Description

Tropical elasmobranchs could play significant roles in connecting coastal and river ecosystems, yet few studies have explored the trophic ecology of elasmobranch species that may link these biomes. We investigated the trophic niches of 7 such species in northern Australia during the tropical monsoonal wet and dry seasons, using stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopes (SI), and fatty acid (FA) biomarkers taken from muscle tissue. Both SI and FA metrics suggested significant niche...[Show more]
