摘要: Mountain lions ( Puma concolor ) were once endemic across the United States. The Northeastern population of mountain has been largely nonexistent since early 1800s and was officially declared extinct in 2011. This regionally lion is Pennsylvania State University9s official mascot, where it referred to as 9Nittany Lion9. Our goal this study use recent methodological advances ancient DNA massively parallel sequencing reconstruct complete mitochondrial (mtDNA) genomes multiple Nittany Lions by sampling from preserved skins. effort part a broader Lion Genome project intended involve undergraduates bioinformatics research engage Penn community discussions about conservation biology extinction. Complete mtDNA genome sequences obtained five individuals. When compared previously published sequences, are not more similar each other than individuals Western U.S. Florida. Supporting previous findings, North American overall closely related those South America had lower genetic diversity. result emphasizes importance continued Florida prevent further regional extinctions.
