Marine biodiversity patterns in coastal Australian waters revealed by a three-year environmental DNA survey
<p><strong>Aim</strong></p> <p>To test the capacity of eDNA to characterise the spatial and seasonal patterns found within a range of zooplankton communities, and investigate links with concurrent abiotic data collected as part of Australia's Integrated Marine Observing System (IMOS) programme.</p> <p><strong>Location</strong></p> <p>Samples were sourced seasonally for three years from nine Pan-Australian marine sites (n=90).</p> <p><strong>Methods</strong></p> <p>Here we apply a multi-assay metabarcoding approach to environmental DNA extracted from a rare long-term collection of bulk plankton samples. Six assays (targeting both the 16SrRNA and COI genes) were used to amplify and sequence the zooplankton diversity found within each sample. The data generated from each assay was filtered and clustered into OTUs prior to analysis. Abiotic IMOS data collected alongside the plankton collection enabled us to explore the physical and chemical drivers of community composition.</p> <p><strong>Results</strong></p> <p>The eDNA metabarcoding generated over 25 million sequences, identified in excess of 500 distinct taxa and detected clear spatial differences in marine metazoan communities. We found that site and sea surface temperature are the most consistent predictors of differences between zooplankton communities. We detected endangered and invasive species such as the bryozoan Membranipora membranace and the mollusc Maoricolpus roseus, and seasonal occurrences of species such as humpback whales (Megaptera novaeangliae). We also estimated the number of samples required to ensure robust marine eDNA metabarcoding biomonitoring programs into the future.</p> <p><strong>Main Conclusion</strong></p> <p>Our results demonstrate the ability of eDNA to capture and map zooplankton community changes in response to seasonal and spatial stressors and provide vital evidence to environmental stakeholders. We confirm that eDNA offers a practical opportunity for an ecosystem-wide approach to the long-term biomonitoring and understanding marine biomes where a morphological approach is not feasible.</p>
Tracking freshwater browning and coastal water darkening from boreal forests to the Arctic Ocean
<p></p> <p class="MsoNormal"><span>The forest cover of Northern Europe has been steadily expanding during the last 120 years. More terrestrial vegetation and carbon fixation leads to more export to surface waters. This may cause freshwater browning, as more degraded plant-litter ends up as chromophoric (coloured) dissolved organic matter. Although most freshwater ultimately drains to coastal waters, the link between freshwater browning and coastal water darkening is poorly understood. Here, we explore this relationship through a combination of centennial records of forest and coastal water clarity, contemporary optical measurements in lakes and coastal waters, as well as an ocean drift model. We suggest a link between forest cover in Northern Europe and coastal water clarity in the Baltic, Kattegat and Skagerrak Sea and show how brown coloured freshwater from Northern European catchments can dictate coastal water clarity across thousands of kilometres, from the Baltic lakes to the Barents Sea.</span></p>
