Conodonts and Carbon Isotopes during the Permian-Triassic Transition on the Napo Platform, South China

Carbon cycle perturbation expressed in terrestrial Permian–Triassic boundary sections in South China

Goethite, calcite, and organic matter from Permian and Triassic soils: Carbon isotopes and CO2 concentrations

Pedogenic goethites in each of two Early Permian paleosols appear to record mixing of two isotopically distinct CO2 components—atmospheric CO2 and CO2 from in situ oxidation of organic matter. The C values measured for the Fe(CO3)OH component in solid solution in these Permian goethites are 13.5‰ for the Lower Leonardian ( 283 Ma BP) paleosol (MCGoeth) and 13.9‰ for the Upper Leonardian ( 270 M...

Plankton and productivity during the Permian–Triassic boundary crisis: An analysis of organic carbon fluxes

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
