Summary: In this study, we investigated the monophyly of genera in the Gleicheniaceae family using extended sampling and genomic data. The results confirmed the monophyly of most genera, except for Sticherus. We also found that while most Gleicheniaceae genera originated during the Mesozoic, some genera showed diversification in the Neogene and Quaternary periods. Our findings suggest the importance of reticulation and polyploidy in this diversification process, and identify Rouxopteris and Stromatopteris as evolutionary relics.

Summary: This study introduces an automated pipeline for creating a continuously updated fern tree of life (FTOL) using DNA sequence data from GenBank. The pipeline combines whole plastomes and commonly sequenced plastid regions to obtain a high-resolution global fern phylogeny. By resolving synonyms using a curated reference taxonomy, the FTOL includes about 40% more species than previous global fern phylogenies. The FTOL and its associated datasets are available through a web portal and R packages, providing immediate access to the most up-to-date and comprehensive fern phylogeny.

Summary: This study conducted phylogenetic analyses of the family Hypodematiaceae, supporting its monophyly. It found that Leucostegia consists of two clades, while Hypodematium includes seven strongly supported clades or single-accession clades. The study also inferred the evolution of important morphological characters and proposed the latest Jurassic-earliest Cretaceous origin of the family and the Upper Cretaceous origin of the two genera, with Hypodematiaceae originating from East Asia.

Summary: A molecular phylogenetic analysis of the Japanese apogamous fern Dryopteris yakusilvicola and related species revealed that its origin is not a hybrid between D. sparsa var. sparsa and D. sabaei, but likely involves undetected species closely related to D. melanocarpa var. elegans and D. sabaei. Further analysis of additional species in the D. sparsa complex and more nuclear markers are needed to clarify the relationships within this complex.

Summary: Antrophyum is a large genus of vittarioid ferns that is most diverse in tropical Asia and the Pacific Islands, but is also found in other regions such as temperate Asia, Australia, tropical Africa, and the Malagasy region. A comprehensive phylogeny of the genus was reconstructed based on chloroplast markers, which allowed for investigating the evolution of the genus through morphology, systematics, and historical biogeography. The study identified four new species, provided insights into species delimitation, and recognized a total of 34 species in the genus. The biogeographical analysis revealed that the distribution of extant species was influenced by both ancient and recent dispersal events.

Summary: The aquatic fern Salvinia molesta D.S. Mitch is an invasive species that can have devastating effects on freshwater habitats. The lack of clarity surrounding its genomic composition and genetic diversity hampers eradication efforts. This research reveals that S. molesta has multiple divergent genotypes and its maternal progenitor is likely an undescribed or extinct species, indicating multiple origins of this hybrid. The observed genomic diversity has significant implications for successful management and biological control of this invasive species.

Summary: This study analyzed sequence data of the fern family Blechnaceae and found that the group originated in Eurasia in the late Cretaceous, and diversified mainly in the austral Pacific region during the Paleocene-Eocene Thermal Maximum. Long-distance dispersal is frequent and asymmetrical, with Australia and tropical America being major source areas; climate-mediated vicariance shaped current distributions.

Summary: A new fern species, Selliguea wusugongii, has been described from southeastern Xizang, China, distinguished by its long need-like fronds with extremely narrow laminae. It is most similar to some Malay selligueoid ferns in morphology, but differs in several characteristics such as scattered scales, frond length, and venation. Phylogenetic analysis supports its closest relationship with S. rhynchophylla, despite differences in morphological traits like frond size and sorus position.

Hypodematium eglandulosum is distinguished from similar species by its eglandular plants and 3-pinnatifid leaves. Aspidium chrysolepis, currently treated as a synonym of H. crenatum, should be recognized as a distinct species.

Summary: This study investigated the taxonomy of the crustose lichen genus Calvitimela using molecular phylogenetics and morphological observations. The results revealed evolutionarily old and deeply divergent lineages within Calvitimela, with overlapping morphological characters between different subgenera. Chemical characters were informative at the level of subgenera but often homoplastic at the species level. A practical taxonomy of Calvitimela was proposed based on these findings.

Summary: This study investigates the evolutionary history and speciation mechanisms of montane potamids in the Hengduan Mountains Region. The results suggest that the vicariance events of these crabs are correlated with the emergence of sky islands due to the uplift of the mountains. The mountain ridges provided corridors for their dispersal and past climatic conditions played a crucial role in their evolutionary history. The mechanisms isolating sky islands are reinforced by the climatic features of dry-hot valleys and continue to affect local diversification.

Summary: This study investigates the phylogenetic relationships among patellogastropod families using mitochondrial and phylogenomic data. The results show that the mitochondrial phylogeny recovers monophyly of most families, but the relationships among families are still contentious. However, a more robust family-level topology consistent with morphology is achieved by phylogenomics. Additionally, the mainly deep-water families are found to be monophyletic, suggesting a single colonization of the deep water during the Jurassic.

Summary: Despite numerous studies on hybrid speciation, our understanding of this process remains limited. In this study, we conducted an 18-year systematic investigation on Populus taxa on the Qinghai-Tibet Plateau and discovered three new taxa that originated from distant hybridization between two different sections. These hybrid taxa demonstrate greater ecological adaptability than their ancestral species due to heterosis. We propose a hybrid speciation process model that can explain important evolutionary concerns.

Summary: Unlike conspicuous ochrophytes, many small and overlooked flagellates belonging to basally branching stramenopiles remain poorly characterized at the cellular or genomic level. This study describes four new species, including two new genera, of sediment-dwelling MAST-6 and provides updated phylogenomic tree of stramenopiles. The characterization of these flagellates is important due to their phylogenetic diversity and abundance in various environments.

Summary: Phylogenomic conflicts are widespread among genomic data, with most previous studies primarily focusing on nuclear datasets instead of organellar genomes. In this study, we investigated the phylogenetic conflicts within and between plastid and mitochondrial genomes using Potentilla as a case study. We found that both plastid and mitochondrial genomes divided Potentilla into eight highly supported clades, with two newly identified clades. Our results demonstrate that mitochondrial genes can fully resolve phylogenetic relationships among major clades of Potentilla and are not always linked with plastomes in evolutionary history.

Summary: Traditionally, differences between species have been associated with morphological variation. However, the discovery of cryptic diversity suggests that the evolution of distinct lineages can occur without morphological differences. Through genetic analysis, we found that a tropical montane plant lineage is composed of numerous unrecognized genetic groups that are not morphologically distinct. Geographic distance and topography play a crucial role in determining the genetic divergence of these groups.
