Summary: This study compiles and updates the checklist of ferns and lycophytes from the Sierra Madre Occidental (SMOc). Our updated list includes 312 species, of which 276 are ferns and 36 are lycophytes integrated into 27 families and 75 genera. The richest families are Pteridaceae (118), Polypodiaceae (31), Selaginellaceae (30), Aspleniaceae (25), and Dryopteridaceae (25).

Summary: Vietnam has a rich biodiversity, with over 13,500 species of vascular plants. Despite the advancements in molecular phylogenetics, the classification of vascular plants in Vietnam has not been updated according to modern classification systems. This paper provides a historical overview of the classification of vascular plants in Vietnam, compares different classification systems, and establishes a foundation for future research and plant collections.

Summary: This study investigates the substrate preferences of ferns and lycophytes, finding substantial intraspecific variation and proposing a new concept of gradual differences in habitat preferences. The findings have immediate implications for ecological and evolutionary studies and may significantly impact plant research in general.

Summary: This study provides a phylogenetic framework for PEBP genes and investigates their expression patterns in selected lycophytes and ferns. The results indicate that PEBP genes are involved in reproductive transitions and spore production in these plants, suggesting their important roles in meristem maintenance and sporangium development.

Summary: Detailed studies of fungi associated with lycophytes and ferns provide crucial insights into the early evolution of land plants. Most investigations have relied on visual root inspection, but this research establishes and evaluates a metabarcoding protocol to analyze fungal communities using two primer pairs. The results demonstrate the reliability of the ITS-based approach for analyzing fungal communities and suggest the 18S approach is more suitable for studying arbuscular mycorrhizal fungi.

Summary: Gujarat, the westernmost state of India, is known for its diverse climatic conditions ranging from semi-arid to pure desert environments. Previous studies on pteridophyte diversity in Gujarat were lacking, with only 12 genera and 16 species reported. This investigation documented a total of 50 naturally occurring species and 13 cultivated species, with new distributional records for the state. The study revealed the highest diversity in south Gujarat, followed by Central Gujarat and the Saurashtra region, with lower diversity in the North and Kachchh regions.

Summary: Rotuma Island, located about 580 km north of the main archipelago of Fiji, is politically part of Fiji but has distinct cultural and floristic differences. The island is home to 37 native and 3 naturalised pteridophyte species, with original vegetation pockets and substantial areas of secondary forest still existing despite human activity. There is potential for the discovery of more pteridophyte species on Rotuma, with unique native species not found elsewhere in Fiji.

Summary: The study found that there are variations in the definitions of quarantine within the US prison systems, with most states not aligning with all CDC recommendations. Only a few states provide quarantine data, highlighting the need for standardization of definitions and transparency in data reporting to better understand the effectiveness of quarantine practices in mitigating COVID-19 outbreaks in carceral settings.

Summary: This study investigates the regulation extent of CO2 assimilation in the lycophyte Selaginella martensii under different light regimes, revealing acclimation plasticity similar to seed plants but with inherently low photosynthetic capacity. Specific modulations of stomatal density, chloroplast surface area, and cell wall thickness improved CO2 diffusion, but the carboxylation rate was less effectively upregulated, leading to a greater incidence of biochemical limitations of photosynthesis. The lycophyte prevents potential photodamage to the chloroplast by diverting a large fraction of photosynthetic electrons to sinks alternative to carboxylation due to its low carboxylation capacity.

Summary: Climate plays a more important role than soil in predicting species and trait composition in both forest layers, with the understorey being more vulnerable to climate impacts. The overstorey is more influenced by soil, likely driven by deciduous species.

Summary: This study investigated the deep phylogenetic relationships within Polypodiaceae by utilizing 81 plastid genomes, improving the resolution of backbone phylogeny. The research identified potential phylogenetic artefacts affecting the incongruence of phylogenetic inferences and provided a robust framework for future subfamilial taxonomy within Polypodiaceae.

Summary: The study found that WhatsApp users in Brazil are willing to correct COVID-19 misinformation, with a focus on providing corrections to groups and senders. Users with lower education levels and younger age groups are less inclined to offer corrections. Perceived severity of COVID-19 and the ability to critically evaluate messages positively influence correction behaviors.

Summary: The study utilizes various molecular techniques to reveal the significant role of hybridization and high polyploidy in lycophytes. It shows that hybridization is easily achieved between different species, with bidirectional crosses occurring between identical cytotypes. Fertile allopolyploids may have formed repeatedly from sterile homoploid and interploid hybrids.

Summary: Comprising the majority of extant fern species diversity, Polypodiales are believed to have originated in the Late Cretaceous. Divergence time estimates utilizing plastome data and fossil constraints support the origin of Polypodiales and its closest relatives in the Triassic, major lineages established in the Jurassic.
