Abstract

Microplastics are now ubiquitous in freshwater environments. As most previous research has focused on species-specific effects, little is known about their impacts at higher levels of ecological organization, such as freshwater communities and their associated ecosystem functions. To fill this knowledge gap, an outdoor freshwater mesocosm experiment was used to determine the effects of (i) microplastic type: conventional versus bio-based biodegradable (ii) concentration of microplastic particles and (iii) nutrient enrichment in 40 outdoor pond mesocosms. The independent and interactive effects of these treatments on pelagic community structure (taxonomic richness and composition) and ecosystem functioning (phytoplankton standing stock, periphyton productivity and leaf litter decomposition) were assessed. Neither taxonomic richness, community composition, phytoplankton standing stock or aspects of ecosystem functioning were affected by exposure to the experimental treatments. These findings indicate that predicted negative impacts of microplastics indication by laboratory studies may not readily be realized at the ecosystem scale.

Abstract

The bioassessment of aquatic ecosystems is currently based on various biotic indices that use the occurrence and/or abundance of selected taxonomic groups to define ecological status. These conventional indices have some limitations, often related to difficulties inmorphological identification of bioindicator taxa. Recent development of DNA barcoding and metabarcoding could potentially alleviate some of these limitations, by using DNA sequences instead of morphology to identify organisms and to characterize a given ecosystem. In this paper,we review the structure of conventional biotic indices, andwe present the results of pilotmetabarcoding studies using environmental DNA to infer biotic indices. We discuss the main advantages and pitfalls of metabarcoding approaches to assess parameters such as richness, abundance, taxonomic composition and species ecological values, to be used for calculation of biotic indices.We present some future developments to fully exploit the potential of metabarcoding data and improve the accuracy and precision of their analysis. We also propose some recommendations for the future integration of DNA metabarcoding to routine biomonitoring programs
