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
Resumen El pasto lobero (Muhlenbergia phleoides [Kunth] Columbus) es un recurso forrajero nativo del norte de México; sin embargo, se desconoce su variabilidad en cuanto a atributos forrajeros. El objetivo de este estudio fue caracterizar la variabilidad morfológica y nutricional de 30 poblaciones de pasto lobero del estado de Chihuahua. La caracterización se realizó el segundo año de establecimiento a través de las variables morfológicas y nutricionales. Los datos morfológicos se analizaron con técnicas multivariadas. Para los datos nutricionales se realizó análisis de varianza y comparación de medias Tukey. Los tres primeros CP (componentes principales) explicaron el 82.38% de la variación total. El análisis de conglomerados jerárquicos identificó cuatro grupos. En el análisis nutricional, las poblaciones solo presentaron diferencias (p < 0.05) en la variable PC. La variabilidad que presentó el pasto lobero permite inferir que existe diversidad morfológica entre poblaciones del estado de Chihuahua; no obstante, las variables nutricionales no presentaron diferencia entre las poblaciones de esta especie.
