Unraveling reticulate evolution in North American Dryopteris (Dryopteridaceae).
Sessa EB, Zimmer EA, Givnish TJ. Sessa EB, et al. BMC Evol Biol. 2012 Jun 30;12:104. doi: 10.1186/1471-2148-12-104. BMC Evol Biol. 2012. PMID: 22748145 Free PMC article.
BACKGROUND: The thirteen species of Dryopteris in North America have long been suspected of having undergone a complicated history of reticulate evolution via allopolyploid hybridization. ...Allohexaploid D. clintoniana appears to be derived from D. cristata x D.gol …

Historical bottlenecks decrease genetic diversity in natural populations of Dryopteris cristata.
Landergott U, Holderegger R, Kozlowski G, Schneller JJ. Landergott U, et al. Heredity (Edinb). 2001 Sep;87(Pt 3):344-55. doi: 10.1046/j.1365-2540.2001.00912.x. Heredity (Edinb). 2001. PMID: 11737281
The reconstruction of recent historical population sizes allowed us to investigate the influence of random evolutionary processes on present-day genetic diversity in populations of Dryopteris cristata. This long-lived, allotetraploid fern is rare and endangered in t …

Reconstructing Dryopteris "semicristata" (Dryopteridaceae): Molecular profiles of tetraploids verify their undiscovered diploid ancestor.
Stein DB, Hutton C, Conant DS, Haufler CH, Werth CR. Stein DB, et al. Am J Bot. 2010 Jun;97(6):998-1004. doi: 10.3732/ajb.0900355. Epub 2010 May 21. Am J Bot. 2010. PMID: 21622469 Free article.
The identity of a parent shared by two tetraploid species in the cosmopolitan fern genus Dryopteris has remained elusive for more than 50 years. Based on available data, four hypotheses were developed previously, each providing a different resolution to this uncertainty. . …
