DOI: 10.1111/1755-0998.12660
Abstract: Despite advances that allow DNA sequencing of old museum specimens, sequencing small‐bodied, historical specimens can be challenging and unreliable as many contain only small amounts of fragmented DNA. Dependable methods to sequence such specimens are… read more here.

DOI: 10.1655/herpetologica-d-16-00053
Abstract: Abstract: Considerable difficulty has been associated with the taxonomy of the genus Graptemys (Map Turtles and Sawbacks) over the last 50 yr, likely attributable to the relatively recent divergence of lineages and morphological variation within… read more here.
