Abstract: Abstract The trophic discrimination factor (TDF) of nitrogen isotopes (15N/14N) within amino acids, between a stream‐dwelling dobsonfly larva (Protohermes grandis: Megaloptera; Corydalidae) and its diet (chironomid larvae), was determined in controlled feeding experiments. Last‐instar larvae… read more here.
