Influences of submerged plant collapse on diet composition, breadth, and overlap among four crane species at Poyang Lake, China

Table 3 The observed dietary niche overlap among the four crane species at Poyang Lake in the winters of 2017 and 2018. P (Obs < = null) and P (Obs > = null) indicate the tail probabilities for the observed index, which were lower and higher than the histogram of the simulated index, respectively. ^* represents P < 0.05, and ^** represents P < 0.01
