Under the karst: detecting hidden subterranean assemblages using eDNA metabarcoding in the caves of Christmas Island, Australia

open access: yesScientific Reports, 2020
Subterranean ecosystems are understudied and challenging to conventionally survey given the inaccessibility of underground voids and networks. In this study, we conducted a eukaryotic environmental DNA (eDNA) metabarcoding survey across the karst ...

Water, water everywhere: environmental DNA can unlock population structure in elusive marine species [PDF]

open access: yesRoyal Society Open Science, 2018
Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a number of marine ...

Exploring genome wide bisulfite sequencing for DNA methylation analysis in livestock: a technical assessment [PDF]

open access: yes, 2014
peer-reviewedRecent advances made in “omics” technologies are contributing to a revolution in livestock selection and breeding practices. Epigenetic mechanisms, including DNA methylation are important determinants for the control of gene expression in ...

MiFish, a set of universal PCR primers for metabarcoding environmental DNA from fishes: detection of more than 230 subtropical marine species [PDF]

open access: yesRoyal Society Open Science, 2015
We developed a set of universal PCR primers (MiFish-U/E) for metabarcoding environmental DNA (eDNA) from fishes. Primers were designed using aligned whole mitochondrial genome (mitogenome) sequences from 880 species, supplemented by partial mitogenome ...

Environmental variables, habitat discontinuity and life history shaping the genetic structure of Pomatoschistus marmoratus [PDF]

open access: yes, 2014
Coastal lagoons are semi-isolated ecosystems exposed to wide fluctuations of environmental conditions and showing habitat fragmentation. These features may play an important role in separating species into different populations, even at small spatial

Fecal sample collection methods and time of day impact microbiome composition and short chain fatty acid concentrations

open access: yesScientific Reports, 2021
Associations between the human gut microbiome and health outcomes continues to be of great interest, although fecal sample collection methods which impact microbiome studies are sometimes neglected. Here, we expand on previous work in sample optimization,

Screening Universal COⅠ Primers for eDNA Metabarcoding of Freshwater Fishes on Hainan Island

open access: yesProgress in Fishery Sciences, 2023
The known universal primers for environmental DNA (eDNA) metabarcoding of fish are mainly located in the mitochondrial ribosome gene regions. Not only are the reference sequences insufficient but also some relative fish species could not be identified ...

An MLSA-based online scheme for the rapid identification of Stenotrophomonas isolates [PDF]

open access: yes, 2011
An online scheme to assign Stenotrophomonas isolates to genomic groups was developed using the multilocus sequence analysis (MLSA), which is based on the DNA sequencing of selected fragments of the housekeeping genes ATP synthase alpha subunit (atpA ...
