Examining the utility of DNA barcodes for the identification of tallgrass prairie flora

open access: yesApplications in Plant Sciences, Volume 9, Issue 1, January 2021., 2021
Premise The tallgrass prairies of North America are one of the most threatened ecosystems in the world, making efficient species identification essential for understanding and managing diversity. Here, we assess DNA barcoding with high‐throughput sequencing as a method for rapid plant species identification.

Phylogenetic Analyses of Two Mitochondrial Metabolic Genes Sampled in Parallel from Angiosperms Find Fundamental Interlocus Incongruence [PDF]

open access: yes, 2008
Plant molecular phylogeneticists have supported an analytical approach of combining loci from different genomes, but the combination of mitochondrial sequences with chloroplast and nuclear sequences is potentially problematic. Low substitution rates in

The transformation of macrophyte‐derived organic matter to methane relates to plant water and nutrient contents

open access: yesLimnology and Oceanography, Volume 64, Issue 4, Page 1737-1749, July 2019., 2019
Abstract Macrophyte detritus is one of the main sources of organic carbon (OC) in inland waters, and it is potentially available for methane (CH4) production in anoxic bottom waters and sediments. However, the transformation of macrophyte‐derived OC into CH4 has not been studied systematically, thus its extent and relationship with macrophyte ...

Plastid phylogenomic analysis of green plants: A billion years of evolutionary history

open access: yesAmerican Journal of Botany, Volume 105, Issue 3, Page 291-301, March 2018., 2018
Premise of the Study For the past one billion years, green plants (Viridiplantae) have dominated global ecosystems, yet many key branches in their evolutionary history remain poorly resolved. Using the largest analysis of Viridiplantae based on plastid genome sequences to date, we examined the phylogeny and implications for morphological evolution at ...

Omnivorous Diets of Sympatric Duck Species in a Subtropical East Asia Wetland Unveiled by Multi‐Marker DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
The East Asian–Australasian Flyway (EAAF) is experiencing significant declines in migratory waterbird populations. Understanding the foraging ecology of waterbird species, particularly ducks, is crucial for monitoring and protecting their food sources and wetland habitats.
