After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.

经过二簇检验、分枝长度检验和相对速率检验,删除2条速率不恒定的序列后,用剩余的13条序列,以鸡形目与雁形目的分歧时间(89.8MYA)为锚定点,用顺序标定法标定鸭科鸟类分子钟的分析结果表明,用&1+2TiTv&分析得到的鸭科鸟类的分歧时间比较可靠;氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致,表明氨基酸序列更适合用于鸭科鸟类分子钟的研究;用同一基因标定分子钟时,较长序列得到的结果标准误比较小;与核苷酸序列相比,氨基酸序列更适于用作分子钟的标定。

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340~1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230~2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ~20and the lake returned to high level during 2330~930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.
