Isotopic niche partitioning between two apex predators over time by Drago, Massimiliano, Cardona, Luis, Franco Trecu, Valentina, Crespo, Enrique Alberto, Vales, Damián Gustavo, Borella, Florencia, Zenteno, Lisette, Gonzáles, Enrique M., Inchausti, Pablo

“…Stable isotope analyses have become an important tool in reconstructing diets, analyzing resource use patterns, elucidating trophic relations among predators and understanding the structure of food webs.<br />2. Here, we use stable carbon and nitrogen isotope ratios in bone collagen to reconstruct and compare the isotopic niches of adult South American fur seals (Arctocephalus australis; n = 86) and sea lions (Otaria flavescens; n = 49) ?…”
