Sentence examples for average diversification rate from inspiring English sources

However, even with a near complete sample of species, and potentially large differences in average diversification rate at given times, the differences between the two clades are only marginally significant in our present analyses.

Across the Bayesian samples, using the younger calibration yields an average diversification rate of 2.02 species/Myr (C.I. 1.16 to 3.12) with N = 898 (minimum species number for LM and LV flocks) [10], rising to 2.09 species/Myr (C.I. 1.71 to 3.19) with N = 1135 (maximum species number of LM and LV flocks) [10].

Using the older calibration yields average diversification rates of 0.87 (C.I. 0.70 to 1.33) and 0.90 (C.I. 0.73 to 1.37) respectively.

If clades have different peak periods of diversification, even though average diversification rates are relatively similar among tribes, this would suggest that biological differences among tribes did matter in the build-up of present-day diversity.

With a known diversity of 361 modern species (Table 1) and an estimated basal split at 157 Myr ago, the Lophiiformes exhibit an average net diversification rate of 0.0368 event per lineage per million years under d:b = 0 and 0.0181 event per lineage per million years under d:b = 0.95.

We used models assuming constant per lineage rates of speciation and extinction to estimate average net diversification rates (speciation rate minus extinction rate) for the LT flock and constituent clades (Table S2) [32].

Therefore, we believe the GAMs are fitting real features of the distribution of node ages in our sample: the average overall decline in diversification rate is largely due to decline from intermediate to recent periods, which encompass most of the nodes contributing information to the test statistics.

The average per-lineage species diversification rate for the C. salviifolius lineage was 1.46 2.44 species per million years.

Here we investigate two possible causes of fast early rates: change in average body size or diversification rate of deep metazoan lineages.

The new timetree obtained for Magnoliidae in this study allowed us to detect an average of nine significant diversification rate shifts across lineages, implying that diversification has not been a homogeneous process throughout the history of the clade.

In addition to those five main shifts, the net diversification rate averaged over the sample of 1000 trees show a general increase both within the Laurales and within the Magnoliales.
