The paper analyzes molecular data from historical herbarium specimens and modern samples to assess the status of Azolla species in California, finding potential extirpation of Azolla microphylla.

The paper examines how coastal fog exposure affects epiphytic cryptogam communities and finds little variation in abundance, reproduction, and community composition despite strong microclimate differences.

The paper uses off-target metagenomics to analyze bacterial communities associated with the liverwort Calasterella californica using whole genome sequencing data.

The paper analyzes genetic diversity and demographic history of Azolla populations in California, identifying three groups and finding evidence of recent invasions for two newly reported taxa.

The paper presents a chromosome-level genome assembly of Azolla caroliniana, improving upon previous assemblies and aiding in understanding its population genetics and taxonomy.

The paper characterizes the microbiome of the nitrogen-fixing fern Azolla, revealing multiple endosymbionts with varying transmission modes and stages of symbiosis evolution.
