MEDUSA detects, using a stepwise AIC approach, significant shifts of diversification rates across a given phylogeny by evaluating the fit of different pairwise birth-death models.
The association of a given emm type with multiple STs can arise following diversification of housekeeping genes, or by horizontal transfer of the emm gene.
Logistic regression was also used to identify influential variables to use P. juliflora as a source of income and for diversification of livelihood strategies in a given household.
In conclusion, our results show that transitions to myrmecochory through the convergent evolution of elaiosomes played an important role in the diversification of angiosperms, giving rise to lineages currently with c. 11,000 species, more than four percent of angiosperm species diversity.
Accordingly, correlations among individual stocks and the explanatory power of the market model for a typical stock have declined, whereas the number of stocks needed to achieve a given level of diversification has increased.
Comparisons between avian species and mammals allowed us to hypothesize that the observed mammalian innovations might have contributed to the diversification of mammals that give birth to live young.
Subsequent diversification of this lineage gave rise to the jawed vertebrates (gnathostomes), hagfish (for which genome-scale sequence data are currently limited), lamprey and several extinct lineages (Fig. 1 and Supplementary Note). Figure 1: An abridged phylogeny of the vertebrates.
Subsequent diversifications of Pseuduvaria gave rise to clade III at ca. 6.6 Mya (95% HPD: 9.5-3.8 Mya; Figure 3: node 5) and clades I-II collectively at ca. 5.6 Mya (95% HPD: 8.1-3.2 Mya; Figure 3: node 10); this might be linked to these global climatic oscillations, with evolutionary divergence promoted by the significantly warmer and wetter climate.
Whereas exon shuffling can drive the functional diversification of gene families over evolutionary time, the temporal and/or tissue specific alternative splicing of a gene can give rise to functional diversification of a single gene during the development of an organism.
In the same way that diversification of a stock portfolio mitigates risk, diversification of your skills and experiences can give you important adaptability in an uncertain job climate.
