Molecular metrics to monitor ecological status of large rivers: Implementation of diatom DNA metabarcoding in the Joint Danube Survey 4

Ecological Indicators
The Joint Danube Survey (JDS) is a regular transnational survey to monitor the quality of the Danube and its main tributaries, in accordance with the EU Water Framework Directive.

Validating environmental DNA metabarcoding for marine fishes in diverse ecosystems using a public aquarium

Environmental DNA, 2020
Environmental DNA metabarcoding has been widely touted as a powerful tool for monitoring biodiversity in marine ecosystems. However, this method still requires thorough validation and standardization before it can be widely applied for ecological ...

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

Metabarcoding of freshwater invertebrates to detect the effects of a pesticide spill [PDF]

, 2017
Biomonitoring underpins the environmental assessment of freshwater ecosystems and guides management and conservation. Current methodology for surveys of (macro)invertebrates uses coarse taxonomic identification where species-level resolution is difficult

Simplifying species‐interaction models by grouping parameters: optimal groupings differ between effects and responses

Oikos, EarlyView.
Most ecological models of species interactions require many parameters, making them expensive to fit to experimental or observational data. To reduce the number of parameters, species are often divided into groups a priori, for example on the basis of functional or phylogenetic similarity, and species within these groups are assumed to behave ...

DNA metabarcoding for high-throughput monitoring of estuarine macrobenthic communities [PDF]

, 2017
Morphology-based profling of benthic communities has been extensively applied to aquatic ecosystems’ health assessment. However, it remains a low-throughput, and sometimes ambiguous, procedure.

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,

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

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
