DOI:
doi:10.5061/dryad.2q3k2
摘要:
ant on calibration, traditionally based on fossil constraints on clade (node) ages. Tip calibration has been developed to obviate undesirable aspects of node
Data from: Proxies in practice: calibration and validation of multiple indices of animal abundance

摘要:
. We tested our calibration methods using leave-one-out cross validation and simulation. Our cross-validation analysis did not definitively identify a single
Data from: The impact of fossil stratigraphic ranges on tip?calibration, and the accuracy and precision of divergence time estimates

摘要:
The molecular clock provides the only viable means of establishing realistic evolutionary timescales but it remains unclear how best to calibrate
Data from: Testing the impact of calibration on molecular divergence times using a fossil-rich group: the case of Nothofagus (Fagales)

Nothofagus;age constraints;fossil record;Fagales;molecular dating;confidence intervals;calibration;relaxed molecular clock
DOI:
doi:10.5061/dryad.qq106tm4
摘要:
Although temporal calibration is widely recognized as critical for obtaining accurate divergence-time estimates using molecular dating methods, fe
Data from: Geomolecular dating and the origin of placental mammals

Placentalia;Cretaceous-Paleogene boundary;Paleogene;Mammalia;Life history;molecular dating;Cretaceous;Evolutionary Rate;Fossil calibration
DOI:
doi:10.5061/dryad.s43f8
摘要:
dating errors at specific nodes unfortunately tends to transfer underlying rate errors to adjacent branches. Thus, tight calibration across the tree
Data from: A stochastic rate-calibrated method for time-scaling phylogenies of fossil taxa
负责人:
关键词:
comparative method;node dating;Cladistics;divergence times;fossil record;Simulation;Macroevolution;phylogenetics;time-scaling
DOI:
doi:10.5061/dryad.vk7t0
摘要:
time-scaling method must be calibrated with explicit estimates of three rates: branching, extinction and sampling, and thus is named the cal3 ti
Data from: Late-glacial demographic expansion motivates a clock overhaul for population genetics
