Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing. [PDF]
Anim GenetABSTRACT 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 ...

Reproductive biology, distribution and abundance of Squalus megalops (Macleay, 1881) and Squalus mitsukurii (Jordan & Snyder, 1903) off southern Brazil, southwest Atlantic. [PDF]
J Fish BiolAbstract Squalus megalops and Squalus mitsukurii are recognized as the most abundant Squalus species in the southern Brazil region. Currently, S. megalops is listed as ‘least concern’ (LC) and S. mitsukurii as ‘endangered’ (EN). However, at the regional level, both species are classified as ‘data deficient’ – DD, due to the lack of population local ...
