WebApr 24, 2024 · Here, we explore the power of a Bayesian Birth‐Death Skyline (BDSKY) model to detect the signature of MEEs through changes in extinction rates under a “time‐slice” approach. In this approach, MEEs are time intervals where the extinction rate is greater than the speciation rate. WebOct 1, 2016 · The birth–death–skyline process still makes a number of limiting assumptions, in particular that all species are assumed to be indistinguishable, hence all have the same speciation and extinction rates and the same probabilities of being sampled at any given time. daniel tiger\u0027s neighborhood songs archiveWebMar 1, 2024 · In addition to the coalescent-based models, birth-death skyline (BDSKY v1.4.3) models implemented in the BEAST v2.5.1 ( Bouckaert et al., 2014) were also employed to study the A (H1N1)pdm09 viral transmission potential during the pandemic waves across various geographic regions. daniel tiger\\u0027s neighborhood tea party game
