| Abstract |
Genome-wide signatures of convergent evolution are widely expected but rarely revealed in animals. Subterranean rodent genome and transcriptome data produced by next-generation sequencing facilitate the use of phylogenetic methods to infer non-synonymous and synonymous substitution rates within coding regions, which can reveal changes at the molecular level that are correlated with the dramatic shift from a terrestrial to subterranean habitat. Our study used previously sequenced genome or transcriptome data of two subterranean rodents, the blind mole rat and naked mole rat, and their terrestrial relatives, the mouse and guinea pig, to investigate the genetic basis of rodent subterranean adaptation. An analysis of 4996 orthologous genes revealed that the substitution pace of coding sequences was significantly slower in the blind mole rat than in the mouse, and slower in the naked mole rat than in the guinea pig. The dN/dS ratio was significantly higher in the blind mole rat than in the mouse and in the naked mole rat than in the guinea pig. These patterns are most likely related to the longer generation time and lower effective population size of subterranean rodents caused by subterranean ecological constraints. We also identified some genes and gene ontology (GO) categories that might be candidates for adaptation to subterranean life. Our study reveals a case of subterranean convergent evolution in rodents that is correlated with change in the pace and mode of molecular evolution observed at the genome scale. We believe that this genomic signature could have also evolved in other cases of subterranean convergence. Additionally, the genes that displayed the most radical changes in their patterns of evolution and their associated GO categories provide a strong basis for further comparative and functional studies, and potentially reveal molecular signatures of adaptation to subterranean life. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 26 December 2015.
All research outputs
#16,722,190
of 25,374,917 outputs
Outputs from BMC Ecology and Evolution
#2,818
of 3,714 outputs
Outputs of similar age
#227,716
of 394,040 outputs
Outputs of similar age from BMC Ecology and Evolution
#57
of 78 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,714 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.5. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
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 394,040 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 78 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
