摘要

Age–abundance profile for the trematode, Dicrocoelium dendriticum in a population of elk sampled from 2009 to 2011 from Cypress Hills Park, Alberta. The solid line represents the negative binomial distribution model fit using maximum likelihood; the dashed lines represent the 95% confidence intervals.
