Transposon signatures: species-specific molecular markers that utilize a class of multiple-copy nuclear DNA.

abstract：:Understanding the processes that shape patterns of genetic structure across space is a central aim of landscape genetics. However, it remains unclear how geographical features and environmental variables shape gene flow, particularly for marine species in large complex seascapes. Here, we evaluated the genomic composi...
