Molecular Ecology, EarlyView.ABSTRACT Speciation is rarely observable directly. A way forward is to compare pairs of ecotypes that evolved in parallel in similar contexts but have reached different degrees of reproductive isolation. Such comparisons are possible in the marine snail Littorina saxatilis by contrasting barriers to gene flow between parallel ecotypes in Spain and ...

Ecological and Mutation‐Order Speciation in Senecio
Molecular Ecology, EarlyView.ABSTRACT Natural selection shapes how new species arise, yet the mechanisms that generate reproductive barriers remain actively debated. Although ecological divergence in contrasting environments and mutation‐order processes in similar environments are often viewed as distinct speciation mechanisms, we show they can occur simultaneously and act as part

Land snails benefit from human alterations in rural landscapes and habitats
Ecosphere, 2017 Metapopulation functioning in the context of landscape and habitat structure is generally well understood. However, in human‐transformed landscapes, human disturbance may affect not only a species of interest but also biotic interactions in which that ...

Molecular Ecology, EarlyView.ABSTRACT Many ant species show dramatic shifts in behaviour when infected with parasites, but the molecular basis of these behavioural changes is not well understood. An example is the wood ant, Formica aserva, which serves as an intermediate host for the lancet liver fluke, Dicrocoelium dendriticum.

Molecular Ecology, EarlyView.ABSTRACT Hydrothermal vents can serve as natural laboratories to study speciation processes due to their fragmented distribution, often with geographic barriers between habitats. Two sympatric species of Rimicaris shrimps occur at vents on the Izu‐Bonin‐Mariana volcanic arc: Rimicaris loihi also occurs near Hawai’i and R.
