Are lowland rainforests really evolutionary museums? Phylogeography of the green hylia (Hylia prasina) in the Afrotropics.

摘要: A recent trend in the literature highlights special role that tropical montane regions and habitat transitions peripheral to large blocks of lowland rainforest play diversification process. The emerging view is one rainforests as evolutionary ‘museums’; where biotic diversity maintained over time, additional accrued from areas, but there has been little diversification. This leads prediction genetic without geographic structure widespread taxa. Here, I assess notion ‘museum’ with a phylogeographic study green hylia (Aves: Sylviidae: Hylia prasina) using 1132 bp mtDNA sequence data. distribution within mainland subspecies reveals five highly divergent haplotype groups distributed accordance broad-scale areas endemism Afrotropics. pattern currently described refutes characterization forests museums. If variation occurs broadly species, conservation policy makers may need rethink their priorities for
