Metric Options: CountsSelecting 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
Of 7 dissected dung balls of the extinct Shasta ground sloth (Edentata) from Rampart Cave, Arizona, 4 (57%) were found to contain nematode juveniles, helminth eggs, and/or coccidian oocysts. One dung ball was radiocarbon dated at 10,500 ± 180 yr, about the time of ground sloth extinction. It is supposed that the parasites also are extinct. Agamofilaria oxyura n. sp. is proposed for first-stage juveniles of an oxyurid. These juveniles measured 13-20 x 126-198 (16.8 x 159) μm. Strongyloides shastensis n. sp. is reported as first-stage juveniles, some of which clearly are molting. These juvenile worms were 23-27 x 270-345 (24.4 x 305.3) μm. Operculated schistosome-like eggs, each with an abopercular point, were 33-50 x 63-90 (43.0 x 81.9) μm. A second type of object that resembled a helminth egg had a thick wall and was 11-14 x 13-18 (13.5 x 15.5) μm. A new collective genus, Archeococcidia, is proposed to include 2 new fossil oocysts. Archeococcidia antiquus n. sp. was the most abundant form found. Its unsporulated oocysts were 19-21 x 21-23 (19.6 x 22.1) μm, and its outer wall bore punctations. Unsporulated oocysts of Archeococcidia nothrotheriopsae n. sp. were spheroidal, 31-35 (33.8) μm wide, and had a smooth outer surface
