The allopatric model of biological speciation involves fracturing of a pre-existing species distribution and subsequent genetic divergence in isolation. Accumulating global evidence from the Pyrénées, Andes, Himalaya, and the Southern Alps in New Zealand shows the Pleistocene to be associated with the generation of new alpine lineages. By synthesising a large number of genetic analyses and incorporating tectonic, climatic, and population-genetic models, we show here how glaciation is the likely driver of speciation transverse to the Southern Alps. New calibrations for rates of molecular evolution and tectonic uplift both suggest a ∼2 million-year (Ma) time frame. Although glaciation is often seen as destructive for biodiversity, here we demonstrate its creativity, and suggest a general model for speciation on temperate mountain systems worldwide.
This research output has an Altmetric Attention Score of 65. 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 10 May 2022.
All research outputs
#752,345
of 28,731,329 outputs
Outputs from Trends in Ecology & Evolution
#408
of 3,447 outputs
Outputs of similar age
#12,336
of 312,385 outputs
Outputs of similar age from Trends in Ecology & Evolution
#6
of 42 outputs
Altmetric has tracked 28,731,329 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 97th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,447 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 31.3. This one has done well, scoring higher than 88% 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 312,385 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 96% of its contemporaries.
We're also able to compare this research output to 42 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 85% of its contemporaries.
