Map showing the geographicaldistribution of nest sites involved in eggshell membranes collection of the wild Crested Ibis in Yang County and Chenggu County, Hanzhong City, Shaanxi Province, central China.
Variation of δ¹³C (left) and δ¹⁵N (right) in eggshell membranes samples between mountains (red box) and plains (purple box). Significance between two habitat types are shown above the boxplot (***P < 0.001, **P < 0.05).
Isotopic niches based on eggshell membrane samples for wild Crested Ibis from mountain (red circle) and plain (purple triangle) habitats. Solid bold lines (ellipses) represent corrected standard ellipse area (SEA_c) showing the areas of isotopic niches. Black dotted lines represent the convex hull (total areas, TA) for all individuals. Each small circle and triangle represent the isotopic signature of a sample.
