Fig. 2From: Influences of submerged plant collapse on diet composition, breadth, and overlap among four crane species at Poyang Lake, Chinaa Species-based and b sample-based rarefaction curves. The species- and sample-based rarefaction curves, built by randomly resampling sequences and samples respectively at increasing levels of accumulation, indicate whether the sequencing depth and sampling size were sufficient to characterize the diversity of dietary items. The colors of the curves correspond to the crane species: blue: Siberian Crane; purple: White-naped Crane; green: Hooded Crane; and red: Eurasian CraneBack to article page
