle activity would elicit emotional experiences and that the experienced emotion would induce emotion recognition. METHODOLOGY/PRINCIPAL FINDINGS To test this hypothesis, we re-analyzed data collected in two previous studies. We recorded facia...

Butterfly genome reveals promiscuous exchange of mimicry adaptations among species

The evolutionary importance of hybridization and introgression has long been debated. Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferring beneficial traits between species.Hereweuse genomic tools to investigate introgression inHeliconius, a rapidly radiating genus of neotropical butterflieswidely used in studies of ecology, behaviour,mimicry ...
