Summary Tropical Southeast Asia, which harbors most of the Musaceae biodiversity, is one species‐rich regions in world. Its high degree endemism shaped by region's tectonic and climatic history, with large differences between northern Indo‐Burma Malayan Archipelago. Here, we aim to find a link diversification biogeography geological history Asian subcontinent. The family (including five Ensete , 45 Musa Musella species) was dated using phylogenetic framework encompassing 163 species from all Zingiberales families. Evolutionary patterns within were inferred ancestral area reconstruction rate analyses. All three genera – originated during early Eocene. dispersed ‘northwest southeast’ into Asia only few back‐dispersals towards Indo‐Burma. colonization events Archipelago subcontinent are clearly linked region. able colonize region east Wallace's line after availability emergent land late Miocene onwards.

Cymbidium (Orchidaceae: Epidendroideae), with around 60 species, is widely-distributed across Southeast Asia, providing a nice system for studying the processes that underlie patterns of biodiversity in region. However, phylogenetic relationships have not been well resolved, hampering investigations species diversification and biogeographical history this genus. In study, we construct plastome phylogeny 56 four well-resolved major clades, which provides framework rate analyses. Molecular dating analyses show likely originated region spanning northern Indo-Burma to eastern Himalayas during early Miocene (∼21.10 Ma). It then rapidly diversified into clades East Asia within approximately million years middle Miocene. spp. migration adjacent regions (Borneo, Philippines, Sulawesi) primarily occurred Pliocene-Pleistocene period.

The genus Nodularia poses a significant challenge to traditional species classification and identification due its highly convergent variable shells, rendering it one of the most intricate groups within family Unionidae. Fortunately, progress has been made by researchers in recent years regarding validity phylogeny this group based on molecular data. However, inadequate exploration regional constraints inherent limitations research methodologies remains crucial factor contributing underestimation diversity. In study, new freshwater mussel from Qingshui River Nanning City, Guangxi Province, China, guiensis sp. nov. , is described shell morphology, anatomical characters, phylogenetics. Mitochondrial phylogenomic analyses reveal following phylogenetic relationships: ((( hanensis + micheloti ) dorri ( breviconcha huana fusiformans (( nuxpersicae nipponensis dualobtusus douglasiae ))))))). discovery taxon further enhances diversity level China also highlights necessity for comprehensive surveys unexplored regions order potentially unveil additional taxa future.

Distributed across two continents and thousands of islands, the Asian tropics are among most species-rich areas on Earth. The origins this diversity, however, remain poorly understood. Here, we reveal classify contributions individual tropical regions to their overall diversity by leveraging species-level phylogenomic data new fossils from palm lineage, rattans relatives (Arecaceae, Calamoideae). Radiators (Borneo) generate distribute incubators (Indochina, New Guinea, Sulawesi) produce in isolation, corridors (Java, Maluku, Sumatra, Thai-Malay Peninsula) connect neighboring regions, accumulators (Australia, India, Palawan, Philippines) acquire generated elsewhere. These contrasting can be explained differences region size elucidating how unique island-dominated geography drives outstanding biodiversity.

Lack of knowledge plant flammability has impeded the understanding ecological feedbacks between fire and vegetation. We measured traits 263 woody species in subtropical semi-humid regions China to identify strategies assess impact frequency on different syndromes that were defined as combinations leaves bark. The results indicated 40.0%, 39.1% 20.9% had hot-, fast- low-flammable leaves, respectively, 28.2%, 35.7% 36.1% bark, respectively. Tree (47.5%) a higher percentage strategy separation bark than large shrubs (19.7%) shrub (18.2%). Community-level evidence showed with or hot-flammable may gain notable advantage repeated fires. Structural equation models more frequently burned forests associated infertile soil, enrichment lower richness, subsequently leading favour flammable species. Thus, positive feedback loop would be generated dominance communities frequency, fostering characteristics regimes evergreen broadleaved forests.
