Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing

open access: yesAnimal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...
