Effects of Food Changes on Intestinal Bacterial Diversity of Wintering Hooded Cranes (<i>Grus monacha</i>)
As food is recognised as an important factor affecting the intestinal microbiota, seasonal changes in diet can influence the community composition. The hooded crane (<i>Grus monacha</i>) is an endangered migratory waterbird species, with some of the population wintering in the sallow lak...
