These data accompany the paper "Dietary specialization among individual squid: using Illex argentinus as a case and meta-analysis for other squid species" by Lin, D.M, Zang, N., Song, W., Punt, A.E., Gong, Y., Li, G., and Chen, X.J.. data.csv and env.csv files contains data that were used to estimate the dietary specialization among individual squid and quantify the potential drivers of individual dietary specialization. The R codes used to analyze the dietary specialization of individual squid are included in the .R files.
