Spatial and temporal variations in stable carbon isotope ratios (i.e., δ13C) of primary producers are common but poorly understood features of isotopic characterizations of aquatic food webs. I invest...
The effect of water velocity on stable carbon and nitrogen isotope signatures of periphyton
water velocity stable carbon nitrogen isotope signatures
