Fig. 4: Evidence for increasing prevalence of eDNA studies monitoring vertebrates over time.
From: eDNA offers opportunities for improved biodiversity monitoring within forest carbon markets
The x-axis in both graphs represents the year published, while the y-axis is the percent of eDNA studies analyzed. The left panel shows the empirical % of eDNA studies involving vertebrates in different year intervals (sample size shown in gray at the base of each bar). The right panel shows the model-predicted values along with 95% confidence intervals (error bars) from a binomial (logistic) GLM model describing the increase.
