Effects of Small Hydropower Dam Removal on Food Web Structures in the Heishui River

Fishes
Following Yangtze River protection policies, many small dams have been removed. Using the Heishui River as an example, we compared food web structures among areas affected by dams (DAs), areas from which dams were removed (DRAs), and natural reference ...

Hydrogen isotope ratios in animal body protein reflect trophic level

, 2005
1Carbon and nitrogen isotope ratios in consumer tissues are known to correlate with diet isotope composition, and nitrogen isotope ratios are observed to increase with increasing trophic level.2We analysed nitrogen and hydrogen isotope ratios of collagen
