Global mitochondrial DNA phylogeography and population structure of the silky shark, Carcharhinus falciformis

Summary: This genetic study investigates the global population structure of silky sharks
using mitochondrial DNA sequence data from multiple ocean basins. The analysis identifies
strong genetic differentiation between Atlantic and Indo-Pacific populations, supporting the
hypothesis of limited female-mediated gene flow and regional management units. The results
underscore the vulnerability of silky sharks to region-specific threats and call for international
coordination in the implementation of conservation and fisheries management measures
based on robust genetic evidence.
