Abstract

© The Author(s)., The canonical model of sex-chromosome evolution predicts that, as recombination is suppressed along sex chromosomes, gametologs will progressively differentiate, eventually becoming heteromorphic. However, there are numerous examples of homomorphic sex chromosomes across the tree of life. This homomorphy has been suggested to result from frequent sex-chromosome turnovers, yet we know little about which forces drive them. Here, we describe an extremely fast rate of turnover among 28 species of Ranidae. Transitions are not random, but converge on several chromosomes, potentially due to genes they harbour. Transitions also preserve the ancestral pattern of male heterogamety, in line with the ‘hot-potato’ model of sex-chromosome transitions, suggesting a key role for mutation-load accumulation in non-recombining genomic regions. The importance of mutation-load selection in frogs might result from the extreme heterochiasmy they exhibit, making frog sex chromosomes differentiate immediately from emergence and across their entire length., This work was primarily funded by two grants (31003A_166323 & CRSII3_147625) awarded by the Swiss National Science Foundation to N.P.

Abstract

Abstract: The superconductivity in Na0.3Co1−x M x O2 ·1.3H2O and the charge ordering in Na0.5Co1−x M x O2 have been investigated for M=Mn and Ti substitution for Co. Single-phased Na0.5Co1−x M x O2 (0⩽ x ⩽0.1, M=Mn, Ti) materials were prepared by Na deintercalation from Na0.75Co1−x M x O2; the hydrated Na0.3Co1−x M x O2 ·1.3H2O (0⩽ x ⩽0.1, M=Mn, Ti) materials were prepared by Na deintercalation and then water intercalation. Measurements of physical properties demonstrated that the superconductivity in Na0.3Co1−x M x O2 ·1.3H2O is evidently influenced by the Co-site doping and completely ceases at x =0.02 for Mn doping and x =0.01 for Ti doping. Analysis of resistivity and magnetization on Na0.5Co1−x M x O2 revealed that Mn doping has much stronger influence than Ti doping on both the charge ordering and the low-temperature physical properties.
