Figure 3From: Effects of variation in food resources on foraging habitat use by wintering Hooded Cranes (Grus monacha) Effect of food characteristics on the relative abundance and density of Hooded Cranes within the Shengjin and Caizi lakes wetlands. a and d show a positive and significant linear relationship of both the relative abundance and density with food abundance (r > 0.5, p < 0.05); b, c, e and f show that the negative but not significant linear relationship both of the relative abundance and density with the food depth and sediment penetrability (r < 0.5, p > 0.05).Back to article page
