Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The Yucatan Peninsula (YP) suffered several marine transgressions and regressions during the Quaternary, thus molding the distribution of its present biota, especially its freshwater fish fauna. The Mayan cichlid (Mayaheros urophthalmus Günther) is a euryhaline fish native to the Atlantic slope of Mexico and northern Central America, including the YP; it is one of the most widespread freshwater species in the region. Herein we discuss a phylogeographic scenario by which the Mayan cichlid may have reached its current distribution in the YP. A Bayesian analysis and minimum spanning network were inferred from two partial mitochondrial genes, Cytochrome b (CYTB) and Cytochrome c Oxidase I (COI). The two fragments showed genetic differentiation among populations (Fst = 0.31, p value <0.001). Tajima’s D and Fu ´s F revealed a tendency to the expansion of some populations. A consistent ordination of north vs south populations was observed. A spatial analysis of molecular variance (SAMOVA) was performed to recognize putative barriers among populations of M. urophthalmus. A secondary molecular calibration located the window time in which the dispersal event may have occurred during the Pleistocene, around 1 Mya. We determined that a Quaternary dispersal around the old coastlines from the south explains the current distribution of the Mayan cichlid.
