    • A drought-driven model for the evolution of obligate apomixis in ferns: evidence from pellaeids (Pteridaceae). 

      Grusz, Amanda L; Windham, Michael D; Picard, Kathryn T; Pryer, Kathleen M; Schuettpelz, Eric; Haufler, Christopher H (American journal of botany, 2021-02-23)
      <h4>Premise</h4>Xeric environments impose major constraints on the fern life cycle, yet many lineages overcome these limitations by evolving apomixis. Here, we synthesize studies of apomixis in ferns and present an evidence-based ...

    • Abrupt deceleration of molecular evolution linked to the origin of arborescence in ferns. 

      Korall, Petra; Schuettpelz, Eric; Pryer, Kathleen M (Evolution; international journal of organic evolution, 2010-09)
      Molecular rate heterogeneity, whereby rates of molecular evolution vary among groups of organisms, is a well-documented phenomenon. Nonetheless, its causes are poorly understood. For animals, generation time is frequently ...

    • DNA barcoding exposes a case of mistaken identity in the fern horticultural trade. 

      Pryer, Kathleen M; Schuettpelz, Eric; Huiet, Layne; Grusz, Amanda L; Rothfels, Carl J; Avent, Tony; Schwartz, David; ... (8 authors) (Molecular ecology resources, 2010-11)
      Using cheilanthoid ferns, we provide an example of how DNA barcoding approaches can be useful to the horticultural community for keeping plants in the trade accurately identified. We use plastid rbcL, atpA, and trnG-R sequence ...

    • Ferns diversified in the shadow of angiosperms. 

      Schneider, Harald; Schuettpelz, Eric; Pryer, Kathleen M; Cranfill, Raymond; Magallón, Susana; Lupia, Richard (Nature, 2004-04)
      The rise of angiosperms during the Cretaceous period is often portrayed as coincident with a dramatic drop in the diversity and abundance of many seed-free vascular plant lineages, including ferns. This has led to the widespread ...

    • Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences. 

      Pryer, Kathleen M; Schuettpelz, Eric; Wolf, Paul G; Schneider, Harald; Smith, Alan R; Cranfill, Raymond (American journal of botany, 2004-10)
      The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages. Despite considerable progress in our understanding of fern relationships, ...

    • The Evolution and Diversification of Epiphytic Ferns 

      Schuettpelz, Eric (2007-05-03)
      Leptosporangiate ferns, with more than 9000 extant species, are truly exceptional among the non-flowering lineages of vascular plants. However, this rather remarkable diversity was not simply a consequence of being able ...
