谱系地理学中的巢式支系分析法请教 已有1人参与

最近在进行templton的巢式分析时，对geodis计算结果进行检索，检索表中有几句话极端晦涩难懂，请高手翻译一下。 4. Are both of the following conditions satisfied? a. The clades (or 2 or more subsets of them) with significantly small Dc or Dn values have ranges that are completely or mostly non-overlapping with the other clades in the nested group (particularly interiors). b. The pattern of completely or mostly non-overlapping ranges in the above condition represents a break or reversal from lower level trends within the nested clade series (applicable to higher-level clades only). 16. Is the species present in the intermediate geographical areas that were not sampled? • YES - Go to step 18. • NO - Allopatric Fragmentation. If inferred at a high clade level, additional confirmation occurs if the clades displaying restricted by at least partially non overlapping distributions are mutationally connected to one another by a larger than average number of steps. |
