However, knowledge about shift with impact change using genomic data remains rare.

Summary Evergreen broad‐leaved forests (EBLFs) are dominated by a monsoon climate and form distinct biome in East Asia with notably high biodiversity. However, the origin evolution of Asian EBLFs (EAEBLFs) remain elusive despite estimation divergence times for various representative lineages. Using 72 selected generic‐level characteristic lineages, we constructed an integrated lineage accumulation rate (LAR) curve based on their crown ages. According to crown‐based LAR, EAEBLF was identified at least as early Oligocene ( c. 31.8 million years ago (Ma)). The genera peaked 25.2 6.4 Ma, coinciding two intensification periods – Miocene Pliocene boundaries, respectively. Moreover, LAR highly correlated precipitation region negatively global temperature, revealed through time‐lag cross‐correlation analyses.

Abstract Lindera obtusiloba Blume is the northernmost tree species in family Lauraceae, and it a key understanding evolutionary history of this family. The L. East Asia has diverged into Northern Southern populations, which are geographically separated by an arid belt. Though morphological differences between populations have been observed well documented, intraspecific variations at plastomic level not systematically investigated to date. Here, ten chloroplast genomes individuals were sequenced analyzed along with three publicly available plastomes. Comparative analysis suggests that both share similar overall structure, gene order, GC content their plastomes although size plasome variability do vary two populations. relatively larger while population possesses higher variability, could be attributed complexity geological environments South. Phylogenomic analyses also support split clades among individuals.

The illegal trade of tropical timber constitutes a major and persistent environmental problem. Since the detection fraud in documents remains challenging, forensic tools that can independently trace origin are needed. In this study, we evaluated potential chloroplast genome (plastome) as genetic tool to verify claimed species geographic from Azobé (Lophira alata), an intensively exploited threatened tree species. We sampled 480 trees Lophira alata congeneric L. lanceolata across nine countries Central West Africa. Sampling included 15 logging concessions Cameroon, Gabon Republic Congo. DNA was isolated cambium or leaf tissue, complete plastid genomes were assembled. A total 228 SNPs 436 retained, which formed 35 pDNA haplotypes (with length 179 SNPs). two shared one haplotype contained several closely related haplotypes. For alata, detected moderately strong correlation between spatial distances. Two widely spread core Africa, while others more spatially constrained endemic, for example, (potentially cryptic species) Northern distribution revealed clear structure. Some potentially hamper site distinction wood samples, but still reveal their wider region origin. regions where endemic present, differentiation may be successful at finer scales.
