Population Status and Recovery Potential of <i>Dalbergia odorifera</i> Under Anthropogenic Disturbance: Evidence From Hainan Island, China. [PDF]

open access: yesEcol Evol
To explore the survival status and dynamics of wild populations of Dalbergia odorifera on Hainan Island, this study adopts field sampling combined with demographic analysis such as age class division and life table analysis. Results show that although the population is of growing type with abundant young individuals, there are structural gaps and false

Leveraging target enrichment and genome skimming (Hyb-Seq) of herbarium collections to unlock timber DNA barcoding. [PDF]

open access: yesAppl Plant Sci
Abstract Premise DNA barcoding for timber species identification requires comprehensive reference datasets, informative DNA barcodes, and cost‐effective protocols. We developed a workflow leveraging Hyb‐Seq (target capture sequencing and genome skimming) to address these challenges, and we tested it on four genera from the mahogany family (Meliaceae ...
