Summary: Molecular and genomic studies have shown that Mycobacterium tuberculosis Lineage 4 (L4) emerged in Europe and spread globally through trade routes, colonial migration, and historical connections. This study investigates the distribution of L4 in Southeast Asia and surrounding countries using public genomic data. The findings indicate that specific sub-lineages of L4 are predominantly found in East and Southeast Asia, suggesting a regional dispersal pattern. Further sampling and research are needed to determine the exact routes of dispersal.

Summary: Physiographic changes, such as river catchment drainage reorganisations, played an important role in Quaternary species diversification in Sundaland, Southeast Asia, according to simulations using combined landscape evolution and connectivity models. The changes have fragmented the environment into multiple habitats connected by migratory corridors. These results support the theory that rapidly evolving physiography could foster Quaternary biodiversification across Southeast Asia.

Summary: Southeast Asia is a hotspot of terrigenous organic carbon export to the ocean, with around 10% of global land-to-ocean riverine flux. Research in the central Sunda Shelf reveals a large input of terrigenous dissolved organic carbon (tDOC) during the Southwest Monsoon, leading to seasonal acidification. Isotope mass balance calculations show that 60%-70% of the original tDOC input is remineralized in coastal waters, contributing to CO2 efflux. Additionally, incubation experiments suggest that 30%-40% of tDOC is relatively refractory and may be exported to the open ocean.

Summary: Through studying the population genetic structure and diversity of two pine species, it is found that tropical pine species and subtropical pine species have different evolutionary processes and distribution ranges under the influence of past climate change in SEA. The subtropical Pinus yunnanensis shows significant gene flow, while the tropical Pinus kesiya exhibits strong population structure. There is a wide hybrid zone between the two species in southern Yunnan. Predictions indicate that the range of Pinus kesiya will decrease under future climate change. This study highlights the different evolutionary trajectories of pine species in SEA compared to high latitude species, emphasizing the urgent need for conservation efforts in this fragmented landscape.

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.
