Méthodes d'échantillonnage
We collected 1 L surface samples from each site every 30 minutes for the duration of time the rocky intertidal was exposed on 28 January 2022, using single-use enteral feeding pouches (Covidien, Dublin, Ireland). The sampling volume used, 1 L, has been shown to be sufficient for detecting a representative range of marine organisms in nearshore locations and is commonly used in aquatic eDNA studies. Sampling commenced at 11:30 PST; at each site, samples were collected from a consistent position across time points. We attached a sterile 0.22 μm pore size Sterivex cartridge (MilliporeSigma, Burlington, MA, USA) to the tubing of each feeding pouch, allowing samples to be immediately gravity filtered in the field. While gravity filtering (1-2 hours per sample), samples were shaded with an awning to prevent any degradation by sunlight. One sample fell during gravity filtration, resulting in a missing sample from S1 at 16:00 PST. At three time points at the beginning and end of the sampling period as well as at low tide (at 14:00 PST), we collected triplicate 1 L samples from each location as biological replicates. At the beginning and end of the sampling period, we also filtered 1 L MilliQ water via the procedure described above to serve as negative field controls. Additionally, using an Orion Model 1230 meter (Orion Research Inc., Beverly, MA, USA), we recorded temperature and salinity in each location directly after samples were collected. Once finished filtering, Sterivex cartridges were dried by pushing air through them using a sterile 3 mL syringe, capped, placed in sterile Whirl-Pak bags (Whirl-Pak, Madison, WI, USA). Then, samples were stored in a cooler on ice until transported back to the laboratory at the end of the sampling period. Samples were transferred to a -20°C freezer for up to 18 days, at which time they were processed to extract nucleic acids from the captured materials. This sampling scheme resulted in 53 field samples, processed as technical replicates in the laboratory (resulting in the 159 events published here).
| Etendue de l'étude | 53 water samples were collected in the rocky intertidal at Pillar Point, Half Moon Bay, California, USA on 28 January 2022. Within Pillar Point, we sampled at three discrete locations: two individual tide pools with a range of physical connectivity (Tide Pool 1, S1: 37.495306°, -122.498744°; Tide Pool 2, S2: 37.494992°, -122.498955°) and an equidistant location (Nearshore, N: 37.495288°, -122.499198°) where there was well-mixed offshore water for the duration of the tidal cycle. All three locations are about 40 meters apart from one another, and are fully isolated at low ride but otherwise interconnected. Ecologically, S1 is more characteristic of the high intertidal, and S2 is more characteristic of the low intertidal. The locationID field identifies the three specific samples locations. |

| Objet | Abstract: While the utility of environmental DNA (eDNA) metabarcoding surveys for biodiversity monitoring continues to be demonstrated, the spatial and temporal variability of eDNA, and thus the limits of the differentiability of an eDNA signal, remains under-characterized. In this study, we collected eDNA samples from distinct micro-habitats (~40 m apart) in a rocky intertidal ecosystem over their exposure period in a tidal cycle. During this period, the micro-habitats transitioned from being interconnected, to physically isolated, to interconnected again. Using a well-established eukaryotic (cytochrome oxidase subunit I) metabarcoding assay, we detected 415 species across 28 phyla. Across a variety of univariate and multivariate analyses, using exclusively taxonomically-assigned data as well as all detected amplicon sequence variants (ASVs), we identified unique eDNA signals from the different micro-habitats sampled. This differentiability paralleled expected ecological gradients and increased as the sites became more physically disconnected. Our results demonstrate that eDNA biomonitoring can differentiate micro-habitats in the rocky intertidal only 40 m apart, that these differences reflect known ecology in the area, and that physical connectivity informs the degree of differentiation possible. These findings showcase the potential power of eDNA biomonitoring to increase the spatial and temporal resolution of marine biodiversity data, aiding research, conservation, and management efforts. |
