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
New information on the taxonomy, distribution and natural history of the lizards Mabuya berengerae and M. pergravis, as well as for the snake Coniophanes andresensis, are herein provided. These three endemic species of the San Andrés and Providencia islands are currently believed to be very rare or even extinct. Despite the short period of study on both islands, this contribution demonstrates that the lizards are not uncommon, as up to eight individuals were found each half an hour. According to the IUCN, the evaluation of the conservation status classifies M. berengerae and M. pergravis as near threatened (NT) and C. andresensis as critically endangered (CE). Their small geographic distribution, considerable anthropic impact and the effect of alien species could be the main causes that affect the population densities in C. andresensis. We found and corrected some inconsistencies in the taxonomic characters previously published for M. berengerae, a species currently known from the holotype. It is suggested to carry out basic research programs, conservation and educational initiatives, and efforts to protect their natural habitats on the islands.
