Summary: The study reveals that endemic species started to colonize the TP as early as 55 million years ago, with the main colonization phase increasing around 15 million years ago and peaking after 6 million years. The major source areas for endemic TP species include the Hengduan Mountains, the Himalayas, and Central Asia. Elevation difference has the strongest effect on the source areas, followed by geographical distance. Significant differences were found among vertebrate classes in terms of spatio-temporal origins and potential drivers of endemic TP species.

Summary: This study examines the comparison of the Dispersal-Extinction-Cladogenesis (DEC) model and a modification of it, DEC+J, in historical biogeography. The results show that DEC+J provides better model fit on most datasets, while the DEC model is statistically inadequate in situations where most species have single-area geographical ranges. The comparison of DEC and DEC+J is found to be statistically valid according to the criteria recommended by Ree and Sanmartin.

Summary: This study investigates the origin of the fern genus Ctenitis in the Hawaiian Islands and suggests a single long-distance dispersal event from the Neotropics. The colonization of the islands is estimated to have occurred around 3-4 million years ago, consistent with the ages of the main islands. The late arrival and potential limited ecological niches may have hindered diversification of the genus.

Summary: Carex subgenus Psyllophorae is a fascinating study group with early diversification and disjunct distribution, showing the role of historical geo-climatic events in evolutionary history, particularly in South America. Divergence away from primary Gondwanan vicariance hypotheses and long-distance dispersal-mediated allopatric diversification are key aspects of the group's evolution. The trans-Pacific colonization event and niche conservatism in section Junciformes are also noteworthy findings.

Summary: Speciation, dispersal, and extinction are crucial for understanding the spatial and temporal dynamics of biodiversity. However, due to incomplete fossil records, determining the dynamics of these processes and the factors influencing them is challenging. In this study, the dispersal-extinction-sampling (DES) model is expanded to incorporate heterogeneity in fossil sampling, reconstruct diversity trajectories, and link range evolution rates with biological and environmental covariates. The validated framework demonstrates the power of likelihood-based model testing in discerning the effects of biotic and abiotic factors on dispersal and extinction. The study also highlights the influence of trait-dependent models in accurately estimating parameter values.

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: This article presents a comprehensive molecular phylogenetic study of the diverse moss beetle genera in the family Hydraenidae. The research suggests that these beetles originated in Africa and Madagascar during the mid-Cretaceous, and their biogeographic history in the Southern Hemisphere was shaped by both vicariant and dispersal processes as well as extinctions. The study also reveals multiple shifts in habitat occupancy across the phylogeny, including the independent origins of terrestrial and humicolous taxa in different regions.

Summary: Erratic boulders in the calcareous Swiss lowlands serve as exclusive habitats for regionally critically endangered fern, various bryophyte species, and numerous lichens. Utilizing ddRAD technology, the study revealed lower multilocus genotype diversity for both Asplenium septentrionale and Hedwigia ciliata on boulders compared to mainland populations, suggesting rare successful colonization for the former due to intrinsic factors like long-distance dispersal and selfing.

Summary: The epiphytic fern genus Microgramma, mainly found in the Neotropics, displays a wide range of variation in morphology and ecology not seen in closely related genera. Recent studies have revised the circumscription of Microgramma based on phylogenetic evidence, leading to the identification of five clades that do not align with previous infrageneric classification systems. Homoplastic traits, including leaf dimorphism, are found within the genus, along with ant-plant associations in two lineages, suggesting complex evolutionary patterns. Long-distance dispersal events are hypothesized to explain the distribution of certain species, such as Microgramma lycopodioides in the Neotropics and M. mauritiana in Africa, highlighting the importance of biogeography in the evolution of this lineage.

Summary: Research on bird species diversity and composition on tropical shelf islands in Southeast Asia found that post-LGM effects on diversity are minimal, with present-day island characteristics such as area, distance to the mainland, and proportion of land surrounding the island within a 10 km radius being more explanatory. Avifaunal diversity is maintained by high immigration rates, especially on small islands, with over-water dispersal limited to short distances among Sundaic birds.

Summary: The Andean uplift has played a crucial role in shaping the biogeography of the Neotropical biota, with Nasa genus being a key player in this process. This study provides a detailed phylogenetic reconstruction of Nasa, revealing four well-supported clades with different distribution patterns, indicating a complex evolutionary history spanning over 50 million years. The Amotape-Huancabamba Zone (AHZ) is identified as a major center of diversification for Nasa, while the central Andes are considered the likely area of origin for the genus.

Summary: This study revealed a greater morphological diversity in the filmy fern genus Trichomanes than traditionally recognized, proposing a new subgenus Afrotrichomanes for the Afro-Malagasy taxa. The origins of Palaeotropical species in the genus are suggested to have occurred through both recent colonization from the Neotropics and a possible Mesozoic vicariance event. The low species diversity of the genus in the Afro-Malagasy region was discussed.

Summary: Through morphological, morphometric, and molecular phylogenetic analyses, it was found that V. collariata is distinct from other species, and that V. radicans, V. speciosa, V. gigantea, and the African specimens cannot be distinguished morphologically and morphometrically. The Neotropical specimens of V. radicans, V. speciosa, and V. gigantea are genetically distinct and are supported as distinct species. African specimens form a separate clade sister to V. gigantea and are described as a new species, Vandenboschia confusa, based on the presence of a well-developed wing on the stipe.

Summary: Assessment methods for estimating conservation status and building Red Lists are valuable tools, especially in French Overseas Territories where out-dated or absent Red Lists and anthropogenic pressures pose threats to endemic species. This study conducted a pre-assessment of conservation status for endemic plants in various territories, comparing different methods used and discussing adaptations for smaller territories. The Random Forest algorithm and range-size-based methods showed the highest accuracy in attributing conservation status, revealing that up to 60% of endemic flora in the FOTs is potentially threatened due to range restriction and anthropogenic pressures.
