TL;DR: A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.

TL;DR: This paper found that photographs with animal subjects were more numerous than those with plant subjects; they also represented a greater diversity of animals and had a higher instance of repetition than did plant photographs, and a significant naming disparity: animal photographs were three times more likely to be provided with a specific label (common name) than were plant photographs.

TL;DR: The authors analyzed two nationally-syndicated elementary science textbook series to explore their presentation of plant and animal content and found that the amount of animal content was greater than plant content in each series.

TL;DR: Evidence is found for the influence of past glaciations and glacial refugia on the patterns of pteridophyte diversity, that moisture availability and cold temperatures are strongly correlated with patterns of genus richness, phylogenetic diversity, and phylogenetic endemism, and it is infer that the topographic complexity of the region may be driving the assembly of the pteridine flora indirectly by influencing climate and precipitation patterns.
