CALIBRATION AGE AND QUARTET DIVERGENCE DATE ESTIMATION

  title={CALIBRATION AGE AND QUARTET DIVERGENCE DATE ESTIMATION},
  author={Christopher A. Brochu}
}
The date of a single divergence point—between living alligators and crocodiles—was estimated with quartet dating using calibrations of widely divergent ages. For five mitochondrial sequence datasets, there is a clear relationship between calibration age and quartet estimate—quartets based on two relatively recent calibrations support younger divergence estimates than do quartets based on two older calibrations. Some of the estimates supported by young quartets are impossibly young and exclude…

Did crocodiles become secondarily ectothermic ? : a paleohistological approach
TLDR
The results show that the last common ancestor of archosaurs was likely an endotherm, and that modern crocodiles became secondarily ectothermic, probably in response to their aquatic environment.
The resurrection of oceanic dispersal in historical biogeography.

TLDR
The resurrection of oceanic dispersal is the most striking aspect of a major shift in historical biogeography toward a more even balance between vicariance and dispersal explanations and implies that biotas are more dynamic and have more recent origins than had been thought previously.
Comparison of Serum Phospholipase A2 Activities of All Known Extant Crocodylian Species
TLDR
Serum samples from all 23 extant crocodilian species were tested for phospholipase A2 activity against nine different bacterial species and revealed that the three lineages of crocodilians exhibited PLA2 activities toward nine species of bacteria that were statistically distinguishable.
The Coccidia (Apicomplexa) of the Archosauria (Crocodylia: Eusuchia) of the World.
TLDR
Information is summarized on the 16 species of apicomplexans that are considered to be valid, including 8 Eimeria, 1 Haemogregarina, 4 Hepatozoon, 2 Isospora, and 1 Progarnia species, to provide a foundation for future research between parasitologists and herpetologists on parasitism of all reptiles and their relatives.
Flying rocks and flying clocks: disparity in fossil and molecular dates for birds
TLDR
Empirical patterns observed here suggest systemic overestimates for shallow nodes in existing molecular divergence dates for birds, and underlying biases that may drive these patterns are discussed.
