A drought-driven model for the evolution of obligate apomixis in ferns: evidence from pellaeids (Pteridaceae).
(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 ... -
Unique expression of a sporophytic character on the gametophytes of notholaenid ferns (Pteridaceae).
(American journal of botany, 2012-06)PREMISE OF THE STUDY: Not all ferns grow in moist, shaded habitats; some lineages thrive in exposed, seasonally dry environments. Notholaenids are a clade of xeric-adapted ferns commonly characterized by the presence of ...
