Data from: Drop it all: Extraction-free detection of non-indigenous marine species through optimized direct-droplet digital PCR
<p>Molecular biosecurity surveillance programs increasingly use environmental DNA (eDNA) for detecting marine non-indigenous species (NIS). However, the current molecular detection workflow is cumbersome, prone to errors and delays, and is limited in providing knowledge about eDNA beyond the spatial and temporal extent of the sampling. These limitations can hinder management efforts and restrict the "opportunity window" for a rapid response to new marine NIS incursions. Emerging innovative field-deployable digital droplet PCR (ddPCR) systems offer improved workflow efficiency by autonomously analyzing targeted free-floating extra-cellular eDNA (free-eDNA) signals. Despite their potential, these systems have not been tested in marine environments. Thus, an aquarium study was conducted with three distinct marine NIS: <span>the Mediterranean fanworm <em>Sabella spallanzanii</em>, the ascidian clubbed tunicate <em>Styela clava</em>, and the brown bryozoan <em>Bugula neritina</em></span> to evaluate the detectability of free-eDNA in seawater. The detectability of targeted free-eDNA was assessed by directly analyzing aquarium water samples using an optimized species-specific ddPCR assay, without filtration or DNA extraction, so-called, "direct-ddPCR". The results demonstrated the consistent detection of <em>Sabella spallanzanii</em> and <em>Bugula neritina</em> free-eDNA when these organisms were present in high abundance. Once organisms were removed, the free-eDNA signal exponentially declined, noting that free-eDNA persisted between 24-72 hours. Results indicate that organism biomass, specimen characteristics (e.g., stress and viability), and species-specific biological differences may influence free-eDNA detectability. These results are critical for implementing <em>in-situ</em> nucleic acid automated continuous sensing systems for marine biosurveillance, enabling point-of-need detection and <span>rapid management response to biosecurity threats. </span></p>
A trait-based approach to assess niche overlap and functional distinctiveness between non-indigenous and native species
<p><span>Our understanding of the community assembly processes acting on non-indigenous species (NIS), as well as the relationship with native species is limited, especially in marine ecosystems. To overcome this knowledge gap we here develop a trait-based approach based on the functional distinctiveness metric to assess niche overlap between NIS and native species, using high-resolution data on benthic invertebrate communities in the Baltic Sea. Our results </span><span>show that NIS retain a certain degree of similarity with native species, but display one or a few singular unique traits (e.g., bioturbation ability). Furthermore, we demonstrate that community assembly processes, including both environmental filtering and limiting similarity affect NIS establishment, but that their effects may be highly context dependent, as illustrated by pronounced spatial patterns in distinctiveness. </span><span>Finally, our trait-based approach provides a generic framework applicable to other areas and organisms, to better understand and address biological invasions. </span></p>
