Figure 3From: Climate-driven diversification in two widespread Galerida larksMedian-joining networks. They were obtained using the short -291 bp- cytochrome b fragment. Each circle represents one haplotype, and its size is proportional to its frequency (see Tables 4–5). Branch length is proportional to number of mutations. 3a) crested lark. 3b) Thekla lark.Back to article page
