Abstract BACKGROUND The black bean bug Brachyplatys subaeneus is a crucial legume crop pest native to Asia. It has been introduced the Americas and rapidly in tropical subtropical regions, where it poses serious threat local crops. However, population structure invasive sources of this have never studied, hindering effective monitoring management. Here, we investigated genetic populations based on nuclear SNP data relationship between Panama samples COI 16S rRNA sequences. In addition, constructed ecological niche models predict its potential invasion areas. RESULTS We found that B. comprised three geographic lineages (NO, PH SO) within range, with strong differentiation these lineages. Genetic relationships mitochondrial DNA indicated used study were derived from NO lineage. Ecological modelling shows wide range suitable habitats northern central regions South America, suggesting expand further south America. CONCLUSION This revealed inferred possible geographical origin populations, areas for bug. Our findings could provide new insights into management efforts pest. © 2025 Society Chemical Industry.

Abstract Aim Understanding the biotic and abiotic mechanisms underlying generation maintenance of biogeographic transitions represent long‐standing topics in evolutionary biology. The Isthmus Kra (IOK) divides Sundaland Indochina constitutes a poorly characterized terrestrial transition. Here we looked at population genetic structure three species that are distributed across IOK to gain insights into drivers have shaped this transition regional diversification patterns. Location Tropical east Asia: Indochina. Taxa Callosciurus caniceps , Tamiops mcclellandii Dremomys rufigenis‐ornatus complex (Mammalia: Rodentia: Sciuridae). Methods We generated complete mitogenomes sequences 11 nuclear intron fragments from 61 67 museum specimen samples, respectively. assessed by constructing Maximum Likelihood mitogenome phylogenies (IQTREE2), marker haplowebs conspecificity matrices (HaplowebMaker CoMa). estimated divergence dates through Bayesian phylogenetic inference (BEAST2) put these results context climatic geological history. Results High levels mitochondrial were identified all squirrels. Lineage turnover was consistent with two major mammal distribution near Kangar‐Pattani Line juncture between Thai‐Malay peninsula mainland. Divergence lineages late Pliocene/ early Pleistocene for taxa. Older Miocene/Pliocene divergences within D. T. which paraphyletic. Main Conclusions Sundaic Indochinese populations possibly diverged allopatric habitat refugia or around mountains during periods increased aridity evergreen forest contraction.

Opening the door to greater phylogeographic inference in Southeast Asia: Comparative genomic study of five codistributed rainforest bird species using target capture and historical DNA

Ecology and Evolution, Journal Year: 2020, Volume and Issue: 10(7), P. 3222 - 3247

Published: March 6, 2020

Abstract Indochina and Sundaland are biologically diverse, interconnected regions of Southeast Asia with complex geographic histories. Few studies have examined phylogeography bird species that span the two because inadequate population sampling. To determine how barriers/events disparate dispersal potential influenced structure, gene flow, demographics occupy entire area, we studied five largely codistributed rainforest species: Arachnothera longirostra , Irena puella Brachypodius atriceps Niltava grandis Stachyris nigriceps . We accomplished relatively thorough sampling data collection by sequencing ultraconserved elements (UCEs) using DNA extracted from modern older (historical) specimens. obtained a genome‐wide set 753–4,501 variable loci 3,919–18,472 single nucleotide polymorphisms. The formation major within‐species lineages occurred within similar time (0.5–1.5 mya). Major patterns in genetic structure consistent habitat requirements study species. A break across Isthmus Kra was shared only hill/submontane insectivores ( N. S. ). Across Sundaland, there is little B. which eurytopic partially frugivorous often utilizes forest edges. Two other species, A. I. possess highly divergent populations peripheral Sunda Islands (Java and/or Palawan) India. These probably intermediate abilities allowed them to colonize new areas, then remained isolated subsequently. also observed an east–west very different potential. By analyzing high‐throughput data, our provides unprecedented comparative perspective on process avian divergence Asia, determined geography, characteristics, stochastic nature vicariance events.
