| Abstract |
Changes in geology, sea-level and climate are hypothesised to have been major driving processes of evolutionary diversification (speciation and extinction) in the Australo-Papuan region. Here we use complete species-level sampling and multilocus (one mitochondrial gene, five nuclear loci) coalescent analyses to estimate evolutionary relationships and test hypotheses about the role of changes in climate and landscape in the diversification of the Australo-Papuan butcherbirds and allies (Cracticinae: Cracticus, Strepera, Peltops). Multilocus species trees supported the current classification of the morphologically, ecologically and behaviourally divergent Australian Magpie (Cracticus tibicen (previously Gymnorhina tibicen)) as a member of an expanded genus Cracticus, which includes seven other species with 'butcherbird' morphology and behaviour. Non-monophyly of currently recognised species within Peltops and the white-throated butcherbird species-group (C.argenteus, C.mentalis, C. torquatus) at both mtDNA and nuclear loci suggest that a comprehensive taxonomic revision is warranted for both of these groups. The time-calibrated multilocus species tree revealed an early divergence between the New Guinean rainforest-restricted Peltops lineage and the largely open-habitat inhabiting Cracticus (butcherbirds and magpies) plus Strepera (currawongs) lineage around 17-28Ma, as well as a relatively recent radiation of lineages within Cracticus over the past 8Ma. Overall, patterns and timings of speciation were consistent with the hypothesis that both the expansion of open sclerophyllous woodlands 25-30Ma and the formation of extensive grassland-dominated woodlands 6-8Ma allowed the radiation of lineages adapted to open woodland habitats. |

Attention Score in Context
This research output has an Altmetric Attention Score of 25. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 November 2021.
All research outputs
#1,549,921
of 25,374,917 outputs
Outputs from Molecular Phylogenetics & Evolution
#228
of 4,836 outputs
Outputs of similar age
#12,916
of 286,270 outputs
Outputs of similar age from Molecular Phylogenetics & Evolution
#4
of 57 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,836 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.4. This one has done particularly well, scoring higher than 95% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 286,270 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 95% of its contemporaries.
We're also able to compare this research output to 57 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 92% of its contemporaries.
