Research goals of special concern for Carcharhinus leucas (Carcharhiniformes: Carcharhinidae) in Latin America – biological, distributional, and conservation priorities

Neotropical Ichthyology
The bull shark (Carcharhinus leucas) is a coastal predator that relies on low salinity habitats (estuaries, rivers, lakes) for reproduction. Identifying inshore nurseries and parturition areas is critical to its conservation.

Size-based variation in intertissue comparisons of stable carbon and nitrogen isotopic signatures of bull sharks (Carcharhinus leucas) and tiger sharks (Galeocerdo cuvier) [PDF]

, 2010
Stable isotopes are important tools for understanding the trophic roles of elasmobranchs. However, whether different tissues provide consistent stable isotope values within an individual are largely unknown.
