fern-diversity
Fern diversity encompasses the study of the evolutionary, morphological, and ecological variation among ferns, one of the oldest and most species-rich groups of vascular plants. Understanding fern diversity provides critical insights into plant evolution, as ferns represent a key lineage that diverged before seed plants arose and have persisted through major extinction events. Research in this area informs conservation efforts and helps reveal how plants adapt to a wide range of environmental conditions across the globe.
