Low Genetic Diversity and Complex Population Structure in Black Piranha (Serrasalmus rhombeus), a Key Amazonian Predator.

ABSTRACT: The black piranha (Serrasalmus rhombeus), a widely spread species in the rivers of the Amazon basin, plays a vital role as both key predator and important prey. Despite its essential contribution to ecosystem stability, there is a lack of information regarding its genetic diversity and population dynamics in the central Amazon region. As the Amazon continues to undergo environmental changes in the context of growing anthropogenic threats, such knowledge is fundamental for assist in the conservation of this species. This study is the first to analyze the genetic diversity and population structure of S. rhombeus in the central Amazon region using high-resolution genomic data. We employed a Genotyping-by-Sequencing approach with 248 samples across 14 study sites from various tri
