Sentence examples for a decreasing in diversification from inspiring English sources

Both models, nonetheless, predict a decreasing in diversification rates through time.

The γ statistic has been used as an objective way to infer a decrease in diversification rate.

Here, I examine whether detection of a decrease in diversification rates using γ necessarily requires that a high rate of diversification occurred near the base of a tree.

A popular method for inferring a decrease in speciation rate, which might suggest an early burst of diversification followed by a decrease in diversification rate is the γ statistic.

A priori it would be expected that a decrease in diversification through time would reduce statistical bias and increase statistical power and an acceleration in lineage diversification through time would likely increase bias and reduce statistical power.

Despite these limitations, values ≤0.05 quantile of tree deviation captured lineages with lineages through time plots that are consistent with the expectation of early, rapid diversification followed by a decrease in diversification rate (Figure 1).

Incomplete lineage sampling can also affect the value of the γ statistic, here in a direction that favors the hypothesis of a decrease in diversification rate, interpreted as equivalent to an early burst.

The Late Cretaceous and Paleocene are characterized by a decrease in diversification rates.

On the other hand, TreePar detected a decrease in diversification rates at 7.8 Ma, and an increase at 3.2 Ma for the model allowing two shifts.

TreePar detected a decrease in diversification rates at 7.8 Ma, and MEDUSA estimated high relative extinction rates in Cheirolophus, prior to the rate shift within the Canarian radiation.

In gymnoperms, the best model was one with a rate shift occurring ca. 154 Ma, corresponding to a decrease in diversification during a cool climate mode (Table 2, Figure 1A).
