| Abstract |
We examine phylogeographic structure across a wide-ranging microhylid frog (Gastrophryne carolinensis) using both mitochondrial (mtDNA) and nuclear (AFLP) data. Species with similar ecological characteristics such as large range size, low vagility, or existence across known biogeographic barriers, often are comprised of multiple, cryptic lineages. Surprisingly, our analyses of both portions of the genome show very little phylogeographic or population genetic structure. The family Microhylidae is one of the largest families of anurans with over 60 genera and around 400 species distributed across much of the world (Americas, Asia, Africa, and Madagascar), but very few phylogeographic studies have assessed intraspecific genetic diversity across the mitochondrial and nuclear genomes. Our results suggest that G. carolinensis, one of only three species of microhylid native to the US, has experienced a severe population bottleneck with subsequent range expansion. Comparable molecular data from closely related microhylids, in addition to demographic and ecological analyses, will provide valuable insight into patterns of genetic diversity and the processes driving phylogeographic diversity in these wide-ranging frogs. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 29 April 2022.
All research outputs
#7,453,479
of 22,786,691 outputs
Outputs from Genetica
#144
of 713 outputs
Outputs of similar age
#28,449
of 81,910 outputs
Outputs of similar age from Genetica
#2
of 6 outputs
Altmetric has tracked 22,786,691 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 713 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 45th percentile – i.e., 45% 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 81,910 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
