NAMERS: a purpose-built reference DNA sequence database to support applied eDNA metabarcoding [PDF]

Metabarcoding and Metagenomics
Applied eDNA metabarcoding is increasingly being considered as a tool to inform management decisions, regulations, or policy development. Because these downstream considerations are coming to the forefront of eDNA applications, optimizing workflow ...

DNA Authentication of St John’s Wort (Hypericum perforatum L.) Commercial Products Targeting the ITS Region [PDF]

, 2019
open access articleThere is considerable potential for the use of DNA barcoding methods to authenticate raw medicinal plant materials, but their application to testing commercial products has been controversial.

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

Nordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Technical challenges in the implementation of macroinvertebrate DNA metabarcoding in river biomonitoring: A case study from peninsular Spain—Advantages, limitations and roadmap

Ecological Solutions and Evidence
European Union member states are required to monitor the ecological status of their water bodies. The existing official protocols and indices for routine biomonitoring are usually based on the morphological identification of different groups of indicator

ranacapa: An R package and Shiny web app to explore environmental DNA data with exploratory statistics and interactive visualizations. [PDF]

, 2018
Environmental DNA (eDNA) metabarcoding is becoming a core tool in ecology and conservation biology, and is being used in a growing number of education, biodiversity monitoring, and public outreach programs in which professional research scientists engage

Sources of variation in small rodent trophic niche: New insights from DNA metabarcoding and stable isotope analysis [PDF]

, 2011
Intraspecific competition for food is expected to increase the trophic niche width of consumers, defined here as their diet diversity, but this process has been little studied in herbivores.

Stratified sampling enhances the understanding of bat–fruit networks in the southern Atlantic Forest

Oikos, EarlyView.
Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

Metabarcoding of marine zooplankton: prospects, progress and pitfalls [PDF]

, 2016
Metabarcoding (large-scale taxonomic identification of complex samples via analysis of one or few orthologous DNA regions, called barcodes) is revolutionizing analysis of biodiversity of marine zooplankton assemblages.

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Development of a multigenic metabarcoding of prokaryotic microbiota: application to Bacteria and Archaea of agronomical interest encountered in the rice rhizosphere of Camargue [PDF]

, 2017
It is our hypothesis that soil and plant microbiota are playing an eminent role in shaping both natural ecosystems and agricultural production systems. It is now widely admitted that bacterial communities show a great diversity in the rhizosphere and in ...
