ABSTRACT The honeyeaters are the most species-rich clade of birds east of Wallace’s Line. They occupy a wide range of habitats, from desert to rainforest, and occur throughout Australia, New Guinea, and oceanic islands across Wallacea and the Pacific. Honeyeater natural history is well characterised, but comparative studies of this group are hampered by the lack of a well-supported phylogeny. Here, we infer the first genome-scale, genus-level phylogeny of the honeyeaters using 4397 ultraconserved elements from 57 species. We analysed the data using concatenated and species-tree approaches, and we found support for novel clades previously undetected in analyses of single- or multi-locus datasets. Despite sequencing thousands of loci, phylogenetic relationships of the New Caledonian Crow Honeyeater (Gymnomyza aubryana) remain equivocal. This study provides a new phylogenetic framework from which to study the ecology and evolution of one of Australasia’s most iconic avian clades.

超保守元素解决了澳大利亚主要鸟类辐射中的属级关系(Aves:Melipagidae)

摘要 食蜜鸟是华莱士线以东种类最丰富的鸟类。它们栖息在从沙漠到热带雨林的广泛栖息地,遍布澳大利亚、新几内亚以及横跨华莱士和太平洋的海洋岛屿。食蜜鸟的自然历史特征很好,但由于缺乏充分支持的系统发育,对该组的比较研究受到阻碍。在这里,我们使用来自 57 个物种的 4397 个超保守元素推断出蜜食动物的第一个基因组规模、属级系统发育。我们使用串联和物种树方法分析了数据,我们发现支持以前在单位点或多位点数据集分析中未检测到的新进化枝。尽管对数千个基因座进行了测序,但新喀里多尼亚乌鸦食蜜鸟 (Gymnomyza aubryana) 的系统发育关系仍然模棱两可。
