Sentence examples for multiple speciation modes from inspiring English sources

In fact, our results bear visual similarities to the modeled data under multiple speciation modes [ 43].

Multiple speciation events create a tree structured system of relationships between species.

To overcome the limitations of these auxiliary assumptions, the model has been extended to include different speciation modes, such as random fission [13], [14], abundance-independent speciation rates [15], [16] and protracted speciation [17].

In order to calculate speciation rates and assess speciation modes, a robust and detailed phylogenetic framework is required in order to determine evolutionary relationships and timing of cladogenetic events [41] [42].

Recently, broader phylogenetic approaches have provided insights into the relative importance of alternative speciation modes [ 53- 55].

Theory also suggests that several speciation modes are expected to result in an increase in substitution rate (see Discussion).

These settings provide better grounds for testing alternative speciation modes, due to the general lack of barriers to gene flow.

Hard polytomies reflect genuine multiple speciation events, so they cannot be represented as bifurcating trees.

However, a few studies have indicated the existence of multiple speciation times across these genomes, implying that human and chimpanzee experienced a complex speciation history.

In the case of mimicry shifts, it seems most likely that the intermediate intercept is the result of a mixture of speciation modes (i.e. speciation sometimes occurs with a mimicry shift, and sometimes without).

However, while numerous examples of species pairs likely to have originated by resource shifts have been found, the overall importance of ecological speciation in relation to other, non-ecological speciation modes remains unknown.
