Summary: This study examines the role of dispersal and environmental filtering processes in plant species colonisation on islands based on functional traits. It finds evidence for selective filters on seed mass and leaf area but not plant height. Using individual trait analysis provides more insight into island floras than multivariate functional diversity indices or trait spaces. The study is important for understanding species colonisation and filtering processes on islands.

Summary: The influence of island dynamics and characteristics on different facets of plant diversity, including functional and phylogenetic diversity, is explored using barrier islands. Island area is found to be the best predictor for all diversity facets. Larger islands have higher functional and phylogenetic diversity, while smaller islands have lower diversity. Habitat heterogeneity also affects diversity, with increased competition on smaller islands leading to potential trade-offs between area and heterogeneity.

Summary: The tropical Asian and Australasian floras have a close relationship, and the distribution pattern of seed plants between them is vital worldwide. However, the evolutionary dynamics of these two floras are still unclear.

Summary: Amazonia serves as the main source of diversity for haemosporidian parasites in South America, but our understanding of their biogeographical processes and contributions from different areas of endemism is incomplete. This study investigates the spatiotemporal evolution of Plasmodium and Parahaemoproteus parasites and finds that dispersal is the main driver of Plasmodium diversification, while duplication is more frequent in Parahaemoproteus. The results show that the Inambari area is the primary source of Plasmodium diversity on Marajó Island, but the island receives more Parahaemoproteus lineages from Cerrado habitats than any Amazonian area. The unique dispersal patterns and host-shifting ability of each parasite genus may have facilitated their diversification across Amazonia, with deep evolutionary history potentially constraining their colonization of Marajó Island.

Summary: The study developed a framework to assess global island disharmony and identified significant variation in representational disharmony within and among plant families. Some families were generally over-represented, while others were generally under-represented on islands compared to their mainland source regions.

Summary: The Afromontane and Afroalpine areas in Africa are important biodiversity hotspots with rich plant endemics. This study focused on the plant genus Helichrysum and revealed its southern African origin and repeated colonization of the Afromontane and Afroalpine areas. The timing of these events coincide with mountain uplift and glacial cycles, suggesting their role in speciation and gene flow in the evolution of the Afroalpine flora.

Summary: The impact of modern humans on previously unoccupied island ecosystems and the extinction of Pleistocene megafauna are closely linked. However, current data does not support a direct association between Pleistocene hominin arrival and global extinctions, which are difficult to separate from environmental changes. It is not until the Holocene that significant changes in technology, dispersal, demography, and human behavior visibly affect island ecosystems.

Summary: Oceanic island floras are known for their unique morphological characteristics and provide examples of trait evolution. These morphological shifts are believed to be influenced by the biogeographical processes and evolutionary histories of oceanic islands. However, the mechanisms behind the distribution and diversity of plant functional traits remain unclear.

Summary: Repeated colonizations and resultant hybridization have increased lineage diversity on Muna Island. The history of multiple colonizations and hybridization events were reconstructed using genetic analyses. These mutual colonizations and introgressive hybridizations shaped the current biodiversity of the Oryzias woworae species group in this area.

Summary: The study reveals higher genetic diversity in the westernmost populations of East Africa, which show similarities with West African populations and the Ethiopian Simen Mountains. Multiple long-distance dispersals (LDD) of Festuca abyssinica among eastern African sky-islands were supported, with at least two dispersal events between the two sides of Africa.

Summary: This study conducted the first survey on the biodiversity of Peracarida from Trindade Island in Brazil, revealing new species and suggesting an Indo-Pacific origin for the genus based on phylogenetic and biogeographical analyses. A comparison with the closest Abrolhos Archipelago showed a high percentage of endemic species on Trindade Island.

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 investigates the immigration dynamics of tropical and subtropical Southeast Asian karst floras using Gesneriaceae as a proxy. The study reveals the timing and locations of immigration into these regions, with peak periods occurring in the Early Miocene and Late Eocene. The research also highlights the presence of immigrant pre-adapted lineages and descendants from local acid soil ancestors in Southeast Asian karst biodiversity. This study advances our understanding of the historical assembly of Southeast Asian karst floras.

Summary: The composition of native island assemblages may affect the richness of naturalized species, particularly on small islands. However, native species richness and the biogeographical factors of the island are still the main factors influencing the richness of naturalized species.

Summary: The flightless, phoretic insects of the tribe Meloini have widespread distribution and complex evolutionary relationships. Research on their molecular phylogenetics and taxonomic framework helps clarify controversial relationships within the group and reveals patterns of overseas dispersal in phoretic species of blister beetles. The high level of geographically unstructured haplotype diversity within taxa suggests multiple transmarine dispersal events in their evolutionary history.

Summary: Phylogenetic studies of Carex L. have shown that most subgenera and sections are para- or polyphyletic, yet taxonomists continue to use them for classification. The Global Carex Group argues that the historical and continued use of subgenera and sections helps organize lineages, create identification mechanisms, and recognize morphologically diagnosable lineages. While a global reclassification based on phylogenetic relationships is not yet possible, an intermediate step of implementing revised subgenera and using a combination of informally named clades and formally named sections has been taken to reflect current knowledge.

Summary: Target enrichment is increasingly used in phylogenomic studies. Paralogs are often recovered in data sets, and processing them can be prone to errors. Automated tree-based orthology inference methods can help study complex scenarios of polyploidy and reticulate evolution.

Summary: Olov Hedberg's work on the tropical alpine flora of the African sky islands has provided valuable insights. Recent studies suggest that colonization of the afroalpine habitat was dominated by long-distance dispersals, resulting in a rich flora of local endemics. The flora was shaped by strong intermountain isolation rather than ecological connectivity, and genetic data indicate a unique but fragile diversity that is vulnerable to extinction due to climate warming and human impact.

Summary: The colonization and diversification history of the afroalpine flora in Africa, which is highly endemic but species-poor, has been studied using phylogenetic relationships and molecular dating methods. Most lineages appear to have colonized the afroalpine during the last 5 or 10 million years, and the accumulation of species has increased exponentially toward the present. This study contributes to our understanding of the colonization processes on different tropical sky islands and provides insights into the shaping of their remarkable floras.
